The mixtures according to the invention consist essentially of fatty alcohol ethoxylate propoxylates, fatty alcohol ethoxylate mixed formals and/or end-capped fatty alcohol alkoxylates as the first main component and certain fatty alkyl polyamines as the other main component. They are particularly notable for a high foam-suppressing and disinfecting ability and are particularly suitable for aqueous cleaning liquors for the mechanical cleaning of hard surfaces.

Mixtures of alkoxylates having foam-suppressing and disinfecting action

The mixtures according to the invention essentially comprise A) at least one fatty alcohol ethoxylate-propoxylate and B) at least one fatty amine and/or fatty amine ethoxylate. They have an unexpectedly high foam inhibition capacity and are particularly suitable for aqueous cleaning liquors for mechanical cleaning of hard surfaces.
