Liquid defoamer and defoaming process

Claim 1

A pumpable free flowing aqueous defoaming composition which can be stored in a ready to use form, comprising: (a) water; (b) at least one solid alcohol having from 14 to 28 carbon atoms; (c) at least one solid fatty acid; (d) at least one soap of a solid fatty acid, said components (b), (c) and (d) being present in the water in an effective defoaming amount and to provide a dispersed solids content in the water of at least 5%; (e) a surfactant comprised of at least one member selected from the group consisting of non-ionic surfactants and anionic surfactants selected from the group consisting of: alcohol sulfates alkaryl sulfonates ethoxylated alcohol sulfates sulfates and sulfonates of ethoxylated alkyl phenols sulfates of fatty esters sulfates and sulfonates of alkyl phenols sulfonates of condensed naphthalenes sulfonates of naphthalene sodium derivatives of sulfo-succinates alkali salts of petroleum sulfonates alkali phosphate esters sulfonated alkyl esters sodium polymeric carboxylic acid which surfactant prevents formation of a gelled mass of the solids to provide a pumpable free flowing dispersion of the solids in the water, said dispersed solids having been treated with at least one water soluble salt selected from the group consisting of calcium, iron, magnesium, barium and aluminum salts to provide hydrophobic surfaces.
