Özet
Keratin-surfactant interactions at the air/solution interface may be indicative for skin irritation by surfactants. In this study pure keratin was extracted from chicken feathers as described by Schrooyen at al. [1,2] and the adsorption properties of biologically produced rhamnolipids (RL) and sodium dodecyl sulfate (SDS) mixed with keratin molecules were investigated by surface tension measurements. Keratin was added in three specific amounts to RL and SDS aqueous solutions of varying concentrations, respectively, and keratin-RL and keratin-SDS interactions were investigated at pH 6.2 and 5.0.
