Abstract: An object of the present invention is to provide means for enhancing ability to solubilize a low water-soluble substance or to disperse the substance in water. The present invention provides a water-containing composition containing water; at least one polyoxyethylene-polyoxypropylene-added phytosterol or phytostanol represented by the following formula (1): [wherein R represents a phytosterol residue or a phytostanol residue; m is a number from 5 to 100; and n is a number from 5 to 100]; and at least one low water-soluble substance which is in a dissolved state.

Abstract: The present invention provides: an oil-in-water emulsion composition, into which an oil-soluble drug is stably incorporated and which is excellent in feeling during use; and a method for producing the aforementioned composition, which does not require complicated operations. An oil-in-water emulsion composition comprising; (A) a polyoxyethylene phytosterol, (B) a glycerin fatty acid diester, (C) a polyoxyethylene-polyoxypropylene random copolymer dialkyl ether, (D) an oil-soluble drug, (E) oil, and (F) water; wherein a layered gel structure composed of the components (A) and (B) is present in an emulsion particle in the emulsion composition.

Abstract: A water-in-oil type emulsion with a highly moisturizing effect on the skin has good emulsion stability and achieves a good feeling in use as a massage cream when a large amount of perfume is blended. The water-in-oil type emulsion includes the following components: (A) glyceryl monooleate, (B) a surfactant having branched chains in an alkyl group, (C) an aqueous component, (D) an oil component, and (E) a perfume component, Conditions (1) and (2) are met by the emulsion. Condition (1): the ratio of the sum of glyceryl monooleate (component (A)) and the surfactant having branched chains in an alkyl group (component (B)) with respect to a total composition is from 5 to 10% by mass. Condition (2): the ratio of perfume component (component (E)) with respect to the total composition is 0.3% by mass or more.

Abstract: The present invention was made in view of the above-described circumstances, and an object of the invention is to provide an external skin preparation having a rough skin improving effect, excellent in texture in use, especially excellent in smoothness, free of sticky feeling, and excellent in stability. Another object is to provide a skin cleanser excellent especially in usability and a cosmetic removing effect. That is, the external skin preparation of the present invention is characterized by comprising a block-type alkylene oxide derivative represented by the below-described formula (I). [formula 1] Y—[O(EO)a-(AO)b-(EO)c-R]k??(I) (In the formula, Y is the residue given by removing hydroxyl groups from a polyhydric alcohol having 3 to 6 hydroxyl groups, and k is the number of hydroxyl groups of the polyhydric alcohol. EO is an oxyethylene group, AO is an oxyalkylene group having 3 to 6 carbon atoms, and they are attached in a block-type, respectively.
