However, the CAS # 10043 -01 -3 is for the anhydrous form. Hydrated aluminum sulfate, Al2(SO4)3* 18H2O, is efflorescent and therefore may have approximately 14 molecules of water. The hydrate form may be indicated as "xH2O" and assigned CAS # 17927 -65 -0. Component Related Regulatory Information This product may be regulated, have exposure limits or other information identified as the following: Aluminum, soluble salts, Aluminum (7429- 90 -5). Component Information /Information on Non - Hazardous Components This product is considered hazardous under 29 CFR 1910.1200 (Hazard Communication). II * * * Section 3 - Hazards Identification * * * II Emergency Overview Aluminum Sulfate is an odorless, lustrous white to grayish -white crystalline, granular or powdered solid. This material can cause severe irritation and inflammation, or burns to the eyes and skin. Contact with high concentration or prolonged contact may cause permanent damage. Inhalation of high airborne concentrations may cause constriction of the airways. Dusts can form corrosive sulfuric acid when in contact with moisture in air or tissues. Concentrated solutions are corrosive to the eyes, skin and gastrointestinal tract. When heated to decomposition, Aluminum Sulfate may emit toxic and corrosive fumes of sulfur dioxide and/or sulfur trioxide. Hazard Statements WARNING! Causes eye, skin, respiratory tract, and gastrointestinal tract irritation or burns. Harmful if swallowed or inhaled. Do not get in eyes, on skin or on clothing. Do not breathe dusts. Wash thoroughly after handling. Keep container closed. Use only with adequate ventilation. Potential Health Effects: Eyes Aluminum Sulfate can cause severe irritation and inflammation of the eyes. Concentrated solutions may cause permanent damage or blindness. Potential Health Effects: Skin Aluminum Sulfate dusts can irritate the skin. Concentrated solutions are corrosive and may cause burns and permanent scarring. Prolonged exposure can cause numbing of the fingers. Prolonged contact can result in dermatitis (dry, red, itchy skin). Potential Health Effects: Ingestion May cause burns to the mouth, throat and stomach. Symptoms may include vomiting, nausea, bleeding stomach, and abdominal pain. Ingestion of small amounts of aluminum sulfate may cause a sensation of dryness in the mucous membranes of the mouth and throat. Adverse effects on muscle and kidneys, and gum necrosis have been reported after ingestion of large amounts of aluminum compounds. Repeated ingestion over prolonged period can result in phosphate deficiency, which can cause softening and bending of bones. The approximate fatal dose in humans by ingestion is 30 grams.
