Purity: 98–100% by weight
Impurities: Water traces, seaweed residues, possibly trace metals from natural sources
Inhalation: Move person to fresh air, offer water to rinse mouth, seek medical attention if symptoms persist
Skin Contact: Wash with plenty of water and mild soap, remove contaminated clothing, seek advice if irritation develops
Eye Contact: Rinse eyes with water for at least 15 minutes, lift eyelids occasionally, remove contacts if present, seek medical help if discomfort remains
Ingestion: Rinse mouth with water, do not induce vomiting, seek advice if large amount consumed or symptoms show
Note to Physician: Treat based on symptoms, consider symptomatic and supportive care depending on exposure route and quantity
Suitable Extinguishing Media: Use dry chemical powder, CO2, water spray, or foam
Specific Hazards: Combustible at high temperatures, may release carbon oxides or other non-toxic vapors on burning
Protective Equipment for Firefighters: Use full protective gear and self-contained breathing apparatus, avoid breathing smoke or combustion products
Special Fire-fighting Procedures: Move containers away from fire if safe, cool containers with water spray, prevent water runoff from entering drains or waterways
Spill Cleanup: Sweep up spilled solid carefully to prevent dust clouds, use vacuum with HEPA filter for fine powder, place residue in properly labeled waste container
Personal Precautions: Wear dust mask, goggles, gloves to minimize direct contact and inhalation
Environmental Precautions: Avoid releasing large quantities into water, soil, or drains, minimize impact by using absorbent materials if necessary
Safe Handling: Minimize dust creation, handle inside ventilation hoods or extraction local to source, wash hands thoroughly after use
Storage Conditions: Store in tightly closed containers, keep in cool, dry, well-ventilated area, protect from direct sunlight or moisture
Compatibility: Keep away from strong oxidizers and acids, avoid contact with incompatible substances
Engineering Controls: Provide adequate general and local exhaust ventilation in processing and packing areas
Respiratory Protection: Use dust respirators (N95 or equivalent) in high-dust environments, especially at industrial scale
Hand Protection: Wear chemical-resistant gloves, disposable nitrile or latex gloves recommended for frequent contact
Eye Protection: Use safety goggles or full-face shield in processing plants or if dust is generated
Skin Protection: Use protective clothing, aprons, and closed footwear to avoid skin contact
Occupational Exposure Limit: No established limit for alginic acid; keep exposure as low as possible, reference to inert nuisance dust threshold (< 10 mg/m3)
Appearance: Off-white to light brown powder or granules
Odor: Slight, specific, seaweed-like odor

Acute Toxicity: Low toxicity, oral LD50 for rats > 5,000 mg/kg; not toxic by dermal or inhalation exposure
Skin Irritation: May cause mild, transient irritation for sensitive skin
Eye Irritation: Dust can cause mild, reversible irritation and itching
Chronic Exposure: No data showing long-term adverse health effects in occupational or consumer use under normal conditions
Sensitization: Not reported to cause allergic reactions or respiratory sensitization in routine handling
Carcinogenicity/Mutagenicity: Not classified as carcinogenic, mutagenic, or toxic for reproduction by major regulatory agencies
Other Effects: No reproductive, developmental, or systemic toxicity under recommended use levels
Toxicity to Aquatic Life: Not toxic to aquatic organisms in typical concentrations, acts as biodegradable organic matter
Persistence & Degradability: Breaks down naturally through microbial action in soil and water environments
Bioaccumulation Potential: Unlikely to bioaccumulate, degraded to simple sugars by environmental microbes
Mobility in Soil: Low mobility, binds to minerals and organic matter in soil
Other Information: No long-term adverse effects on environmental balance reported in published environmental impact studies
Waste Collection: Collect in closed, labeled containers for proper disposal
Disposal Methods: Consult local regulations, may dispose as non-hazardous solid waste, suitable for composting or landfill depending on regional waste codes
