First Claim
Patent Images
1. A hair care composition which comprises (a) one or more polymer systems in the form of discrete polymers of cross-linked polydimethyl siloxane, wherein said polymers have absorbed one or more compatible non-aqueous solvents into their structure so as to increase their volumes, and (b) water or hydroalcoholic solution carrier;
- and wherein said cross-linked polydimethyl siloxanes have as a cross-linker an alpha, omega, aliphatic diene of the following structure;
CH2═
CH(CH2)xCH═
CH2, wherein x ranges from 1-20; and
wherein said non-aqueous solvent is a linear or cyclic polydimethyl siloxane having a viscosity of about 0.5 to about 50 centistokes or mixtures thereof.
