Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
166 words
A textile softening detergent composition containing from 3% to 30% by weight of an organic surfactant, and from 10% to 80% of one or more water soluble inorganic or organic salts such that the pH of a 0.5% by weight aqueous solution of the composition is in the range from 8.5 to 11 characterised in that it comprises as the textile softening component, the combination of (a) from 1% to 25% of a tertiary amine having the formula wherein R, represents a C 10 to C 26 alkyl or alkenyl group, R 2 represents a group defined as for R, or where R, is a C 16 -C 26 alkyl group, R 2 may be a C 1 to C 7 alkyl group, and R 3 represents a C 1 to C 7 alkyl group, or of a mixture of said amines, and (b) from 1.5% to 35% of an impalpable smectite-type clay having an ion exchange capacity of at least 50 meq. per 100 grams.
Claim 2
Dependent Claim
166 words
A textile softening detergent composition containing from 3% to 30% by weight of an organic surfactant, and from 10% to 80% of one or more water soluble inorganic or organic salts such that the pH of a 0.5% by weight aqueous solution of the composition is in the range from 8.5 to 11 characterised in that it comprises as the textile softening component, the combination of (a) from 1% to 25% of a tertiary amine having the formula wherein R, represents a C 10 to C 26 alkyl or alkenyl group, R 2 represents a group defined as for R, or where R, is a C 16 -C 26 alkyl group, R 2 may be a C 1 to C 7 alkyl group, and R 3 represents a C 1 to C 7 alkyl group, or of a mixture of said amines, and (b) from 1.5% to 35% of an impalpable smectite-type clay having an ion exchange capacity of at least 50 meq. per 100 grams.
Claim 3
Dependent Claim

Claim 5
Dependent Claim
49 words
A detergent composition according to any one of Claims 1 to 3 which contains by weight from 2% to 15% of an amine of formula wherein R 1 and R 2 each independently represents a C 12 to C 22 alkyl group and R 3 is methyl or ethyl.
