Abstract
Laundry detergent compositions are provided which contain an effective textile softening agent which does not reduce their cleaning performance. The softening agent comprises a specified class of tertiary amines together with a smectite-type clay.
Claims5
A textile softening composition consisting essentially of, by weight,
- (a) from about 5% to about 20% of anionic organic surfactant;
- (b) from about 2% to about 8% of tertiary amine having the formula R.sub.1 R.sub.2 R.sub.3 N wherein R.sub.1 and R.sub.2 are independently selected from C.sub.10 to C.sub.26 alkyl and alkenyl groups, and R.sub.3 represents a C.sub.1 to C.sub.7 alkyl group;
- (c) from about 1.5% to about 12% of impalpable smectite-type clay having an ion exchange capacity of at least about 50 meq per 100 grams;
- and
- (d) from about 20% to about 60% of one or more water-soluble detergency builder salts;
- wherein the weight ratio of tertiary amine to smectite-type clay is in the range from about 2:1 to 1:2 and wherein the pH of a 0.5% by weight aqueous solution of the composition is in the range from 8.5 to 11.0;
- wherein the amine component (b) is disposed on the surface of granules comprising components (a), (c), and (d).
