Abstract
The anti-foaming preparations comprise aqueous formulations, which contain at least one substance, from the group of polyhydroxy compounds, non-ionic detergents and phosphoric acid esters and their salts, preferably alkyl polygluocosides, alkoxylated long-chain alcohols and an alkali salt of a phosphoric acid partial-ester. The particular advantage of said aqueous formulations is that they are stable when included in highly alkaline cleaning concentrates.
