Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
171 words
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 1 R 2 R 3 N wherein R 1 and R 2 are independently selected from C 10 to C 26 alkyl and alkenyl groups, and R 3 represents a C 1 to C 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).
