摘要
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.关键词
