Abstract The submission presents a summary of the final results from 12-week inhalation toxicity studies of ISOPAR C and VARSOL 40 solvents in male and female rats. Evidence of kidney damage is reported for male rats exposed to the solvents. Both ISOPAR C and VARSOL 40 appear to produce typical toxic nephrosis (degeneration of the epithelial cells of the kidney tubules without damage to the basement membrane). Mercury, dichromate, uranium, chloroform, carbon tetrachloride, dioxane, and many other chemicals produce similar lesions in the kidney.
