Product Name: Zinc Lactate
Chemical Formula: C6H10O6Zn
CAS Number: 16039-53-5
Synonyms: Zinc(II) lactate, D,L-Lactic acid zinc salt
Recommended Use: Food additive, nutritional supplement, chemical reagent
Supplier Contact Details: Manufacturer or distributor details including address, emergency phone number, and email (refer to product label or purchase documentation)
Classification: Not classified as hazardous according to GHS
Main Hazards: Eye contact may cause irritation. Inhalation of dust may result in mild respiratory tract discomfort. Swallowing large amounts can result in gastrointestinal disturbances. Skin contact generally does not result in serious injury but frequent or prolonged exposure could cause dryness.
Signal Word: None required
Pictograms: None required
Other Hazards: Possible environmental hazard to aquatic organisms if large amounts enter waterways
Chemical Name: Zinc Lactate
CAS Number: 16039-53-5
Concentration: >98% (by weight)
Impurities: Trace elements and moisture content below 2% (typically calcium, magnesium, small organic acids, if any)
Inhalation: Remove individual to fresh air. Seek medical attention if symptoms persist.
Skin Contact: Remove contaminated clothing. Wash affected skin thoroughly with soap and water. Seek advice if irritation continues.
Eye Contact: Rinse immediately with plenty of water for at least 15 minutes, keeping eyelids open. Consult an eye specialist if discomfort remains.
Ingestion: Rinse mouth with water. Seek medical attention for large ingestions or if feeling unwell.
Most Important Symptoms: Mild gastrointestinal upset, irritation of eyes, nose, or skin
Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide
Unsuitable Media: Do not use water jet directly on burning material
Hazardous Decomposition Products: Zinc oxides, carbon oxides, lactate fumes under combustion
Specific Hazards: Product is not flammable or explosive, but fire in proximity may release harmful fumes
Special Firefighting Procedures: Wear self-contained breathing apparatus and full protective gear. Avoid inhalation of decomposition products
Personal Precautions: Use appropriate personal protective equipment, avoid contact with eyes and prolonged skin contact, avoid inhalation of dust
Environmental Precautions: Prevent further leakage or spillage if safe to do so. Do not let product enter drains or watercourses in large quantities
Spill Cleanup Methods: Sweep or scoop up spilled solid. Use damp cloth or mop to decontaminate surface. Store collected material in closed containers for proper disposal. Wash area with water. Avoid generating dust
Handling: Minimize dust formation. Handle in accordance with good chemical hygiene practices. Avoid contact with eyes and long-term skin exposure. Wash hands after use
Storage Conditions: Store tightly sealed in a cool, dry, well-ventilated place, away from moisture, incompatible materials, and direct sunlight. Keep away from food and beverages
Incompatible Materials: Strong acids, strong bases, oxidizing agents
Engineering Controls: Local exhaust ventilation or general room ventilation to minimize dust exposure
Respiratory Protection: Use NIOSH-approved dust mask or respirator if dusting is likely
Eye Protection: Safety goggles or safety glasses with side shields
Skin Protection: Wear suitable protective gloves (e.g., nitrile, latex), long sleeves recommended
Other Protective Equipment: Laboratory coat or apron
Exposure Limits: No specific exposure limit established for zinc lactate. For zinc compounds (as Zn), OSHA PEL is 15 mg/m³ (total dust), ACGIH TLV is 2 mg/m³ (respirable fraction)
Appearance: White or off-white crystalline powder
Odor: Odorless or faint organic smell
Odor Threshold: Not available
pH: 6.5–7.5 (10% solution in water)
Melting Point: Approximately 210°C (with decomposition)
Boiling Point: Not applicable (decomposes before boiling)
Solubility: Freely soluble in water; sparingly soluble in ethanol
Density: 1.89 g/cm³
Partition Coefficient (n-octanol/water): Not determined
Vapor Pressure: Negligible
Evaporation Rate: Not applicable
Chemical Stability: Stable under normal ambient and recommended storage conditions
Reactivity: Not reactive in normal use
Incompatible Materials: Strong acids, strong oxidizers, alkalis
Hazardous Reactions: No hazardous polymerization expected
Conditions to Avoid: Excessive heat, moisture, exposure to strong acids or oxidizers
Decomposition Products: Zinc oxides, carbon oxides, organic vapors
Acute Toxicity: Low acute toxicity. Oral LD50 (rat): > 2000 mg/kg
Skin Corrosion/Irritation: Prolonged contact may cause dryness or mild irritation
Serious Eye Damage/Irritation: May cause mild, reversible irritation
Respiratory or Skin Sensitization: No evidence of sensitization in animal studies or human reports
Chronic Effects: Prolonged excessive intake may result in zinc overload (nausea, vomiting, interference with copper metabolism); not anticipated at normal use levels
Carcinogenicity: Not listed as carcinogen by IARC, NTP, OSHA
Reproductive Toxicity: No toxic reproductive effects reported in available studies
Target Organs: None identified at typical exposure levels
Ecotoxicity: Data for zinc compounds suggest potential toxicity to aquatic life at high concentrations. Low environmental risk in small quantities
Persistence and Degradability: Organic part (lactate) biodegradable; zinc remains as inorganic ion in the environment
Bioaccumulative Potential: Zinc can accumulate in aquatic organisms
Mobility in Soil: Water-soluble, may migrate through soil if released
Other Adverse Effects: Avoid bulk releases to prevent harm to aquatic systems
Waste Treatment Methods: Dispose of in accordance with local, regional, and national regulations. Small quantities can usually be disposed of as non-hazardous laboratory or industrial waste.
Unused Product: If uncontaminated, send for on-site or off-site recycling or recovery
Contaminated Packaging: Rinse thoroughly and dispose of according to regulations
