Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
119 words
A detergent composition for cleaning and softening fabrics comprising: (a) from 2 to 50% by weight of a detergent-active material selected from the group of anionic, nonionic, zwitterionic and amphoteric synthetic detergent-active materials; (b) from 0.5 to 15% by weight of an amine selected from the group of primary amines having a C 12 -C 26 alkyl or alkenyl group, and secondary amines having the general formula: R.sub.1 R.sub.2 NH wherein R 1 is a C 12 -C 26 alkyl or alkenyl group and R 2 is a C 1 -C 7 alkyl or alkenyl group and (c) from 0.1 to 10% by weight of a bacterial or fungal cellulase having a pH optimum of between 5 and 11.5.
Claim 2
Dependent Claim
119 words
A detergent composition for cleaning and softening fabrics comprising: (a) from 2 to 50% by weight of a detergent-active material selected from the group of anionic, nonionic, zwitterionic and amphoteric synthetic detergent-active materials; (b) from 0.5 to 15% by weight of an amine selected from the group of primary amines having a C 12 -C 26 alkyl or alkenyl group, and secondary amines having the general formula: R.sub.1 R.sub.2 NH wherein R 1 is a C 12 -C 26 alkyl or alkenyl group and R 2 is a C 1 -C 7 alkyl or alkenyl group and (c) from 0.1 to 10% by weight of a bacterial or fungal cellulase having a pH optimum of between 5 and 11.5.
Claim 3
Dependent Claim
17 words
A composition according to claim 1 wherein the cellulase has an optimum activity at alkaline pH values.
Claim 4
Dependent Claim
31 words
A composition according to claim 1 wherein the cellulase has an activity corresponding to at least 0.5 to 25 regular C x cellulase activity units per gram of the detergent composition.
Claim 5
Dependent Claim
23 words
A composition according to claim 1 wherein the amine is a primary amine having a C 12 -C 22 alkyl or alkenyl group.
Claim 6
Dependent Claim
24 words
A composition according to claim 4 in which more than 50% of the amine has a C 16 -C 22 alkyl or alkenyl group.
Claim 7
Dependent Claim
13 words
A composition according to claim 1 comprising 1-10% by weight of the amine.
Claim 8
Dependent Claim
12 words
A composition according to claim 1 comprising 5-40% of the detergent-active material.
