摘　　要：皂基复合型沐浴露兼备了表面活性剂型沐浴露和皂基型沐浴露的优点。在生产过程中,基于传统的一步皂化法易使其内包含物脂肪酸受热时挥发,对眼睛、粘膜、呼吸道具有刺激性,高温皂化反应所需时间长,能耗高。通过两步皂化法,将碱性条件下稳定的非离子表面活性剂癸基葡糖苷加入碱液,参与皂化反应。不论在小试阶段或生产阶段,均得到均匀、稳定的沐浴露膏体。结果表明,两步皂化法应用于皂基复合型沐浴露的生产是可行的,且能有效加快皂化反应速度,缩短生产时间。Soap-based composite body wash combines those advantages of both surfactant-type body wash and soap-based body wash.However,during the production of the soap-based composite body wash,traditional one-step saponification might have irritation to eyes,mucous membranes and respiratory tract,because the fatty acids therein would volatize when heated.Moreover,high-temperature saponification reaction takes long time and much energy.In this work,the body wash was manufactured via two-step saponification,in which decyl glucoside(a nonionic surfactant stable in alkaline conditions)was added in alkali liquor.The final results indicate that it is feasible to apply two-step saponification in the manufacture of soap-based composite body wash.It can effectively improve the reaction rate of saponification and save the production time.
