to the isoparaffinic hydrocarbons low odor petroleum solvent having a boiling range of 195 u00b0 c to 250 u00b0 c kerosene and d limonene also are acceptable from an odor standpoint the isoparaffinic solvents are preferred as these materials are low odor however if odor is not a consideration substantially any of the above solvents can be utilised the compositions of the present invention also include an emulsifier for example one or more surfactants selected from anionic nonionic cationic zwitterionic and amphoteric surfactants one preferred selection comprises those disclosed in u s pat no 4 438 009 the first component of such a suitable nonionic surfactant mixture may be a sorbitan surfactant such as sorbitan monolaurate sorbitan mono oleate sorbitan trioleate and mixtures thereof the second component of the nonionic mixture includes the following classes of nonionic surfactants the ethoxylated nonylphenols such as the surfonic n series available from jefferson chemical the ethoxylated octylphenols including the triton x series available from rohm amp haas the ethoxylated secondary alcohols such as tergitol series available from union carbide the ethoxylated primary alcohol series such as the neodols available from shell chemical the polymeric ethylene oxides such as the pluronics available from b a s f wyandotte and the ethylene oxide propylene oxide block copolymers such as the plurafacs available from b a s f wyandotte the preferred nonionic surfactants recited in u s pat no 4 438 009 are.
