[Docket No. 80N-0196]
Japan Wax; Affirmation of GRAS Status as an Indirect Human Food
Ingredient; Reproposed Rule
AGENCY: Food and Drug Administration, HHS.
ACTION: Reproposed rule.
-----------------------------------------------------------------------
SUMMARY: The Food and Drug Administration (FDA) is proposing to affirm
Japan wax as generally recognized as safe (GRAS) as an indirect human
food ingredient for use as a constituent of cotton and cotton fabrics
used in dry food packaging. In light of this action, the agency is
withdrawing its July 9, 1982 (47 FR 29965), proposal to delete this use
of Japan wax from GRAS status as an indirect human food ingredient
(hereinafter referred to as the July 1982 proposal). This action
results from FDA's review of all available information on Japan wax,
including documents located in food additive extension file no. 393
(FAX 393) supporting its history of common use in food contact cotton
bags and an acute oral toxicity study on mice that has been obtained
since the publication of the July 1982 proposal to delete this use from
the GRAS list.
DATES: Written comments by August 15, 1995.
ADDRESSES: Submit written comments to the Dockets Management Branch
(HFA-305), Food and Drug Administration, rm. 1-23, 12420 Parklawn Dr.,
Rockville, MD 20857.

SUPPLEMENTARY INFORMATION:
I. Background
FDA has been conducting a comprehensive review of human food
ingredients classified as GRAS or subject to a prior sanction. Under
this review, the agency has evaluated the safety of Japan wax, and FDA
has reconsidered its July 1982 proposal to remove Japan wax from the
GRAS list.
Japan wax (CAS Reg. No. 8001-39-6), also known as Japan tallow or
sumac wax, is a pale yellow vegetable tallow, containing glycerides of
the C19-C23 dibasic acids and a high content of tripalmitin.
It is prepared from the mesocarp by hot pressing of immature fruits of
the oriental sumac, Rhus succedanea (Japan, Taiwan and Indo-China), R.
vernicifera (Japan), and R. trichocarpa (China, Indo-China, India, and
Japan).
Japan wax is listed in Sec. 182.70 (21 CFR 182.70) as GRAS for use
as a substance migrating to food from cotton and cotton fabrics used in
dry food packaging based upon a final rule published in the Federal
Register of June 10, 1961 (26 FR 5224). This final rule was the
original GRAS listing for substances migrating to food from cotton and
cotton fabrics used in dry food packaging and included only substances
in common use prior to that time. Japan wax was one of the substances
identified to FDA, in response to the 1958 Food Additives Amendment to
the Federal Food, Drug, and Cosmetic Act (the act), by the National
Cotton Council of America as being in use prior to 1958 in food contact
articles (cotton bags) (Ref. 1). One member of the Council, Seydel-
Woolley & Co., had reported using Japan wax for the sizing of cloth
used for food bags or similar uses (Ref. 2). Japan wax had been in use
in textile finishing for many years (Refs. 3 and 4). Japan wax is also
listed in Sec. 73.1(b)(2) (21 CFR 73.1(b)(2)) for use in diluents in
color additive mixtures for coloring shell eggs, in Sec. 175.105 (21
CFR 175.105) for use as a component of adhesives, in Sec. 175.350
(d)(3) (21 CFR 175.350 (d)(3)) for use as an optional substance in
vinyl acetate/crotonic acid copolymer, and in Sec. 176.170 (a)(5) (21
CFR 176.170 (a)(5)) for use as a component of paper and paperboard in
contact with aqueous and fatty foods. This action does not affect these
regulated food additive or color additive uses of Japan wax.
The July 1982 proposal stated that insufficient safety data existed
to affirm the GRAS status of the ingredient for indirect human food
use. The July 1982 proposal also stated that the proposed action would
not affect the regulated uses of Japan wax as a food additive and as a
color additive diluent. The July 1982 proposal was published in
accordance with the announced FDA review of the safety of GRAS and
prior-sanctioned food ingredients.
