  • Publication number: 20020058051
    Abstract: A skin care composition comprising. (a) a silicone-containing phase comprising cross-linked polyorganosiloxane polymer and silicone oil, wherein the composition comprises from about 0.1% to about 20% by weight of the combination of cross-linked polyorganosiloxane polymer and silicone oil, (b) from about 0.1% to about 20% by weight of an organic liquid crystal-forming amphiphilic surfactant, and (c) water; wherein the composition is in the form of an oil-in-water emulsion. The compositions of the invention provide improved skin feel, reduced greasiness/stickiness and faster absorption.

  • Patent number: 6013271
    Abstract: A skin care composition in the form of an oil-in-water dispersion which comprises from about 1% to about 60% oil phase components including from about 0.01% to about 20% by weight of a liquid, polyol carboxylic acid ester having a polyol moiety and at least 4 carboxylic acid moieties, wherein the polyol moiety is selected from the group consisting of sugars and sugar alcohols containing from about 4 to about 8 hydroxyl groups, and wherein each carboxylic acid moiety has from about 8 to about 22 carbon atoms, and wherein said liquid polyol carboxylic acid ester has a complete melting point of less than about 30.degree. C., from about 30% to about 98.89% by weight of water, and from about 0.1% to about 20% of an organic amphiphilic emulsifier material which is capable of forming liquid crystals in product or on the skin. The composition provides improved moisturization, skin feel and skin care benefits and reduced greasiness, together with excellent rub-in, absorption and stability characteristics.
