Formulation and Applications of Biodegradable Rahmnolipid and Sophorolipid Biosurfactant

The hydrophilicity /hydrophobicity of sophorolipid bio surfactants has been evaluated in this research in comparison to conventional synthetic surfactants. Microemulsions of lecithin/rhamnolipid (PMNB)/sophorolipid biosurfactant were also formulated with a range of oils (varying EACN values and oil types). Sodium dihexylsulfosuccinate (SDHS)and rhamnolipid bio surfactant are less hydrophobic than sodium b is (2-ethyl)dihexyl sulfosuccinate (SBDHS), which in turn is lesser hydrophobic than the Sophorolipid biosurfactants. Therefore sophorolipid being the hydrophobic component in lecithin/rhamnolipid/sophorolipid biosurfactant formulation. Due to no significant changes in phase behavior with isopropyl myristate with changing temperature (15, 25,45C) and electrolyte concentration (0.9%and5%w/v), it makes it accessible for cosmetic and drug delivery applications. At the same surfactant active concentrations, our biocompatible formulation has higher hexadecane detergency performance compared to any commercial liquid detergent. This paper highlights the formulation of microemulsions by mixed biosurfactant systems for a range of oils and their potential applications.
