## Abstract

A cationic silicone compound which can be employed in a variety of environments, such as a fiber lubricant, textile fabric softener, hair conditioner, and skin conditioner is formed from an aminosilicone compound which has the following Formula (I): ##STR1## wherein a, b, and c are 0-300; d is 0-4, preferably 1 or 2; R.sub.1 comprises hydrogen, an alkyl, aryl, alkynyl, alkenyl, oxyalkylene group which may be unsubstituted or substituted with P,N, or S moieties; R.sub.2 is defined the same as R.sub.1 and can also be a carboxylic acid residue preferably a fatty acid residues, with the proviso that where R.sub.2 is a carboxylic acid residue, the R.sub.1 attached to the terminal N is hydrogen; R.sub.3 is defined the same as R.sub.2 and can also be alkoxy, aryloxy or alkyloxyalkylene groups; R.sub.4 is defined the same as R.sub.3 and can also be an amino-substituted alkyl group; Z.sub.1 and Z.sub.2 can be the same or different and comprise an alkyl, aryl, alkenyl or alkynyl group with the proviso that if b is 0, then at least one of the R.sub.4 groups comprises an amino-substituted alkyl group. In particular, the aminosilicone is quaternized using known quarternizing agents, e.g., alkylation reagents.

## Claims

### Claim 1

An aminosilicone compound represented by the following formula: ##STR25## wherein a and c are 0-300; b is 1-300;
d is 0-4;
R.sub.1 and R.sub.2, both comprise an oxyalkylene group substituted with P,N, or S moieties;
R.sub.3 and R.sub.4 are the same or different and comprise an alkyl group or an alkyloxyalkylene group;
Z.sub.1 and Z.sub.2 are the same or different and comprise an alkyl group.

### Claim 2 (depends on 1)

The aminosilicone compound of claim 1 wherein at least one R.sub.3 comprises an alkyloxyalkylene group.

### Claim 3 (depends on 2)

The aminosilicone compound of claim 2 where d is 1.
