SUPPLEMENTARY INFORMATION:
I. Background
In a notice published in the Federal Register of April 8, 2010 (75
FR 17928), FDA announced that Nisso America Inc., 45 Broadway, Suite
2120, New York, NY 10006, filed a food additive petition (FAP 0A4780).
The petition proposed to amend the food additive regulations in Sec.
172.870 (21 CFR 172.870), by lowering the minimum permitted viscosity
of hydroxypropyl cellulose (HPC) identified in Sec. 172.870(a)(1) from
145 cPs to 10 cPs and to permit its use as a binder in dietary
supplements.
Section 172.870 includes both high-substituted HPC, which contains
not more than 4.6 hydroxypropyl groups per anhydroglucose unit (Sec.
172.870(a)(1)), and low-substituted HPC, which contains on average 0.1
to 0.4 hydroxypropyl groups per anhydroglucose unit (Sec.
172.870(a)(2)). High-substituted HPC can be used, in accordance with
good manufacturing practice, as an emulsifier, film former, protective
colloid, stabilizer, suspending agent and thickener (Sec.
172.870(b)(1)). Low-substituted HPC can be used, in accordance with
good manufacturing practice, as a binder and disintegrator in tablets
or wafers containing dietary supplements (Sec. 172.870(b)(2)). It is
the high-substituted HPC regulated under Sec. 172.870(a)(1) and (b)(1)
that is the subject of this petition.
II. Evaluation of Safety
Under the general safety standard in section 409 of the Federal
Food, Drug, and Cosmetic Act (the FD&C Act) (21 U.S.C. 348), a food
additive cannot be approved for a particular use unless a fair
evaluation of the data available to FDA establishes that the additive
is safe for that use. FDA's food additive regulations (21 CFR 170.3(i))
define safe as ``a reasonable certainty in the minds of competent
scientists that the substance is not harmful under the intended
conditions of use.'' To establish with reasonable certainty that
[[Page 41688]]
a food additive is not harmful under its intended conditions of use,
FDA considers the estimated human dietary intake of the additive, the
additive's toxicological data, and other relevant information (such as
published literature) available to the Agency.
Both high-substituted HPC (the subject of this petition) and low-
substituted HPC are forms of cellulose and cellulose derivatives. The
safety of cellulose and cellulose derivatives has been studied
extensively in animals and humans. These studies show that cellulose
and cellulose derivatives pass unchanged through the gastrointestinal
tract and can be quickly detected in the feces of test animals and
humans when consumed, confirming that the consumption of cellulose and
cellulose derivatives at the proposed viscosity and use level will not
result in toxicity. The Joint Food and Agriculture Organization and the
World Health Organization (FAO/WHO) Expert Committee for Food Additives
(JECFA) has evaluated the food uses of modified celluloses, including
HPC, and has concluded that, as a group, modified celluloses are of
very low toxicity at the levels of intake necessary to achieve the
desired effect and do not pose a hazard to health (Ref. 1). Viscosity
is not specified by the JECFA as a factor related to the safety of
these additives.
Although there is no available safety testing directly on HPC with
a viscosity of < 145 cPs, there have been numerous studies on the
viscosity related safety effect for other modified celluloses. Most of
the safety studies we reviewed analyzed the use of cellulose and
cellulose derivatives. All of these studies support the assertion that
there is no safety effect arising from a change in viscosity. Because
high-substituted HPC with a minimum viscosity of 10 cPs is not expected
to have significantly different biological properties than those
cellulose and cellulose derivatives which have been studied, or the
high and low-substituted HPC currently permitted under Sec. 172.870,
FDA concludes that the proposed use of high-substituted HPC with a
minimum viscosity of 10 cPs is safe.
Lastly, because high-substituted HPC with a minimum viscosity of 10
cPs is intended to be used for the same purposes as are currently
permitted for either high and low-substituted HPC, including as a
binder in dietary supplements, FDA concludes that the proposed changes
to Sec. 172.870 will not result in an increase in the combined overall
daily intake of high-substituted and low-substituted HPC. Thus,
permitting the use of high-substituted HPC with a minimum viscosity of
10 cPs for use as a binder in dietary supplements will not result in an
increased intake or harm to human health under the established
conditions of use.