The basis for the July 1982 proposal was the evaluation of the 1975
final report of the Select Committee on GRAS Substances (the Select
Committee), composed of qualified scientists chosen by the Life
Sciences Research Office of the Federation of American Societies for
Experimental Biology (LSRO/FASEB). This report was one of a series
concerning the health aspects of using GRAS and prior-sanctioned food
substances as food ingredients, done by LSRO/FASEB under contract with
FDA. FDA requested these reviews of the safety of substances that were
listed as GRAS only on the basis of their common use in food prior to
1958. The Select Committee's report, entitled ``Evaluation of the
Health Aspects of Japan Wax as a Substance Migrating to Food from
Cotton and Cotton Fabrics Used in Dry Food Packaging'' (Ref. 5),
included the results of an in vitro mutagenic evaluation of Japan wax
[[Page 28556]] using Saccharomyces cerevisiae, strain D4, and
Salmonella typhimurium, strains TA-1536, TA-1537, and TA-1538, with and
without metabolic activation (Ref. 6). In these assays, Japan wax
exhibited no mutagenic activity. The Select Committee's report,
however, concluded that there were insufficient data upon which to
evaluate the safety of Japan wax for use as a substance migrating to
food from cotton and cotton fabrics used in dry food packaging.
Although FDA proposed to remove this use from the GRAS list, the July
1982 proposal further stated that if information was subsequently
obtained to support the safe use of Japan wax in cotton and cotton
fabrics for use in dry food packaging, FDA would reconsider the July
1982 proposal.
In the Federal Register of August 28, 1991 (56 FR 42668)
(hereinafter referred to as the August 1991 notice of intent), FDA
published a notice of intent to review all of the proposed rules that
the agency had published in the Federal Register on or before December
31, 1985, but for which no final rule or notice of withdrawal had been
published. The agency then tentatively concluded that 115 of these pre-
1986 proposals should be withdrawn, including the proposed deletion of
Japan wax from GRAS status, and invited comments on FDA's intent to
withdraw these proposals. No comments were received concerning Japan
wax.
After due consideration of all comments received in response to the
August 1991 notice of intent, FDA announced in the Federal Register of
December 30, 1991 (56 FR 67440), that it was withdrawing 89 proposed
rules that were published in the Federal Register on or before December
31, 1985, and was deferring a decision on withdrawal of 26 proposed
rules. The agency also announced that it had, on its own initiative,
further reviewed its proposal to withdraw the proposed deletion from
GRAS status of Japan wax, published in the July 1982 proposal, and had
decided to defer the withdrawal of this proposal.
II. Safety
Since the publication of the Select Committee's report, FDA has
found evidence that bears on the safe use of Japan wax in the treatment
of cotton fabric used for dry food packaging. The agency has received
and considered an acute oral toxicity study in which mice were given 15
grams per kilogram body weight doses of Japan wax for 5 days (Ref. 7).
No mortality was observed and no adverse effects were noted in this
study. The agency has also conducted a review of the scientific
literature since the 1975 final report of the Select Committee and has
found no information that would cause any safety concerns about this
use of Japan wax.
After obtaining the acute oral toxicity study, FDA reexamined the
documents in its possession and other evidence supporting the history
of common use of Japan wax in cotton fabrics used in dry food
packaging. The agency found letters from a textile manufacturer and
from the National Cotton Council of America in a food additive
extension file (FAX 393), identifying Japan wax as one of the
substances being used in the sizing of cloth used for food bags prior
to 1958 (Refs. 1 and 2). FAX files contain the administrative record of
industry requests for continued use of food ingredients, pending FDA's
publication of regulations as required by the 1958 Food Additives
Amendment to the act. The requests were made in the period immediately
following the passage of the Food Additives Amendment.
As provided for under Sec. 170.30(b) (21 CFR 170.30(b)), FDA has
tentatively determined that the history of safe use of Japan wax since
before 1958 provides an adequate basis upon which to affirm that the
use of Japan wax in cotton and cotton fabrics used in dry food
packaging is GRAS. The GRAS status of this use is corroborated by the
acute study and by the in vitro mutagenic evaluation. Therefore, in
accordance with the provisions of Secs. 170.30 and 170.35 (21 CFR
170.35), the agency is proposing to affirm that Japan wax is GRAS for
use as a constituent of cotton and cotton fabrics used in dry food
packaging, on the basis of its common use in food prior to 1958,
corroborated by further evidence of its safety obtained since the
Select Committee's evaluation.
III. Economic Impact
FDA has examined the impacts of the proposed rule under Executive
Order 12866 and the Regulatory Flexibility Act (Pub. L. 96-354).
