## Abstract

The present invention relates to a series of novel silicone polyesters which are prepared by crosslinking an alkyl dimethicone copolyol with a dimer acid. The reaction of the alkyl dimethicone copolyol and dimer acid results in a polyester having affinity to oils and that is highly lubricious on hair, skin and textile fiber.

## Claims

### Claim 1

A polyester made by esterification reaction consisting of reacting:
(a) a dimer acid source selected from
dimer acid conforming to the following structure:
or hydrogenated dimer acid conforming to the following structure:
or mixtures thereof;
with
(b) a dimethicone copolyol conforming to the following structure:
wherein;
a is an integer ranging from 0 to 200;
b is an integer ranging from 2 to 20;
c is an integer ranging from 1 to 20;
d is an integer ranging from 7 to 31;
x, y and z are independently integers ranging from 0 to 20.

### Claim 2 (depends on 1)

A polyester of claim 1 wherein said esterification reaction is conducted at a temperature of between 120° C. and 200° C. for five to 10 hours.

### Claim 3 (depends on 1)

A polyester of claim 1 wherein said dimer acid source is dimer acid.

### Claim 4 (depends on 1)

A polyester of claim 1 wherein said dimer acid source is hydrogenated dimer acid.

### Claim 5 (depends on 1)

A polyester of claim 1 wherein a is an integer ranging from 10 to 50.

### Claim 8

A process for conditioning hair skin and fiber which comprises contacting the hair skin of fiber with an effective conditioning concentration of a polyester made by esterification reaction consisting of reacting:
(a) a dimer acid source selected from
dimer acid conforming to the following structure:
or hydrogenated dimer acid conforming to the following structure:
or mixtures thereof;
with
(b) an alkyl dimethicone copolyol conforming to the following structure:
