European Scientific Committee Not Budging On Recommended MI Restrictions

The Scientific Committee on Consumer Safety is not swayed by Cosmetic Europe's updated data submission suggesting that methylisothiazolinone can be safely used to preserve cosmetic products in concentrations as high as 100 ppm, taking issue with industry's Quantitative Risk Assessment model for dermal sensitization and tests cited in the trade group's calculations. The committee stands by its position that MI is unsafe for use in leave-on cosmetics and should be restricted to 15 ppm in rinse-off products.
