Recommended Restrictions: Not advised for direct intravenous use or unsupervised industrial formulation
Classification: Not classified as hazardous according to OSHA 29 CFR 1910.1200
Signal Word: None required under normal conditions
Hazard Statements: Prolonged skin exposure may cause irritation; accidental ingestion can cause mild gastrointestinal upset. Powder form may cause respiratory irritation.
Pictograms: Not required
Precautionary Statements: Avoid contact with eyes and prolonged skin contact; Handle with care to avoid dust inhalation
Other Hazards: Slippery when spilled on floor; Static discharge can ignite fine dust particles
Main Ingredient: Sodium polyacrylate — 85%
Copolymers: 2-Acrylamido-2-methylpropane sulfonic acid (AMPS), crosslinked — 10%
Preservative: Methylisothiazolinone — 0.1%
Water: 4.9% (residual moisture)
Other Impurities: Trace amounts of unreacted monomers and crosslinkers, non-hazardous, less than 0.1%
CAS Numbers: Sodium polyacrylate — 9003-04-7; AMPS — 15214-89-8; Methylisothiazolinone — 2682-20-4
Eye Contact: Rinse with fresh water for at least 15 minutes; lift eyelids. Call a doctor if redness or pain persists.
Skin Contact: Wash skin thoroughly with soap and water. Remove contaminated clothing.
Inhalation: Move affected person to fresh air and rest. Seek medical help if coughing or symptoms develop.
Ingestion: Rinse mouth, drink a small glass of water. Do not induce vomiting. Seek medical advice for large ingestion or if symptoms persist.
Suitable Extinguishing Media: Dry chemical, foam, carbon dioxide — water spray to cool containers
Unsuitable Media: Direct water stream for powdered product to avoid splashing contaminated material
Specific Hazards: Heated product emits small amounts of carbon monoxide, carbon dioxide, and traces of nitrogen oxides
Protective Equipment: Wear full protective gear and self-contained breathing apparatus
Additional Advice: Move containers from fire area if safe to do so. Prevent runoff into drains or waterways.
Personal Protections: Use gloves, goggles, and dust mask. Stay upwind for large spills.
Spill Procedure: Sweep or shovel bulk material into clean, dry containers. Avoid creating dust. Wash spill area with water to prevent slipping.
Environmental Precautions: Prevent further leakage if safe. Avoid entry into drains, surface water, and soil, especially large spills of powder.
Clean-Up Methods: Absorb residue on damp towels or absorbent material. Dispose of as non-hazardous waste unless contaminated with hazardous substances.
Safe Handling: Keep container closed when not in use. Minimize dust generation. Wear gloves for prolonged use.
Storage Conditions: Store at room temperature (59–77°F), away from moisture, strong oxidizers, high heat, and direct sunlight.
Incompatible Materials: Strong acids, strong bases, oxidizers; avoid contact with anhydrides and acyl chlorides
Other Precautions: Use only in well-ventilated areas. Ensure containers are clearly labeled and undamaged.
Exposure Limits: Sodium polyacrylate — ACGIH TLV not established; NIOSH REL not established. Use occupational dust limits (10 mg/m³ — total dust).
Engineering Controls: Local exhaust ventilation recommended for handling bulk powder
Personal Protective Equipment: Nitrile or latex gloves; splash-resistant goggles; N95 or equivalent mask for dusty operations
Hygiene Measures: Wash hands after handling and before eating. Remove contaminated clothing and launder before reuse.

Toxicity: Low acute toxicity to aquatic life; LC50 (fish, 96h) > 100 mg/L
Persistence and Degradability: Polymer structure resists breakdown; eventually biodegrades in soil over years
Bioaccumulation Potential: Does not bioaccumulate in aquatic or terrestrial organisms
Mobility in Soil: Tends to stay in upper soil layers due to swelling; not prone to leaching
Other Adverse Effects: May contribute to physical blockage in soil pores if released in bulk quantities
Waste Disposal: Incinerate or landfill according to local, state, and federal regulations
Container Disposal: Empty containers may contain trace residues; triple rinse before recycling or disposal
