| 摘 要： | 首先将辛基酚聚氧乙烯醚(OP10)、苯乙烯基酚聚氧乙烯醚(602)和蓖麻油聚氧乙烯(40)醚(EL-40)分别与蓖麻油聚氧乙烯(20)醚(EL-20)复配制备阿维菌素水乳剂,从亲水亲油平衡(HLB)值、临界胶束浓度(cmc)、表面张力等方面分析了二元表面活性剂复配对乳液稳定性的影响;其次,在EL-40与EL-20复配基础上,将苯乙烯基酚聚氧乙烯聚氧丙烯醚(1601),嵌段共聚物(L64)和辛基酚聚氧乙烯醚磷酸酯(A)分别添加到乳液中,从粒径、表面张力和zeta电势等方面考察三元表面活性剂复配对乳液稳定性的影响.结果表明:EL-40与EL-20复配具有较低的表面张力,可制备较稳定的乳液.添加1601和L64对乳液稳定性有一定提高;而添加A大大提高了乳液的稳定性,这是由于A显著降低了液滴粒径和表面张力,增加了zeta电势.

| Abstract: | The preparation of avermyctin emulsions in water was achieved by mixing the surfactants polyoxyethylene (10) octylphenyl ether (OP10),polyoxyethylene styrenated phenol ether (602),and polyoxyethylene (40) castor oil ether (EL-40) with polyoxyethylene (20) castor oil ether (EL-20),separatively.Emulsion stability was investigated by analyzing the hydrophile-lipophile balance (HLB),critical micelle concentration (cmc),and surface tension.Then,the surfactants of polyoxyethylene polyoxypropylene styrenated pheno... |
