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 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.
