    Requirements for Child-Resistant Packaging; Household Products 
    Containing Methacrylic Acid
    
    AGENCY: Consumer Product Safety Commission.
    
    ACTION: Proposed rule.
    
    -----------------------------------------------------------------------
    
    SUMMARY: The Commission is proposing a rule to require child-resistant 
    (``CR'') packaging for liquid household products containing more than 5 
    percent or more methacrylic acid (weight-to-volume) in a single 
    package. The Commission has preliminarily determined that child-
    resistant packaging is necessary to protect children under 5 years of 
    age from serious personal injury and serious
    
    [[Page 71801]]
    
    illness resulting from handling or ingesting a toxic amount of 
    methacrylic acid. The Commission is specifically concerned about nail 
    care products containing methacrylic acid, the only household product 
    the Commission has confirmed to contain methacrylic acid. The 
    Commission takes this action under the authority of the Poison 
    Prevention Packaging Act of 1970.
    
    DATES: Comments on the proposal should be submitted no later than March 
    15, 1999.
    
    ADDRESSES: Comments should be mailed to the Office of the Secretary, 
    Consumer Product Safety Commission, Washington, D.C. 20207, or 
    delivered to the Office of the Secretary, Consumer Product Safety 
    Commission, Room 502, 4330 East-West Highway, Bethesda, Maryland 20814-
    4408, telephone (301) 504-0800. Comments may also be filed by 
    telefacsimile to (301) 504-0127 or by email to cpsc-os@cpsc.gov.

    SUPPLEMENTARY INFORMATION:
    
    A. Background
    
    1. Relevant Statutory and Regulatory Provisions
    
        The Poison Prevention Packaging Act of 1970 (``PPPA''), 15 U.S.C. 
    1471-1476, authorizes the Commission to establish standards for the 
    ``special packaging'' of any household substance if (1) the degree or 
    nature of the hazard to children in the availability of such substance, 
    by reason of its packaging, is such that special packaging is required 
    to protect children from serious personal injury or serious illness 
    resulting from handling, using, or ingesting such substance and (2) the 
    special packaging is technically feasible, practicable, and appropriate 
    for such substance.
        Special packaging, also referred to as ``child-resistant'' (``CR'') 
    packaging, is (1) designed or constructed to be significantly difficult 
    for children under 5 years of age to open or obtain a toxic or harmful 
    amount of the substance contained therein within a reasonable time and 
    (2) not difficult for ``normal adults'' to use properly. 15 U.S.C. 
    1471(4). Household substances for which the Commission may require CR 
    packaging include (among other categories) foods, drugs, or cosmetics 
    that are ``customarily produced or distributed for sale for consumption 
    or use, or customarily stored, by individuals in or about the 
    household.'' 15 U.S.C. 1471(2). The Commission has performance 
    requirements for special packaging. 16 CFR 1700.15, 1700.20.
        Section 4(a) of the PPPA, 15 U.S.C. 1473(a), allows the 
    manufacturer or packer to package a nonprescription product subject to 
    special packaging standards in one size of non-CR packaging only if the 
    manufacturer (or packer) also supplies the substance in CR packages of 
    a popular size, and the non-CR packages bear conspicuous labeling 
    stating: ``This package for households without young children.'' 15 
    U.S.C. 1473(a), 16 CFR 1700.5.
    
