Abstract
Abstract A liquid shampoo composition which possesses an excellent foaming power and in which a water-insoluble finely divided powder can be dispersed in a stable condition, in which a stabilizer selected from the group consisting of lower alcohols, glycols and alkanolamines is incorporated in a liquid shampoo composition containing an ammonium salt or an organic amine salt of an anionic surfactant, an ammonium salt or an organic amine salt of water-soluble polyacrylic acid, as principal ingredients, and also containing a fatty acid alkanolamide.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
186 words
A liquid shampoo composition having an excellent foaming power and containing a water-insoluble powder dispersed therein in a stable condition, consisting essentially of: from 5 to 30 wt. % of ammonium salt, monoethanolamine salt, diethanolamine salt, triethanolamine salt or 2-amino-2-methylpropane-1,3-diol salt of anionic, synthetic, organic surfactant effective for shampooing hair; from 0.1 to 1.0 wt. % of water-soluble carboxy vinyl polymer; from 1 to 10 wt. % of a fatty acid alkanolamide having from 10 to 14 carbon atoms in the fatty acid moiety; from 1 to 20 wt. % of a stabilizer selected from the group consisting of alkyl monohydric alcohols having 1 to 3 carbon atoms, glycols having 2 to 6 carbon atoms, monoethanolamine, diethanolamine and triethanolamine; from 0.001 to 5 wt. % of water-insoluble, finely divided powder selected from the group consisting of water-insoluble pigments for shampoos, water-insoluble pearlescent agents for shampoos, water-insoluble hair or scalp-treating medicaments for shampoos and water-insoluble germicides for shampoos; said composition containing an amount of ammonia or an alkanolamine sufficient to maintain the composition at a pH of from 6 to 8; and the balance is essentially water.
Claim 2
Dependent Claim
186 words
A liquid shampoo composition having an excellent foaming power and containing a water-insoluble powder dispersed therein in a stable condition, consisting essentially of: from 5 to 30 wt. % of ammonium salt, monoethanolamine salt, diethanolamine salt, triethanolamine salt or 2-amino-2-methylpropane-1,3-diol salt of anionic, synthetic, organic surfactant effective for shampooing hair; from 0.1 to 1.0 wt. % of water-soluble carboxy vinyl polymer; from 1 to 10 wt. % of a fatty acid alkanolamide having from 10 to 14 carbon atoms in the fatty acid moiety; from 1 to 20 wt. % of a stabilizer selected from the group consisting of alkyl monohydric alcohols having 1 to 3 carbon atoms, glycols having 2 to 6 carbon atoms, monoethanolamine, diethanolamine and triethanolamine; from 0.001 to 5 wt. % of water-insoluble, finely divided powder selected from the group consisting of water-insoluble pigments for shampoos, water-insoluble pearlescent agents for shampoos, water-insoluble hair or scalp-treating medicaments for shampoos and water-insoluble germicides for shampoos; said composition containing an amount of ammonia or an alkanolamine sufficient to maintain the composition at a pH of from 6 to 8; and the balance is essentially water.
Claim 3
Dependent Claim
51 words
A liquid shampoo as claimed in claim 1, containing from 10 to 20 wt. % of said anionic surfactant, from 0.4 to 0.6 wt. % of said carboxy vinyl polymer; from 3 to 5 wt. % of said fatty acid alkanolamide; and from 3 to 10 wt. % of said stabilizer.
Claim 4
Dependent Claim
94 words
A liquid shampoo according to claim 1 or claim 2 in which said anionic surfactant is an ammonium, monoethanolamine, diethanolamine, triethanolamine, or 2-amino-2-methylpropane-1,3-diol salt of alkyl sulfate having 8 to 22 carbon atoms in the alkyl group, polyoxyethylene (1 to 10 moles) alkyl ether sulfate having 8 to 22 carbon atoms in the alkyl group, polyoxyethylene (1 to 10 moles) alkylphenyl ether sulfate having 8 to 12 carbon atoms in the alkyl group, olefin sulfonate having 8 to 22 carbon atoms or alkylbenzene sulfonate having 9 to 18 carbon atoms in the alkyl group.
Claim 5
Dependent Claim
69 words
