Classification: Non-hazardous under normal conditions of use for food-grade applications
Label Elements: No specific hazard pictograms required for food emulsifier-grade ammonium phosphatides
Signal Word: Not applicable
Hazard Statements: Product may cause mild eye irritation, especially in bulk or powder form
Precautionary Statements: Avoid unnecessary contact with eyes and prolonged skin exposure, wash hands after handling
Other Hazards: Dust generation possible if product is handled in powder form; inhaling dust can cause mild respiratory irritation
Chemical Composition: Complex mixture of ammonium salts of phosphatidic acids and related phospholipids
Percentage: Typically 100% ammonium phosphatides for food applications, trace impurities related to natural origin of phospholipids
Other Ingredients: None significant to user safety for food-grade quality
Impurities: Trace amounts of natural oils or fatty acids depending on source material
Inhalation: Move affected person to fresh air, monitor for coughing or throat irritation, seek medical attention if symptoms persist
Eye Contact: Rinse cautiously with water for 15 minutes, remove contact lenses if present, avoid rubbing eyes, consult medical advice for persistent irritation
Skin Contact: Wash thoroughly with soap and water, remove contaminated clothing, seek medical attention for persistent redness or irritation
Ingestion: Rinse mouth with water, drink water in small sips, observe for gastrointestinal symptoms, consult a physician if large quantities are ingested or if symptoms develop
Suitable Extinguishing Media: Water spray, foam, dry chemical, or carbon dioxide can be used
Unsuitable Extinguishing Methods: Avoid strong water jets that may spread the material
Specific Hazards: Combustion of bulk material may release ammonia, phosphorus oxides, low levels of organic vapors
Protective Equipment for Firefighters: Wear self-contained breathing apparatus and full protective gear
Special Precautions: Remove containers from fire area if safe to do so, prevent runoff from entering water sources
Personal Precautions: Avoid dust generation, wear gloves and safety goggles, ventilate area
Environmental Precautions: Prevent product from entering drains, waterways, and soil; report large spills to local authorities
Cleanup Methods: Shovel or sweep up material for disposal, use damp cloths for smaller quantities, clean contaminated area with detergent and water
Handling: Use with adequate ventilation, minimize dust generation in bulk handling, avoid contact with eyes and prolonged skin exposure
Storage Conditions: Store in dry, cool, well-ventilated area away from strong oxidizing agents and incompatible chemicals
Packaging Materials: Use original container, keep tightly closed to protect from moisture and contamination
Specific Uses: Use according to food manufacturing safety procedures for emulsifiers
Occupational Exposure Limits: No established limits for ammonium phosphatides
Engineering Controls: Implement local exhaust ventilation where dust might be present or where high volumes are handled
Personal Protective Equipment: Wear protective gloves, safety glasses or goggles, dust masks under conditions of potential airborne material exposure
Hygiene Measures: Wash hands after handling, do not eat or drink when handling bulk material, change contaminated clothing and wash before reuse
Appearance: Pale yellow to brownish oil or viscous liquid; sometimes available as a paste or powder

Serious Eye Damage/Irritation: Mild, transient irritation possible; cones with food industry reports
Respiratory Sensitization: No noted data for respiratory sensitization in humans
Chronic Toxicity: No chronic toxicity reported at levels commonly found in processed foods; long-term consumption evaluated by food safety agencies
Carcinogenicity: No evidence of carcinogenic effects for food-grade product
Other Effects: Individuals with rare phospholipid sensitivities may experience mild gastrointestinal discomfort
Toxicity (Aquatic): Low toxicity to aquatic life based on available studies; degradable in natural environments
Persistence and Degradability: Biodegradable under normal environmental conditions
Bioaccumulation Potential: Not expected to bioaccumulate in aquatic organisms
Mobility in Soil: Moves slowly through soil in presence of water; unlikely to contaminate groundwater
Other Adverse Effects: Minimal risk to wildlife at quantities used in food manufacturing
Waste Treatment Methods: Dispose in approved landfill or through industrial incineration following local and national regulations
Packaging Disposal: Rinse thoroughly if re-used or recycled, discard in accordance with food safety and environmental laws
Additional Guidance: Prevent product from entering waterways or municipal drains in significant quantities
