PART 181--PRIOR-SANCTIONED FOOD INGREDIENTS--Table of Contents
 
                      Subpart A--General Provisions
 
Sec. 181.1  General.
 
 
    (a) An ingredient whose use in food or food packaging is subject to 
a prior sanction or approval within the meaning of section 201(s)(4) of 
the Act is exempt from classification as a food additive. The 
Commissioner will publish in this part all known prior sanctions. Any 
interested person may submit to the Commissioner a request for 
publication of a prior sanction, supported by
 
[[Page 451]]
 
evidence to show that it falls within section 201(s)(4) of the Act.
    (b) Based upon scientific data or information that shows that use of 
a prior-sanctioned food ingredient may be injurious to health, and thus 
in violation of section 402 of the Act, the Commissioner will establish 
or amend an applicable prior sanction regulation to impose whatever 
limitations or conditions are necessary for the safe use of the 
ingredient, or to prohibit use of the ingredient.
    (c) Where appropriate, an emergency action level may be issued for a 
prior-sanctioned substance, pending the issuance of a final regulation 
in accordance with paragraph (b) of this section. Such an action level 
shall be issued pursuant to section 402(a) of the Act to identify, based 
upon available data, conditions of use of the substance that may be 
injurious to health. Such an action level shall be issued in a notice 
published in the Federal Register and shall be followed as soon as 
practicable by a proposed regulation in accordance with paragraph (b) of 
this section. Where the available data demonstrate that the substance 
may be injurious at any level, use of the substance may be prohibited. 
The identification of a prohibited substance may be made in part 189 of 
this chapter when appropriate.

PART 181--PRIOR-SANCTIONED FOOD INGREDIENTS--Table of Contents
 
                      Subpart A--General Provisions
 
Sec. 181.5  Prior sanctions.
 
    (a) A prior sanction shall exist only for a specific use(s) of a 
substance in food, i.e., the level(s), condition(s), product(s), etc., 
for which there was explicit approval by the Food and Drug 
Administration or the United States Department of Agriculture prior to 
September 6, 1958.
    (b) The existence of a prior sanction exempts the sanctioned use(s) 
from the food additive provisions of the Act but not from the other 
adulteration or the misbranding provisions of the Act.
    (c) All known prior sanctions shall be the subject of a regulation 
published in this part. Any such regulation is subject to amendment to 
impose whatever limitation(s) or condition(s) may be necessary for the 
safe use of the ingredient, or revocation to prohibit use of the 
ingredient, in order to prevent the adulteration of food in violation of 
section 402 of the Act.
    (d) In proposing, after a general evaluation of use of an 
ingredient, regulations affirming the GRAS status of substances added 
directly to human food in part 184 of this chapter or substances in 
food-contact surfaces in part 186 of this chapter, or establishing a 
food additive regulation for substances added directly to human food in 
parts 172 and 173 of this chapter or food additives in food-contact 
surfaces in parts 174, 175, 176, 177, 178 and Sec. 179.45 of this 
chapter, the Commissioner shall, if he is aware of any prior sanction 
for use of the ingredient under conditions different from those proposed 
in the regulation, concurrently propose a separate regulation covering 
such use of the ingredient under this part. If the Commissioner is 
unaware of any such applicable prior sanction, the proposed regulation 
will so state and will require any person who intends to assert or rely 
on such sanction to submit proof of its existence. Any food additive or 
GRAS regulation promulgated after a general evaluation of use of an 
ingredient constitutes a determination that excluded uses would result 
in adulteration of the food in violation of section 402 of the Act, and 
the failure of any person to come forward with proof of such an 
applicable prior sanction in response to a proposal will constitute a 
waiver of the right to assert or rely on such sanction at any later 
time. The notice will also constitute a proposal to establish a 
regulation under this part, incorporating the same provisions, in the 
event that such a regulation is determined to be appropriate as a result 
of submission of proof of such an applicable prior sanction in response 
to the proposal.

Sec. 181.22  Certain substances employed in the manufacture of food-packaging materials.
 
 
    Prior to the enactment of the food additives amendment to the 
Federal Food, Drug, and Cosmetic Act, sanctions were granted for the 
usage of the
 
[[Page 452]]
 
substances listed in Secs. 181.23, 181.24, 181.25, 181.26, 181.27, 
181.28, 181.29, and 181.30 in the manufacture of packaging materials. So 
used, these substances are not considered "food additives" within the 
meaning of section 201(s) of the Act, provided that they are of good 
commercial grade, are suitable for association with food, and are used 
in accordance with good manufacturing practice. For the purpose of this 
subpart, good manufacturing practice for food-packaging materials 
includes the restriction that the quantity of any of these substances 
which becomes a component of food as a result of use in food-packaging 
materials shall not be intended to accomplish any physical or technical 
effect in the food itself, shall be reduced to the least amount 
reasonably possible, and shall not exceed any limit specified in this 
subpart.

"Gas-Solid Chromatographic Procedure for Determining Acrylonitrile 
Monomer in Acrylonitrile-Containing Polymers and Food-Simulating

ratio of 10 milliliters or more per square inch of food-contact surface-
-0.003 milligram/square inch when extracted to equilibrium at 120  deg.F 
with food-simulating solvents appropriate to the intended conditions of 
use.
    (2) In the case of single-use articles having a volume to surface 
ratio of less than 10 milliliters per square inch of food-contact 
surface--0.3 part per million calculated on the basis of the volume of 
the container when extracted to equilibrium at 120  deg.F with food-
simulating solvents appropriate to the intended conditions of use.
    (3) In the case of repeated-use articles--0.003 milligram/square 
inch when extracted at a time equivalent to initial batch usage 
utilizing food-simulating solvents and temperatures appropriate to the 
intended conditions of use.
 
The food-simulating solvents shall include, where applicable, distilled 
water, 8 percent or 50 percent ethanol, 3 percent acetic acid, and 
either n-heptane or an appropriate oil or fat.
    (c) Acrylonitrile monomer may present a hazard to health when 
ingested. Accordingly, any food-contact article containing acrylonitrile 
copolymers or resins that yield acrylonitrile monomer in excess of that 
amount provided for in paragraph (b) of this section shall be deemed to 
be adulterated in violation of section 402 of the Act.
