DIMETHYLHYDROQUINONE.

Avoid CAS 150-78-7 / PERFUMING

Dimethylhydroquinone (DMHQ) is a chemical compound primarily employed as an antioxidant in industrial applications and as a fragrance ingredient. While it demonstrates properties that mitigate oxidative degradation, its specific benefits and mechanisms for skin health are not substantiated by dedicated cosmetic research.

Summary

Antioxidant Fragrance ingredient

Science

Mechanism of Action

Dimethylhydroquinone functions as an antioxidant, capable of neutralizing free radicals and preventing oxidative processes. However, peer-reviewed literature specifically detailing its mechanisms of action on the skin, such as enzyme inhibition or cellular signaling relevant to dermatological benefits, is currently unavailable.

Safety Profile

CIR Status
Not reviewed
Sensitization risk High

The Cosmetic Ingredient Review (CIR) Expert Panel has not evaluated Dimethylhydroquinone. While the parent compound Hydroquinone has specific restrictions, DMHQ's various isomers present distinct and concerning hazard classifications. Risks for specific isomers include toxicity if swallowed, severe skin burns, serious eye damage, allergic skin reactions, respiratory irritation, and potential reproductive harm. A general safety data sheet for Dimethylhydroquinone also indicates potential for mild skin irritation.
