Abstract
The present invention provides novel N-aralkylcarbonyldiamine compounds having a structure as set forth in Structure I. The structures are not quaternized. When these novel unquaternized compounds are used in personal care compositions, particularly personal care skin compositions, they are more stable and provide unexpected cosmetic advantages (e.g., against wrinkles, aging skin, etc.) when delivered from the personal care skin compositions.
Claims7
An N-aralkylcarbonyldiamine compound having structure I noted below:
- wherein n=2, R1 is hydroxyl, R2 is selected from cyclohexyl or cyclopentyl, R3 is selected from the group consisting of C1-C3 alkyl, and R4 and R5 are selected from the group consisting of C1-C6 alkyl, wherein said C1 to C6 alkyl group is linear, cyclic or branched and amine salts thereof.
A personal care composition comprising:
- a) about 0.001 to 20% by wt. of composition of a compound selected from the group consisting of (i) N-aralkylcarbonyldiamine compound or compounds, (ii) mixtures of (i) where said N-aralkylcarbonyldiamine compound has Structure I noted below:
- wherein n=2, R1 is hydroxyl, R2 is selected from cyclohexyl or cyclopentyl, R3 is selected from the group consisting of C1-C3 alkyl, and R4 and R5 are selected from the group consisting of C1-C6 alkyl, wherein said C1-C6 alkyl group is linear, cyclic or branched, and amine salts thereof;
- and
- b) a cosmetically acceptable vehicle which may range from 5 to 99% by weight of the composition;
- and
- c) optional skin benefit material and/or cosmetic adjunct.