    2. Methacrylic Acid
    
        Methacrylic acid (``MAA'') is used as a primer for cleaning, 
    degreasing, dehydrating and etching fingernails before applying 
    artificial nails. Nail products containing MAA are cosmetics under the 
    Food Drug and Cosmetic Act (``FDCA''). According to the FDCA, 
    ``cosmetic'' includes ``articles intended to be rubbed, poured, 
    sprinkled, or sprayed on, introduced into, or otherwise applied to the 
    human body or any part thereof for cleansing, beautifying, promoting 
    attractiveness, or altering appearance.'' 15 U.S.C. 321(i). MAA is also 
    used as a chemical intermediate in making resins, paints, adhesives, 
    paper, polishes, plasticizers and dental fillings. However, the 
    Commission does not believe that these products would be affected by 
    the proposed rule because, in the process of manufacturing these 
    products, the bulk of MAA becomes polymerized and is no longer in the 
    form of the monomer MAA.
        Nail primers are used to help acrylic overlays adhere to the nail 
    surface. Not all nail primers contain MAA. Primers that do contain MAA 
    may have as much as 100 percent MAA, but some may have other 
    ingredients. Of the primers examined by the staff, those that do 
    contain MAA have at least 50 percent MAA. Most of the nail primers that 
    contain MAA are labeled ``For Professional Use Only.'' They are 
    generally distributed through wholesale distributors directly to nail 
    salons and to retail beauty supply stores. Some of these retail stores 
    sell to both professionals and consumers. To obtain samples, CPSC staff 
    visited several beauty supply retail stores, and purchased four nail 
    primers containing MAA. They were packaged in small bottles containing 
    \1/4\ oz. to \1/2\ oz. of primer. All were sold individually packaged, 
    none were CR and all were labeled ``Professional Use Only'' or ``For 
    Professional Use Only.'' The staff obtained an additional primer that 
    was confirmed to contain MAA by mail order purchase. It came in a non-
    CR bottle labeled ``For Professional Use Only.''
        According to industry sources, there may be as many as 50 nail 
    primer suppliers. Approximately 90 percent of nail primers marketed to 
    professionals contain MAA. The Commission is aware of 13 companies that 
    market or have marketed MAA-containing nail primers.
        Based on industry estimates, the CPSC staff estimates annual unit 
    sales of MAA-containing nail primers at about 1.0 to 1.3 million units 
    in \1/4\ oz., \1/2\ oz. and larger sizes. The annual retail value of 
    these units amounts to $4-6.5 million. The wholesale value of these 
    products is about $2.9 to $4.6 million based on a 40 percent mark-up 
    typical of the industry.
        Spokespersons for the industry could not estimate the number of 
    consumers using MAA-containing primers at home. It is clear, however, 
    from the incident data discussed below that these products are used in 
    the household, and children are obtaining access to them. The ability 
    of CPSC staff to purchase these primers at retail stores and by mail 
    also shows that these products are readily available for consumers to 
    purchase and bring home.
    
    B. Toxicity of Methacrylic Acid
    
        MAA is readily absorbed through mucous membranes of the lungs and 
    gastrointestinal (``GI'') tract as well as through the skin. It is 
    rapidly distributed to all major tissues, with the highest 
    concentrations in the liver and kidneys. It is a corrosive, meaning 
    that, when it comes into contact with living tissue, it causes 
    destruction of tissue by chemical action. 15 U.S.C. 1261(i).
        MAA's effects are similar to those of other acids. Dermal burns can 
    destroy the surface of the epithelium and submucosa with damage to 
    blood vessels and connective tissue. Inhaling acid vapors may produce 
    nasal irritation, salivation, conjunctival irritation, difficulty 
    breathing, pleuritic chest pain, and bronchospasm. Ingestion generally 
    produces mild to severe oral and esophageal burns and GI bleeding, 
    perforation, edema, necrosis, stenosis (narrowing of the GI passage) 
    and fistulas (abnormal passages or outpocketings). Other intestinal 
    injuries may also occur. Areas of stricture may develop about 3 weeks 
    after ingestion. Eye exposure may cause pain, swelling, corneal 
    erosions, and blindness.
    
    C. Incident Data
    
        The staff reviewed several sources for information of adverse 
    health effects
    
    [[Page 71802]]
    
    from nail products containing MAA. These sources are published reports 
    in the medical literature, the American Association of Poison Control 
    Centers (``AAPCC''), the FDA Cosmetic Voluntary Registration Program 
    (``CVRP''), and reports from the injury surveillance databases 
    maintained by the Commission.
    
    1. Medical Literature
    
        A recent article in the medical literature analyzed data from the 
    Toxic Exposure Surveillance System (``TESS'') for 1993 through 1995. 
    The American Association of Poison Control Centers (``AAPCC'') collects 
    reports of exposures to toxic chemicals (drugs, household products, 
    poisonous plants, etc.) made to participating poison control centers 
    within the United States in the TESS data base. The TESS data base 
    contains 759 reports of exposures to MAA-containing nail products. Most 
    of the exposures to children less than 6-years-old occurred in the home 
    and involved either ingestion or both dermal contact and ingestion. 
    Children less than 6-years-old accounted for 564 exposures. Two-year-
    old children were most at risk (approximately 330 exposures). 
    Approximately 10 percent of young children suffered moderate to major 
    injuries.1
    ---------------------------------------------------------------------------
    
