重点讨论了层状液晶乳液体系在应用到衣物柔顺剂中时其乳液结构及油相的极性对提高挥发性物质长久保留功效的影响。采用固相微萃取和气相色谱/质谱的分析技术,测定了顶空中挥发性物质的浓度随时间的变化,结果发现由聚氧乙烯醚失水山梨醇脂肪酸酯、失水山梨醇脂肪酸酯、长链脂肪醇、油和水组成的水包油型球形洋葱状层状液晶乳液LO1相和水包油型球形洋葱状LO1与平面层状Lβ的混合两相在应用过程中能够最有效地延缓具有低极性的挥发性物质的释放平衡,相反油包水型球形洋葱状层状液晶LO2和平面层状液晶Lβ不能有效地提高挥发性物质任何阶段中在织物上的沉积和保留。
The effects of the emulsion structure and the polarity of the oil phase on the long-term retention of the volatile materials when the layered liquid crystal emulsion system is applied to the fabric softener are discussed. Solid-phase microextraction and gas chromatography / mass spectrometry were used to determine the concentration of volatile compounds in the headspace over time. As a result, it was found that polyoxyethylene sorbitan fatty acid esters, sorbitan fatty acid esters , The long-chain fatty alcohol, oil and water consisting of oil-in-water spherical onion-like liquid crystal emulsion LO1 phase and the oil-in-water spherical onion-like LO1 and lamellar Lβ mixed phase in the application process can be the most effective Retarding the release balance of volatile materials with low polarity. On the contrary, the water-in-oil spherical onion-like layered liquid crystal LO2 and the planar layered liquid crystal Lβ can not effectively improve the deposition and retention on the fabric at any stage of the volatile material.
