TITLE 21--FOOD AND DRUGS
CHAPTER I--FOOD AND DRUG ADMINISTRATION, DEPARTMENT OF HEALTH AND HUMAN
SERVICES (CONTINUED)
PART 175 INDIRECT FOOD ADDITIVES: ADHESIVES AND COMPONENTS OF
Subpart C Substances for Use as Components of Coatings
Sec. 175.380 Xylene-formaldehyde resins condensed with
4,4'-isopropylidenediphenol-epichlorohydrin epoxy resins.
The resins identified in paragraph (a) of this section may be safely
used as a food-contact coating for articles intended for use in contact
with food, in accordance with the following prescribed conditions.
(a) The resins are produced by the condensation of xylene-
formaldehyde resin and 4,4'-isopropylidenediphenol-epichlorohydrin epoxy
resins, to which may have been added certain optional adjuvant
substances required in the production of the resins or added to impart
desired physical and technical properties. The optional adjuvant
substances may include resins produced by the condensation of allyl
ether of mono-, di-, or trimethylol phenol and capryl alcohol and also
may include substances identified in Sec. 175.300(b)(3), with the
exception of paragraph (b)(3) (xxxi) and (xxxii) of that section.
(b) The resins identified in paragraph (a) of this section may be
used as a food-contact coating for articles intended for contact at
temperatures not to exceed 160 [deg]F with food of Types I, II, VI-A and
B, and VIII described in table 1 of Sec. 176.170(c) of this chapter
provided that the coating in the finished form in which it is to contact
food meets the following extractives limitations when tested by the
methods provided in Sec. 175.300(e):
(1) The coating when extracted with distilled water at 180 [deg]F
for 24 hours yields total extractives not to exceed 0.05 milligram per
square inch of food-contact surface.
(2) The coating when extracted with 8 percent (by volume) ethyl
alcohol in distilled water at 160 [deg]F for 4 hours yields total
extractives not to exceed 0.05 milligram per square inch of food-contact
surface.
(c) The resins identified in paragraph (a) of this section may be
used as a food-contact coating for articles intended for contact at
temperatures not to exceed room temperature with food of Type VI-C
described in table 1 of Sec. 176.170(c) of this chapter provided the
coating in the finished form in which it is to contact food meets the
following
[[Page 196]]
extractives limitations when tested by the methods provided in Sec.
175.300(e):
(1) The coating when extracted with distilled water at 180 [deg]F
for 24 hours yields total extractives not to exceed 0.05 milligram per
square inch of food-contact surface.
(2) The coating when extracted with 50 percent (by volume) ethyl
alcohol in distilled water at 180 [deg]F for 24 hours yields total
extractives not to exceed 0.05 milligram per square inch.
