Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 198 words
A skin cream composition comprising an oil phase, a water phase, and an encapsulated active base; (A) said oil phase comprising, in parts by weight, 1.5-3.5 parts of an emulsifier, 1.25-2.5 parts of an emollient, 8.0-14.0 parts of a lubricant, 0.5-4.0 parts of a dispersing agent, and 0.3-2.0 parts of a non-ionic surfactant; (B) said water phase comprising, in parts by weight of up to about 5 parts of hectorite clay, 0.2-1.0 parts of a peptizer for said clay, up to 5.0 parts of a humectant, 1.2 parts of milk protein and the balance water; and (C) said encapsulated active base comprising, in parts by weight, 0.45-1.8 parts of hectorite clay, 0.05-2.0 parts of a polar group affording organic compound (1) characterized as being reactable with said hectorite clay to form water-insoluble particles having a size above colloidal dimensions when added to an aqueous colloidal solution of synthetic hectorite clay and tetrasodium pyrophosphate and (2) selected from the group consisting of a simple organic compound having at least one polar group characterized by insubstantial solubility in water at ordinary temperatures and (3) and organic hydrophilic colloid, 0.2-1 parts of a peptizer for said clay and the balance water.
Claim 2
Dependent Claim 198 words
A skin cream composition comprising an oil phase, a water phase, and an encapsulated active base; (A) said oil phase comprising, in parts by weight, 1.5-3.5 parts of an emulsifier, 1.25-2.5 parts of an emollient, 8.0-14.0 parts of a lubricant, 0.5-4.0 parts of a dispersing agent, and 0.3-2.0 parts of a non-ionic surfactant; (B) said water phase comprising, in parts by weight of up to about 5 parts of hectorite clay, 0.2-1.0 parts of a peptizer for said clay, up to 5.0 parts of a humectant, 1.2 parts of milk protein and the balance water; and (C) said encapsulated active base comprising, in parts by weight, 0.45-1.8 parts of hectorite clay, 0.05-2.0 parts of a polar group affording organic compound (1) characterized as being reactable with said hectorite clay to form water-insoluble particles having a size above colloidal dimensions when added to an aqueous colloidal solution of synthetic hectorite clay and tetrasodium pyrophosphate and (2) selected from the group consisting of a simple organic compound having at least one polar group characterized by insubstantial solubility in water at ordinary temperatures and (3) and organic hydrophilic colloid, 0.2-1 parts of a peptizer for said clay and the balance water.
Claim 3
Dependent Claim 63 words
A composition as claimed in claim 1, wherein: (A) said oil phase comprises glyceryl monostearate, cetyl alcohol, 2-ethylhexyl palmitate, isostearic acid, polyoxyethylene stearate, and sorbitan stearate; (B) said water phase comprises said hectorite clay, said peptizer, propylene glycol, triethanolamine, said milk protein, and said water; and (C) said encapsulated active base comprises said hectorite clay, hydroxyethyl cellulose, casein, said peptizer, and said water.
Claim 4
Dependent Claim 66 words
A composition as claimed in claim 2, wherein said hectorite clay is synthetic hectorite clay, said synthetic hectorite clay is present in said water phase in a gel-forming amount of up to about 5 percent by weight, said peptizer is sodium acid pyrophosphate and said sodium acid pyrophosphate is present in said water phase in an amount of about 0.2-1.0 percent by weight of said clay.
Claim 5
Dependent Claim 26 words
A composition as claimed in claim 2, wherein said clay is synthetic hectorite clay and the weight ratio of clay to hydroxyethyl cellulose is about 1-2:2-3.