        \1\ ``Minor symptoms'' means that the patient exhibited some 
    minimal signs or symptoms that resolved rapidly. ``Moderate 
    symptoms'' means the patient exhibited signs or symptoms that were 
    more pronounced, prolonged, or of a systemic nature which usually 
    required some form of treatment (symptoms were not life threatening 
    and there was no residual disability or disfigurement). ``Major 
    symptoms'' means the patient exhibited some symptoms that were life-
    threatening or resulted in disfigurement or residual disability.
    ---------------------------------------------------------------------------
    
        A second recent article reviewed the hazard of nail care products, 
    among them nail primers containing MAA, and reported the medical 
    consequences of ingestion of and/or dermal exposure to primers in two 
    children less than 5-years-old and one adult. In the first case, a 21-
    month-old male accidentally ingested approximately 3-5 ml of a product 
    containing at least 98 percent MAA. The child began drooling, gagging, 
    and vomiting. Physicians at the emergency room (``ER'') of a local 
    hospital observed that the child was in great distress on arrival 30 
    minutes after ingestion. He required endotracheal intubation to 
    maintain the airway and upper GI endoscopy. The upper GI tract, 
    pharynx, and airways showed severe tissue damage. He developed 
    bilateral pneumonia and respiratory distress with stridor (a harsh, 
    high-pitched respiratory sound often associated with acute laryngeal 
    obstruction). He required positive pressure ventilation for 6 days and 
    parenteral nutrition for 15 days. A regular diet was resumed only after 
    he was discharged from the hospital 28 days after he was admitted. 
    Although x-rays of the esophagus and stomach appeared normal one month 
    after discharge, the child experienced intermittent episodes of choking 
    and vomiting. One year later, x-rays confirmed a stricture of the 
    esophagus. Skin burns on the lips, chin, and neck resolved without 
    permanent scarring.
        A 2\1/2\-year-old male spilled approximately 5-7 ml of a product 
    containing at least 98.5 percent MAA onto his face, right arm, and 
    chest. He immediately began screaming. The affected areas were 
    immediately rinsed with water, and he was treated at a nearby hospital 
    20 minutes later. ER personnel noted patchy erythema of the face, 
    chest, right arm, and flank. Blisters developed on his chest. Treatment 
    included rinsing his body and applying silver sulfadiene and aloe to 
    burn areas. All burn areas healed without scarring.
        A 27-year-old female ingested two artificial nail products. The 
    first contained MAA and methylethyl ketone. The second product 
    contained ethyl methacrylate (an ester of MAA), proprietary modifiers, 
    and polymerization accelerators. The woman arrived at the ER 30 minutes 
    after ingestion with symptoms of lethargy and cyanosis (a bluish color 
    of the skin). She also exhibited lesions of the pharynx, mucosal injury 
    in the mouth and pharynx, and ulcerated areas in the upper esophagus. 
    Areas of persistent ulceration in the esophagus were still present 
    after 7 days. She was able to eat a normal diet only after 14 days of 
    hospitalization. These corrosive injuries were due to the MAA as none 
    of the other ingredients in these products were known to be corrosives.
    
    2. CPSC Databases
    
        CPSC has several databases for poison incidents--the National 
    Electronic Injury Surveillance System (``NEISS'') (January 1988--
    September 30, 1998), the Injury and Potential Injury Incident 
    (``IPII'') data base (January 1980--September 30, 1998), the In-Depth 
    Investigations (``INDP'') data base (January 1980--September 30, 1998), 
    and the Children and Poisonings (``CAP'') data base (1978-1987). The 
    staff reviewed these databases for incidents involving nail primers.
        Between 1988 and September 30, 1998, the staff identified 85 cases 
    as exposures to nail products specifically identified as primers or as 
    containing MAA. It is possible that other incidents may have implicated 
    primers and that some of the primers involved in these incidents did 
    not contain MAA.
        NEISS is a stratified probability sample of ER hospitals in the 
    United States and its territories. The staff computed both the national 
    estimates and sampling errors for ER visits by children less than 5 
    years old due to exposures to nail primers. Approximately 2,723 
    estimated ER visits due to exposures to nail primers occurred between 
    January 1988 and September 1998. The lower and upper 95 percent 
    confidence limits of this estimate were 1,756 and 3,690 respectively. 
    Hospitalization was necessary in approximately 10 percent of estimated 
    ER visits (262). The home was the location of exposure in 83 percent of 
    the estimated ER visits (2,272). Primers accounted for 11 of the total 
    15 hospitalizations associated with nail products.
        The INDP files provide additional details on some of these 
    incidents. In one incident, a 2-year-old female spilled a bottle of 
    nail primer containing MAA when she climbed a chair to reach the 
    container placed on a table. On opening the bottle, the child spilled 
    about 1\1/2\ to 2 ounces on her thigh. After trying to rub it off with 
    her hand she then rubbed her face. The child was quickly rinsed off in 
    a shower and taken to the ER. She was treated and released. The child 
    suffered first and second degree burns to her right thigh and both 
    sides of her face from her eyebrows to the bottom of her cheeks.
        A 2-year-old male gained access to an artificial nail kit left on a 
    living room table. The child was about to ingest the bonding agent 
    (primer), possibly MAA, when he spilled about one and one-half ounces 
    on his shirt and around his mouth and nose. He began screaming, turned 
    pale, appeared lethargic, and his eyes were described as glassy. He was 
    immediately taken to the ER where his burns were treated. He remained 
    in the hospital under observation for two nights, was transferred to 
    another hospital for an endoscopy because of difficulty swallowing, and 
    was released after a total of four nights in the hospital.
        A 12-month-old male experienced chemical burns to his hands and 
    mouth from a fingernail primer. The child removed the cap of the primer 
    bottle, and about one ounce of the primer spilled on his hand. The 
    child then rubbed his mouth with his hand and began drooling and 
    frothing. He was immediately taken to the hospital. His chemical burns 
    were treated, and he was released the same day.
    
