Classification: Not classified as hazardous under GHS standards
Health Hazards: Dust may irritate eyes, skin, or respiratory tract; inhalation may trigger allergic reactions in some individuals
Environmental Hazards: No significant environmental hazard expected
Label Elements: Signal word not required; precautionary statements emphasize avoiding inhalation and contact with eyes
Other Hazards: Those with enzyme allergies or respiratory conditions watch for exacerbation
Main Ingredient: Lactase enzyme (β-Galactosidase), sourced from Aspergillus oryzae or Kluyveromyces lactis
Concentration: Pure enzyme or mixtures with water, stabilizers, or carrier substances such as maltodextrin; enzyme activity and percentage depend on formulation
Other Components: Fillers and stabilizing agents vary by manufacturer; rarely contain preservatives or anti-caking agents
Impurities: Trace fermentation byproducts may be present in industrial grades
Inhalation: Remove to fresh air; those who develop breathing difficulty should seek medical attention
Skin Contact: Rinse with soap and plenty of water; persistent irritation warrants medical advice
Eye Contact: Rinse gently with water for several minutes; remove contact lenses if used; consult a physician if symptoms persist
Ingestion: Product considered of low acute toxicity; rinse mouth and drink water; seek advice if symptoms arise
Symptoms & Effects: Watch for allergic responses like rash, breathing issues, or swelling in sensitive individuals
Suitable Extinguishing Media: Water spray, dry chemical, foam, or carbon dioxide
Unsuitable Extinguishing Media: None identified for this product
Hazards from Combustion: Decomposition at high temperatures may produce CO, CO₂, and organic byproducts
Protective Equipment: Wear self-contained breathing apparatus and protective gear
Advice for Firefighters: Avoid inhalation of combustion gases, use water spray to cool nearby containers
Personal Precautions: Wear dust mask, gloves, eye protection
Environmental Precautions: Minimize dust generation; avoid discharge into drains
Containment & Cleanup: Sweep or vacuum spilled material, place in suitable container for disposal; moisten to reduce dust
Decontamination: Wash contaminated area with water after collecting material
Disposal: Dispose in accordance with local regulations
Handling Procedures: Use only in well-ventilated areas, avoid creating dust; handle with dry, clean utensils
Technical Measures: Install local exhaust ventilation in areas of heavy use
Safe Storage Conditions: Store in tightly sealed original containers in a dry, cool location, avoiding heat, moisture, or direct sunlight
Incompatible Materials: Oxidizing agents, strong acids or bases
Hygienic Practices: Wash hands and exposed skin after handling; do not eat, drink, or smoke nearby
Control Parameters: No occupational exposure limits established for lactase
Engineering Controls: Provide adequate local exhaust in processing locations
Personal Protective Equipment (PPE): Respiratory masks to limit dust, safety goggles, gloves, protective clothing
General Protection: Use standard safety practices in enzyme and powder handling
Recommendations for Sensitive Workers: Respirator with particulate filter recommended for prolonged or repeated exposure
Appearance: Off-white to light beige powder or crystalline granules
Odor: Slight or none
Odor Threshold: Not determined
pH: 4.0 to 7.0 for aqueous solutions
Melting Point/Freezing Point: Not applicable (enzyme decomposes before melting)
Boiling Point/Range: Not applicable (solid enzyme preparation)
Solubility: Readily disperses or partly dissolves in water
Vapor Pressure: Not relevant for solid
Bulk Density: Approximately 0.5–0.8 g/cm³, varies with formulation
Decomposition Temperature: >60°C may lead to enzyme denaturation
Partition Coefficient (n-octanol/water): Not determined
Flash Point: Not applicable (non-flammable solid)
Stability: Stable under recommended storage conditions; moisture and high temperatures degrade potency
Hazardous Reactions: No dangerous reactions expected under normal handling
Conditions to Avoid: Exposure to moisture, high humidity, heat, and direct sunlight
Incompatible Materials: Strong oxidizers may degrade enzyme, avoid strong acids/bases during formulation
Hazardous Decomposition: Oxides of carbon and nitrogen, minor organic compounds under fire conditions
Acute Toxicity: Low toxicity in animal studies; LD₅₀ values typically above regulatory concern
Skin Corrosion/Irritation: May cause mild irritation in sensitive individuals after prolonged contact
Eye Damage/Irritation: Temporary discomfort with dust exposure to eyes possible
Respiratory Sensitization: Inhalation may lead to allergic sensitization in predisposed persons
Mutagenicity/Carcinogenicity: Negative in standard tests; not considered carcinogenic
Repeated Dose Toxicity: No adverse effects seen in dietary enzyme studies up to high concentrations
Other Effects: Occupational asthma cases rare; monitor respiratory health in regular users
Ecotoxicity: Non-toxic to aquatic life in practical concentrations; enzyme breaks down to amino acids and sugars
Persistence and Degradability: Readily biodegradable in natural environments
Bioaccumulative Potential: Not predicted to bioaccumulate due to enzyme’s protein nature
Mobility in Soil: High; enzyme diffuses in water, binds to soil particles, or is degraded by microorganisms
Other Adverse Effects: None expected from standard use or accidental release; environmental monitoring in food use unnecessary
Recommended Disposal Methods: Dispose of according to federal, regional, and local waste regulations; place in suitable landfill or approved incineration facility
Diluted Wastes: Small volumes may be washed down drains with plenty of water unless local rules advise otherwise
Packaging Disposal: Recycle clean packaging; dispose of contaminated packaging as solid chemical waste
Precautions for Landfill or Incineration: Avoid releasing dust; incineration under controlled conditions recommended for bulk disposal
Special Procedures: Follow specific institutional or community protocols for food enzyme or biological waste handling
UN Number: Not regulated for transport
UN Proper Shipping Name: Not applicable for lactase preparations
Transport Hazard Class: Non-hazardous for air, sea, and land transport
Packing Group: Not required
Special Precautions: Protect from humidity and moisture in transit; keep containers tightly closed
Environmental Hazards for Transport: No marine pollutant label required
Status Under Chemical Inventories: Food-grade lactase approved for food processing use by FDA, EFSA, and comparable agencies
GHS Classification: Not considered hazardous
Labelling Requirements: Ingredient disclosure per local food and chemical safety laws
Occupational Controls: None specific for casual use; follow general industrial guidelines for powders
Restrictions: Use as directed in food, supplement, or industrial enzyme formulations according to jurisdiction
Other Regulatory References: Check national and state-level guidance for workplace or consumer exposure rules
