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: 10
Claim 1
Independent Claim
140 words
A shampoo that is essentially without liquified propellants and that is poured or otherwise expelled from its container as a viscous liquid that rapidly generates a small, tight-bubbled, voluminous lather consisting essentially of an aqueous solution of (1) water soluble salts of a lauryl sulfate surfactant in an amount of about 5 to 20% by weight of the total composition, (2) a nitrogen containing non-ionic surfactant in amount from about 0.3 to 3% by weight of the total composition, (3) a volatile hydrocarbon or halogenated hydrocarbon boiling in the range of 25° C. to 50° C. at atmospheric pressure in an amount of about 2 to 15% by weight of the total composition, 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
140 words
A shampoo that is essentially without liquified propellants and that is poured or otherwise expelled from its container as a viscous liquid that rapidly generates a small, tight-bubbled, voluminous lather consisting essentially of an aqueous solution of (1) water soluble salts of a lauryl sulfate surfactant in an amount of about 5 to 20% by weight of the total composition, (2) a nitrogen containing non-ionic surfactant in amount from about 0.3 to 3% by weight of the total composition, (3) a volatile hydrocarbon or halogenated hydrocarbon boiling in the range of 25° C. to 50° C. at atmospheric pressure in an amount of about 2 to 15% by weight of the total composition, 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
41 words
A shampoo according to claim 1 wherein part of the water soluble salt of lauryl sulfate is replaced by a different anionic surfactant or amphoteric surfactant but wherein said water soluble salt of lauryl sulfate is the predominant surfactant in (1).
Claim 4
Dependent Claim
16 words
A shampoo according to claim 1 wherein the nitrogen containing non-ionic surfactant is lauryl amine oxide.
Claim 5
Dependent Claim
123 words
A shampoo packaged in an unpressurized container that is an aqueous solution containing water-soluble salts of a lauryl sulfate surfactant 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 atomospheric 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 6
Dependent Claim
123 words
A shampoo packaged in an unpressurized container that is an aqueous solution containing water-soluble salts of a lauryl sulfate surfactant 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 atomospheric 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 7
Dependent Claim
19 words
A shampoo according to claim 1 or 4 wherein the water-soluble salt of lauryl sulfate is ammonium lauryl sulfate.
Claim 8
Dependent Claim
16 words

Claim 9
Dependent Claim
17 words
A shampoo according to claim 1 or 4 wherein the volatile hydrocarbon or halogenated hydrocarbon is n-pentane.
Claim 10
Dependent Claim
