Abstract

Low-foaming, liquid or pulverulent machine detergents today consist, in the surfactant portion, mainly of surfactants based on petrochemicals; the biodegradability and ecotoxicity frequently does not reach the level of surfactants based on natural materials. Accordingly, a surfactant combination for low-foaming machine detergents is proposed, which is predominantly prepared from renewable raw materials; washing results and biodegradability are excellent. The surfactant portion of these machine detergents consists of fatty alcohol ethoxylates, soaps and alkyl polyglycosides which consist at least of a mixture of alkylglycosides of varying chain length and varying degrees of glycosylation.
