Abstract
Abstract Shampoo compositions are provided in unpressurized containers that generate a small, tight-bubbled lather more rapidly and more profusely than conventional shampoos, thereby improving the ease with which the shampoo is spread through the hair and rinsed away, resulting in more uniform cleansing. The compositions contain an aqueous solution of a water-soluble salt of lauryl sulfate, a volatile hydrocarbon or halogenated hydrocarbon boiling in the range of 25°C to 50°C, a tertiary amine oxide, and a sufficient amount of water-soluble gum to give the shampoo a viscosity in the range of about 1000 to 20,000 centistokes at 5°C.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
88 words
A shampoo that rapidly generates a small, tight-bubbled, voluminous lather consisting of (1) an aqueous solution of a surfactant selected from the group consisting of anionic and amphoteric surfactants but predominantly one or more water-soluble salts of lauryl sulfate, (2) a nitrogen-containing non-ionic surfactant, (3) a volatile hydrocarbon or halogenated hydrocarbon boiling in the range of 25°C to 50°C at atmospheric pressure, and (4) a compatible water-soluble gum in sufficient quantity to give the shampoo a viscosity in the range of about 1000 to 20,000 centistokes at 5°C.
Claim 2
Dependent Claim
88 words
A shampoo that rapidly generates a small, tight-bubbled, voluminous lather consisting of (1) an aqueous solution of a surfactant selected from the group consisting of anionic and amphoteric surfactants but predominantly one or more water-soluble salts of lauryl sulfate, (2) a nitrogen-containing non-ionic surfactant, (3) a volatile hydrocarbon or halogenated hydrocarbon boiling in the range of 25°C to 50°C at atmospheric pressure, and (4) a compatible water-soluble gum in sufficient quantity to give the shampoo a viscosity in the range of about 1000 to 20,000 centistokes at 5°C.
Claim 3
Dependent Claim
130 words
A shampoo that is an aqueous solution containing a surfactant selected from the group consisting of anionic and amphoteric surfactants but predominantly one or more water-soluble salts of lauryl sulfate in an amount of about 5 to 20% by weight of the total composition, a tertiary amine oxide with a long hydrocarbon chain having 12 to 14 carbon atoms in an amount of about 0.3 to 3% by weight of the total composition, a volatile hydrocarbon or halogenated hydrocarbon boiling in the range of 25°C to 50°C at atmospheric pressure in the amount of about 2 to 15% by weight of the total compositions, and a sufficient quantity of a compatible water-soluble gum to give the shampoo a viscosity in the range of about 1000 to 20,000 centistokes at 5°C.
Claim 4
Dependent Claim
130 words
A shampoo that is an aqueous solution containing a surfactant selected from the group consisting of anionic and amphoteric surfactants but predominantly one or more water-soluble salts of lauryl sulfate in an amount of about 5 to 20% by weight of the total composition, a tertiary amine oxide with a long hydrocarbon chain having 12 to 14 carbon atoms in an amount of about 0.3 to 3% by weight of the total composition, a volatile hydrocarbon or halogenated hydrocarbon boiling in the range of 25°C to 50°C at atmospheric pressure in the amount of about 2 to 15% by weight of the total compositions, and a sufficient quantity of a compatible water-soluble gum to give the shampoo a viscosity in the range of about 1000 to 20,000 centistokes at 5°C.
Claim 5
Dependent Claim
23 words
A shampoo as claimed in claim 1 or claim 2 characterised in that the water-soluble salt of lauryl sulfate is ammonium lauryl sulfate.
Claim 6
Dependent Claim
23 words
A shampoo as claimed in any of claims 1 to 3 characterised in that the tertiary amine oxide is lauryl dimethyl amine oxide.
Claim 7
Dependent Claim

A shampoo as claimed in any of claims 1 to 4 characterised in that the volatile hydrocarbon or halogenated hydrocarbon is n-pentane.
Claim 8
Dependent Claim
22 words
A shampoo as claimed in any of claims 1 to 5 characterised in that the compatible water-soluble gum is a cellulosic gum.
Claim 9
Dependent Claim
21 words
A shampoo as claimed in any of claims 1 to 6 characterised in that it is packaged in an unpressurised container.
