The present invention provides a self tanning cosmetic containing 0.2-20.0 mass % of dihydroxyacetone and 0.1-10.0 mass % of an inorganic pigment powder whose surface is treated with silica coating followed by a hydrophobing treatment. The present invention provides a cosmetic that has superior storage stability, is free of discoloration and odor generation, and achieves both the decorative effect of the pigment immediately following application and the long term dyeing effect of dihydroxyacetone.

Self-tanning cosmetic

The present invention is an emulsion-type pack cosmetic containing polyvinyl alcohol, oil, and water which characteristically contains the oil in the amount of 20-80 wt % or 15-50 wt % of the total emulsion-type pack cosmetic. A fast-drying peel-off type pack cosmetic with a short drying time and superior usability can be provided.

Gelling agent and gel compositions

In order to provide a liquid crystal composition and a cosmetic preparation, which is favorable in adaptation to skin and gives smooth feeling in case of using as a skin care product, and which is favorable in adaptation to makeup and has high makeup removing effect in case of using as a make-up remover, and which is favorable in adaptation to hair and has favorable feeling of use to provide glossiness to hair in case of using as a hair care product, a cosmetic preparation of the present invention comprises (A) 10 to 60 wt % of a nonionic surfactant, (B) 1 to 50 wt % in all of one or more of a water-soluble substance having a hydroxyl group, (C) 1 to 70 wt % of a silicone oil, and (D) 10 to 60 wt % of water and has a liquid crystal phase and/or an isotropic surfactant continuous phase.

Liquid crystal composition and cosmetic preparation

A copolymer having silyl groups with at least one reactive functional group bonded thereto. The copolymer comprises a monomer (A) shown by the following Formula (I):

Copolymer containing reactive silyl groups, composition containing the same and method of treatment with the same

O/W/O type multiphase emulsion

A W/O type emulsified composition comprising an oil phase containing ethyl cellulose and a solvent capable of swelling ethyl cellulose and a water phase containing a water soluble polymer(s) emulsified as a water-in-oil type (W/O type) emulsion. A W/O type emulsified composition comprising an oil phase containing ethyl cellulose and a solvent capable of swelling ethyl cellulose and a water phase containing a polyion complex comprising cationized cellulose and sodium hyaluronate emulsified as a water-in-oil type (W/O type) emulsion.

W/O type emulsified composition and cosmetic

An emulsion for hair treatment is provided which is characterized by the following: the formulation (I) is composed of a W/O type emulsion, which allows the main agent to be stable, and contains preferably an oil soluble polymer compound for the emulsifier; the formulation (I), upon being mixed with formulation (II), can easily undergo demulsification and a phase inversion into an O/W type emulsion; and the emulsion has adequate viscosity to prevent dripping from the hair and a superior dyeing capability. Also, 2-formulation type oxidation hair dye with an excellent hair dyeing effect is provided by adding isostearyl alcohol.

Emulsion for hair treatment

To provide a base suitable for a controlled release preparation and the controlled release preparation. A bioactive substance(s) is introduced in a poly-ion complex of hyaluronic acid and a cationic polyacrylic acid derivative(s).
