ABSTRACT:
A free flowing aqueous defoamer comprised of alcohol, a fatty acid, a soap of a fatty acid and an anionic and/or non-ionic surfactant which prevents formation of a gelled mass of the solids and provides a free flowing dispersion of the solids in the water, with the solids contents being at least 5%, preferably at least 20%, all by weight. In a preferred embodiment, the composition includes a water soluble metal salt to render the surfaces of the solids hydrophobic. The defoamer has particular applicability for defoaming paper machine stock.
