The present invention is a method for producing a vesicle composition having an aqueous phase as a continuous phase, the method including a step of dissolving an oil phase containing component (A) a branched fatty acid having a predetermined structure; component (B) a tertiary amine having a predetermined structure; and component (C) an organic acid having 1 to 10 carbon atoms at a temperature that is equal to or higher than a melting point of the oil phase, and a step of carrying out mixing while adding the aqueous phase to the oil phase which is dissolved.

Method for producing a vesicle composition

A cosmetic composition having excellent application feeling and transparency while maintaining covering power which includes (a) composite particles obtained by allowing at least two kinds of particles having different shapes and particle diameters to contact with at least one polymer compound selected from the group consisting of fluorinated polymer compounds, silicone polymer compounds, and mixture thereof, in the presence of supercritical carbon dioxide, and (b) a cosmetic component.

Cosmetic composition

A process for preparing a solid particles-containing emulsion comprising mixing an oil droplets-in-water emulsion with lipophilic solid particles or a dispersion thereof, thereby allowing to include the lipophilic solid particles in the oil droplets. The solid particles-containing emulsion can be suitably used in paints, inks for ink jet printers, fiber-treated agents, coating materials, adhesives, skin cosmetics, hair cosmetics, and the like.
