Partitioning of six printing ink solvents in high fat cookies and in the major fatty components, soybean oil and chocolate liquor, was studied by headspace analyses by gas chromatography. Solvents were ethyl acetate, hexane, isopropanol, methyl cellosolve, methyl ethyl ketone and toluene. The order of solvent partition coefficient magnitude between the target materials and air was soybean oil > chocolate liquor > cookies. Partition coefficients over the range from 1 to 200 ppm solvent in the target materials were constant, although some evidence of deviation at the lowest concentrations was found.
