Hazard Identification

GHS Classification: Not classified as hazardous according to OSHA Hazard Communication Standard
Label Elements: Not required; typically, no pictogram or signal word
Potential Health Effects: May cause mild irritation to eyes and skin, inhalation of dust might irritate respiratory tract, ingestion in large amounts could upset the stomach
Physical Hazards: Fine powder may create dust clouds that carry a risk of combustion in certain conditions

Composition / Information on Ingredients

Component: Lysine (L-Lysine Monohydrochloride or equivalent form depending on product)
Purity: Typically ranges from 97% to 99%
Other Ingredients: May contain negligible amounts of water or stabilizers depending on preparation
Impurities: Trace mineral or manufacturing by-products, usually controlled and very low

First Aid Measures

Eye Contact: Flush eyes with plenty of water for several minutes; remove contact lenses if present and easy to do
Skin Contact: Wash exposed skin with soap and water; seek medical attention if rash or irritation develops
Inhalation: Move person to fresh air; seek medical attention if breathing becomes difficult
Ingestion: Rinse mouth thoroughly; drink water to dilute; seek medical help if large amount swallowed or if symptoms appear

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, or foam
Unsuitable Media: Do not use direct water jet on powder to avoid spreading
Fire Hazards: Fine dust may form explosive mixture with air under certain conditions
Protective Equipment: Firefighters should use self-contained breathing apparatus and full protective clothing
Hazardous Combustion Products: Carbon monoxide, carbon dioxide, nitrogen oxides may form on combustion

Accidental Release Measures

Personal Precautions: Wear protective gloves, safety goggles, and dust mask
Environmental Precautions: Prevent runoff to waterways; contain spill if safe to do so
Methods for Cleanup: Sweep or vacuum spilled material; avoid raising dust; place in appropriate labeled waste container for disposal

Handling and Storage

Handling: Avoid creating dust; use with adequate ventilation; wash hands after handling
Storage Conditions: Store in original packaging in cool, dry, well-ventilated area; keep container tightly closed
Incompatible Materials: Strong oxidizers, acids, bases
Special Handling Procedures: Use clean, dry utensils to avoid contamination; minimize prolonged or repeated exposure

Exposure Controls and Personal Protection

Occupational Exposure Limits: No specific regulatory limit, control dust below nuisance dust levels (<10 mg/m3 for total dust)
Engineering Controls: Use local exhaust ventilation where dust generation occurs
Personal Protective Equipment (PPE): Safety glasses, laboratory coat, dust respirator or mask (in dusty conditions), gloves (particularly for those with sensitive skin)
Hygiene Measures: Wash hands thoroughly after handling, do not eat, drink, or smoke during use

Physical and Chemical Properties

Appearance: White or nearly white powder or crystals
Odor: Slight odor, similar to amino compounds
Odor Threshold: Not determined
pH: Approximately 5-6 (1% solution)
Melting Point: 215-225°C (decomposes)
Boiling Point: Not applicable
Flash Point: Not applicable
Evaporation Rate: Not applicable
Flammability: May form combustible dust-air mixtures
Explosive Properties: Dust can form explosive mixtures in air
Vapor Pressure: Not volatile
Molecular Weight: 146.19 g/mol for L-Lysine base
Solubility: Soluble in water; very slightly soluble in ethanol
Partition coefficient (log Kow): –4.2 (estimated)

Stability and Reactivity

Chemical Stability: Stable under normal conditions of storage and handling
Reactivity: Not reactive under normal use conditions
Conditions to Avoid: Excess heat, moisture, and ignition sources; avoid creating and dispersing dust
Incompatible Materials: Strong oxidizers, acids, some bases
Hazardous Decomposition Products: Thermal decomposition can release toxic gases such as carbon oxides and nitrogen oxides

Toxicological Information

Acute Toxicity: Oral LD50 (Rat): >5,000 mg/kg; considered non-toxic in typical exposures
Skin Corrosion/Irritation: Not expected to be corrosive; may cause mild irritation
Serious Eye Damage/Irritation: May cause eye irritation when exposed to dust
Respiratory or Skin Sensitization: Not known to cause sensitization
Chronic Effects: No evidence of long-term health effects from routine exposure
Carcinogenicity: Not listed as a carcinogen by IARC, NTP, or OSHA
Reproductive Toxicity: Not expected at anticipated exposure levels
Other Information: Ingestion of large quantities may cause gastrointestinal upset

Ecological Information

Ecotoxicity: Expected to have low toxicity to aquatic life based on structure and rapid biodegradability
Persistence and Degradability: Readily biodegradable in soil and water
Bioaccumulative Potential: Low, does not bioaccumulate in organisms
Mobility in Soil: High solubility in water increases mobility, but rapid degradation limits environmental risk
Other Adverse Effects: Not anticipated under normal usage patterns; spills may cause short-term nutrient enrichment in water bodies

Disposal Considerations

Waste Disposal: Collect and place in suitable containers for disposal; dispose in accordance with local, regional, and national regulations
Packaging Disposal: Clean containers can be recycled or disposed of as non-hazardous waste; contaminated packaging may require special handling
Special Precautions: Avoid releasing large quantities to environment

Transport Information

UN Number: Not classified as dangerous goods
UN Proper Shipping Name: Not regulated
Transport Hazard Class: Not applicable
Packing Group: Not applicable
Special Precautions: Prevent spillage and dust formation during transport; ensure containers are secure and labeled

Regulatory Information

OSHA: Not classified as hazardous under OSHA Hazard Communication Standard
TSCA: Listed on U.S. Toxic Substances Control Act inventory
EPA: Not subject to any special EPA regulations
EU Regulations: Not classified as hazardous under Regulation (EC) No 1272/2008 (CLP)
Other National Regulations: Check compliance with country-specific laws where used or exported
Labeling Requirements: Good practice recommends ingredient disclosure and safe handling instructions even if not hazardous
