发明名称 VISCOELASTIC ELASTOMER GEL COMPOSITIONS
摘要 A composite article, which may be beneficially applied to the skin, includes a thermoplastic gelatinous elastomer composition, which is formed into a composite by heat with a substrate material. The gelatinous elastomer includes at least one hydrogenated styrene/isoprene/butadiene block copolymers and at least one polymer or copolymer of the group poly(styrene-butadiene-styrene), poly(styrene-butadiene), poly(styrene-isoprene-styrene), poly(styrene-isoprene), poly(styrene-ethylene-propylene), poly(styrene-ethylene-propylene-styrene), poly(styrene-ethylene-butylene-styrene) or poly(styrene-ethylene-butylene). The thermoplastic gelatinous elastomer composition further includes a non-oil plasticizer, which may be a specialty ester, an animal-derived non-oil material for imparting an esthetic property and emolliency to a cosmetic formulation, or a combination thereof. The specialty esters preferably include long-chain fatty acids estified with long-chain alcohols and gycols. The animal-derived non-oil material may include lanolin, a derivative of lanolin, squalene, a cholesterol ester or a combination thereof. The thermoplastic gelatinous elastomer composition avoids the use of plasticized oil.
