Abstract
Abstract Surface-active compositions are provided having controlled foaming properties comprising an anionic sulphonate or sulphate ester surfactant, a nonionic polyoxyalkylene ether, ester or glycol surfactant, and an anionic polyoxyalkylene phosphate ester surfactant, the polyoxyalkylene phosphate ester and the polyoxyalkylene ether, ester or glycol surfactants serving as low foaming components, and the anionic surfactant increasing the foaming properties of such mixtures in proportion to the amount present. Adjuncts such as builders can also be present. A process for controlling the foaming properties of anionic sulphate or sulphonate ester surfactants and nonionic polyoxyalkylene ether, ester or glycol surfactants is provided, by combining therewith, in selected amounts, an anionic polyoxyalkylene phosphate ester surfactant to give any desired controlled low to high foaming properties.
