Abstract
Substantially nonaqueous concentrates for use in preparing stable, aqueous cleaner/degreaser compositions in the form of totally water soluble solutions comprise (a) at least one sparingly water soluble organic solvent having certain defined characteristics; (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 of approximately 3% to approximately 15% by weight excess over that minimally required to form a clear solution when the concentrate is combined with water; and (c) not more than 10.0 weight percent of water; (d) the concentrate forming a barely clear, totally water soluble solution when diluted with water to produce a solution having the desired cleaning/degreasing strength.
