Is Methylchloroisothiazolinone dangerous

Methylchloroisothiazolinone (MCI) can pose health risks, particularly as a skin irritant and sensitizer. It is commonly used as a preservative in cosmetic and personal care products, and some individuals may experience allergic reactions upon exposure. Due to its potential to cause dermatitis, regulatory agencies have recommended limits on its concentration in products. Overall, while it can be safe in regulated amounts, caution is advised for sensitive individuals.
