Abstract: Compositions for application to skin of a subject comprising (a) an unsaturated organopolymer, (b) a hydride functionalized polysiloxane and (c) an environment-responsive agent that is capable of transporting out of the composition or facilitates out-transport of one or more beneficial agents from the composition after the composition is applied to a subject. Alternatively, the compositions comprise (a) a bifunctional organopolysiloxane polymer having one unsaturated group and one hydride and (b) the environment-responsive agent. The environment-responsive agent may be a volatile agent and the compositions can be used to create a thin film on the skin of a subject wherein the volatile agent is capable of transporting out of the film. In one embodiment, the volatile agent is transported out of the composition by convection. In one embodiment, the volatile agent is transported out of the composition by diffusion.

Abstract: To provide a second agent for a coating-type body corrective film formation agent that can shorten the cross-linking reaction time in film formation and improve the durability of the film to be obtained.
An oil-in-water composition of the present disclosure comprises a dispersion medium containing water, and oil droplets dispersed in this dispersion medium, wherein the oil droplets comprise an oil, and a catalyst that serves as a cross-linking ingredient, wherein the oil-in-water composition is used as a second agent for a coating-type body corrective film formation agent comprising a first agent comprising a cross-linking reactive ingredient that constitutes a body corrective film; and a second agent comprising a cross-linking ingredient for cross-linking the cross-linking reactive ingredient.
