A solubilized cosmetic composition containing an ingredient which is difficult to be dissolved in water, an alkyl-modified carboxyvinyl polymer and a hydroxyalkylated cyclodextrin so as to solubilize the ingredient difficult to be dissolved in water and in particular substantially not containing a surfactant.

Solubilized cosmetic composition with a pharmaceutical or cosmetic agent, a methacrylate copolymer and a cyclodextrin

A cholesterol ester clathrate comprising a cholesterol ester included in a hydroxyalkylated cyclodextrin; a hydrous composition comprising a hydroxyalkylated cyclodextrin, a cholesterol ester and water; a hydrous composition comprising a hydroxyalkylated cyclodextrin, a cholesterol ester, a hydrous stabilizer, and water; a hydrous composition comprising a hydroxyalkylated cyclodextrin, a cholesterol ester, a clay mineral, and water; cosmetics containing these hydrous compositions; and process for the preparation thereof. The clathrate exhibits an emulsifying effect in itself. Further, the hydrous compositions are excellent in water-holding capacity and are improved in hydration properties and separation stability at a high temperature.

Cholesterol ester clathrate, water-holding composition, hydrous compositions, cosmetics containing the same, and process for the preparation thereof

An oil-in-water emulsified composition comprising an a .alpha.-monoalkyl glyceryl ether, a wax, and a silicone oil: wherein the amount of the silicone oil is not less than 10 wt % with respect to an oil phase except the a .alpha.-monoalkyl glyceryl ether and the wax, this composition displays excellent emulsion stability and feeling of use.

External preparation for skin containing a low-molecular-weight betaine

This invention relates to an oil-in-water-in-oil (O/W/O) type multiple emulsion which contains an inner oil phase, a water phase, and an outer oil phase. The inner oil phase is first dispersed in water to form an oil-in-water (O/W) emulsion. Then, the O/W emulsion is further dispersed in the outer oil phase to form the O/W/O type multiple emulsion. The outer oil phase contains an organophilic clay mineral, which can effectively prevent the inter-mixing of the inner oil phase with the outer oil phase, thus, producing an O/W/O type multiple emulsion with excellent storage stability. Upon the using of an oil-soluble compound in the inner oil phase, this multiple emulsion system can prevent the oil-soluble compound from being oxidized. In addition, since different kinds of oils can be selected for the making of the inner and outer oil phases, respectively, the O/W/O type multiple emulsion system allows one to present two different kinds of oils, which have different properties independent from each other, in one emulsion system.
