    • Novel organosilicon-treated cosmetic powders, for example, a pigment, extender pigment or filler are free from residual hydrogen, have a smooth feel, good skin adhesion, good color and spreadability and resistance to acids and alkalis. The treated powders are useful in cosmetics such as powder formulations, oil-in-water and water-in-oil emulsions, anhydrous make-up and lipstick. Treatment can be effected with a linear reactive alkylpolysiloxane having substitued in repeating units in the backbone of the molecule both cationic and anionic groups, for example aminoethylaminopropyl and alkoxy groups. The organosilicon compound can be adsorbed and chemically bonded to the surface of the powder by heat treatment. The alkylpolysiloxane compound can have a degree of polymerization of from 5 to 100, preferably 10-15. A process for producing the treated pigment is also disclosed as are cosmetic formulations made with the treated pigment. The inventive treatment is effective for a wide range of cosmetic powders including inorganic pigments, organic lakes and hard-to-coat powders such as mica-based powders, porous silica and the like.
    • 新型有机硅处理化妆品粉末,例如颜料,体质颜料或填充剂不含残余氢,具有光滑手感,良好的皮肤粘附性,良好的颜色和铺展性以及耐酸和耐碱性 。 经处理的粉末可用于化妆品,如粉末制剂,水包油和油包水乳液,无水化妆品和口红。 可以用分子骨架中重复单元取代阳离子和阴离子基团的直链反应性烷基聚硅氧烷,例如氨基乙基氨基丙基和烷氧基,进行处理。 可以通过热处理将有机硅化合物吸附并且化学结合到粉末的表面。 烷基聚硅氧烷化合物可具有5至100,优选10-15的聚合度。 还公开了生产经处理的颜料的方法以及用经处理的颜料制备的化妆品制剂。 本发明的处理对于各种化妆粉末是有效的,包括无机颜料,有机色淀和难涂层粉末,如云母基粉末,多孔二氧化硅等。
