Abstract
Defoaming agents for substantially surfactant-free detergents consisting of from about 0.05 to 25 parts by weight of pyrogenic, hydrophobized silica and from about 1 to 30 parts by weight of either a paraffin wax or mixture of paraffin waxes, both of which are solid at room temperature, i.e., the wax or mixture of waxes has a solidification point ranging from about 35.degree. to 120.degree. C. The defoaming agents may be liquid dispersions of the silica and paraffin wax in about 70 to 96 parts by weight of either branched primary alcohols (C.sub.18 -C.sub.30), preferably Guerbet alcohols, or mineral oils. The defoaming agents may also be solid compositions, wherein the paraffin wax and silica are deposited on solid carriers.
