Chemical Name: Zinc Glycinate
CAS Number: 14281-83-5
Concentration: 98–100% (Pure)
Impurities: Trace amounts of water, unbound glycine, zinc oxide
Eye Contact: Rinse cautiously with water for up to 15 minutes, holding eyelids open. Remove contact lenses if present and easy to do.
Skin Contact: Wash with plenty of soap and water. Remove contaminated clothing. Seek medical attention if irritation persists.
Inhalation: Move to fresh air. If breathing difficulties continue, get medical advice.
Ingestion: Rinse mouth. Do not induce vomiting. Seek medical attention for any persistent discomfort or unusual symptoms.
Suitable Extinguishing Media: Use dry chemical, water spray, foam, or carbon dioxide. Select agents based on surrounding materials.
Specific Hazards: Decomposition in fire may create zinc oxides, carbon oxides, nitrogen oxides.
Protective Equipment: Firefighters should wear full protective gear, including self-contained breathing apparatus.
Explosion Risk: No specific explosive properties known for Zinc Glycinate.
Personal Precautions: Avoid contact with skin, eyes, and clothing. Do not breathe dust. Ventilate area.
Environmental Precautions: Prevent large amounts from entering drains, watercourses, or soil.
Cleanup Methods: Sweep up dry powder, avoiding dust creation. Transfer to labeled refuse container. Clean area with water. Dispose according to local regulations.
Handling: Wear appropriate protective gear. Work in well-ventilated spaces. Minimize dust generation.
Storage: Keep container tightly closed in a dry, cool location. Protect from moisture and incompatible materials such as strong oxidizing agents.
Incompatibilities: Strong acids and bases, oxidizing agents.
Specific Uses: Follow recommendations on product label for intended applications.
Exposure Limits: No established OSHA or ACGIH limits for this compound. General dust limits apply; total dust not to exceed 15 mg/m³ (OSHA PEL).
Engineering Controls: Use local exhaust ventilation to reduce airborne dust.
Personal Protective Equipment: Safety goggles, gloves (nitrile or neoprene), lab coat, and a dust mask or particulate respirator if needed.
Hygiene Measures: Wash hands after handling. Remove contaminated clothing.
Appearance: White or slightly off-white crystalline powder

Skin Corrosion/Irritation: Mild potential for irritation on prolonged or repeated contact.
Eye Damage/Irritation: Possible transient irritation.
Respiratory Sensitization: Not expected under standard handling; dust may cause minor mechanical irritation.
Ingestion Effects: Large amounts can cause stomach upset, nausea, or diarrhea, similar to excessive zinc intake.
Chronic Effects: No known chronic toxicity at recommended levels.
Carcinogenicity, Mutagenicity, Reproductive Toxicity: No classification for carcinogenic, mutagenic, or reproductive hazards under current regulatory guidelines.
Target Organ Effects: None identified during normal use.
Ecotoxicity: Zinc compounds display toxicity toward aquatic life at elevated exposures. No acute ecotoxic data available for the chelated form.
Persistence and Degradability: Readily degrades to zinc ions and glycine.
Bioaccumulation: Zinc can bioaccumulate in ecosystems, warranting limited release.
Mobility in Soil: Mobile in water; binds moderately to soil particles.
Other Adverse Effects: Avoid releasing large amounts into waterways.
Waste Treatment Methods: Dispose of as non-hazardous chemical waste per local, regional, and national regulations.
Contaminated Packaging: Empty containers may contain residue — rinse and recycle or dispose of via authorized waste handler.
Special Considerations: Do not dispose into the environment or water sources. Seek local waste facility guidance if uncertain.
