长链烷基改性有机硅聚醚共聚物的合成和应用性能研究

Synthesis and application performance of long chain alkyl modified organosilicon polyether copolymer

采用侧链含氢硅油、1-癸烯和烯丙基聚醚为主要原料通过硅氢加成反应,制备了一种长链烷基改性有机硅聚醚共聚物(PMGC)。利用IR和~1H NMR对产物的结构进行表征,并研究了含氢硅油的含氢量、黏度及1-癸烯与烯丙基聚醚的摩尔比对产品乳化能力、油脂兼容性及配方肤感的影响。研究表明,当含氢硅油的含氢量为0.4%,黏度为100 mPa·s,n(1-癸烯)∶n(烯丙基聚醚)=3∶1时,其乳化能力和油脂兼容性较佳,将其应用于BB霜配方中,滑感和滋润感较优。

A long chain alkyl modified organosilicon polyether copolymer （PMGC） was prepared from side chain hydrogen containing silicone oil, 1 - decene and allyl polyether as main raw material by siloxane addition reaction. The structure of the product was characterized by IR and 1H NMR. The effects of hydrogen content and viscosity of the hydrogen containing silicone oil as well as 1 - decene and allyl polyether molar ratio on the emulsifying ability, oil compatibility and formula skin feeling of the product were studied. Research shows that when the hydrogen containing silicone oil contains 0. 4% hydrogen, the viscosity is 100 mPa · s, and n（ 1 - decene） ： n（ allyl polyether） = 3： 1, the emulsifying ability and the compatibility with oil are both best. If it is applied in the BB cream formula, that cream will have optimal moisture and smooth sense.