Executive Order 12866 directs agencies to assess all costs and benefits
of available regulatory alternatives and, when regulation is necessary,
to select regulatory approaches that maximize net benefits (including
potential economic, environmental, public health and safety, and other
advantages; distributive impacts; and equity). The agency believes that
this proposed rule is consistent with the regulatory philosophy and
principles identified in the Executive Order. In addition, the proposed
rule is not a significant regulatory action as defined by the Executive
Order and so is not subject to review under the Executive Order.
The Regulatory Flexibility Act requires agencies to analyze
regulatory options that would minimize any significant impact of a rule
on small entities. Because the proposed rule would not prohibit any
current activity, the agency certifies that the proposed rule will not
have a significant economic impact on a substantial number of small
entities. Therefore, under the Regulatory Flexibility Act, no further
analysis is required.
IV. Environmental Impact
FDA has determined under 21 CFR 25.24(b)(7) that this action is of
a type that does not individually or cumulatively have a significant
effect on the human environment. Therefore, neither an environmental
assessment nor an environmental impact statement is required.
V. Prior Sanctions
The agency is unaware of any prior sanction for the use of this
ingredient in foods under conditions different from those identified in
this document. Any person who intends to assert or rely on such a
sanction shall submit proof of its existence in response to this
proposal. The action proposed above will constitute a determination
that excluded uses would result in adulteration of the food in
violation of section 402 of the act (21 U.S.C. 342), and the failure of
any person to come forward with proof of such an applicable prior
sanction in response to this proposal constitutes a waiver of their
right to assert or rely on it later. Should any person submit proof of
the existence of a prior sanction, the agency hereby proposes to
recognize such use by issuing an appropriate final rule under part 181
(21 CFR part 181) or affirming it as GRAS under part 184 or 186 (21 CFR
part 184 or 186), as appropriate.
VI. Comments

Dockets Management Branch (address above) written comments regarding
this proposal. Two copies of any comments are to be submitted, except
that individuals may submit one copy. Comments are to be identified

Therefore, under the Federal Food, Drug, and Cosmetic Act and under
authority delegated to the Commissioner of Food and Drugs and
redelegated to the Director, Center for Food Safety and Applied
Nutrition, the proposed rule that published in the Federal Register of
July 9, 1982 (47 FR 29965) is withdrawn; and it is proposed that 21 CFR
parts 182 and 186 be amended to read as follows:
PART 182--SUBSTANCES GENERALLY RECOGNIZED AS SAFE
1. The authority citation for 21 CFR part 182 continues to read as
follows:
Authority: Secs. 201, 402, 409, 701 of the Federal Food, Drug,
and Cosmetic Act (21 U.S.C. 321, 342, 348, 371).
Sec. 182.70 [Amended]
2. Section 182.70 Substances migrating from cotton and cotton
fabrics used in dry food packaging is amended by removing the entry for
``Japan wax.''
PART 186--INDIRECT FOOD SUBSTANCES AFFIRMED AS GENERALLY RECOGNIZED
AS SAFE
3. The authority citation for 21 CFR part 186 continues to read as
follows:
Authority: Secs. 201, 402, 409, 701 of the Federal Food, Drug,
and Cosmetic Act (21 U.S.C. 321, 342, 348, 371).
4. New Sec. 186.1555 is added to subpart B to read as follows:
Sec. 186.1555 Japan wax.
(a) Japan wax (CAS Reg. No. 8001-39-6), also known as Japan tallow
or sumac wax, is a pale yellow vegetable tallow, containing glycerides
of the C19-C23 dibasic acids and a high content of
tripalmitin. It is prepared from the mesocarp by hot pressing of
immature fruits of the oriental sumac, Rhus succedanea (Japan, Taiwan,
and Indo-China), R. vernicifera (Japan), and R. trichocarpa (China,
Indo-China, India, and Japan). Japan wax is soluble in hot alcohol,
benzene, and naphtha, and insoluble in water and in cold alcohol.
(b) In accordance with paragraph (b)(1) of this section, the
ingredient is used as an indirect human food ingredient with no
limitation other than current good manufacturing practice. The
affirmation of this ingredient as generally recognized as safe (GRAS)
as an indirect human food ingredient is based on the following current
good manufacturing practice conditions of use:
(1) The ingredient is used as a constituent of cotton and cotton
fabrics used for dry food packaging.
(2) The ingredient is used at levels not to exceed current good
manufacturing practice.
(c) Prior sanctions for this ingredient different from the uses
established in this section do not exist or have been waived.
