摘要：

洁面泡沫以其使用方便、泡沫细腻绵密等优点受到消费者的青睐。文章主要以皂基体系为基础洁面泡沫配方,研究了月桂醇聚醚-6羧酸以及pH对体系的发泡力和泡沫稳定性的影响,同时研究了月桂醇聚醚-6羧酸对皂基洁面泡沫体系的使用肤感方面的影响。结果表明,在月桂酸、肉豆蔻酸和月桂醇聚醚-6羧酸总质量分数为9%,月桂酸和肉豆蔻酸质量比为2∶1条件下,月桂酸、肉豆蔻酸、月桂醇聚醚-6羧酸的质量分数分别为4%,2%和3%时,体系的发泡力和泡沫稳定性较佳;pH对体系的影响较小,在pH=9.55时,具有较佳的发泡力和泡沫稳定性;经过消费者调研,发现月桂醇聚醚-6羧酸能够明显改善皂基洁面泡沫洗后的干涩肤感,促进了皂基洁面泡沫的应用。

Abstract:

Cleansing foam is favored by consumers for its convenient use and delicate foam. Based on the soap-based system, the effect of laureth-6 carboxylic acid and pH on foaming capacity and foaming stability of the system were studied. Meanwhile, the effect of laureth-6 carboxylic acid on the skin feeling of the soap-based system was also estimated. Under the condition that the total mass fraction of fatty acid is 9%（with the mass ratio of lauric acid and myristic acid is 2∶1）, it shows that foaming capacity and foaming stability of the system are excellent when the mass fraction of lauric acid, myristic acid and laureth-6 carboxylic acid is 4%, 2% and 3% respectively. The pH value has little influence on the system, and the optimum foaming capacity and foaming stability can be reached at the pH value of 9.55. After the consumer research, it is found that lauryeth-6 carboxylic acid can significantly improve the dry skin feel of soap-based facial cleansing foam after washing, and promote the application of the soap-based cleansing foam.

Key words: laureth-6 carboxylic acid, soap system, cleansing foam
