A body cosmetic for application to wetted skin after bathing, and the like, which provide high moisturizing effects, spread well to all over the body, and are easy to apply. An oil-in-water body cosmetic for application to wetted skin, which contains a water-soluble polymer and the following components (A) to (C):

Body cosmetics for wetted skin

The invention relates to an external skin care composition comprising a ceramide production-accelerating agent and a film-forming polymer. The external skin care composition can enhance the barrier function of the skin and has an excellent skin roughness-improving effect.

External skin care composition

An external skin-care composition comprising (A) a low-strength agar having a jelly strength of 250 g/cm,or lower as measured at an agar concentration of 1.5 wt. %; (B) a water-soluble polymer; (C) a cooling agent; and (D) water. The external skin-care composition has a high cooling effect, a feeling of coolness and excellent stability.

External skin-care composition

The present invention provides a method for producing a material dispersed with ultraviolet shielding fine particles, characterized by subjecting a starting material liquid mixture comprising particles comprising one or more inorganic substances having shielding abilities against ultraviolet light, one or more silicone dispersants selected from modified silicones and reactive silicones, and a silicone oil to a mill treatment and/or a high-pressure dispersion treatment; and ultraviolet shielding fine particles or a material dispersed therewith, characterized by being produced by the above method. Also, the present invention provides a method of producing a powdery product of ultraviolet shielding fine particles, characterized by drying the material dispersed with ultraviolet shielding fine particles obtainable by the above method. Further, the present invention provides cosmetics comprising a material dispersed with ultraviolet shielding fine particles or a powdery product of the ultraviolet shielding fine particles. The material dispersed with ultraviolet shielding fine particles of the present invention is characterized in that the ultraviolet shielding fine particles comprise particles comprising one or more inorganic substances having shielding abilities against ultraviolet light, surfaces thereof being coated with one or more silicone dispersants selected from modified silicones and reactive silicones, and that at least a part of the ultraviolet shielding fine particles is dispersed in a silicone oil as aggregated particles of the particles comprising inorganic substances.
