Xylose Based Biosurfactants. Obtention and Physicochemical Properties

Biosurfactants from sugars are considered as good emulsifiers. Surface properties of an homologous serie of  products from xylose were determined such as hydrophilic-lipophilic balance, critical micelar concentration, foaming and emulsifying ability. Obtained surface tension values are between 25 mN.m^-1 for and 47,17 mN.m^-1. The surface parameters results revealed that the prepared compounds have a good surface activity. These bio-surfactants display good emulsifying and foaming abilities.
