Cosmeceutical Applications of Biosurfactants

The pursuit of wellbeing, beauty and rejuvenation, which are widely valued in contemporary society, has made cosmetic products essential to the daily lives of people. Every day, new toiletries, perfumes, makeup, skin care and hair care products appear, many of which have natural active ingredients and have been formulated without the use of animal testing, which is a trend that pleases today's consumers. Biosurfactants are natural compounds with potential applications in cosmetic formulations due to their antimicrobial, antioxidant, anti‐wrinkle, emulsifying, wetting and surface activities, which are necessary features in the composition of these products. This chapter addresses possible applications of biosurfactants in cosmetics, taking into account physicochemical, biotechnological and sustainable aspects.
