Detergent compositions containing nonionic and cationic surfactants, the cationic surfactant having a long alkyl chain of from about 20 to about 30 carbon atoms
First Claim
1. A detergent composition, containing from 0 to about 20% phosphate materials, comprising from about 5% to about 100% of a surfactant mixture consisting essentially of:
- (a) a nonionic surfactant having an HLB of from about 5 to about 17; and
(b) a cationic surfactant having the formula R(R'"'"')3 N+ Z-, wherein R is an alkyl group containing an average of from about 20 to about 30 carbon atoms, each R'"'"' is an alkyl or hydroxyalkyl group containing from 1 to 4 carbon atoms, or a benzyl group with no more than one R'"'"' in a molecule being benzyl, and Z is an anion selected from the group consisting of halides, hydroxide, nitrate, sulfate, and alkyl sulfates;
the ratio, by weight, of said nonionic surfactant to said cationic surfactant being from about 3;
1 to about 15;

Abstract
Laundry detergent compositions, which are either free of phosphate materials or contain only low levels of such materials, containing a nonionic surfactant, preferably specific alcohol ethoxylate nonionic surfactants, together with selected single long chain (C20 --C30) alkyl cationic surfactants, are disclosed. These compositions provide both excellent particulate and greasy/oily soil removal and, additionally, provide fabric softening, static control, color fidelity, and dye transfer inhibition benefits to fabrics laundered therewith. A process for laundering fabrics, using these compositions, is also disclosed.
