More than 80,000 people were patch tested for MDGN sensitivity from 1990 to 2000.
Zachariae and colleagues patch tested between February and August 2002, 19 (4.1%) had a positive reaction to MDGN. Seventeen positives were relevant, meaning a + 1 or greater reaction at 3 or 4 days and at 7 days after application.
Positive reactions were seen in products containing 300-400 ppm of MDGN, suggesting that the 1,000-ppm limit needs to be reevaluated.
