Basis for the formulation of Bacillus subtilis SPB1 biosurfactant to achieve low interfacial tension and high emulsification activities: development of a bio-based formula with potential use for personal care products
Abstract:Thanks to their multifunctional properties, such as foaming, emulsifying and skin hydrating activity, biosurfactants are potentially used in the cosmetic industry. In the present work, firstly, skin cream formulations using chemical surfactant agents and lipopeptide biosurfactants isolated from Bacillus subtilis SPB1 were investigated. The efficiency of the selected formula, containing 15% biosurfactant, was tested. Their physicochemical properties were satisfying. In fact, it shows a spreading ability of 23 m… Show more
