Functions / Application
- Monobenzone Powder is a compound used as a topical drug for medical depigmentation.
- The topical application of monobenzone powder in animals decreases the excretion of melanin from melanocytes. The same action is thought to be responsible for the depigmenting effect of the drug in humans.
- Monobenzone Powder may cause destruction of melanocytes and permanent depigmentation.
- The histology of the skin after depigmentation with topical monobenzone powder is the same as that seen in vitiligo.
- The epidermis is normal except for the absence of identifiable melanocytes.

Frequently Asked Questions
Monobenzone (CAS 103-16-2), or hydroquinone monobenzyl ether, is an active pharmaceutical ingredient (API) that works by inhibiting tyrosinase and selectively destroying melanocytes, leading to permanent medical depigmentation.
Yes, Monobenzone causes irreversible depigmentation through the elimination of melanocytes in the treated skin area, producing histological skin conditions identical to extensive vitiligo.
Our Monobenzone powder is of pharmaceutical grade with an HPLC assay purity of ≥98% (typically testing at 99.05%), featuring low heavy metal residues and strict microbiological compliance.
Monobenzone is slightly soluble in water, but readily dissolves in organic solvents such as ethanol, ether, and acetone, making it straightforward to formulate into topical ointments and creams.
Standard packaging includes 1kg aluminum foil bags with double inner plastic bags packaged in outer cartons, as well as 10kg to 25kg bulk fiber drums with internal protective lining.
Small orders (1kg-25kg) ship via express couriers (DHL, FedEx, UPS, EMS) within 3-7 days door-to-door. Larger quantities can be dispatched via air freight (3-7 days) or sea freight (10-35 days).
