A new moisturizing agent for personal care compositions is provided which is a mono-hydroxy substituted amine salt of a polymer with acid pendant groups. Particularly preferred are dimethylaminoethanol (DMAE) salts of the polymer.
Claims9
A cosmetic composition comprising:
- (i) from about 0.000001 to about 10% by weight of a mono-hydroxy substituted amine salt of a polymer formed from at least one monomer functionalized by an acid group which upon neutralization forms the amine salt;
- and
- (ii) from about 1 to about 99.9% by weight of a cosmetically acceptable carrier.
A cosmetic composition comprising:
- (i) from about 0.000001 to about 10% by weight of a polymer having a plurality of acid groups at least partially neutralized by a mono-hydroxy substituted amine, the amine in non-protonated form having general formula I:
- 2
- wherein R1 and R2 are branched or unbranched C1-C30 radicals selected from the group consisting of alkyl, cycloalkyl, alkenyl, aryl, alkylaryl, alkoxyalkyl and combinations thereof;
- R3 is a branched or unbranched C1-C30 radical selected from the group consisting of alkylene, cycloalkylene, arylene and combinations thereof;
- and
- R1 with R2 can optionally form a ring and independently R1 with R3 can form a ring;
- and
- (ii) from 1 to 99.9% by weight of a cosmetically acceptable carrier.
