It is provided cosmetics to prevent to come off and keep long. The cosmetic comprises specific polyurethane particles with a cosmetic base. The specific polyurethane particle consists of a body of the polyurethane particle and hydrophilic fine silica powders existing on the body. The body is obtained by three-dimensionally polymerizing an isocyanate-terminated urethane prepolymer with trifunctional or more functional amines. The isocyanate-terminated urethane prepolymer is obtained by reacting polyisocyanates and polyols including a poly(tetramethylene ether)glycol. The polyurethane particles are obtained by spray-drying a mixed aqueous dispersion in which the hydrophilic fine silica powders and the polyurethane spheres are dispersed in a water.本發明之課題在於提供一種防止脫妝、持妝良好之化妝料。本發明之解決手段為此化妝料係於化妝基劑中調配並含有特定之聚胺基甲酸酯粒子群。此特定之聚胺基甲酸酯粒子係由聚胺基甲酸酯粒子本體、與被覆著粒子本體表面之親水性二氧化矽微粉末群所構成。聚胺基甲酸酯粒子本體係將藉由聚異氰酸酯成分與含有聚四亞甲基二醇之多元醇成分的反應而得的異氰酸酯末端胺基甲酸乙酯預聚物,以3官能以上之多官能胺予以三維性高分子化而成者。此聚胺基甲酸酯粒子群係將使親水性二氧化矽微粉末群、與如上述般三維性高分子化而成之聚胺基甲酸酯球體群分散於水中而成的混合水性分散液,以噴霧乾燥機進行噴霧乾燥而獲得。
