Precautionary Advice: Avoid dust inhalation, touching eyes, or ingesting large quantities; use gloves and eye protection for bulk processing
Chemical Name: Ascorbyl Palmitate
CAS Number: 137-66-6
Purity: Not less than 98% as listed by manufacturers
Other Ingredients: None expected in pure substance; traces of ascorbic acid or palmitic acid residue possible in technical grades
Inhalation: Move individual to fresh air and allow to rest; seek medical attention if symptoms such as coughing or shortness of breath persist
Skin Contact: Wash affected area with soap and water; discontinue use if irritation or redness develops
Eye Contact: Rinse with running water for several minutes, holding eyelids open; remove contact lenses; seek medical advice if irritation does not subside
Ingestion: Rinse mouth with water, drink small quantities of water to dilute; do not induce vomiting unless instructed by medical personnel; consult a physician in case of large exposure
Extinguishing Media: Carbon dioxide, dry chemical powder, foam, or water spray suitable for small fires; avoid full water jets to prevent spread of fine particles
Hazards from Combustion: Combustion may produce carbon monoxide, carbon dioxide, and other irritating gases
Specific Fire Fighting Procedures: Wear suitable protective equipment; self-contained breathing apparatus for firefighters recommended due to toxic fumes
Fire and Explosion Risk: Dust can form explosive mixture in air in bulk storage or during processing; take proper precautions to avoid static discharge and excessive dust accumulation
Protective Measures: Keep containers cool with water spray, isolate area, and stay upwind of fire
Personal Precautions: Use dust mask, safety goggles, and gloves; ventilate area to disperse dust
Environmental Precautions: Prevent entry of large amounts into drains, surface water, or soil
Containment Methods: Sweep, vacuum, or scoop spilled material carefully; avoid generating dust clouds
Cleanup Techniques: Collect in suitable, labeled containers for disposal according to local regulations; wash down area with plenty of water to remove residue
Handling Practices: Minimize creation of airborne dust; operate with adequate ventilation; avoid breathing dust and contact with eyes and skin
Safe Storage: Store in tightly closed containers away from direct sunlight, moisture, heat, and oxidizing agents
Storage Temperature: Maintain below 25°C (77°F) or as recommended on product specification; keep dry
Precautionary Measures: Ground all equipment to prevent static discharge when transferring powder; restrict entry to storage areas to trained personnel
Occupational Exposure Limits: No established limits for ascorbyl palmitate; general dust limits (e.g., OSHA PEL for nuisance dust: 15 mg/m³ total dust) apply
Engineering Controls: Local exhaust ventilation or process enclosure to minimize dust levels
PPE Recommendations: Nitrile gloves, safety goggles, dust mask or NIOSH-approved respirator for high-dust environments; lab coats for handling bulk powder
Hygiene Measures: Wash hands after handling; avoid eating, drinking, or smoking in work area
