Oil-free viscoelastic elastomer gels for application to human skin

摘要

A composition article, which may be applied to human, includes a non-oil thermoplastic gelatinous elastomer composition, which is formed into a composite by heating with a substrate material. The gelatinous elastomer includes a hydrogenated styrene/isoprene/butadiene block copolymer, at least one polymer or copolymer of the group poly(styrene-butadiene-styrene), poly(styrene-isoprene), 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), and a non-oil plasticizer.

1. A composite article for applying to human skin, comprising:
a thermoplastic gelatinous elastomer composition formed into a composite by heat with a substrate material, said gelatinous elastomer composition including:
a hydrogenated styrene isoprene/butadiene block copolymer;a non-oil plasticizer comprising octyldodecyl myristate and an animal-derived non-oil material for imparting an esthetic property and emolliency to a cosmetic formulation; and,a polymer or copolymer selected from the group consisting of 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, poly(styrene-ethylene-butylene) and combination thereof,said gelatinous elastomer composition having no oil-based plasticizer and having no plasticizing oil.
