Biosurfactants are becoming more commonplace in pharmaceuticals, vaccines and other forms of medicines. With the biobased economy growing substantially and pressure to reduce reliance on palm and crude oil derived materials, it is vital that the Home and Personal Care industry develops frameworks for deploying sustainably sourced alternative materials. Biosurfactants tend to be very similar to nonionic and mild anionic surfactants but with significantly higher molecular weights, generally more than double that of the most commonly used conventional surfactants. By means of studying the structure of the adsorbed layer of biosurfactant conventional surfactant mixtures, in this case using Saponins we hope to gain understanding which can aid in the expansion of the use of these materials towards commodity products.
