Abstract
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.
