Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
58 words
An alkaline detergent composition for the cleaning and softening of fabrics comprising: (a) from 2 to 50% by weight of an anionic surfactant and/or nonionic surfactant; (b) from 0.5 to 15% by weight of a cationic fabric-softening compound; and (c) from 0 to 80% by weight of a detergency builder, characterized in that it contains a fungal cellulase.
Claim 2
Dependent Claim
58 words
An alkaline detergent composition for the cleaning and softening of fabrics comprising: (a) from 2 to 50% by weight of an anionic surfactant and/or nonionic surfactant; (b) from 0.5 to 15% by weight of a cationic fabric-softening compound; and (c) from 0 to 80% by weight of a detergency builder, characterized in that it contains a fungal cellulase.
Claim 3
Dependent Claim
18 words
A composition according to claim 1, comprising a fungal cellulase having an optimum activity at alkaline pH values.
Claim 4
Dependent Claim
18 words
A composition according to claim 1 or 2, comprising from 0.1 to 10% by weight of the cellulase.
