Abstract: The present invention provides an oil-in-water type cosmetic that is excellent in the dispersion stability of an ultraviolet scattering agent, can provide a refreshing feel and light sense of use with no stickiness to the skin, and also has a high ultraviolet-shielding effect; and a sunscreen cosmetic comprising the oil-in-water type cosmetic. The oil-in-water type cosmetic comprises: (A) an ultraviolet scattering agent; (B) a nonionic surfactant; (C) a modified polyalkylene oxide represented by formula (I) (D) an oily component; and (E) water.

Abstract: Provided is a gelled composition that exhibits, despite having 50 mass % or more of a polyhydric alcohol content, a strong thickening effect, while providing a smooth feeling of use on the skin, and even excellent dispersibility. The gelled composition of the present invention contains (A) a polymer of an ethylenically unsaturated carboxylic acid monomer crosslinked with a water-soluble crosslinking agent, (B) a polyhydric alcohol, and (C) water, wherein component (A) is present in an amount of 0.1 to 5 mass %, component (B) is present in an amount of 50 to 95 mass %, and component (C) is present in an amount of 1 to 10 mass %.

Abstract: 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° C. of 5.2×10?4 to 1.0×10?1 (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° C. of 200 mPa·s or more.

Abstract: An object of the present invention is to provide a gel-like cosmetic material the viscosity of which is not easily reduced even in the presence of an electrolyte, the cosmetic material ensuring an unconventional jelly-like feel when being applied to the skin, and a smooth sensation after being applied to the skin. The present invention provides a gel-like composition comprising 0.3 to 3 mass % of an alkyl-modified carboxyl-group-containing water-soluble polymer, 3 to 20 mass % of a polyhydric alcohol, and 0.25 to 5 mass % of an inorganic salt, the alkyl-modified carboxyl-group-containing water-soluble polymer being (i) a polymer obtained by polymerizing a (meth)acrylic acid and a C18-24 alkyl-containing (meth)acrylic acid alkyl ester, or (ii) a polymer obtained by polymerizing a (meta)acrylic acid, a C18-24 alkyl-containing (meth)acrylic acid alkyl ester, and a compound having two or more ethylenically unsaturated groups.

Abstract: The present invention provides an HASE polymer which produces a high thickening effect in a small amount at low costs. More specifically, the present invention provides a (meth) acrylic acid-based copolymer obtained by polymerizing (meth) acrylic acid, an alkyl (meth)acrylate with an alkyl group of having 1 to 4 carbon atoms, and a (polyoxyethylene stearyl ether) ester of (meth) acrylic acid.

Abstract: Novel compounds, 4-tert.-butyl-1,2-benzenedithiol and bis(4-tert.-butyl-1,2-dithiophenolate) metal complexes having the general formula of ##STR1## wherein M represents a trivalent transition metal, and A represents a quarternary ammonium are provided.The novel benzenedithiol is produced by reacting 4-tert.-butylbenzenethiol or di(4-tert.-butylphenyl)disulfide with sulfur monochloride in the presence of iodine or a Lewis acid in a solvent, and then reducing the resultant product with a metal selected from the group consisting of zinc, tin, iron and aluminum in the presence of an acid.The novel Cu, Co and Ni complexes are produced by reacting the benzenedithiol with a salt of the corresponding divalent transition metal in the presence of an alkoxide metal or a hydride metal and a quarternary ammonium salt in a solvent under an oxidative atmosphere.
