Abstract: A transparent liquid composition that does not substantially contain ethyl alcohol, contains water as the main solvent, and has a high concentration of perfume is provided.
The transparent liquid composition comprises: (a) 3-20% by mass of a perfume component; (b) a hydrogenated castor oil to which 30-60 moles of polyoxyethylene is added; (c) an alkanol obtained by addition polymerization of 20-30 moles of polyoxyprolylene and 20-30 moles of polyoxyethylene; (d) one type or more of a surfactant having an Inorganic-value/Organic-value of 0.70-1.20; and (e) 40% by mass or greater of an aqueous component other than ethyl alcohol, wherein the blending ratio (d/(b+c)) of the component (d) to the sum of the blending amounts of the components (b) and (c) is 0.03-0.60, and ethyl alcohol is not substantially contained.

Abstract: The purpose of the present invention is to provide a water-in-oil type emulsion cosmetic that has a replenishing and smooth feel-of-use, that, once applied, forms a uniform coating, and that can minimize the appearance of skin roughness such as pores while covering discoloration such as spots and freckles, but that does not give an impression of a thick coating. The present invention provides a water-in-oil type emulsion cosmetic characterized by containing (A) 0.1-20 mass % of metallic soap-treated powder, and (B) a water-absorptive polymer having 0.01-2 mass % of a carboxyl group. The (B) water-absorptive polymer having a carboxyl group of this cosmetic preferably can absorb 10-1,000 times its own weight.

Abstract: Provided are: a core-corona polymer particle excellent in emulsion stability and feeling of use, and a raw material for a cosmetic and an oil-in-water emulsion cosmetic comprising the particle. Certain embodiments of the present invention provides a core-corona polymer particle obtained by radical-polymerizing a polyethylene oxide macromonomer represented by formula (1) and one or two or more of hydrophobic monomers represented by formulas (2) and (3) under conditions (A) to (D).

Abstract: A method of emulsification of an oil phase in an aqueous continuous phase, by dispersing core-corona microparticles into the aqueous phase, adding the oil phase, and applying shearing force for a time sufficient to emulsify the resulting mixture. The core-corona microparticles are obtained by radical co-polymerization of a polyethylene oxide macromonomer with at least one hydrophobic acrylate monomer and at least one hydrophobic acrylamide monomer.