III. Conclusion
FDA reviewed data in the petition and other available relevant
material to evaluate the safety of the petitioned use of high-
substituted HPC with a minimum viscosity of 10 cPs as an emulsifier,
film former, protective colloid, stabilizer, suspending agent, or
thickener in food, and as a binder in dietary supplements. Based on
this information, FDA concludes that the proposed use of the additive
is safe and will achieve its intended technical effect under the
proposed conditions of use. Therefore, the regulations in 21 CFR part
172 should be amended as set forth in this document.
IV. Public Disclosure
In accordance with Sec. 171.1(h) (21 CFR 171.1(h)), the petition
and the documents that FDA considered and relied upon in reaching its
decision to approve the petition will be made available for inspection
at the Center for Food Safety and Applied Nutrition by appointment with
the information contact person (see FOR FURTHER INFORMATION CONTACT).
As provided in Sec. 171.1(h), the Agency will delete from the
documents any materials that are not available for public disclosure
before making the documents available for inspection.
V. Environmental Impact
The Agency has previously considered the environmental effects of
this rule as announced in the notice of filing for FAP 0A4780 (75 FR
17928). No new information or comments have been received that would
affect the Agency's previous determination that there is no significant
impact on the human environment and that an environmental impact
statement is not required.
VI. Paperwork Reduction Act of 1995
This final rule contains no collection of information. Therefore,
clearance by the Office of Management and Budget under the Paperwork
Reduction Act of 1995 is not required.
VII. Objections
Any person who will be adversely affected by this regulation may
file with the Division of Dockets Management (see ADDRESSES) either
electronic or written objections. Each objection shall be separately
numbered, and each numbered objection shall specify with particularity
the provisions of the regulation to which objection is made and the
grounds for the objection. Each numbered objection on which a hearing
is requested shall specifically so state. Failure to request a hearing
for any particular objection shall constitute a waiver of the right to
a hearing on that objection. Each numbered objection for which a
hearing is requested shall include a detailed description and analysis
of the specific factual information intended to be presented in support
of the objection in the event that a hearing is held. Failure to
include such a description and analysis for any particular objection
shall constitute a waiver of the right to a hearing on the objection.
It is only necessary to send one set of documents. It is no longer
necessary to send three copies of all documents. Identify documents
with the docket number found in brackets in the heading of this
document. Any objections received in response to the regulation may be
seen in the Division of Dockets Management between 9 a.m. and 4 p.m.,
Monday through Friday.
VIII. Section 301(ll) of the Federal Food, Drug, and Cosmetic Act
FDA's review of this petition was limited to section 409 of FD&C
Act. This final rule is not a statement regarding compliance with other
sections of the FD&C Act. For example, the Food and Drug Administration
Amendments Act of 2007, which was signed into law on September 27,
2007, amended the FD&C Act to, among other things, add section 301(ll)
(21 U.S.C. 331(ll)). Section 301(ll) of the FD&C Act prohibits the
introduction or delivery for introduction into interstate commerce of
any food that contains a drug approved under section 505 of the FD&C
Act (21 U.S.C. 355), a biological product licensed under section 351 of
the Public Health Service Act (42 U.S.C. 262), or a drug or biological
product for which substantial clinical investigations have been
instituted and their existence has been made public, unless one of the
exceptions in section 301(ll)(1) to (ll)(4) applies. In our review of
this petition, FDA did not consider whether section 301(ll) of the FD&C
Act or any of its exemptions apply to food containing this additive.
Accordingly, this final rule should not be construed to be a statement
that a food containing this additive, if introduced or delivered for
introduction into interstate commerce, would not violate section
301(ll) of the FD&C Act. Furthermore, this language is included in all
food additive final rules and therefore should not be construed to be a
statement of the likelihood that section 301(ll) of the FD&C Act
applies.