    [[Page 71803]]
    
    3. AAPCC Data
    
        The staff obtained AAPCC data isolating nail products containing 
    MAA for the years 1996 and 1997. The data include 467 exposures, 
    including 341 poisonings (ingestion, ingestion/dermal), 11 ocular 
    exposures, and 115 dermal exposures to children less than 5-years-old. 
    No deaths were reported. One poisoning with major medical consequences 
    was reported in 1997. This incident is discussed below. There were 32 
    poisoning outcomes coded as moderate (10.7 percent) and 137 poisonings 
    (39.3 percent) coded as having minor outcomes.
        The AAPCC also provided additional information on some exposures 
    reported to, and collected by individual poison control centers. All 
    these exposures involved MAA-containing nail primers. All incidents 
    except one occurred in the child's own residence or in someone else's 
    residence. A summary of the more significant cases from the collection 
    follows below.
        In an incident coded as having a major medical outcome (1997), a 3-
    year-old female experienced burns to her lips and cheeks when she 
    attempted to ingest a nail primer at a beauty salon. She also suffered 
    an anaphylactic reaction, presumably to the MAA in the primer. She 
    remained in a pediatric intensive care unit (ICU) for 2 days. On the 
    third day, she was transferred to a regular bed and her open cheek 
    blisters had healed sufficiently to allow treatment with antibiotic 
    ointment. An endoscopy on day 4 revealed no GI burns, and she was 
    discharged on day 5.
        A 1\1/2\-year-old female experienced burns over half her chest 
    after spilling a bottle of primer on herself. The child required 
    outpatient treatment at a burn center for the next 3 weeks and remained 
    in pain for much of that period. According to the parents, her 
    physician at the Center was considering skin grafts. The burns required 
    approximately 4 weeks to heal.
        A 20-month-old female spilled some primer in the process of 
    attempting to ingest it. Blisters formed on the skin and most of the 
    face within 30 minutes and the child was in evident pain. The pain 
    persisted several days, and the burns did not begin to resolve for 
    another week. The primary physician originally recommended consultation 
    with a plastic surgeon; however, the burns eventually healed without 
    scarring.
    
    4. FDA Database
    
        The FDA's CVRP database contains four reports of injuries from nail 
    primers. One of these reports indicates that a 2-year-old male was 
    brought to the ER after a nail primer splashed in his face and caused 
    burns to the cornea of the eye and the face (1988).
    
