Two-part cosmetic product with swelling effect to biological surfaces

摘要

The invention relates to a two part cosmetic composition for application to a biological surface to impart a swelling effect comprising a siloxane polymer with at least two hydroxy-functionalized terminal groups or hydroxy-functionalized side chains and/or a polyol with at least two hydroxyl groups, a hydrosiloxane with at least two Si—H units and a catalyst, wherein in one part of the composition the siloxan polymer and/or the polyol and the catalyst or the hydrosiloxane are contained and in the other part of the composition the hydrosiloxane or the catalyst are contained and wherein said catalyst catalyzes in-situ cross-linking of the siloxane polymer or polyol and the hydrosiloxane by dehydrogenative coupling to form a foamed elastomeric transfer resistant film after combination of the two parts.

主权项

1. A two-part cosmetic composition for providing an expanded elastomeric transfer resistant film on a biological surface to impart a swelling effect, the two-part cosmetic composition comprising:
one or more siloxane polymers; a hydrosiloxane with at least two Si—H units; and a catalyst, wherein, with the exception of the hydrosiloxane, all of the siloxane polymers present in the two-part cosmetic composition have at least two hydroxy-functionalized terminal groups, wherein the hydrosiloxane and the catalyst are separate from each other in a first part and a second part of the cosmetic composition, wherein the one or more siloxane polymers are contained in an amount of 1 to 60 percent by weight, based on total weight of the siloxane polymer containing part, wherein the catalyst is contained in an amount of 0.001 to 3 percent by weight based on total weight of the catalyst containing part, wherein the hydrosiloxane is contained in an amount of 0.1 to 50 percent by weight based on total weight of the hydrosiloxane containing part and comprises at least dimethiconol; wherein the catalyst catalyzes, in-situ, a dehyrogenative coupling reaction that, upon combining the first part and the second part, crosslinks at least one component of the two-part cosmetic composition and the hydrosiloxane to form the expanded elastomeric transfer resistant film; and wherein the composition further comprises hydrogenated caster oil dimer dilinoleate.
