The second generation of synthetic biosurfactants was more biodegradable, but it was less gentle to the skin, and besides it was made from petrochemical raw materials. All of these surfactants left much to be desired. If one attribute of the surfactant was improved, in many cases another attribute would become worse. It was a zero-sum game.

Abstract. Biosurfactants are active compounds that are produced at the microbial cell surface or excreted, and reduce surface and interfacial tension. Microbial surfactants offer several advantages over synthetic ones, such as low toxicity and high biodegradability, and remain active at extreme pH and salinity.
