Molecular Level Interaction of Surfactant with Skin Surface
Molecular Level Interaction of Surfactant with Skin Surface
Our lab is interested in the effect of surfactant on lubrication, hydration, and friction at the skin stratum corneum surface.
We hypothesize molecular interaction between surfactant and lipid or surface protein affects how we 'feel' the skin at different time periods of applying personal care products.
We investigate the effect using NMR and X-ray & neutron scattering with a skin stratum corneum mimic system that we created.
