The present invention provides a cosmetic composition that is stable, not sticky when used, has excellent moisture and smoothness, and maintains the effects for a long time without deterioration due to washing and/or sweating. Specifically, the present invention provides a cosmetic composition that comprises: (i) a polyalkylene oxide-modified product obtained by reacting a polyalkylene oxide compound, a diol compound, and a diisocyanate compound; and (ii) water or a lower alcohol aqueous solution, wherein the cosmetic composition comprises 0.3 mass % or more polyalkylene oxide-modified product.

Cosmetic composition

A hydrophilic thickener comprising a polymer obtainable by subjecting a water-soluble ethylenically unsaturated monomer to a reversed phase suspension polymerization in the presence of a polyoxyethylene polyoxypropylene alkyl ether; and a cosmetic composition containing the hydrophilic thickener. The hydrophilic thickener according to the present invention can be used in the fields of cosmetics such as powder foundations, liquid foundations, emulsions, lotions, liquid cosmetics, moisturizing gel, all-in-one gels, cleansing foams, hair setting agents, emollient creams; toiletries, sundries, and the like.

Hydrophilic thickener and cosmetic composition

The present invention provides a lubricating resin composition for personal care, wherein the composition not only maintains its excellent lubricity and roughness-resistant property under a wet condition even during repeated use thereof, but also represents a low swelling ratio and no slimy feeling under a wet condition. The lubricating resin composition for personal care Of the present invention comprises 100 parts by mass of a water-absorbent modified polyalkylene oxide and 25 to 500 parts by mass of a low-melting point polyamide resin.

Lubricating resin composition

The present invention provides a water-soluble polyalkylene oxide-modified product which is nonionic, has a high thickening effect and is also excellent in transparency, and an emulsion composition and a cosmetic material containing the same. More specifically, the present invention provides a water-soluble polyalkylene oxide-modified product obtained by reacting a monovalent hydrophobic alcohol, a linear diol compound, a polyalkylene oxide compound and a diisocyanate compound, and an emulsion composition and a cosmetic material containing the same.

Water-soluble polyalkylene oxide-modified product

The object of the present invention is to provide a modified polyalkylene oxide capable of yielding an aqueous solution excellent in transparency with high viscosity, even when combined with a cationic surfactant. The present invention provides a modified polyalkylene oxide obtained by reacting a polyalkylene oxide compound (A), a polyether monohydric alcohol (B), and a diisocyanate compound (C);

Modified polyalkylene oxide

Provide is a cross-linked polymer which is a polymer of a water-soluble ethylenically unsaturated monomer, the cross-linked polymer being cross-linked by a water-soluble crosslinking agent. An aqueous liquid with a pH of 6.8 to 7.0 consisting of water and 1.0% by mass of the cross-linked polymer has an equilibrium compliance at 25&#xb0; C. of 5.2&#xd7;10to 1.0&#xd7;10(1/Pa), while an aqueous liquid with a pH of 6.8 to 7.0 consisting of water and 0.2% by mass of a corresponding cross-linked polymer has a viscosity at 25&#xb0; C. of 200 mPa&#xb7;s or more.
