Aqueous degreaser compositions are formulated in the form of stable emulsions containing at least one sparingly water soluble organic solvent having specified compositional characteristics, a viscosifying thickener and water. The viscosifying thickener is present in an amount such that when the mixture of the organic solvent and thickener are subjected to sufficiently energetic mixing and/or shear conditions, the initially formed, unstable 2-phase agglomerate is transformed into a uniformly opaic, stable emulsion having a viscosity of at least 500 centipoise and a droplet size of approximately 0.1 to 3 millimicrons. The compositions so formulated exhibit excellent stability and degreasing efficacies.

Aqueous degreaser emulsion compositions

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.

Aqueous cleaner/degreaser microemulsion compositions

Improved stable, aqueous cleaner/degreaser compositions formulated in the form of totally water soluble solutions comprise:

Aqueous cleaner/degreaser compositions

Stable, aqueous degreaser compositions are formulated in the form of totally water soluble solutions containing at least one sparingly soluble organic solvent having specified compositional characteristics, a solubilizing coupler and water. The solubilizing coupler has a surface tension in excess of approximately 45 dynes/cm (at concentrations of approximately 0.01-1.0%) and is present in an amount not substantially exceeding twenty-five percent more than the minmum amount required to completely solubilize the organic solvent. The compositions so formulated exhibit markedly improved degreasing efficacy.
