Cosmetic compositions capable of forming a multilayer structure after application to a keratinous material are provided, as well as methods of applying such compositions to a keratinous material.

A method for producing a powder solid composition including a base containing non-volatile liquid oil, the method includes: blending wax in a powder form into the base; dispersing the base in a solvent; volatilizing the solvent at a first temperature where the wax does not dissolve; and heating the base at a second temperature where the wax dissolves, wherein a blending amount of the non-volatile liquid oil is 15% by mass or more and 40% by mass or less with respect to the base.

The present specification discloses compositions comprising one or more encapsulates comprising one or more agents and methods and uses for the disclosed agents. A composition disclosed herein can be incorporated into a body wash, an after shower body lotion, a shampoo, a conditioner, a soap, a gel, a hand sanitizer, a cream, a spray, a mouse, a lotion, an ointment, a make-up product, a lip balm, a hair spray product, an arachnid/insect repellent or a medicinal product.

Provided are: a core-corona polymer particle excellent in emulsion stability and feeling of use, and a raw material for a cosmetic and an oil-in-water emulsion cosmetic comprising the particle. The present invention provides a core-corona polymer particle obtained by radical-polymerizing a polyethylene oxide macromonomer represented by the formula (1) and one or two or more of hydrophobic monomers represented by the formulas (2) and (3) under the following conditions (A) to (D).

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.

A cosmetic product includes an O/W emulsion of a crosslinked silicone obtained from radical polymerization under emulsion polymerization reaction condition of at least one polyorganosiloxane having at least two aliphatic unsaturated carbon-carbon bonds, and optionally an organohydrogenpolysiloxane, in the presence of a polyether-modified polysiloxane. It is used in a making-up method.
