Abstract
An auto-emulsifying cleaning composition capable of emulsifying upon contact with water, the composition in one typical embodiment comprising, based on the total weight of the composition, (a) from about 1% to about 99% by weight a blend of dibasic esters; (b) from about 1% to about 40% by weight of a blend of surfactants consisting of an organic anion neutralized with an organic cation, where either or both of the anion and the cation have surfactant properties, and the complex of which is soluble in the dibasic ester solvent blend. The blend of surfactants is typically a cationic surfactant and an anionic surfactant, which may or may not be used in conjunction with non-ionic surfactants. The dibasic esters are be derived from a blend of adipic, glutaric, and succinic diacids, and, in one particular embodiment, the blend comprises dialkyl adipate, dialkyl methylglutarate and dialkyl ethylsuccinate, wherein the alkyl groups individually comprise a C1-C12 hydrocarbon group.
