Abstract
Abstract A detergent composition having an inverse foam to temperature relationship is disclosed, as well as a binary composition for accomplishing this relationship when added to a detergent system. The inverse foam to temperature relationship is provided by a synergistic mixture of a fatty acid having a saturated or unsaturated alkyl chain of from about 14 to 22 carbon atoms and a high molecular weight primary, secondary or tertiary amine containing between about eight and 30 carbon atoms in the alkyl chain.
