Abstract

Improved stable, aqueous cleaner/degreaser compositions formulated in the form of totally water soluble solutions comprise: (a) at least one sparingly water soluble organic solvent characterized by: (i) having a watersolubility in the range of approximately 0.2 to approximately 6 weight percent; (ii) not being a hydrocarbon or halocarbon; (iii) having one or more similar or dissimilar oxygen, nitrogen, sulfur or phosphorous containing functional groups; (iv) being a solvent for hydrophobic soilants; and (v) being present in an amount exceeding its aqueous solubility; (b) 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 exceeding approximately tenfold that required to completely solubilize the organic solvent; and (c) water. Such compositions exhibit markedly superior cleaning/degreasing efficacy over that achievable with compositions containing infinitely water soluble organic solvents such as butyl cellosolve.
