摘要： 系统地研究了配方组成及物化环境对烷基糖苷类乳化剂体系液晶形成的影响,探讨了可能的影响机理。配方组成主要包括4种不同种类的乳化剂、5种不同分子结构的助乳化剂、4种不同极性的油脂和4种不同分子结构的聚合物及其用量,物化环境主要包括pH及离子强度,在相同的实验条件下均质乳化获得液晶体系。实验结果表明:4种乳化剂中,花生醇葡糖苷所形成的液晶结构单元较多、尺寸较大,且结构规整;5种助乳化剂中,菊粉月桂基氨基甲酸酯可以有效促进液晶结构的形成,相对提高乳液稳定性;4种油脂中,白油所形成的液晶结构单元最多,尺寸较小且均匀;4种聚合物均可促进烷基糖苷类乳化剂液晶结构的形成,且随着聚合物质量分数的增加,液晶结构单元增多、尺寸更小且均匀;pH及离子强度对体系的液晶形成没有明显影响;然而,高离子强度(w(NaCl)>0.3%)会影响液晶乳液的稳定性。

Abstract: The influences of formulation ingredients and physicochemical environment on the formation of liquid crystals in alkyl polyglucoside (APG) systems were studied systematically.Possible mechanism of forming of liquid crystal system was explored.The formulation ingredients included four kinds of APG emulsifier,five kinds of co-emulsifier with different molecular structure,four kinds of oil with different polarity and four kinds of polymer with different molecular structure.Meanwhile,different dosages of the above mentioned raw materials were discussed.The physicochemical environment included mainly pH value and ionic strength.Emulsions with liquid crystal were obtained under same experimental conditions via homogenizing.Results showed that,within the four kinds of emulsifier,that formed with arachyl alcohol has more amount of liquid crystals with bigger size and regular structure;within the five kinds of co-emulsifier,inulin amino lauryl formate can effectively promote the formation of liquid crystal structure,and increase the emulsion stability;within the four kinds of oil,that formed with white oil has the most amount,rather smaller size and homogenous liquid crystal structure units;the four kinds of polymer may promote the formation of liquid crystal structure,while as the increase of the polymer mass fraction,the liquid crystal unit structure is smaller in size and more homogeneous;pH value and ionic strength has no obvious influence on liquid crystal status,while high ionic strength (w(NaCl)>0.3%) would reduce stability of the liquid crystal emulsion.
