CAS Number: 9005-46-3
Recommended Uses: Food additive, emulsifier, stabilizer, ingredient in nutritional supplements, protein enrichment
Supplier Information: Contact details provided by manufacturer; essential for emergency situations or technical support
Emergency Telephone: Listed on MSDS provided by supplier or manufacturer
Restrictions on Use: Industrial applications and food production; avoid use in individuals with milk protein allergies
Classification: Not classified as hazardous under OSHA Hazard Communication Standard (29 CFR 1910.1200)
Main Hazards: Possible respiratory irritation from dust, risk of allergy reactions in individuals sensitive to milk proteins, mild eye and skin irritant
GHS Label: Not a hazardous substance, no pictogram required
Signal Word: None applicable
Hazard Statements: Dust inhalation may cause irritation; ingestion may provoke reaction in those allergic to dairy
Precautionary Statements: Avoid generating dust, wear protective gear to minimize inhalation and skin exposure, keep away from ignition sources in powdered form
Component: Sodium Caseinate
Concentration: >95% by weight
Impurities: Trace amounts of lactose, mineral salts, and moisture
Allergens: Contains milk protein (potential allergen)
Additional Components: Food-grade anti-caking agents possible in finished products; check specific supplier composition for minor ingredients
Inhalation: Move affected person to fresh air; encourage slow, deep breaths; seek medical attention if cough or shortness of breath develops
Eye Contact: Flush eyes with plenty of water for at least 15 minutes; lift eyelids to remove particles; contact a physician if irritation persists
Skin Contact: Wash exposed skin with mild soap and water; remove contaminated clothing; seek help if rash or irritation occurs
Ingestion: Rinse mouth thoroughly with water; drink plenty of water; if symptoms of allergic reaction appear (such as swelling, hives, or difficulty breathing), get emergency medical care
Advice for Physician: Treat based on symptoms; monitor for allergic reactions; provide supportive care as needed
Extinguishing Media: Use water spray, foam, dry chemical powder, or carbon dioxide
Specific Hazards: Fine powder can form explosive dust-air mixtures; product can burn at high temperatures, releasing carbon monoxide and nitrogen oxides
Special Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear
Hazardous Combustion Products: Carbon dioxide, carbon monoxide, nitrogen oxides
Advice for Firefighters: Use water spray to cool containers, avoid inhaling smoke and combustion gases, evacuate non-essential personnel from danger area
Personal Precautions: Minimize dust generation, avoid breathing dust, use protective gloves, safety goggles, and dust mask
Environmental Precautions: Prevent large spills from entering waterways, sewers, or drains; sodium caseinate can cause oxygen depletion if released in large amounts
Containment Methods: Sweep or vacuum up without generating dust; place material in appropriate waste container
Cleanup Procedures: Wash spill site with water after material pick-up; ventilate the area to clear remaining dust
Handling: Use in well-ventilated areas to minimize dust; avoid inhaling powder; keep away from open flames or hot surfaces
Hygiene Practices: Wash hands thoroughly after handling; remove contaminated clothing and clean before reuse; do not eat, drink, or smoke while handling
Storage Conditions: Store in a cool, dry, well-ventilated location away from moisture and incompatible materials; keep container tightly closed
Incompatibilities: Strong oxidizing agents; moisture exposure leads to caking and reduced product quality
Packaging Materials: Use food-grade, moisture-proof containers to preserve quality and safety
Engineering Controls: Provide local exhaust or general ventilation; avoid dust buildup
Personal Protection: Wear safety glasses or goggles, laboratory coat, and gloves; in bulk handling, use dust mask or respirator (NIOSH-approved if exposure limits are likely to be exceeded)
Occupational Exposure Limits: No established limit for sodium caseinate; treat as a nuisance dust, observe total particulate limits (e.g., ACGIH TLV for particulates not otherwise classified: 10 mg/m³ for total dust)
Environmental Exposure: Use dust collection systems to reduce plant emissions; monitor for release in processing areas
Appearance: White or off-white powder or granules
Odor: Mild, characteristic dairy scent
Melting Point: Decomposes before melting
Solubility: Dispersible in water forming colloidal solution; insoluble in alcohol
Bulk Density: 0.3–0.5 g/cm³
pH Value (1% solution): 6.0–7.5
Boiling Point: Not applicable for a protein
Flash Point: Not determined (usually non-flammable under normal conditions, but powder can present dust explosion risk)
Explosive Properties: Dust can form explosive mixture with air
Viscosity: Not applicable—behaves as a suspension in water
Auto-ignition Temperature: Not established
Chemical Stability: Stable in dry, cool conditions
Reactivity: Non-reactive under normal processing and storage
Incompatible Materials: Strong oxidizers, acids; moisture harms powder stability, causing caking
Hazardous Decomposition Products: At high temperatures, produces fumes including carbon monoxide, nitrogen oxides
Polymerization: Will not occur
Storage Life: Usually 12–24 months in unopened, dry containers
Acute Toxicity: Considered non-toxic; oral LD50 not established but expected to be high
Chronic Toxicity: No data on chronic toxicity, generally recognized as safe (GRAS) for food use
Routes of Exposure: Inhalation, ingestion, skin or eye contact
Symptoms of Exposure: Dust causes mild respiratory irritation, possible eye redness, minor skin irritation; allergic reactions possible in sensitized individuals
Carcinogenicity: Not listed as carcinogen by IARC, NTP, or OSHA
Reproductive Effects: No data indicating reproductive hazards
Ecotoxicity: Low risk, biodegradable protein; high concentrations may cause oxygen depletion in aquatic settings
Biodegradability: Readily biodegradable under environmental conditions
Bioaccumulation: No potential for bioaccumulation expected
Mobility in Soil: Minimal; will degrade naturally in soil and water
Other Adverse Effects: Product used in food industry without recognized significant environmental hazards; release into water bodies at large scale could harm aquatic life by promoting bacterial growth
Waste Treatment Methods: Dispose as non-hazardous organic waste in accordance with local regulations
Incineration: Suitable for high-volume disposal where permissible; does not produce hazardous residues
Landfill: Acceptable if allowed by local laws; minimize amount to limit attraction of vermin
Recycling: Not generally recycled; material may be composted on a limited basis
Precautions: Avoid uncontrolled release to environment; do not flush large amounts into drains or waterways
UN Number: Not regulated for transport
Proper Shipping Name: Not classified as a dangerous good
Transport Hazard Class: None
Packing Group: None
Environmental Hazards: Not a marine pollutant; prevent release of large amounts
Special Precautions: Transport in clean, dry, sealed containers; protect from moisture in transit
Label Requirements: None mandated by law
US Regulations: GRAS status by FDA as a food additive; not listed on SARA Title III hazardous substances; not subject to TSCA reporting
EU Regulations: Approved food additive (E469); not classified as dangerous under CLP Regulation
Canadian Regulations: Included in Domestic Substances List (DSL); no special controls
International: Covered under Codex Alimentarius for food applications; no shipping restrictions worldwide
Labeling Requirements: Allergen declaration mandatory for food products due to milk protein content
