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
