Abstract

Abstract An improved laundry detergent composition which combines effective cleaning performance with effective textile softening performance on a wide range of textile materials comprises an anionic and/or nonionic surfactant and a synergistic mixture of a water-insoluble long chain C 10 -C 26 tertiary amine and cellulase. The cellulase is preferably an alkali cellulase having an optimum pH of above 7 and is preferably used in an amount corresponding to a cellulase activity of from 0.25 to 150 or higher regular Cx cellulase activity units/gram of the detergent composition.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 160 words
A detergent composition for the cleaning and softening of fabrics, comprising 2-50% by weight of an anionic surfactant and/or a nonionic surfactant and 0.5-15% by weight of a tertiary amine having the general formula: wherein R 1 is a C 10 -C 26 alkyl or alkenyl group, R 2 is as R 1 or, if R 1 is a C 20 -C 26 alkyl or alkenyl group, may be a C 1 -C 7 alkyl group and R 3 has the formula - CH 2 - Y wherein Y is H, C 1 -C 6 alkyl, - CH 2 0H, -CH = CH 2 , wherein R 4 is a C l -C 4 alkyl group, each R 5 is independently H or C 1 -C 20 alkyl; and each R 6 is independently H or C 1 -C 20 alkyl; characterized in that it further contains cellulase, which together with said tertiary amine forms the essential fabric softening ingredients.
Claim 2
Dependent Claim 160 words
A detergent composition for the cleaning and softening of fabrics, comprising 2-50% by weight of an anionic surfactant and/or a nonionic surfactant and 0.5-15% by weight of a tertiary amine having the general formula: wherein R 1 is a C 10 -C 26 alkyl or alkenyl group, R 2 is as R 1 or, if R 1 is a C 20 -C 26 alkyl or alkenyl group, may be a C 1 -C 7 alkyl group and R 3 has the formula - CH 2 - Y wherein Y is H, C 1 -C 6 alkyl, - CH 2 0H, -CH = CH 2 , wherein R 4 is a C l -C 4 alkyl group, each R 5 is independently H or C 1 -C 20 alkyl; and each R 6 is independently H or C 1 -C 20 alkyl; characterized in that it further contains cellulase, which together with said tertiary amine forms the essential fabric softening ingredients.
Claim 3
Dependent Claim 26 words
A detergent composition according to claim 1, characteried in that the cellulase is bacterial or fungal cellulase having a pH optimum of between 5 and 11.5.
Claim 4
Dependent Claim 29 words
A detergent composition according to claim 1 or 2, characterized in that the cellulase is alkali cellulase having an optimum pH greater than 7, preferably from 7.5 to 11.0.
Claim 5
Dependent Claim 37 words
A detergent composition according to claim 1, 2 or 3, characterized in that the cellulase is present in the form of a non-dusting granulate having a cellulase activity of at least 250 regular C cellulase activity units/gram.
Claim 6
Dependent Claim 26 words
A detergent composition according to claim 4, characterized in that the cellulase is present in an amount of from about 0.1-10% by weight of the composition.
Claim 7
Dependent Claim 28 words
A detergent composition according to any of the preceding claims, characterized in that the composition has a cellulase activity of from 0.25 to 150 regular C x units/gram.
Claim 8
Dependent Claim 26 words
A detergent composition according to claim 6, characterized in that the cellulase activity is from 0.5 to 25 regular C x units per gram of composition.
Claim 9
Dependent Claim 43 words
A detergent composition according to claim 1, characterized in that the tertiary amine is selected from compounds in which R 1 and R 2 are each independently C 12 - C 22 alkyl groups and R 3 is a methyl or ethyl group.
Claim 10
Dependent Claim 17 words
A detergent composition according to claim 8, characterized in that the tertiary amine is ditallowyl methyl amine.
