Abstract
Abstract An aqueous liquid or semi-liquid soap composition, for use for example as a shower or bath product, is in the form of a single liquid phase which is preferably transparent. The composition comprises soap chosen from monoethanolamine soaps, diethanolamine soaps or mixtures thereof, and a thickening agent chosen from C 12 to C 18 fatty acids, C 12 to C 18 fatty acid alkanolamides or mixtures thereof.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
206 words
A thickened single liquid phase aqueous soap composition having a viscosity of from 2000 to 10,000 cps, said composition comprising in addition to water: (i) from about 10 to about 25% by weight of a water-soluble or water-dispersible fatty acid soal selected from the group consisting of monoethanolamine fatty acid soaps, diethanolamine fatty acid soaps and mixtures thereof, the fatty acid moiety being derived from a mixture of fatty acids having a carbon chain of from 10 to 18 carbon atoms, the fatty acids being predominantly C 10 to C 14 ; (ii) a first thickening agent selected from the group consisting of C 12 to C 18 fatty acid alkanolamides and mixtures thereof; (iii) a second thickening agent selected from the group consisting of C 12 to C 18 fatty acids and mixtures thereof, the first and second thickening agents together forming from about 1% to about 4% by weight of the composition; and (iv) an effective amount of a perfume, the composition being characterized by its freedom from the problem of phase separation which may occur with other aqueous liquid soap compositions which have a viscosity exceeding 2000 cps and contain a perfume in combination with a soap other than as defined in (i).
Claim 2
Dependent Claim
206 words
A thickened single liquid phase aqueous soap composition having a viscosity of from 2000 to 10,000 cps, said composition comprising in addition to water: (i) from about 10 to about 25% by weight of a water-soluble or water-dispersible fatty acid soal selected from the group consisting of monoethanolamine fatty acid soaps, diethanolamine fatty acid soaps and mixtures thereof, the fatty acid moiety being derived from a mixture of fatty acids having a carbon chain of from 10 to 18 carbon atoms, the fatty acids being predominantly C 10 to C 14 ; (ii) a first thickening agent selected from the group consisting of C 12 to C 18 fatty acid alkanolamides and mixtures thereof; (iii) a second thickening agent selected from the group consisting of C 12 to C 18 fatty acids and mixtures thereof, the first and second thickening agents together forming from about 1% to about 4% by weight of the composition; and (iv) an effective amount of a perfume, the composition being characterized by its freedom from the problem of phase separation which may occur with other aqueous liquid soap compositions which have a viscosity exceeding 2000 cps and contain a perfume in combination with a soap other than as defined in (i).
Claim 3
Dependent Claim
18 words
The composition of claim 1, wherein the C 12 to C 18 fatty acids comprise saturated fatty acids.
Claim 4
Dependent Claim
15 words
The composition of claim 1, wherein the fatty acid alkanolamide is coconut fatty acid diethanolamide.
Claim 5
Dependent Claim
12 words
The composition of claim 1, in the form of a shower gel.
