Impurities / Additives: May contain up to 5% minor constituents including sodium salts of other fatty acids and residual water, not considered hazardous.
Inhalation: Remove to fresh air. If breathing is difficult, seek medical attention. Rinse mouth and nose with water.
Skin Contact: Wash exposed skin with plenty of water and mild soap. Remove contaminated clothing.
Eye Contact: Rinse eyes gently with clean water for 15 minutes. Remove contact lenses if present and easy to do. Medical attention if irritation persists.
Ingestion: Rinse mouth thoroughly with water. Do not induce vomiting. Obtain medical advice if symptoms develop.
Notes for Physician: Treat symptomatically, no specific antidote available.
Suitable Extinguishing Media: Use water spray, dry chemical, foam, or carbon dioxide.
Unsuitable Extinguishing Media: Avoid straight water stream as it may spread product.
Specific Hazards: Decomposition may produce irritating fumes or toxic smoke such as carbon monoxide, carbon dioxide, and sodium oxides.
Protective Equipment: Firefighters should wear self-contained breathing apparatus with full protective clothing.
Fire/Explosion Risks: Dust can form explosive mixtures in air; avoid high concentrations of airborne dust; avoid ignition sources.
Personal Protection: Wear suitable protective clothing, gloves, and goggles to minimize contact.
Environmental Precautions: Prevent entry into waterways, drains, or soil. Avoid release to the environment.
Methods for Clean-Up: Sweep up and collect spilled material for reuse or disposal. Avoid generating dust. Wash spill area with water after removal of solid material. Dispose in accordance with local regulations.
Handling: Minimize dust generation and accumulation. Use with adequate ventilation. Avoid contact with eyes and skin. Do not eat, drink, or smoke in work area. Wash thoroughly after handling.
Storage Conditions: Store in tightly closed containers in a cool, dry, well-ventilated area. Protect from moisture, excessive heat, and direct sunlight. Keep away from strong oxidizing agents. Separate from incompatible materials.
Exposure Limits: No established occupational exposure limits for sodium stearoyl lactylate. General particulate not otherwise regulated (PNOR): total dust 15 mg/m³, respirable fraction 5 mg/m³ (OSHA PEL).
Engineering Controls: Provide local exhaust or general ventilation to limit inhalation of dust.
Personal Protective Equipment: Wear safety glasses with side shields, disposable or chemical-resistant gloves, and dust mask where dust is generated. Use appropriate protective clothing to prevent skin contact.
Hygiene Measures: Keep work clothes separate. Wash hands after handling and before eating.

Carcinogenicity: Not listed by NTP, IARC, or OSHA as a carcinogen
Reproductive Toxicity: No evidence of adverse reproductive or developmental effects
Repeated Dose Toxicity: No known significant effects or critical hazards from repeated doses under normal use.
Ecotoxicity: Not expected to be harmful to aquatic life at low concentrations. Data for similar substances suggest a low hazard for environmental organisms.
Persistence and Degradability: Readily biodegradable under typical environmental conditions.
Bioaccumulative Potential: Low potential for bioaccumulation. Fatty acid structure metabolizes naturally.
Mobility in Soil: Expected to have low mobility due to surfactant properties and partial solubility.
Other Adverse Effects: No evidence of significant ecological impact with normal usage and disposal practices.
Disposal Methods: Follow local, regional, and national regulations. Can be landfilled or incinerated in accordance with environmental regulations. Reuse or recycle if practical. Dilute residues with water before discharge to wastewater treatment systems if allowed.
