Abstract: A low volatile organic component stable, aqueous cleaning/degreasing composition in the form of a macroemulsion is formulated by combining (a) a nonionic surfactant having certain specified characteristics; (b) an oligomeric or mono/polyfunctional hydrophobe having certain specified characteristics; and (c) water, the nonionic surfactant and hydrophobe being present in a weight ratio of between approximately 10:1 and 1:3 and the composition having a minimum composite score of 60% removal in the soilant marking removal test. Such compositions not only contain no or low amounts of volatile organic compounds but are environmentally safe and non-toxic and exhibit excellent cleaner/degreaser activity exceeding that exhibited by either the nonionic surfactant or hydrophobe component alone at equivalent or equal concentration.
