Abstract

The plant-oil derived biosurfactant HeBra® shows a high surface activity combined with a versatile aggregation behavior. The hydrophilic protein head groups provide an excellent water solubility that still enables micelle formation due to the hydrophobic interactions of the fatty acid chains. The observed low CMC of 1 g L-1 allows an efficient utilization in different application fields already at very low concentrations. The mixture of low and high molecular weight components provides highly dynamic behavior during foam formation or dispersion processes combined with the formation of large and stable structures in solutions and at surfaces.

Keywords: Adsorption; Biopolymer; Biopolymer application; Light scattering; Physico-chemical properties; Surfactant.
