## Abstract

This invention relates to a novel class of Dimer Alkyl Silicone Polymers (DASP) and their use to provide conditioning to skin and hair. By conditioning is meant a elegant smooth skin feel, eliminating dryness and raspiness. It is thought the mechanism of action is related to the fact that the DASP compounds reduce surface tension of personal care products, providing outstanding conditioning and skin feel. The improved conditioning composition based upon a very specific class of dimer alkyl silicone polymers (DASP) that despite their solubility in oil, lower surface tension and improve conditioning of personal care products.

## Claims

### Claim 1

A process for conditioning hair or skin which comprises contacting the hair or skin with an effective conditioning concentration of a polymer conforming to the following structure;
wherein:
a is an integer ranging from 1 to 200;
b is 1;
c is an integer ranging from 1 to 20;
d is an integer ranging from 11 to 15;
with the proviso that the ratio of a to c ranges from 1:1 to 10:1;
R is
e is an integer ranging from 10 to 100.

### Claim 2 (depends on 1)

A process of claim 1 wherein said effective conditioning concentration ranges from 0.1 to 20% by weight.

### Claim 3 (depends on 1)

A process of claim 1 wherein d is 11.

### Claim 4 (depends on 1)

A process of claim 1 wherein d is 15.

### Claim 5 (depends on 2)

A process of claim 2 wherein d is 11.

### Claim 6 (depends on 2)

A process of claim 2 wherein d is 15.