    D. Level for Regulation
    
        The Commission is proposing a rule that would require special 
    packaging for household products containing more than 5 percent 
    methacrylic acid.
        At this time, there is no evidence establishing the lowest 
    concentration or amount of MAA capable of causing severe personal 
    injury or illness to young children. The severity of burns to a human 
    from corrosive chemicals is dependent on duration of exposure, site of 
    contact, area of contact, volume and concentration of the product, and 
    the chemical characteristics of the product. These chemical 
    characteristics include pH, physical nature, viscosity, titratable 
    acidity or alkalinity, molarity, oxidation-reduction potential, and 
    complexing affinity for bivalent ions. MAA is a weak organic acid 
    closely resembling acetic acid; in terms of acidity, acetic acid is 
    1.3-fold stronger than MAA when concentration is expressed in percent 
    units. The Commission arrived at a level for regulation based on 
    mutually supportive evidence derived from a report of concentration-
    related skin injury in mice due to MAA, the calculated pH of various 
    concentrations of MAA, and the effects of acetic acid on humans at 
    various concentrations.
        Human evidence does not associate exposures to commercial vinegar 
    (4 to 6 percent acetic acid) with skin burns but suggests these 
    concentrations cause mild skin irritation. The Toxicological Advisory 
    Board (U.S. CPSC, 1982) similarly concluded that 5 percent acetic acid 
    is a weak skin irritant. However, doubling the acetic acid 
    concentration to 10 percent results in classification as a strong skin 
    irritant. Doubling the acetic acid concentration yet again to 20 
    percent requires labeling as a poison under Section 3(b) of the FHSA, 
    16 CFR 1500.129.
        Similarly, concentrations of 4.8 percent MAA cause no irritation 
    (in aqueous solution) or only mild irritation (in acetone solution) to 
    the skin of mice. Doubling that concentration to 9.6 percent in an 
    acetone solution results in epithelial necrosis (tissue destruction) 
    and adverse effects in the dermis of the skin. This degree of injury 
    constitutes a second degree burn to the skin and can best be 
    characterized as severe irritation. Doubling the MAA concentration 
    again to 19.2 percent causes visible destruction to skin epithelium and 
    injury throughout all layers of the skin, including the dermis and 
    submucosal musculature. These skin injuries, if not overtly corrosive, 
    border on corrosive, causing ``visible destruction or irreversible 
    alterations in the tissue at the site of contact'' as defined under the 
    FHSA, 16 CFR 1700.3(c)(3).
        Increasing degrees of injury can also be predicted to the eyes with 
    corresponding changes in MAA concentration (4.8, 9.6, and 19.2 
    percent). In general, acid solutions with a pH of 2.5 or above cause 
    little damage to the eye (the lower the pH, the stronger the acid). For 
    example, the Toxicological Advisory Board classified a solution of 3 
    percent acetic acid, pH 2.53, as a moderate eye irritant. A 4.8 percent 
    solution of MAA has a pH of 2.46, and probably would also be considered 
    a moderate eye irritant, causing reversible inflammatory changes in the 
    eye and its surrounding mucous membranes. Doubling the MAA 
    concentration to 9.6 percent produces a solution with a pH of 2.3. This 
    pH has the potential to produce more serious eye injury with 
    inflammation of the iris and opacity of the cornea. Doubling the MAA 
    concentration yet again to 19.2 percent results in a solution of 2.15, 
    well within the range capable of causing corrosive eye injuries.
        The use of organic solvents such as acetone or ethyl acetate in MAA 
    solutions is likely to increase the degree of injury to eyes, mucous 
    membranes of the GI and respiratory tract, and skin. MAA is soluble in 
    aqueous solutions only to a limited extent (10% maximum). Any 
    concentration of MAA exceeding 9 percent would only dissolve in organic 
    solvents such as acetone that not only cause mild irritation in their 
    own right but exacerbate the toxic effects of MAA itself.
        The actual degree of irritancy or corrosion at 1 to 20 percent 
    concentrations would probably depend on the volume of acid in contact 
    with tissues, the surface area and site affected, and duration of the 
    contact. A concentration of approximately 5 percent MAA does not cause 
    serious injury to mouse skin. It is not likely to be more than a 
    moderate irritant to the eyes of humans, or a mild irritant to the skin 
    of humans. It is equivalent to a 4 percent concentration of acetic acid 
    (about the same as vinegar), that is not associated with serious 
    personal injury or illness in young children. However, concentrations 
    of approximately 10 percent MAA are, at the very least, severe skin 
    irritants in a mouse model and, judging from calculated pH values, are 
    capable of serious eye injury. The weight of the evidence indicates 
    that solutions containing 5 percent MAA
    
    [[Page 71804]]
    
    will not cause serious personal harm or illness in young children. 
    Because the staff is not aware of data defining the precise point 
    between 5 and 10 percent at which injury becomes serious, the staff 
    recommends that child-resistant packaging be required for products 
    containing more than 5 percent MAA to protect children from potential 
    serious injury. The Commission solicits comments on this level.
    
