Abstract
High molecular weight protein/fatty acid condensation products obtained by reaction of one mole of a protein hydrolysate of average molecular mass 3,000 to 7,000 with 0.5 to 3, preferably 2 to 2.5, moles of a C.sub.12 -C.sub.18 -fatty acid chloride in aqueous medium at a pH of 7 to 12. These protein/fatty acid condensation products are distinguished by eliciting no mucosal irritation whatever. They are therefore outstandingly suitable as surfactants for mild washing and cleansing agents.
