Abstract
Oil-in-water microemulsion cleaning compositions comprising four principal components are described. These four components are a terpene solvent, e.g., d-limonene, an aliphatic glycol monoether co-solvent, e.g., dipropylene glycol monomethyl ether, a mixture of non-ionic surfactants selected from (1) a capped alkylphenol ethoxylate or an ethoxylated higher aliphatic alcohol, and (2) a fatty acid alkanolamide, and water. The cleaning composition may be used in concentrated form or in a diluted form. The composition may be used for cleaning soil from among others glass and metal parts.
