Claims11
A personal care composition comprising:
- (a) a silicone grafted adhesive polymer having a Tg of from about −20° C. to about 60° C., and comprising an organic polymeric backbone, wherein the backbone is formed from
- (i) at least one low Tg monomer which forms a homopolymer having a Tg of from about −120° C. to about −20° C., wherein the low Tg monomer is selected from the group consisting of:
- 3-methoxybutyl acrylate, 2-methoxyethyl acrylate, 2-phenoxyethyl ester, 4-hydroxybutyl acrylate, 2-ethoxyethoxyethyl acrylate, 2-ethoxyethyl acrylate, n-butyl acrylate, 2-ethylhexyl acrylate, 2-ethylbutyl acrylate, n-ethyl acrylate, n-heptyl acrylate, n-hexyl acrylate, iso-butyl acrylate, iso-decyl acrylate, 3-methylbutyl acrylate, 2-methylpentyl acrylate, nonyl acrylate, octyl acrylate, N-dodecylacrylamide, N-octyldecylacrylamide, vinyl propionate, vinyl butyrate, 4-decylstyrene, isobutylene, 1-butene, 5-methyl-1-hexene, isoprene, 1,2-butadiene, 1,4-butadiene and mixtures thereof;
- and
- (ii) at least one high Tg monomer which forms a homopolymer having a Tg of from about 25° C. to about 250° C., wherein the high Tg monomer is selected from the group consisting of acrylic acid and methacrylic acid monomers;
- wherein the silicone grafted adhesive polymer has silicone macromers grafted to said backbone;
- and further wherein the number average molecular weight of the silicone macromers is from about 1,000 to about 50,000;
- and
- (b) a personal care carrier.

- 3-methoxybutyl acrylate, 2-methoxyethyl acrylate, 2-phenoxyethyl ester, 4-hydroxybutyl acrylate, 2-ethoxyethoxyethyl acrylate, 2-ethoxyethyl acrylate, n-butyl acrylate, 2-ethylhexyl acrylate, 2-ethylbutyl acrylate, n-ethyl acrylate, n-heptyl acrylate, n-hexyl acrylate, iso-butyl acrylate, iso-decyl acrylate, 3-methylbutyl acrylate, 2-methylpentyl acrylate, nonyl acrylate, octyl acrylate, N-dodecylacrylamide, N-octyldecylacrylamide, vinyl propionate, vinyl butyrate, 4-decylstyrene, isobutylene, 1-butene, 5-methyl-1-hexene, isoprene, 1,2-butadiene, 1,4-butadiene and mixtures thereof;
- and
- (ii) at least one high Tg monomer which forms a homopolymer having a Tg of from about 25° C. to about 250° C., wherein the high Tg monomer is selected from the group consisting of acrylic acid and methacrylic acid monomers;
- wherein the silicone grafted adhesive polymer has silicone macromers grafted to the backbone;
- and further wherein the number average molecular weight of the silicone macromers is from about 1,000 to about 50,000;
- and
- (b) a solvent carrier.
