TITLE 21--FOOD AND DRUGS
CHAPTER I--FOOD AND DRUG ADMINISTRATION, DEPARTMENT OF HEALTH AND HUMAN
SERVICES (CONTINUED)
PART 172 FOOD ADDITIVES PERMITTED FOR DIRECT ADDITION TO FOOD FOR HUMAN
Subpart I Multipurpose Additives
Sec. 172.808 Copolymer condensates of ethylene oxide and propylene
oxide.
Copolymer condensates of ethylene oxide and propylene oxide may be
safely used in food under the following prescribed conditions:
(a) The additive consists of one of the following:
(1) [alpha]-Hydro-omega-hydroxy-poly (oxyethylene)
poly(oxypropylene)-(55-61 moles)poly(oxyethylene) block copolymer,
having a molecular weight range of 9,760-13,200 and a cloud point above
100 [deg]C in 1 percent aqueous solution.
(2) [alpha]-Hydro-omega-hydroxy-poly (oxy
ethylene)poly(oxypropylene)-(53-59 moles)poly(oxyethylene)(14-16 moles)
block copolymer, having a molecular weight range of 3,500-4,125 and a
cloud point of 9 [deg]C-12 [deg]C in 10 percent aqueous solution.
(3) [alpha]-Hydro-omega-hydroxy-poly(ox-yethylene)/
poly(oxypropylene) (minimum 15 moles)/poly(oxyethylene) block copolymer,
having a minimum average molecular weight of 1900 and a minimum cloud
point of 9 [deg]C-12 [deg]C in 10 percent aqueous solution.
(4) [alpha]-Hydro-omega-hydroxy-poly(ox-yethylene) poly
(oxypropylene)-(51-57 moles) poly(oxyethylene) block copolymer, having
an average molecular weight of 14,000 and a cloud point above 100 [deg]C
in 1 percent aqueous solution.
(b) The additive is used or intended for use as follows:
(1) The additive identified in paragraph (a)(1) of this section is
used in practice as a solubilizing and stabilizing agent in flavor
concentrates (containing authorized flavoring oils) for use in foods for
which standards of identity established under section 401 of the Act do
not preclude such use, provided that the weight of the additive does not
exceed the weight of the flavoring oils in the flavor concentrate.
(2) The additive identified in paragraph (a)(2) of this section is
used as a processing aid and wetting agent in combination with dioctyl
sodium sulfosuccinate for fumaric acid as prescribed in Sec. 172.810.
(3) The additive identified in paragraph (a)(3) of this section is
used:
[[Page 81]]
(i) As a surfactant and defoaming agent, at levels not to exceed
0.05 percent by weight, in scald baths for poultry defeathering,
followed by potable water rinse. The temperatures of the scald baths
shall be not less than 125 [deg]F.
(ii) As a foam control and rinse adjuvant in hog dehairing machines
at a use level of not more than 5 grams per hog.
(4) The additive identified in paragraph (a)(4) of this section is
used as a dough conditioner in yeast-leavened bakery products for which
standards of identity established under section 401 of the Act do not
preclude such use, provided that the amount of the additive dose not
exceed 0.5 percent by weight of the flour used.
