High purity oxyalkylene-modified organopolysiloxanes |
摘要 |
This invention relates to a method of making high purity oxyalkylene-modified organopolysiloxanes comprising reacting a mixture comprising a vinyloxy polyoxyalkylene compound, an organohydrogensiloxane compound and a platinum group metal-containing catalyst. The resulting oxyalkylene-modified organopolysiloxanes are free from unwanted odor and do not contain excess polyoxyalkylene compound since the vinyloxy polyoxyalkylene compounds are not prone to isomerization during the reaction. The oxyalkylene-modified organopolysiloxanes of this invention are particularly useful in hair care formulations, skin care formulations, cosmetics, silicone emulsions and in polyurethane foams. |
