Abstract
The disclosure concerns stable, aqueous cleaner/degreaser compositions formulated in the form of true microemulsions and containing a builder component. The microemulsions comprise (a) at least one sparingly water soluble organic solvent having specified characteristics including having a water solubility in the range of approximately 0.2 to approximately 6 weight percent and being present in an amount exceeding its aqueous solubility; (b) a builder; (c) a solubilizing additive consisting of from approximately 0.1 to approximately 100 weight percent of a surfactant and from 0 to approximately 99.9 weight percent of a coupler, the solubilizing additive being present in an amount not substantially exceeding the amount required to transform the combination of the organic solvent and builder from the form of a true macroemulsion to the form of a microemulsion and less than that required to form a true solution; and (d) water.
