Supplier: Manufacturer or distributor contact information should be available on the packaging or via invoice
Emergency Contact: Reference emergency telephone number provided by supplier or local emergency services
GHS Classification: Not classified as hazardous according to GHS standards
Health Hazards: Exposure may cause minor eye or skin irritation; ingestion of large quantities may affect gastrointestinal tract
Environmental Hazards: Low toxicity towards aquatic life, though excessive release may contribute to water body turbidity
Specific Hazards: Dust generated during processing can cause discomfort if inhaled
Labelling Elements: Not required for products not considered hazardous; precautionary advice regarding dust still recommended
Potential Risks: Higher concentrations of airborne dust may risk respiratory irritation and mild allergies
Chemical Name: Sodium Carboxymethyl Starch
CAS Number: 9063-38-1
Percentage: Typically 95-100% sodium carboxymethyl starch
Impurities/Additives: Trace sodium chloride, moisture less than 10%, possible trace unreacted starch material
Formulation: Powder or granular solid, white to slightly off-white
Inhalation: Move to fresh air; seek medical advice if persistent cough or discomfort continues; dust masks may help reduce risk
Skin Contact: Wash thoroughly with soap and water; remove soiled clothing if irritation occurs
Eye Contact: Rinse with clean water for several minutes; seek medical attention if redness or discomfort persists
Ingestion: Rinse mouth with water, drink water to dilute; seek medical help for large ingestion or symptoms
Note for First Responders: Symptomatic treatment only; observe for signs of allergic reaction especially in sensitive individuals
Suitable Extinguishing Media: Water spray, foam, dry chemical powder, carbon dioxide
Specific Hazards: May emit carbon monoxide, carbon dioxide or sodium oxides in a fire
Protective Equipment: Wear self-contained breathing apparatus and full protective gear
Explosion Risk: Dust in high concentrations can create combustible dust clouds; manage dust accumulation
Special Procedures: Cool affected containers with water spray to avoid rupture
Personal Precautions: Avoid breathing dust, use adequate ventilation, wear dust mask if necessary
Environmental Precautions: Prevent large quantities entering waterways, drains or soil
Spill Cleanup: Sweep up carefully without generating dust, collect in suitable containers, wash spill site with water
Disposal of Waste: Dispose according to local, national or international regulations for non-hazardous waste
Handling: Avoid generating or breathing dust, wash hands after use, ensure work area ventilation
Safe Storage Conditions: Store in cool, dry, well-ventilated area, keep containers tightly sealed, avoid moisture and humidity
Incompatible Materials: Strong oxidizers, strong acids
Hygiene Measures: No eating, drinking or smoking during handling, use proper personal protective equipment
Occupational Exposure Limits: No established limits for sodium carboxymethyl starch; general dust limits may apply (nuisance dust: 10 mg/m³ inhalable, 3 mg/m³ respirable)
Engineering Controls: Use local exhaust ventilation to minimize airborne dust
Personal Protective Equipment: Dust mask or respirator as needed, safety goggles to protect eyes, gloves for skin protection
