Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 111 words
Substantially aqueous preparations for hygenic uses and, cleaning of skin, scalp and hair, 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, said preparations being selected from the group consisting of: (a) 1.0% carboxymethylcellulose, (b) 9.0% polyoxyethylated ricinoleic glyceride 40, (c) 1.5% polyoxyethylene cholesterol 24, and (d) the remainder water; (a) 2.0% sodium alginate, (b) 7.0% polyoxyethylene laurylether, (c) 1.5% cetyl alcohol, and (d) the remainder water; and (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 111 words
Substantially aqueous preparations for hygenic uses and, cleaning of skin, scalp and hair, 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, said preparations being selected from the group consisting of: (a) 1.0% carboxymethylcellulose, (b) 9.0% polyoxyethylated ricinoleic glyceride 40, (c) 1.5% polyoxyethylene cholesterol 24, and (d) the remainder water; (a) 2.0% sodium alginate, (b) 7.0% polyoxyethylene laurylether, (c) 1.5% cetyl alcohol, and (d) the remainder water; and (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 preparation according to claim 1, additionally containing perfumery agents.
Claim 4
Dependent Claim 13 words
The aqueous preparations according to claim 1, additionally including preserving agents as needed.
Claim 5
Dependent Claim 11 words
The aqueous preparations according to claim 3, additionally containing perfumery agents.
Claim 6
Independent Claim 171 words
A method of cleaning human skin, hair or scalp comprising the steps of: applying to the skin, hair or scalp a substantially aqueous preparation whose efficacy is not based on the cleaning-fat removal action of its ionic type so that the normal processes of sebum secretion are not altered, said aqueous preparation containing preserving agents and as a weight percent of the total weight of the preparation, said preparation consisting of: about 1.0% carboxymethylcellulose as a thickening agent; about 9.0% polyoxyethylated ricinoleic glyceride 40 as an emulsifying agent; about 1.5% polyoxyethylene cholesterol 24 as an emulsifying agent; and the balance water; and removing said preparation; wherein said preparation provides a mild and delicate cleaning action while lacking an irritating effect on the skin, and has a low tendency to remove fat and a reduced tendency for stimulation of sebum secretion, said thickening agent combining with said emulsifying agents to produce a synergistic action with respect to each other and with respect to the solubilization of fatty substances, sebum and other impurities.
Claim 7
Independent Claim 171 words
A method of cleaning human skin, hair or scalp comprising the steps of: applying to the skin, hair or scalp a substantially aqueous preparation whose efficacy is not based on the cleaning-fat removal action of its ionic type so that the normal processes of sebum secretion are not altered, said aqueous preparation containing preserving agents and as a weight percent of the total weight of the preparation, said preparation consisting of: about 1.0% carboxymethylcellulose as a thickening agent; about 9.0% polyoxyethylated ricinoleic glyceride 40 as an emulsifying agent; about 1.5% polyoxyethylene cholesterol 24 as an emulsifying agent; and the balance water; and removing said preparation; wherein said preparation provides a mild and delicate cleaning action while lacking an irritating effect on the skin, and has a low tendency to remove fat and a reduced tendency for stimulation of sebum secretion, said thickening agent combining with said emulsifying agents to produce a synergistic action with respect to each other and with respect to the solubilization of fatty substances, sebum and other impurities.
Claim 8
Dependent Claim 49 words
The method of claim 5, wherein said preparation is made by dissolving carboxymethylcellulose and preserving agents in water at about 75° C.; separately admixing and heating said polyoxyethylenated ricinoleic glyceride and the polyoxyethylene chloesterol; combining the resulting two phases to form a mixture; and agitating and cooling said mixture.
