Why biosurfactants are becoming key ingredients

Dominic Büning of Sasol Chemicals explains the challenges and opportunities of developing and commercializing multifunctional biosurfactants, which perform in various personal care applications, for a mass market adoption of technology

Surfactants play a critical role in the personal care industry. They act as cleansing agents, dispersants, thickening agents, emulsifiers, foaming agents, solubilizers, wetting agents and more. 

For example, surfactants are used as emulsifiers within many daily leave-on products like creams, lotions and sunscreens, where they stabilize two or multiphase systems of immiscible liquids. As key ingredients in every rinse-off formulation, such as facial cleansers, shampoos and shower gels, surfactants are used to cleanse the hair, scalp and skin effectively. 

Thus, these ingredients significantly contribute to our daily hygiene routine. Furthermore, they are also known for their encapsulating properties for other waterinsoluble ingredients, such as essential oils and perfumes.
