103-16-2 Usage


ChEBI: The monobenzyl ether of hydroquinone. It is used as a topical drug for medical depigmentation.


Hydroquinone monobenzyl ether is an antidegradant added to rubber products; inhibitor in acrylic resins.


Monobenzone, also called 4-(Benzyloxy)phenol and monobenzyl ether of hydroquinone (MBEH) is an organic chemical in the phenol family with chemical formula C6H5CH2OC6H4OH. It is used as a topical drug for medical depigmentation. Monobenzone occurs as a white, almost tasteless crystalline powder, soluble in alcohol and practically insoluble in water. The topical application of monobenzone in animals, increases the excretion of melanin from the melanocytes. The same action is thought to be responsible for the depigmenting effect of the drug in humans.

Treatment for vitiligo

Monobenzone may cause destruction of melanocytes and permanent depigmentation.Hyperpigmented skin appears to fade more rapidly than does normal skin, and exposure to sunlight reduces the depigmenting effect of the drug. The histology of the skin after depigmentation with topical monobenzone is the same as that seen in vitiligo; the epidermis is normal except for the absence of identifiable melanocytes.This function enables it treat the uneven appearance of the skin due to a loss of skin color (vitiligo). It works by permanently removing color from normal skin located around skin with vitiligo. This will help to make the appearance of the skin more even.? What calls for special attention is that: Do not use this drug to treat other skin discoloration problems ("sun spots," "age spots," freckles, skin discoloration caused by hormone medicine, perfumes, pregnancy, or skin trauma). Monobenzone is not a mild cosmetic bleach. Because it causes a permanent discoloration of the skin, it may not be the right treatment for these other skin conditions. Besides, Monobenzone is also being considered for the treatment of Melanoma.


Toxic substance


Monobenzone (Benoquin) potently inhibits melanin production and destroys melanocytes. Like hydroquinone, monobenzone was originally introduced for the topical treatment of disorders of excess melanin pigmentation, including melasma. It is now used only to permanently depigment the remaining normally pigmented skin in patients with extensive vitiligo. Irritant and allergic contact dermatitis are common side effects.
