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; PA1 R.sub.1 comprises hydrogen, an alkyl, aryl, alkynyl, alkenyl, oxyalkylene group which may be unsubstituted or substituted with P,N, or S moieties; PA1 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; PA1 R.sub.3 is defined the same as R.sub.2 and can also be alkoxy, aryloxy or alkyloxyalkylene groups; PA1 R.sub.4 is defined the same as R.sub.3 and can also be an amino-substituted alkyl group; PA1 Z.sub.1 and Z.sub.2 can be the same or different and comprise an alkyl, aryl, alkenyl or alkynyl group PA1 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 quarterni…
