Hydroquinone is a pigment-lightening agent used in bleaching creams. Hydroquinone combines with oxygen very rapidly and becomes brown when exposed to air. Although it occurs naturally, the synthetic version is the one commonly used in cosmetics. Application to the skin may cause allergic reaction and increase skin sun sensitivity. Hydroquinone is potentially carcinogenic and is associated with causing ochronosis, a discoloration of the skin. The u.S. FDA has banned hydroquinone from oTC cosmetic formulations, but allows 4 percent in prescription products.

1,4-dihydroxybenzene, also known as hydroquinone, is an important chemical raw material. Its appearance is white acicular crystal. 1,4-dihydroxybenzene is widely used as an important raw material, intermediate and auxiliary agent for medicine, pesticides, dyes and rubber. It is mainly used as developer, anthraquinone dye, azo dye, rubber antioxidant and monomer polymerization inhibitor, food stabilizer and coating antioxidant, petroleum anticoagulant, synthetic ammonia catalyst, etc. It can also be used as analytical reagent, reducing agent and developer of copper and gold.
