Chemical Name: Sodium Sulfate Decahydrate Common Name: Glauber's salt Synonyms: Disodium sulfate decahydrate Chemical Formula: Na2SO4·10H2O Physical State: Solid, crystalline Odor: Odorless Color: White Uses: Cleaning agents, textile manufacturing, laboratory purposes, and as a drying agent
Classification: Not classified as hazardous by GHS standards Main Hazards: Irritation to eyes and skin after prolonged or direct contact; dust inhalation may cause slight respiratory irritation Health Effects: Minimal for healthy adults, but sensitive individuals may notice irritation, especially to moist skin or eyes Environmental Hazard: Large spills can disrupt water balance for local organisms Pictograms: No required hazard symbols based on current evidence Signal Word: Not applicable
Ingredient: Sodium sulfate decahydrate Chemical Composition: Around 99% pure substance by mass Impurities: Trace amounts of sodium chloride, sodium carbonate, or other sodium compounds depending on source
Eye Contact: Rinse immediately with water, seek medical help if irritation sticks around Skin Contact: Wash off with soap and water, remove contaminated clothes Inhalation: Move to fresh air; wash face and hands, drink water if throat feels scratchy Ingestion: Rinse mouth, drink extra water, and get medical advice if a lot is swallowed
Flammability: Not flammable Suitable Extinguishing Media: Use water spray, dry chemical, foam, or carbon dioxide for surrounding fires Fire Hazards: Sodium sulfate decahydrate doesn’t fuel fire but can create slippery floors when wet Protective Equipment: Standard gear for chemical fires, including mask and gloves Decomposition Products: None under normal fire conditions, but strong heating releases water vapor
Personal Protection: Gloves for skin, eye protection if dust is in the air Spill Cleanup: Sweep up dry material, avoid creating dust clouds, collect into containers Environmental Precaution: Keep out of water systems in large amounts to prevent environmental imbalance Disposal Method: Any remaining solution or solid can be flushed with excess water, making sure local rules allow it Ventilation: Work in an open or well-ventilated area
Handling: Avoid direct skin and eye contact, prevent dust generation Storage: Keep in a dry, cool place away from moisture; closed containers work best Incompatibilities: Acids may trigger mild reactions; store away from strong oxidizing agents General Hygiene: Wash hands after working, avoid eating or drinking near work area
Occupational Exposure Limits: No strict limits for this compound in most jurisdictions Engineering Controls: Natural or forced ventilation Personal Protective Equipment: Gloves recommended for direct handling; eye shield for dusty environments Respiratory Protection: Mask or dust respirator if there’s lots of airborne material Hygiene Measures: Clean work clothing, regular hand washing
Appearance: Transparent to white crystals Odor: None Density: Around 1.46 g/cm3 Melting Point: Around 32.4°C, melts in its own waters of hydration Boiling Point: Not applicable as it releases water, not vaporizes as a solid Solubility: Readily dissolves in water pH (1% solution): Mildly alkaline Vapor Pressure: Negligible at room temperature Evaporation Rate: Not relevant
Chemical Stability: Stable at room temperature and normal storage Reactivity: May break down, giving off water if heated above 32°C Incompatible Materials: Strong acids may release some SO2 Polymerization: Doesn’t spontaneously polymerize Hazardous Decomposition: None under routine use
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion Symptoms: Dust can dry skin or irritate eyes; accidental high intake by mouth may lead to upset stomach Carcinogenicity: Research gives no suspicion of cancer risk for humans Long-term Exposure: No strong evidence for harm, but good hygiene matters for regular users Medical Attention: Seek help if exposure brings more than mild and temporary symptoms
Environmental Mobility: Dissolves quickly and spreads in water Bioaccumulation: Doesn’t build up in animal or plant tissue Aquatic Toxicity: High concentrations can disturb fresh water habitats Degradation: Sodium sulfate breaks apart naturally and joins background sodium and sulfate in the environment Persistence: Not persistent in soil or water Precautions: Avoid dumping excess material in lakes or streams
Recommended Disposal: Dilute with lots of water if flushed to sewer, make sure local laws allow this Solid Waste: If not allowed to put in water systems, send to landfill suited for chemical waste Incineration: Not required; material doesn’t burn Container Disposal: Clean and recycle or follow local drum disposal rules Minimization: Limit large-scale disposal into nature
UN Number: Not regulated for road, air, or sea transport Shipping Name: Sodium Sulfate Decahydrate Class: Not classified as hazardous for transport Packing Requirements: Seal against moisture to prevent clumps Spillage Advice: Use bags or bins robust enough to stand a fall
Labeling: Not subject to special hazard labeling under most regulations Restrictions: No major restrictions on handling or storage by workplace safety codes Reporting Requirements: Not listed as a toxic or controlled substance in most countries Worker Protection: Standard personal protection rules suffice Special Regulations: None commonly in force for this material
