    • Synergistic surfactant compositions. Polysiloxane-polyoxyalkylene copolymers in which the polyether pendants bear carboxylic acid groups or salts of carboxylic acid groups are demonstrated to have synergystic interactions with anionic and cationic organic surfactants to improve the surface characteristics of a solution, requiring unexpectedly low concentrations to obtain specific surface tension values or to attain critical micelle concentrations in aqueous solutions. Compositions containing an organic surfactant and a polysiloxane-polyoxyalkylene copolymer bearing carboxyl groups are claimed. A method for modifying the surface properties of an aqueous system by employing such compositions as components of the system is also claimed.
    • 协同表面活性剂组合物。 其中聚醚吊坠具有羧酸基团或羧酸基团的聚硅氧烷 - 聚氧化烯共聚物被证明与阴离子和阳离子有机表面活性剂具有增效作用,以改善溶液的表面特性,需要意想不到的低浓度以获得比表面张力值 或在水溶液中达到临界胶束浓度。 要求保护含有有机表面活性剂和含有羧基的聚硅氧烷 - 聚氧化烯共聚物的组合物。 还要求保护通过使用这种组合物作为系统的组分来改变水性体系的表面性质的方法。
