摘要： Encapsulated aluminum salts are produced by combining and heating an aqueous aluminum salt selected from aluminum halohydrate, aluminum nitrohydrate and mixtures thereof; a hydrophobic liquid; and a carboxylate. The mixture is heated until substantially all of the free water has been removed. The encapsulated aluminum salts precipitate out after the removal of the water. The encapsulated aluminum salts are useful in deodorant and antiperspirant compositions.

摘要： A method for preparing organopolysiloxane bases with high levels of fillers. The present inventors have found that by mixing the components of the base at a temperature below about 60.degree. C. for a period of time sufficient to effect essentially a homogeneous blend, a base composition is formed which can be further blended with a platinum group metal-containing catalyst, an organohydrogensiloxane, and optionally an inhibitor to form a curable liquid silicone rubber (LSR) composition. The curable LSR composition has improved flow characteristics and improved shelf life when compared to similar materials where the base is prepared at temperatures above about 60.degree. C. The improved flow characteristics allows larger quantities of fillers to be incorporated into the curable LSR composition while still maintaining acceptable flow characteristics. Silicone elastomers prepared using the curable LSR compositions can have improved swell and degradation resistance to oils, lower compression set values, and improved tear, elongation, and tensile values and require no post cure. The present organopolysiloxane bases are particularly useful as a common base for forming a group of cured silicone elastomers with a range of durometers.
摘要翻译：一种制备高含量填料的有机聚硅氧烷基料的方法。本发明人已经发现，通过将碱的组分在低于约60℃的温度下混合足以实现基本均匀共混物的时间，形成基础组合物，其可以进一步与铂族金属的有机氢硅氧烷和任选的抑制剂以形成可固化液体硅橡胶（LSR）组合物。与基材在高于约60℃的温度下制备的类似材料相比，可固化的LSR组合物具有改善的流动特性和改善的保质期。改进的流动特性允许更大量的填料掺入可固化LSR组合物中同时仍保持可接受的流量特性。使用可固化的LSR组合物制备的硅氧烷弹性体可以具有改善的对油的溶胀和降解抗性，较低的压缩永久变形值和改进的撕裂，伸长率和拉伸值，并且不需要后固化。本发明的有机聚硅氧烷基料特别可用作形成具有一定范围的硬度的一组固化的硅氧烷弹性体的常用碱。

摘要： A platinum group-metal curing liquid silicone rubber compositions having improved physical properties such as tear and heat-aging, especially at durometers below about 35 and above about 65. The present inventors have unexpectedly discovered that the addition of diorganohydrogensiloxy end-blocked polydiorganosiloxanes and triorganosiloxy end-blocked polydiorganosiloxanes having a viscosity greater than about 10 Pa.cndot.s at 25.degree. C. to liquid silicone rubber compositions can provide for the described improved properties.
