    • An aqueous emulsion comprises as the disperse phase obtained by emulsifying a mixture consisting of (A) a linear organosilicon polymer whose main chain is composed of diorganosiloxane units and alkylene units and (B) an oil that is liquid at room temperature. The emulsion can be produced by emulsifying a mixture of (a) a diorganopolysiloxane having silicon-bonded hydrogen atoms at the two ends of the molecular chain, (b) a diolefin or diorganopolysiloxane having silicon-bonded alkenyl groups at the two ends of the molecular chain, and (c) an oil that is liquid at room temperature and does not contain hydrosilation-reactive groups, in water, and, in this state, component (a) and component (b) are addition-polymerized using (d) a hydrosilation reaction catalyst. Cosmetic materials incorporating such aqueous emulsions possess excellent lubricating properties, good dispersibility, and adherence; a method of preparation of the emulsion; and skin and hair cosmetic materials prepared from the emulsion with excellent sensation of smoothness and moistness to the touch.
    • 水乳液包含通过乳化由(A)主链由二有机硅氧烷单元和亚烷基单元构成的直链有机硅聚合物和(B)在室温下为液体的油的混合物而获得的分散相。 乳液可以通过在(a)在分子链的两端具有与硅键合的氢原子的二有机聚硅氧烷的混合物(b)在分子的两端具有硅键合的烯基的二烯烃或二有机聚硅氧烷, 链和(c)在室温下为液体并且在水中不含硅氢化反应性基团的油,并且在该状态下,组分(a)和组分(b))使用(d)a 硅氢化反应催化剂。 掺入这种水性乳液的化妆品具有优异的润滑性能,良好的分散性和粘附性; 乳液的制备方法; 并且由乳液制备的皮肤和头发化妆品具有优异的光滑感和湿润感。

    • Spherical crosslinked organic particles exhibit a good dispersibility in thermoplastic resins, thermosetting resins, paints, coatings, cosmetics, rubbers, and toners and carriers employed in electrostatic development. Highly efficient methods for preparing these crosslinked organic particles are provided. Suspensions of crosslinked organic particles have excellent handling properties, and are highly blendable with other components. Highly efficient methods for preparing these suspensions are also provided. The spherical crosslinked organic particles have an average particle size of 0.1-500 &mgr;m, and can be prepared by emulsifying in water using an emulsifying agent, a fluid composition containing (A) an organic compound that has at least 2 aliphatically unsaturated bonds in each molecule, (B) a silicon-containing organic compound that has at least 2 silicon-bonded hydrogen atoms in each molecule, (C) an hydrosilylation reaction catalyst, crosslinking the fluid composition by carrying out an hydrosilylation reaction, and thereafter removing water.
