Potential health effects

ROUTES OF ENTRY..................: Eye and skin contact, inhalation of vapors or mists, accidental ingestion. HUMAN EFFECTS AND SYMPTOMS OF OVEREXPOSURE: ACUTE INHALATION..............: The hydroquinone, potassium carbonate, and sodium formaldehyde bisulfite in this product is expected to be irritating to the respiratory tract with symptoms of coughing, sore throat, and runny nose. Sulfites may cause an allergic reaction in some asthmatics and sulfite sensitive individuals. Possible symptoms include bronchoconstriction, sweating, flushing, hives, rapid heart rate, decreased blood pressure, and anaphylaxis. Inhalation of triethylene glycol vapors is unlikely due to its low vapor pressure. However, if misted or handled at elevated temperatures, high concentrations of triethylene glycol can produce drowsiness, headache, dizziness, and nausea. CHRONIC INHALATION............: Persons who have been previously sensitized to sulfites should take precautions to prevent the inhalation of potassium metasulfite and sodium formaldehyde bisulfite. ACUTE SKIN CONTACT............: Hydroquinone and sodium formaldehyde bisulfite can be irritating to the skin with symptoms of reddening, itching, and swelling. Potassium carbonate can be severely irritating with symptoms of reddening, itching, swelling, and possible burns. Hydroquinone may cause skin sensitization with symptoms of rash, itching, hives, and swelling. CHRONIC SKIN CONTACT..........: Sensitization with dermatitis or hives may occur. Repeated or prolonged contact to sulfites may cause an allergic skin reaction in sensitive individuals. ACUTE EYE CONTACT.............: Hydroquinone and sodium formaldehyde bisulfite can be irritating to the eyes with symptoms of tearing, stinging, reddening, and swelling. Potassium carbonate can be severely irritating with possible burns. CHRONIC EYE CONTACT...........: Repeated exposure to hydroquinone may cause intolerance of the eyes to light. In addition, repeated overexposure to hydroquinone may cause pigment deposition, which can extend into the cornea with continued exposure to high concentrations. This pigment deposition does not impair vision. ACUTE INGESTION...............: Ingestion of this product may cause gastrointestinal irritation. Hydroquinone may be harmful if swallowed with symptoms including nausea, vomiting, drowsiness, dizziness, disorientation, bluish skin color, and stomach pain. CHRONIC INGESTION.............: None known. OTHER EFFECTS OF EXPOSURE.....: See Section 11. CARCINOGENICITY NTP.........................: Not listed IARC........................: Not listed OSHA........................: Not Listed MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE......: Persons with preexisting eye or skin conditions or impaired pulmonary function may be more susceptible to the effects of this product.
