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, alkyloxyalkylene 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 oxyalkylene 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 quaternizing agents, e.g., alkylation reagents.
A composition comprising a fibrous material and a lubricant wherein the lubricant comprises a cationic silicone produced by reacting an aminosilicone with a quaternizing agent which aminosilicone has the formula:
A composition comprising a cationic silicone and at least one additive selected from among emollients, cleaning agents, surfactants, detergency builder materials, bleaches, fillers, electrolytes, emulsifiers, viscosity modification agents, thickeners, and waxes, wherein the cationic silicone has the formula the cationic silicone which is produced by reacting an aminosilicone with a quaternizing agent, which aminosilicone comprises:
A composition comprising a flexible substrate material and the cationic silicone which is produced by reacting an aminosilicone with a quaternizing agent, which aminosilicone has the formula:
