Hair and skin care compositions containing siloxane-based polyamide copolymers

A base composition comprising:

• A) a silicone fluid,
• B) a silicone immiscible organic substance,
• C) a siloxane-based polyamide having the formula;
• 3
• 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.
