Sec. 175.125 Pressure-sensitive adhesives.
Pressure-sensitive adhesives may be safely used as the food-contact
surface of labels and/or tapes applied to food, in accordance with the
following prescribed conditions:
(a) Pressure-sensitive adhesives prepared from one or a mixture of
two or more of the substances listed in this paragraph may be used as
the food-contact surface of labels and/or tapes applied to poultry, dry
food, and processed, frozen, dried, or partially dehydrated fruits or
(1) Substances generally recognized as safe in food.
(2) Substances used in accordance with a prior sanction or approval.
(3) Color additives listed for use in or on food in parts 73 and 74
of this chapter.
(4) Substances identified in Sec. 172.615 of this chapter other
than substances used in accordance with paragraph (a)(2) of this
(5) Polyethylene, oxidized; complying with the identity prescribed
in Sec. 177.1620(a) of this chapter.
(6) 4-[[4, 6-Bis(octylthio)-s-triazin-2-yl]amino]-2,6-di-tert-
butylphenol (CAS Reg. No. 991-84-4) as an antioxidant/stabilizer at a
level not to exceed 1.5 percent by weight of the finished pressure-
(7) 2,2'-(2,5-Thiophenediyl)-bis(5-tert-butylbenzoxazole) (CAS Reg.
No. 7128-64-5) as an optical brightener at a level not to exceed 0.05
percent by weight of the finished pressure-sensitive adhesive.
(8) 2-Hydroxy-1-[4-(2-hydroxyethoxy) phenyl]-2-methyl-1-propanone
(CAS Reg. No. 106797-53-9) as a photoinitiator at a level not to exceed
5 percent by weight of the pressure-sensitive adhesive.
(9) Butanedioic acid, sulfo-1,4-di-(C9-C11
alkyl) ester, ammonium salt (also known as butanedioic acid sulfo-1, 4-
diisodecyl ester, ammonium salt [CAS Reg. No. 144093-88-9]) as a surface
active agent at a level not to exceed 3.0 percent by weight of the
finished pressure-sensitive adhesive.
(b) Pressure-sensitive adhesives prepared from one or a mixture of
two or more of the substances listed in this
paragraph may be used as the food-contact surface of labels and/or tapes
applied to raw fruit and raw vegetables.
(1) Substances listed in paragraphs (a)(1), (a)(2), (a)(3), (a)(5),
(a)(6), (a)(7), (a)(8), and (a)(9) of this section, and those substances
prescribed by paragraph (a)(4) of this section that are not identified
in paragraph (b)(2) of this section.
(2) Substances identified in this subparagraph and subject to the
Butylated reaction product of p-cresol and dicyclopentadiene produced by
reacting p-cresol and dicyclopentadiene in an approximate mole ratio of
1.5 to 1.0, respectively, followed by alkylation with isobutylene so
that the butyl content of the final product is not less than 18 percent,
for use at levels not to exceed 1.0 percent by weight of the adhesive
Chlorinated natural rubber.
Polybutene, hydrogenated; complying with the identity prescribed under

and condensates with phenol, formaldehyde, coumarone, and/or indene.
Tri(mixed mono- and dinonylphenyl) phosphite (which may contain not more
than 1 percent by weight of triisopropanolamine).
(c) Acrylonitrile copolymers identified in this section shall comply
with the provisions of Sec. 180.22 of this chapter.
