There is an increased pressure towards incorporating biosustainable and biodegradable components in consumer products such as home and personal care products, cosmetics and foodstuffs. Recent neutron reflectivity studies on the highly surface active hydrophobin and modified polysorbate surfactants demonstrate some spectacular surface self-assembly and wetting properties. Exploiting these exciting properties also requires an understanding of their complementary self-assembly properties in solution, and this is the focus of this proposal.
