Detergent Compositions and Their Use
Use of a detergent composition comprising an amine oxide surfactant, at least one branched nonionic surfactant and at least one anionic component for enhancing particulate soil removal from a fabric washed in a wash liquor containing the detergent composition.
1 . Use of a detergent composition comprising an amine oxide surfactant, at least one branched nonionic surfactant and at least one anionic component for enhancing particulate soil removal from a fabric washed in a wash liquor containing the detergent composition.
2 . Use according to claim 1 , wherein the at least one anionic component is selected from anionic detersive surfactants, fatty acids, salts of fatty acids and mixtures thereof.
3 . Use according to claim 2 , comprising a fatty acid and/or a salt thereof which comprises at least 17 carbon atoms.
4 . Use according to claim 2 , wherein the fatty acid and/or salt thereof is or are selected from saturated and monounsaturated C 17 -C 18 fatty acids and their salts.
5 . Use according to claim 2 , wherein the fatty acid and/or salt thereof is or are selected from oleic acid and isostearic acid and their salts.
6 . Use according to claim 2 , wherein the anionic detersive surfactants is or are selected from (poly)alkoxylated alkyl sulphate surfactants.
7 . Use according to claim 6 , wherein the (poly)alkoxylated alkyl sulphate surfactants comprise ethoxylated sulphates having from 1 to 3 ethyleneoxide units per molecule.
8 . Use according to claim 1 , wherein the detergent composition is a liquid detergent composition, preferably an aqueous liquid detergent composition.
9 . Use according to claim 1 , wherein the amine oxide has the general formula (I):—
R 1 R 2 ( N ) R 3 →0 (I)
wherein R 1 and R 2 are independently C 1 -C 4 alkyl or hydroxyl-C 1 -C 4 alkyl groups and R 3 is a C 8 to C 18 alkyl or alkenyl group.
10 . A detergent composition comprising an amine oxide surfactant, at least one branched nonionic surfactant and at least one fatty acid or salt thereof having at least 17 carbon atoms.
11 . A detergent composition according to claim 10 , wherein the fatty acid and/or salt thereof is or are selected from saturated and monounsaturated C 17 -C 18 fatty acids and their salts.
12 . A detergent composition according to claim 10 , wherein the fatty acid and/or salt thereof is or are selected from oleic acid and isostearic acid and their salts.
13 . A detergent composition according to claim 10 , comprising from 0.1% to 10%, preferably from 0.5% to 5% by weight of the total composition of the amine oxide surfactant.
14 . A detergent composition according to claim 10 , comprising from 0.5% to 15%, preferably from 1% to 10% by weight of the composition of the fatty acid and/or fatty acid salt.
15 . A detergent composition according to claim 10 , in the form of a liquid detergent composition, preferably an aqueous liquid detergent composition.
16 . A detergent composition according to claim 10 , wherein the amine oxide has the general formula (I):—
R 1 R 2 ( N ) R 3 →0 (I)
wherein R 1 and R 2 are independently C 1 -C 4 alkyl or hydroxyl-C 1 -C 4 alkyl groups and R 3 is a C 8 to C 18 alkyl or alkenyl group.