    E. Statutory Considerations
    
    1. Hazard to Children
    
        As noted above, the toxicity data concerning ingestion of MAA 
    demonstrate that MAA can cause serious illness and injury to children. 
    Moreover, it is available to children in the form of nail primers that 
    are accessible in the home. These packages are not CR.
        Pursuant to section 3(a) of the PPPA, 15 U.S.C. 1472(a), the 
    Commission preliminarily finds that the degree and nature of the hazard 
    to children from handling and ingesting household products containing 
    MAA is such that special packaging is required to protect children from 
    serious illness. The Commission bases this finding on the toxic nature 
    of MAA-containing products and their accessibility to children in the 
    home.
    
    2. Technical Feasibility, Practicability, and Appropriateness
    
        In issuing a standard for special packaging under the PPPA, the 
    Commission is required to find that the special packaging is 
    ``technically feasible, practicable, and appropriate.'' 15 U.S.C. 
    1472(a)(2). Technical feasibility may be found when technology exists 
    or can be readily developed and implemented to produce packaging that 
    conforms to the standards. Practicability means that special packaging 
    complying with the standards can utilize modern mass production and 
    assembly line techniques. Packaging is appropriate when complying 
    packaging will adequately protect the integrity of the substance and 
    not interfere with its intended storage or use.
        The staff evaluated the packaging of ten nail primer products. Five 
    of these nail primers contained MAA. Four of the five were packaged in 
    0.25 to 2 ounce brown or tinted glass bottles with 13-20 millimeter 
    (``mm'') non-CR continuous threaded (``CT'') plastic closures. One was 
    in a brown plastic bottle with a non-CR plastic closure. Three of the 
    five packages included a built-in applicator brush, one had a separate 
    applicator brush, and one completely lacked an applicator brush. One 
    primer was packaged in a plastic marker pen with a fiber applicator 
    tip, preventing any substantial flow or spillage of free liquid from 
    the device. The staff is aware of a similar device used for an MAA-
    containing primer sold through a mail order catalog.
        Packaging for MAA-containing nail primers that is senior friendly 
    (``SF'') and CR is technically feasible. There are currently available 
    20 mm CT caps without built-in applicator brushes that are SF and CR. 
    The manufacturer of this cap also manufactures a 28 mm CT closure that 
    is CR and SF and has a built in applicator brush. This manufacturer has 
    indicated to staff that it could develop a 20 mm CR and SF cap with a 
    built-in applicator brush suitable for use with MAA within 6 months to 
    a year. Manufacturers of bottles with smaller finishes (the part of a 
    bottle that receives the cap) may have to change to bottles with 20 mm 
    finishes. However, this should not present a problem since some of the 
    smallest sizes of bottles used for MAA-containing primers (0.25 ounces) 
    already have a 20 mm finish. Manufacturers of MAA-containing primers 
    concerned with spillage have the additional option of using a variety 
    of commercially available restrictive inserts to decrease the inside 
    diameter of the bottle opening in conjunction with CR 20 mm finishes. 
    One manufacturer of MAA-containing primers currently uses such a 
    restriction.
        Special packaging for MAA-containing household products is 
    practicable. CT caps that meet the senior friendly and CR testing 
    requirements have been in mass production for many years. A 20 mm 
    continuous threaded closure that is CR and SF but lacks an insert for a 
    brush is now in mass production. Similarly, a 28 mm continuous threaded 
    closure that is CR and SF and does have an insert for a brush is in 
    mass production. The mass production and assembly line techniques used 
    for the 28 mm CR and SF closure with insert can be adapted to those 
    used for the 20 mm non-CR closure with an insert and brush.
        Special packaging is appropriate when it will protect the integrity 
    of the substance and not interfere with intended storage or use. Nail 
    primers containing MAA are currently packaged in both glass and plastic 
    bottles. Thus, both glass and plastic containers are suitable for MAA-
    containing products. One packaging manufacturer uses identical 
    materials to produce a 28 mm continuous threaded CR and SF closure 
    (equipped with an insert for attaching a brush) and a 20 mm continuous 
    threaded non-CR closure that is currently used for MAA-containing 
    primers and is equipped with an insert and attached brush. Plastic 
    bottle neck restriction devices should also be compatible with MAA 
    since at least one is already in use. Therefore, the same materials 
    used for non-CR packages of MAA-containing products, with or without 
    brushes or inserts, are used or can be used for CR-packages.
    
