Sodium Polyacrylate CAS 9003-04-7

1. Sodium polyacrylate is a "superabsorbent polymer" capable of absorbing and retaining hundreds of times its weight in water, making it the key component in baby diapers, sanitary napkins, and adult incontinence products .
2. The compound is used to solidify aqueous liquid waste, such as concrete slurries, medical waste, and sludge from industrial ponds, by rapidly absorbing fluids and forming a gel .
3. Sodium polyacrylate CAS 9003-04-7 serves as a thickening agent in various products, a fire-retardant gel, and is also used to create artificial snow for holiday decorations and movie productions .

1. Store Sodium polyacrylate in a tightly sealed container in a cool, dry place, as it is moisture sensitive and swells upon contact with water .
2. Keep Sodium polyacrylate CAS 9003-04-7 strictly away from strong oxidizing agents to prevent violent reactions and fire hazards .
3. Handle Sodium polyacrylate using appropriate personal protective equipment including safety goggles and protective gloves to avoid mechanical irritation to eyes and skin from the dust, and use ventilation or a dust mask to prevent inhalation .

1. Isolate the spill area, wear personal protective equipment including a particulate filter respirator, and sweep up solid Sodium polyacrylate into covered containers; if appropriate, moisten the material first to prevent dusting .
2. Prevent spilled Sodium polyacrylate CAS 9003-04-7 from entering drains or waterways, and wash away any remaining residue with plenty of water after collection .
3. Personnel cleaning Sodium polyacrylate spills must dispose of waste in accordance with local, state, and federal regulations, as large quantities released into the environment may pose a hazard .

1. Sodium polyacrylate is generally considered non-hazardous by GHS classifications , though some sources assign a "Warning" signal word (GHS07, GHS09) with hazard statements H315 (skin irritation), H319 (serious eye irritation), and H335 (respiratory irritation) .
2. Sodium polyacrylate CAS 9003-04-7 is combustible and finely dispersed particles can form explosive mixtures in air; it reacts violently with strong oxidants, and thermal decomposition produces toxic fumes including carbon oxides (CO, CO₂) .
3. Sodium polyacrylate has an oral LD50 of 40,000 mg/kg in rats, indicating very low acute toxicity, but repeated or prolonged inhalation of dust may cause damage to the lungs ; it is very toxic to aquatic life with long-lasting effects (H400, H410, H411) according to some sources .
