Hydroquinone Pharma Grade
Hydroquinone decreases the formation of melanin in the skin. Melanin is the pigment in skin that gives it a brown color.
Hydroquinone topical (for the skin) is used to lighten areas of darkened skin such as freckles, age spots, melasma(sun damage), or chloasma (darkened skin caused by hormonal changes).
Hydroquinone topical may also be used for purposes not listed in this medication guide.

Section 8 – EXPOSURE CONTROLS / PERSONAL PROTECTION
Appropriate Engineering Controls
Good general ventilation (typically 10 air changes per hour) should be used. Ventilation rates should be matched to conditions. If applicable, use process enclosures, local exhaust ventilation, or other engineering controls to maintain airborne levels below recommended exposure limits. If exposure limits have not been established, maintain airborne levels to an acceptable level.
Personal Protective Equipment
General information
Eye bath. Washing facilities. Safety shower.
Eye / Face Protection
Chemical goggles and face shield are recommended. Wear a full-face respirator, if needed.
Skin / Hand Protection
Wear chemical-resistant gloves, footwear, and protective clothing appropriate for the risk of exposure. Contact health and safety professional or manufacturer for specific information. Wash hands after contact.
Respiratory Protection
If engineering controls do not maintain airborne concentrations below recommended exposure limits (where applicable) or to an acceptable level (in countries where exposure limits have not been established), an approved respirator must be worn. In the United States of America, if respirators are used, a program should be instituted to assure compliance with OSHA Standard 63 FR 1152, January 8, 1998. Respirator type: Air- purifying respirator with an appropriate, government approved (where applicable), air-purifying filter, cartridge or canister. Contact health and safety professional or manufacturer for specific information.
Hygiene Measures
Observe good industrial hygiene practices.
