配方组成对烷基糖苷体系液晶形成的影响

研究了配方组成对烷基糖苷乳化体系液晶形成的影响,并针对优化体系研究了其相行为,主要研究了助乳化剂和油质原料对体系液晶形成的影响。实验结果表明,在助乳化剂与烷基糖苷的复配过程中,硬脂酰谷氨酸钠和十二烷基硫酸钠有较好的助乳化作用,且对液晶的形成影响不大。在所研究的五种油质原料中,十六～十八醇可以很好的促进液晶结构的形成;极性的PPG-15硬脂醚与十八酸不利于液晶的形成;而非极性的白油则不影响体系液晶结构的形成。同时通过对烷基糖苷-十六～十八醇-硬脂酰谷氨酸钠/去离子水相行为的研究,发现此体系在任意比例范围内都会形成液晶。

Influence of formulation ingredients on formation of liquid crystal in APG system

The influence of formulation ingredients on the formation of liquid crystal in alkyl polyglucoside(APG) system was studied.The main factors such as co-emulsifiers and oily ingredients were focused.The results showed that sodium stearoyl glutamate and sodium lauryl sulfate are good co-emulsifiers for APG and they do not effect significantly on the formation of liquid crystal.Among the five oily ingredients tested,C16~18 fatty alcohol can well facilitate the formation of liquid crystal;polar materials PPG-15 ...
