Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
73 words
An aqueous shampoo composition comprising, in addition to water, (a) from 2 to 40% by weight of surfactant chosen from anionic, nonionic, or amphoteric surfactants or mixtures thereof; (b) from 0.01 to 3% by weight of cationic conditioning polymer which is a cationic derivative of guar gum; (c) from 0.1 to 10% by weight of an insoluble, non-volatile silicone, present as emulsified particles with an average particle size of less than 2 µm.
Claim 2
Dependent Claim
55 words
A shampoo composition as claimed in claim 1 wherein the anionic surfactant is chosen from sodium lauryl sulphate, triethanolamine lauryl sulphate, triethanolamine monolauryl phosphate, sodium lauryl ether sulphate 2EO, sodium lauryl ether sulphate 3EO, ammonium lauryl sulphate, ammonium lauryl ether sulphate 1EO, ammonium lauryl ether sulphate 2EO, ammonium lauryl ether sulphate 3EO or mixtures thereof.
Claim 3
Dependent Claim
21 words
A shampoo composition as claimed in claim 1 wherein the amphoteric surfactant is C₈₋₁₈ alkyl amidopropyl betaine or C₈₋₁₈ alkyl betaine.
Claim 4
Dependent Claim
20 words
A shampoo composition as claimed in claim 3 wherein the amphoteric surfactant is lauryl betaine, cocamidopropyl betaine or sodium cocamophopropionate.
Claim 5
Dependent Claim
20 words
A shampoo composition as claimed in any preceding claim wherein the cationic derivative of guar gum is guar hydroxypropyltrimonium chloride.
Claim 6
Dependent Claim
24 words
A shampoo composition as claimed in any preceding claim wherein the insoluble, non-volatile silicone is chosen from polyalkyl siloxanes, polyalkylaryl siloxanes, or mixtures thereof.
Claim 7
Dependent Claim
19 words
A shampoo composition as claimed in claim 6 wherein the insoluble, non-volatile silicone is polydimethyl siloxane or polymethylphenyl siloxane.
Claim 8
Dependent Claim
23 words
A shampoo composition as claimed in any preceding claim wherein the silicone has an average particle size of from 0.01 to 1 µm.
Claim 9
Independent Claim
90 words
A method of cosmetically treating hair to deposit insoluble, non-volatile silicone on the hair, which comprises washing the hair with an aqueous shampoo composition comprising - (a) from 2 to 40% by weight of surfactant chosen from anionic, nonionic, or amphoteric surfactants or mixtures thereof; (b) from 0.01 to 3% by weight of cationic conditioning polymer which is a cationic derivative of guar gum; (c) from 0.01 to 10% by weight of an insoluble, non-volatile silicone, present as emulsified particles with an average particle size of less than 2 µm.
Claim 10
Dependent Claim
19 words
The use of a shampoo composition as claimed in any of claim 1 to 8 to wash the hair.
Claim 11
Dependent Claim
64 words
The use of combination of at least 0.01% of a cationic derivative of guar gum and at least 0.1% of an emulsified insoluble, non-volatile silicone, having an average particle size of less than 2 µm, both expressed in terms of the weight of the total composition, for imparting improved conditioning benefit to hair, from a shampoo composition comprising a major proportion of a surfactant.
Claim 12
Independent Claim
51 words
A method of making an aqueous shampoo composition as claimed in any one of claims 1 to 8 comprising mixing together water, the surfactant, the cationic conditioning polymer and an aqueous emulsion of the silicone, wherein the silicone in the emulsion has an average particle size of less than 2 µm.
