About 5-Amino-4-chloro-2-methylphenol hydrochloride

5-amino-4-chloro-2-methylphenol Hydrochloride is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

Detailed Analysis

5-Amino-4-chloro-2-methylphenol hydrochloride is a salt of a chlorinated aminophenol derivative used as an intermediate in permanent hair dye formulations. The compound contains both an amino group (providing dye precursor functionality) and a chlorine substituent. While not explicitly listed in EU Annex II as a prohibited substance, its structural similarity to other restricted aromatic amines raises regulatory scrutiny. The hydrochloride salt form can dissociate, releasing chloride ions that may affect skin barrier integrity in compromised skin. EU cosmetics regulation requires hair dye substances to undergo safety assessment, and this compound requires professional handling with appropriate protective measures during manufacturing.
