The test materials were applied to one ear canal of rabbits for 6 weekdays for 2 weeks. The results were as follows: l. Among the 14 cosmetic ingredients, no comedogenicity was shown in propylene glycol and petrolatum, mild comedogencity in squalene, acetylated lanolin, polyethylene glycol, cetyl aIcohol and Tween 80. Propylene glycol, sodium lauryl sulfate and oleic acid showed moderate comedogenicity. Severe comedogenicity was observed in myristyl myristate, isopropyl myristate, butyl stearate and myristyl lactate. 2. Moderate to severe comedogenicity was shown in olive oil, sesame oil and corn oil and moderate comedogenicity in sulfur (8%) and betamethasone dipropionate (0.06%) R.

Sensitivity to mercury appears to be not uncommon and perhaps the commonest contact with mercury in the general population is by amalgam dental restorations. Recently, we have experienced 2 cases of mercury dermatitis following amalgam dental restorations which were confirmed by the patch test. We report our cases with the patch test results and review the literatue on previous reports.
