However, soap-based product appears to be not physically stable under certain circumstance. For example, product viscosity decreases with the increase of temperature but goes up when the temperature goes down. More seriously, phase separation may occur for some products with time. Many efforts have been made to improve the stability of soap-based formulations mainly focusing on 1) adjust the fatty acids ratio;2) optimize saponification level;3) addition of thickeners and surfactants. Improvements have been made upon recent reports. However, required stability of the formulations at both high and low temperature is not satisfied yet. In this work, we introduced one type of non-ionic emulsifier to the soap-based formulation, through which to regulate the microstructure. It is seen that the stability is significantly improved at both high and low temperature, and the using performance is enhanced in the meantime.展开更多
从泡沫量与结构、结膏温度、质地以及稳定性等方面,研究了4种不同乳化剂对以椰油酰甘氨酸钠为主的结晶型洁面膏的影响。结果表明,聚甘油类乳化剂Hostacerin®DGSB使配方结膏温度降低,同时配方具有更高的硬度、浓稠度以及黏性,显著...从泡沫量与结构、结膏温度、质地以及稳定性等方面,研究了4种不同乳化剂对以椰油酰甘氨酸钠为主的结晶型洁面膏的影响。结果表明,聚甘油类乳化剂Hostacerin®DGSB使配方结膏温度降低,同时配方具有更高的硬度、浓稠度以及黏性,显著提高配方的稳定性;磷酸酯类乳化剂Hostaphat®KW340D能提高洁面膏的泡沫稳定性,明显提高配方的结膏温度以及与珠光剂的相容性,也能明显提高硬度、浓稠度、黏性以及配方的稳定性。液晶型乳化剂Plantasens®Emulsifier HP 30能显著提高泡沫的细密程度与稳定性,硬度提高的同时也有比较好的铺展性;而聚醚类乳化剂Eumulgin®S21与体系的兼容性差,导致泡沫量明显减少,泡沫的稳定性也最差,虽然能提高结膏温度,但加速洁面膏的失稳过程,因此不适用于该体系。展开更多
