Indirect Food Additives: Adjuvants, Production Aids, and
Sanitizers
AGENCY: Food and Drug Administration, HHS.
ACTION: Final rule.

[[Page 31396]]
SUMMARY: The Food and Drug Administration (FDA) is amending the food
additive regulations to provide for the safe use of an aqueous solution
of chlorine dioxide and related oxychloro species, generated by
acidification of an aqueous solution of sodium chlorite with a solution
of sodium gluconate, citric acid, phosphoric acid, and sodium mono- and
didodecylphenoxybenzenedisulfonate, as a sanitizing solution to be used
on food-processing equipment and utensils, including dairy-processing
equipment. This action responds to a petition filed by Rio Linda
Chemical Co.
DATES: Effective June 20, 1996 written objections and requests for a
hearing by July 22, 1996. The Director of the Office of the Federal
Register approves the incorporation by reference in accordance with 5
U.S.C. 552(a) and 1 CFR part 51 of a publication listed in
Sec. 178.1010 (21 CFR 178.1010), effective June 20, 1996.
ADDRESSES: Submit written objections to the Dockets Management Branch
(HFA-305), Food and Drug Administration, 12420 Parklawn Dr., rm. 1-23,
Rockville, MD 20857.
FOR FURTHER INFORMATION CONTACT: Mitchell Cheeseman, Center for Food
Safety and Applied Nutrition (HFS-217), Food and Drug Administration,

SUPPLEMENTARY INFORMATION: In a notice published in the Federal
Register of September 22, 1992 (57 FR 43741), FDA announced that a food
additive petition (FAP 2B4334) had been filed by Rio Linda Chemical
Co., c/o 1414 Fenwick Lane, Silver Spring, MD 20910. The petition
proposed that the food additive regulations be amended in Sec. 178.1010
Sanitizing solutions (21 CFR 178.1010) to provide for the safe use of
an aqueous solution of chlorine dioxide and related oxychloro species,
generated by acidification of an aqueous solution of sodium chlorite
with sodium gluconate, citric acid, phosphoric acid, and sodium
alkylphenoxybenzenedisulfonate, as a sanitizing solution to be used on
food-contact surfaces, food-processing equipment, and utensils. Based
on information in the food additive petition, FDA has determined that a
more specific and therefore more appropriate name for the form of
sodium alkylphenoxybenzenedisulfonate used to generate the subject
sanitizing solution is sodium mono- and
didodecylphenoxybenzenedisulfonate. This more specific name will be
used throughout the remainder of this document.
I. Safety and Functional Effect of Petitioned Use of the Additive
-Sanitizing solutions are mixtures of chemicals that function
together to sanitize food-contact surfaces and are regulated as such.
Each listed component in a sanitizing solution has a functional effect,
and the agency evaluates the data submitted in support of the efficacy
of the entire sanitizing solution. The subject sanitizing solution is
an aqueous solution of chlorine dioxide and related oxychloro species,
generated by acidification of an aqueous solution of sodium chlorite
with a solution of sodium gluconate, citric acid, phosphoric acid, and
sodium mono- and didodecylphenoxybenzenedisulfonate. The functions of
these components, and the basis for FDA's determination of the safety
of these components in the subject sanitizer, are described below.
A. Chlorine Dioxide
Chlorine dioxide functions as an antimicrobial agent in the
subject sanitizing solution. Chlorine dioxide is regulated for use in
sanitizing solutions under Sec. 178.1010(b)(34) and is regulated for
use as an antimicrobial agent in water used in poultry processing under
21 CFR 173.69. On the basis of the data submitted in support of the
already-regulated uses of chlorine dioxide, the data contained in the
food additive petition submitted in support of this sanitizing
solution, and studies in the scientific literature, FDA finds that the
use of chlorine dioxide in the subject sanitizing solution is safe
(Ref. 1).
B. Sodium Gluconate
-Sodium gluconate functions as a sequestering agent in the subject
sanitizing solution. Sodium gluconate is listed as GRAS for use in food
as a sequestering agent under 21 CFR 182.6757. In addition, FDA
regulations permit the addition to a sanitizing solution of any
substance that is GRAS for use in food (Sec. 178.1010(b)). On the basis
of the data supporting the GRAS status of sodium gluconate, FDA finds
that the use of sodium gluconate in the subject sanitizing solution is
safe (Ref. 1).
C. Citric Acid
Citric acid functions as a sequestering agent in the subject
sanitizing solution. Citric acid is affirmed as GRAS for use in food
under 21 CFR 184.1033. In addition, as stated in the previous
paragraph, FDA regulations permit the addition to a sanitizing solution
of any substance that is GRAS for use in food. On the basis of the data
supporting the GRAS status of citric acid, FDA finds that the use of
citric acid in the subject sanitizing solution is safe (Ref. 1).
D. Phosphoric Acid
-Phosphoric acid functions as an activator in the subject
sanitizing solution. Phosphoric acid is listed as GRAS for use in food
under 21 CFR 182.1073. In addition, FDA regulations permit the addition
to a sanitizing solution of any substance that is GRAS for use in food.
On the basis of the data supporting the GRAS status of phosphoric acid,
FDA finds that the use of phosphoric acid in the subject sanitizing
solution is safe (Ref. 1).
E. Sodium Mono- and Didodecylphenoxybenzenedisulfonate
-Sodium mono- and didodecylphenoxybenzenedisulfonate functions as a
surfactant in the subject sanitizing solution. Sodium mono- and
didodecylphenoxybenzenedisulfonate is regulated for use as an
emulsifier and surface active agent in the manufacture of food-contact
materials under the listing for sodium mono- and
dialkylphenoxybenzenedisulfonate in 21 CFR 178.3400(c). On the basis of
the data submitted in support of the already-regulated use of sodium
mono- and didodecylphenoxybenzenedisulfonate and the data contained in
the food additive petition submitted in support of this sanitizing
solution, FDA finds that the use of sodium mono- and
didodecylphenoxybenzenedisulfonate in the subject sanitizing solution
is safe (Ref. 1).
F. Conclusion on Safety
-As discussed above, FDA has evaluated data on the antimicrobial
efficacy of the entire sanitizing solution and data in the petition and
other relevant materials on the safety of each of the components of the
sanitizing solution. On the basis of this evaluation, the agency
concludes that these data and materials establish the safety and
efficacy of the additive for use as a sanitizing solution on food-
processing equipment and utensils including dairy-processing equipment,
and that the regulations should be amended in Sec. 178.1010 as set
forth below.
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 are available for inspection at the
Center for Food Safety and Applied Nutrition by appointment with the
information contact person listed above. As provided in 21 CFR
171.1(h), the agency will delete from the documents any materials that
are not
[[Page 31397]]
available for public disclosure before making the documents available
for inspection.
II. Environmental Impact
The agency has carefully considered the potential environmental
effects of this action. FDA has concluded that the action will not have
a significant impact on the human environment, and that an
environmental impact statement is not required. The agency's finding of
no significant impact and the evidence supporting that finding,
contained in an environmental assessment, may be seen in the Dockets
Management Branch (address above) between 9 a.m. and 4 p.m., Monday
through Friday.
III. Reference
The following reference has been placed on display in the Dockets
Management Branch (address above) and may be seen by interested persons