    3. Other Considerations
    
        In establishing a special packaging standard under the PPPA, the 
    Commission must consider the following:
        a. The reasonableness of the standard;
        b. Available scientific, medical, and engineering data concerning 
    special packaging and concerning childhood accidental ingestions, 
    illness, and injury caused by household substances;
        c. The manufacturing practices of industries affected by the PPPA; 
    and
        d. The nature and use of the household substance. 15 U.S.C. 
    1472(b).
        The Commission has considered these factors with respect to the 
    various determinations made in this notice, and preliminarily finds no 
    reason to conclude that the rule is unreasonable or otherwise 
    inappropriate.
    
    F. Exemption
    
        The Commission is aware of one MAA-containing primer that is 
    packaged in a tube with a fiber applicator tip. The container looks 
    like a plastic marker pen. The fiber strand holds the MAA so that no 
    free liquid flows through the device. An overcap covers the applicator 
    tip. Several manufacturers market this type of device for applying nail 
    primer. Some of these primers contain MAA.
        The Commission believes that MAA-containing primers packaged in 
    this type of device do not pose a risk of serious injury. For this type 
    of package not to pose a risk to children, the Commission believes that 
    two conditions must be met: (1) the absorbent material must hold the 
    MAA so that no free liquid is in the device, and (2) through reasonably 
    foreseeable use the MAA will be released only through the tip of the 
    device. Reasonably foreseeable use would include reasonably foreseeable 
    abuse by children. These conditions are grounded in an existing 
    exemption from FHSA labeling for porous-tip ink-marking devices. 16 CFR 
    1500.83(a)(9).
        Although it might be possible to develop a lug finish CR closure to 
    overcap these devices, based on the design of these devices and 
    available injury information, the Commission
    
    [[Page 71805]]
    
    does not believe that a CR cap is necessary. The volume of MAA 
    available and accessible is extremely small (total amount of material 
    in the devices is reportedly less than 1/2 gram). The only possible 
    route of serious injury would be from direct contact of the felt tip 
    with the eye. The staff has not identified any incidents involving 
    these types of devices. Thus, the Commission proposes to exempt MAA 
    containing primers contained in these marker-like devices if they meet 
    the conditions discussed above.
    
    G. Effective Date
    
        The PPPA provides that no regulation shall take effect sooner than 
    180 days or later than one year from the date such final regulation is 
    issued, except that, for good cause, the Commission may establish an 
    earlier effective date if it determines an earlier date to be in the 
    public interest. 15 U.S.C. 1471n.
        The Commission proposes a one year effective date. Currently, 20 mm 
    CT caps that are CR and senior friendly are available. However, these 
    caps are not available with a built-in applicator brush. Thus, 
    manufacturers will need to make some modifications to provide a CR cap 
    with a built-in applicator. Such closures should be available within 
    one year. This includes time for closure manufacturers to produce the 
    20 mm closures and for product manufacturers to change existing 
    assembly lines to accommodate these closures. Some manufacturers may 
    need to change the bottles currently in use to bottles with 20 mm 
    finishes. A year provides time to produce commercial quantities of the 
    20 mm CR and SF closures, adjust assembly lines to a different bottle 
    size, and conduct testing following the PPPA protocol.
        Thus, the Commission proposes that a rule would take effect 12 
    months after publication of a final rule and would apply to products 
    that are packaged on or after the effective date.
    
    H. Regulatory Flexibility Act Certification
    
        When an agency undertakes a rulemaking proceeding, the Regulatory 
    Flexibility Act, 5 U.S.C. 601 et seq., generally requires the agency to 
    prepare proposed and final regulatory flexibility analyses describing 
    the impact of the rule on small businesses and other small entities. 
    Section 605 of the Act provides that an agency is not required to 
    prepare a regulatory flexibility analysis if the head of an agency 
    certifies that the rule will not have a significant economic impact on 
    a substantial number of small entities.
        The Commission's Directorate for Economic Analysis prepared a 
    preliminary assessment of the impact of a rule to require special 
    packaging for household products containing more than 5 percent 
    methacrylic acid.
        As noted above, the Commission is aware of 13 companies that market 
    nail primers containing MAA. Seven of these may be small businesses. As 
    discussed above, the technology exists to produce CR packaging suitable 
    for use with MAA-containing nail primers. Requiring special packaging 
    for these nail primers may affect many small suppliers. However, the 
    impact on any individual supplier is expected to be small. Generally, 
    incremental costs for CR packaging are low relative to the retail cost 
    of the product. Moreover, these incremental costs would likely be 
    passed on to users (professional nail technicians and consumers who 
    purchase these nail primers). Thus, based on current information, the 
    Commission certifies that the proposed rule is not likely to have a 
    substantial effect on a significant number of small businesses. The 
    Commission requests suppliers, particularly small businesses, to 
    provide information on the impact the proposed rule would have on them.
    
