Definitions

the present invention relates to skin care cosmetic compositions and methods of using the same.
the present invention relates to novel clear, alcohol-free sunscreen gels and methods of use thereof.
Clear cosmetic compositions are commonly used for antiperspirants and hair gels. Such compositions typically comprise polyols and silicone emulsifiers whose refractive indices are matched to provide transparent emulsions, otherwise known as gels.
the silicone elastomers normally used do not thicken the sunscreen component sufficiently, so that additional waxes are needed.
the additional waxes destroy the clarity of the conventional clear sunscreen compositions and result in compositions that are often too thick and therefore unappealing to the consumer.
the conventional sunscreen compositions typically contain alcohols, which may cause irritation and dry the skin upon application of the sunscreen products.
the present invention at one aspect relates to a cosmetic composition
a cosmetic composition comprising at least one chemical ultra-violet (UV) light absorber, at least one solvent and at least one diphenyl silicone elastomer gellant, wherein the composition is transparent and is essentially free of alcohol.
transparent refers to a composition or material having a refractive index (RI) that matches the RI of its surroundings, i.e., such a composition or material is transparent within and relative to its functional environment.
RI refractive index
a transparent composition or material as described by the present invention exhibits a light transmission value of greater than about 70%, more preferably greater than about 75%, and will not exhibit any light scattering property.
essentially free of alcohol refers to a composition or material having an ethyl alcohol content of less than about 0.5% by total weight of the composition or material.
the present invention relates to a method of using the above- described transparent cosmetic composition for protecting skin against harmful effects of UV radiation, by applying such a transparent cosmetic composition to the skin.
a stable, alcohol-free, and transparent cosmetic composition can be formed, which is particularly useful as an aesthetically appealing clear sunscreen gel.
stable refers to a composition having sufficient physical and chemical stability so that the composition does not separate or precipitate when all of the components are added.
aesthetically appealing refers to a composition having a powdery, velvety, and silky texture upon application onto the skin.
a chemical UV light absorber is used as a first essential component of the transparent cosmetic composition of the present invention.
the chemical UV light absorber can be any suitable chemical UV light absorbers commonly used in cosmetic compositions.
suitable chemical UV light absorbers include, but are not limited to: benzophenone-3, homosalate, ethylhexyl methoxycinnamate, avobenzone, ethylhexyl salicylate and octocrylene and combinations thereof.
