SOPHOROLIPIDS
Sophorolipids (SLs) are biosurfactants produced by a natural strain of yeast (Starmerella bombicola) through the fermentation of sugar and vegetable oil. SLs are a class of glycolipid that have similar structures, consisting of a hydrophilic head (sophorose) and a hydrophobic tail (fatty acids).
Besides providing detergent-related properties of extremely low CMC (35-40 ppm) and wide HLB, Sophorolipids feature enhanced anti-bacterial and mite-killing capabilities, as well as low-toxicity, biodegradability and other eco-friendly properties, making the product one of the most promising bio-based surfactants in the market.
There are two main types of Sophorolipids, i.e. the lactonic form and the acidic form. The lactonic form offers better surface tension reduction and stronger antimicrobial activity, while the acidic form provides better foaming capability and solubility.

Contact angle, θ, is a measure of wettability of a surface by a liquid. The contact angles of the fermented oils were all lower than the unfermented oils, with the fermented shea butter and fermented jojoba seed oil showing perfect wetting.
