ABSTRACT:
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.
