14 Claims

1. A cosmetic composition comprising an uncured silicone based polymer; and at least one cosmetic ingredient, optionally in a cosmetically acceptable medium;

wherein the uncured silicone based polymer is linear or branched and has the general formula:

(R¹O)_3-x—Si(R²)_x—(Z)_d—(O)_q—(R³₂SiO)_N—(SiR³₂—Z)_d—Si(R²)_y(OR¹)_3-y

where:

x is 0 or 1;

y is 0, 1, 2, or 3;

N is from 300 to 10,000;

d is 0 or 1, q is 0 or 1, and d+q=1;

R¹, R²and R³are each independently linear alkyl groups containing 1 to 10 carbons; and

each Z is independently either

(i) a linear or branched alkylene group having from 1 to 12 carbon atoms which may be interrupted by one or more linear or branched siloxane groups comprising from 1 to 20 silicon atoms; or

(ii) an organic chain based on polyoxyalkylene based units which may be interrupted by one or more linear or branched siloxane groups comprising from 1 to 20 silicon atoms;

wherein the cosmetic composition is in the form of a shampoo, a cream, a rinse-off conditioner, a leave-in conditioner, or a gel.
