Patent Images
1. A base composition comprising:
- A) a silicone fluid, B) a silicone immiscible organic substance, C) a siloxane-based polyamide having the formula;
where, (1) DP (degree of polymerization) is 1-700, (2) n is 1-500, (3) X is a linear or branched chain alkylene having 1-30 carbons, (4) Y is a linear or branched chain alkylene having 1-40 carbons,
wherein, (a) the alkylene group may optionally and additionally contain in the alkylene portion at least one of (i) 1-3 amide linkages;
(ii) a C5 or C6 cycloalkane;
or (iii) phenylene, optionally substituted by 1-3 members which are independently C1-C3 alkyls;
(b) the alkylene group itself may optionally be substituted by at least one of (i) hydroxy;
(ii) a C3-C8 cycloalkane;
(iii) 1-3 members which are independently C1-C3 alkyls;
phenyl, optionally substituted by 1-3 members which are independently C1-C3 alkyls;
(iv) a C1-C3 alkyl hydroxy;
or (v) a C1-C6 alkyl amine;
(c) Y can be Z where Z is T(R20)(R21)(R22) where R20, R21 and R22 are each independently linear or branched C1-C10 alkylenes; and
T is CR in which R is hydrogen, the group defined for R1-R4, or a trivalent atom such as N, P and Al;
(5) each of R1-R4 is independently methyl, ethyl, propyl, isopropyl, a siloxane chain, or phenyl, wherein the phenyl may optionally be substituted by 1-3 members, which are methyl or ethyl;
(6) X, Y, DP, and R1-R4 may be the same or different for each polyamide unit, wherein the base composition is a stable dispersion.

Abstract
Hair and skin care compositions containing siloxane-based polyamides are disclosed, some of which utilize a base composition comprising a silicone fluid, a silicone immiscible substance, and a siloxane-based polyamide. The siloxane-based polyamide functions as a compatibilizing agent, film forming agent and durability enhancer in these hair and skin care compositions. A method of enhancing the fragrance longevity of fragrance containing skin care compositions after application is also disclosed.
