摘要
本文合成了以缩水甘油乙酸酯和四氢呋喃为单休,长链脂肪醇为链转移剂的共聚物,对该共聚物进行干法醇解,制得了聚(氧四亚甲基)聚(甘油基)烷基醚类非离子型表面活性剂,记为RT_mG_n。对RT_mG_n进行了结构分析和性能研究。实验结果表明:RT_mG_n聚甘油醚类非离子型表面活性剂具有良好的化学稳定性和表面化学性质,无毒、无刺激,可作为乳化剂应用于化妆品中。
In this paper, the nonionic surfactant polyglyceryl polyoxytctrame-thylene fatty alcohol ether (RTmGn) was synthesized from fatty alcohol tetrahydrofuran and glycidic acetate.The chemical structure and degree of polymerization of RTmGn, were confirmed by IR and HNMR.The surface chermical propertier of RTmGn were determined and discussed THe chemical stabilization of RTmGn. was investigated. The dermal irritaton level of RTmGn are low.The RTmGn, as an emul-sifier can be used in cosmetics.
