Abstract

Abstract A preparation for the hygiene and the cleaning of skin, scalp and hair, essentially comprising 5.0% to 10.0% of an emulsifying agent containing an HLB 10-19 nonionic emulsifier and 0.5 to 5.0% of a thickening agent consisting of organic substances forming with the water gels or colloidal solutions. Such a preparation is endowed with a mild and delicate cleaning action, and is surprisingly lacing of any irritating effect.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 175 words
In aqueous preparations for hygenic uses and, cleaning of skin, scalp and hair, selected from the group consisting of: (a) about 5 to about 10% of an emulsifying agent, and having an HLB emulsifying power of between 10 and 19; and (b) about 0.5 to about 5% of a thickening agent capable of forming gels and colloidal solutions in the presence of water, wherein the preparations provide a mild and delicate cleaning action, non-irritating to the skin, have a low tendency to remove fat and a reduced tendency for stimulation of sebum secretion, the improvement wherein said preparations are specifically selected from the group consisting of a milk having the composition: (a) 1.0% carboxymethylcellulose, (b) 9.0% polyoxyethylated ricinoleic glyceride 40; (c) 1.5% polyoxyethylene cholesterol 24, and (d) the remainder water; a cream containing: (a) 2.0% sodium alginate, (b) 7.0% polyoxethylene laurylether, (c) 1.5% cetyl alcohol, (d) the remainder water; and a lotion containing: (a) 1.5% arabic gum, (b) 7.0% polyoxyethylene sorbitan monolaurate, (c) 5.0% polyethyleneglycol 400, (d) 10.0% ethyl alcohol, and (e) the remainder water.
Claim 2
Dependent Claim 175 words
In aqueous preparations for hygenic uses and, cleaning of skin, scalp and hair, selected from the group consisting of: (a) about 5 to about 10% of an emulsifying agent, and having an HLB emulsifying power of between 10 and 19; and (b) about 0.5 to about 5% of a thickening agent capable of forming gels and colloidal solutions in the presence of water, wherein the preparations provide a mild and delicate cleaning action, non-irritating to the skin, have a low tendency to remove fat and a reduced tendency for stimulation of sebum secretion, the improvement wherein said preparations are specifically selected from the group consisting of a milk having the composition: (a) 1.0% carboxymethylcellulose, (b) 9.0% polyoxyethylated ricinoleic glyceride 40; (c) 1.5% polyoxyethylene cholesterol 24, and (d) the remainder water; a cream containing: (a) 2.0% sodium alginate, (b) 7.0% polyoxethylene laurylether, (c) 1.5% cetyl alcohol, (d) the remainder water; and a lotion containing: (a) 1.5% arabic gum, (b) 7.0% polyoxyethylene sorbitan monolaurate, (c) 5.0% polyethyleneglycol 400, (d) 10.0% ethyl alcohol, and (e) the remainder water.
Claim 3
Dependent Claim 11 words
The aqueous preparations according to claim 1, additionally including preserving agents.
Claim 4
Dependent Claim 11 words
The aqueous preparations according to claim 1, additionally containing perfumery agents.
Claim 5
Dependent Claim 52 words
The aqueous preparations according to claim 1, made by a process wherein the carboxymethylcellulose and preserving agents are dissolved in water at about 75° C.; separately admixing and heating said polyoxyethylenated ricinoleic glyceride and the polyoxyethylene cholesterol; combining the resulting two phases to form a mixture; and agitating and cooling said mixture.
Claim 6
Independent Claim 88 words
A method for cleaning human skin comprising the steps of: applying to the skin, hair or scalp a substantially aqueous preparation in cream, gel, milk or lotion form containing preserving agents and consisting essentially of: about 1.0% carboxymethylcellulose about 9.0% polyoxyethylated ricinoleic glyceride; about 1.5% polyoxyethylene cholesterol 24; and the balance being water; and removing said preparation; and wherein the thickening agent combines with the emulsifying agent to produce a synergistic action improving the solubilization of fatty substances, sebum other impurities present on said skin, hair and scalp.
Claim 7
Independent Claim 88 words
A method for cleaning human skin comprising the steps of: applying to the skin, hair or scalp a substantially aqueous preparation in cream, gel, milk or lotion form containing preserving agents and consisting essentially of: about 1.0% carboxymethylcellulose about 9.0% polyoxyethylated ricinoleic glyceride; about 1.5% polyoxyethylene cholesterol 24; and the balance being water; and removing said preparation; and wherein the thickening agent combines with the emulsifying agent to produce a synergistic action improving the solubilization of fatty substances, sebum other impurities present on said skin, hair and scalp.
Claim 8
Dependent Claim 38 words
In the method of claim 5, wherein said aqueous preparation is in the form of a milk and consists of: about 1.0% carboxymethylcellulose; about 9.0% polyoxyethylated ricinoleic glyceride 40; about 1.5% polyoxyethylene chloresterol 24; and the balance water.
Claim 9
Dependent Claim 52 words
In the method of claim 5, including the steps of making said preparation by dissolving carboxymethylcellulose and preserving agents in water at about 75° C.; separately admixing and heating a polyoxyethylenated ricinoleic glyceride 40 and the polyoxyethylene chloresterol; combining the resulting two phases to form a mixture, agitating and cooling said mixture.