    I. Environmental Considerations
    
        Pursuant to the National Environmental Policy Act, and in 
    accordance with the Council on Environmental Quality regulations and 
    CPSC procedures for environmental review, the Commission has assessed 
    the possible environmental effects associated with the proposed PPPA 
    requirements for MAA-containing products.
        The Commission's regulations state that rules requiring special 
    packaging for consumer products normally have little or no potential 
    for affecting the human environment. 16 CFR 1021.5(c)(3). Nothing in 
    this proposed rule alters that expectation. Therefore, because the rule 
    would have no adverse effect on the environment, neither an 
    environmental assessment nor an environmental impact statement is 
    required.
    
    J. Executive Orders
    
        According to Executive Order 12988 (February 5, 1996), agencies 
    must state in clear language the preemptive effect, if any, of new 
    regulations.
        The PPPA provides that, generally, when a special packaging 
    standard issued under the PPPA is in effect, ``no State or political 
    subdivision thereof shall have any authority either to establish or 
    continue in effect, with respect to such household substance, any 
    standard for special packaging (and any exemption therefrom and 
    requirement related thereto) which is not identical to the [PPPA] 
    standard.'' 15 U.S.C. 1476(a). Upon application to the Commission, a 
    State or local standard may be excepted from this preemptive effect if 
    the State or local standard (1) provides a higher degree of protection 
    from the risk of injury or illness than the PPPA standard and (2) does 
    not unduly burden interstate commerce. In addition, the Federal 
    government, or a State or local government, may establish and continue 
    in effect a non-identical special packaging requirement that provides a 
    higher degree of protection than the PPPA requirement for a household 
    substance for the Federal, State or local government's own use. 15 
    U.S.C. 1476(b).
        Thus, with the exceptions noted above, the proposed rule requiring 
    CR packaging for household products containing more than 5 percent MAA 
    would preempt non-identical state or local special packaging standards 
    for such MAA containing products.
        In accordance with Executive Order 12612 (October 26, 1987), the 
    Commission certifies that the proposed rule does not have sufficient 
    implications for federalism to warrant a Federalism Assessment.
    
    List of Subjects in 16 CFR Part 1700
    
        Consumer protection, Cosmetics, Infants and children, Packaging and 
    containers, Poison prevention, Toxic substances.
    
        For the reasons given above, the Commission proposes to amend 16 
    CFR part 1700 as follows:
    
    PART 1700--[AMENDED]
    
        1. The authority citation for part 1700 continues to read as 
    follows:
    
        Authority: Pub. L. 91-601, secs. 1-9, 84 Stat. 1670-74, 15 
    U.S.C. 1471-76. Secs 1700.1 and 1700.14 also issued under Pub. L. 
    92-573, sec. 30(a), 88 Stat. 1231. 15 U.S.C. 2079(a).
    
        2. Section 1700.14 is amended by republishing the introductory text 
    of paragraph (a) and adding new paragraph (a)(29) to read as follows:
    
    
    Sec. 1700.14  Substances requiring special packaging.
    
        (a) Substances. The Commission has determined that the degree or 
    nature of the hazard to children in the availability of the following 
    substances, by reason of their packaging, is such that special 
    packaging meeting the requirements of Sec. 1700.20(a) is required to 
    protect children from serious personal injury or
    
    [[Page 71806]]
    
    serious illness resulting from handling, using, or ingesting such 
    substances, and the special packaging herein required is technically 
    feasible, practicable, and appropriate for these substances:
    * * * * *
        (29) Methacrylic acid. Except as provided in the following 
    sentence, liquid household products containing more than 5 percent 
    methacrylic acid (weight-to-volume) in a single retail package shall be 
    packaged in accordance with the provisions of Sec. 1700.15(a),(b) and 
    (c). Methacrylic acid products applied by an absorbent material 
    contained inside a dispenser (such as a pen-like marker) are exempt 
    from this requirement provided that: the methacrylic acid is contained 
    by the absorbent material so that no free liquid is within the device; 
    and under any reasonably foreseeable conditions of use the methacrylic 
    acid will emerge only through the tip of the device.
