Low pH environments also play an important role in the effective stabilisation and improved performance of cationic emulsions. These are gaining market interest, due to their exceptional skin feel, their ability to improve moisturisation levels in mature skin, and their ability to form films on the skin.
Formulating with cationic emulsifiers is not complicated, since similar techniques are used in traditional nonionic emulsification. The stabilisation of cationic emulsions is further achieved by incorporating viscosity enhancers, such as fatty alcohols, fatty acids and cationic compatible polymers.
