Abstract
Abstract The present invention relates to thickened personal care compositions which utilize a thickening amount of an acrylate-based polymeric rheology modifier prepared by polymerization of a C 1 -C 6 alkyl ester of acrylic acid and/or a C 1 -C 6 alkyl ester of methacrylic acid, a monomer chosen from a vinyl-substituted heterocyclic compound containing at least one of a nitrogen or sulfur atom, (meth)acrylamide, a mono- or di- (C 1 -C 4 )alkylamino (C 1 -C 4 )alkyl (meth)acrylate, a mono or di-(C 1 -C 4 )alkylamino (C 1 -C 4 )alkyl (meth)acrylamide, and, optionally, an associative monomer.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
179 words
A thickened personal care composition, comprising: a polymeric rheology modifier in amounts effective to thicken
the personal care composition, said polymeric rheology modifier
prepared by polymerization of monomers selected from the group
consisting of from about 5 to about 80 weight percent of an
acrylate monomer (a) selected from the group consisting of a
C 1 -C 6 alkyl ester of acrylic acid and a C 1 -C 6 alkyl ester of
methacrylic acid, from about 5 to about 80 weight percent of a
monomer (b) selected from the group consisting of a vinyl-substituted
heterocyclic compound containing at least one of
a nitrogen or sulfur atom, (meth)acrylamide, a mono- or di(C 1 -C 4 )alkylamino
(C 1 -C 4 )alkyl (meth)acrylate, a mono or di(C 1 -C 4 )alkylamino
(C 1 -C 4 )alkyl (meth)acrylamide; and 0 to about 30 weight percent of an associative
monomer (c), all percentages based on the total weight of
monomer used to prepare the polymeric rheology modifier;
and a cosmetically-active agent in amounts effective to impart
cosmetic properties to the personal care composition.
Claim 2
Dependent Claim
166 words

and 1,2-ethylene oxide, an ethylenically unsaturated copolymerizable
surfactant monomer obtained by condensing a nonionic surfactant with an
α,β-ethylenically unsaturated carboxylic acid or the anhydride thereof, a
surfactant monomer selected from the urea reaction product of a
monoethylenically unsaturated monoisocyanate with a nonionic surfactant
having amine functionality, an allyl ether of the formula CH 2 =CR'CH 2 OA m B n A p R
where R' is hydrogen or methyl, A is propyleneoxy or butyleneoxy, B is
