Chemical Name: Butyl Lactate
Common Uses: Solvent in paints, coatings, inks, and cleaning products; also found in some flavors and fragrances
Appearance: Clear, colorless to pale yellow liquid with a mild odor
Chemical Formula: C7H14O3
CAS Number: 138-22-7
Classification: Not listed as a hazardous substance under GHS but can cause moderate eye and skin irritation
Main Hazards: May cause respiratory, skin, and eye irritation; inhalation or ingestion can result in discomfort or health effects
Environmental Danger: Spills can harm aquatic environments
Fire Risk: Flammable at high concentrations or temperatures
Main Ingredient: Butyl Lactate, usually over 97 percent purity
Impurities: Trace amounts of related esters or acids, based on production
Additives: Sometimes contains stabilizing agents to prevent degradation
Inhalation: Move to fresh air, seek help if symptoms persist
Skin Contact: Wash thoroughly with soap and water, remove contaminated clothing
Eye Contact: Rinse gently with running water for several minutes, remove contact lenses if present
Ingestion: Rinse mouth, drink water, avoid inducing vomiting, get medical advice if large amounts swallowed
Suitable Extinguishing Media: Alcohol-resistant foam, dry powder, carbon dioxide, water spray
Hazardous Combustion Products: May release toxic fumes including carbon monoxide and carbon dioxide
Firefighting Advice: Wear self-contained breathing apparatus, keep containers cool by spraying with water
Special Risks: Vapors are heavier than air, can move along floors and ignite at distant ignition points
Precaution: Keep people without adequate protection away
Containment: Stop leak if it can be done safely, absorb with inert material like sand or earth
Clean-up: Use tools that do not produce sparks, ventilate the area
Disposal: Place contaminated material in suitable closed containers for disposal
Handling: Use only in well-ventilated areas, avoid contact with eyes, skin, and clothing
Personal Precaution: Keep away from ignition sources, avoid buildup of vapors
Storage: Store in tightly sealed containers, place in a cool, dry area away from direct sunlight and incompatible materials like acids or oxidizers
Spill Prevention: Use secondary containment and proper labeling for all storage vessels
Engineering Controls: Use local exhaust ventilation; keep levels below recommended exposure limits
Personal Protective Equipment: Chemical-resistant gloves, safety goggles, protective clothing
Respiratory Protection: Use an approved respirator in poorly ventilated areas
Hygiene:** Wash hands after handling, do not eat or smoke during use, change clothing if contaminated
Appearance: Clear liquid, mild odor
Boiling Point: About 185°C
Solubility: Fully miscible in water
Vapor Pressure: Low at room temperature
Density: 1.03 g/cm³
Pours Easily: Flows readily at room temperature, does not solidify under normal storage
Chemical Stability: Stable in normal storage conditions
Reactive Materials: Incompatible with strong acids, bases, and oxidizers
Decomposition: Produces hazardous fumes and gases if heated above its decomposition temperature
Polymerization: Does not undergo hazardous polymerization under standard conditions
Routes of Exposure: Inhalation, ingestion, skin or eye contact
Effects on Health: Short-term exposure may cause irritation to skin, eyes, lung tissues; large doses may cause digestive discomfort
Chronic Exposure: No strong evidence links it to long-term health risks under recommended limits
Sensitization: No known cases of allergic sensitization under occupational use
Mobility: Spreads in water, low potential for bioaccumulation
Aquatic Toxicity: Harmful to aquatic life at high concentrations; can damage fragile pond and stream ecosystems if not contained
Persistence: Decomposes relatively quickly, but repeated spills can still harm water quality
Soil Impact: Breaks down over time but can impact soil organisms if not remediated
Waste Disposal: Treat as chemical waste; local hazardous waste guidelines apply
Reuse and Recycling: Containers should not be reused unless professionally cleaned
Incineration: Best handled by professional hazardous waste incineration
Environmental Protection: Avoid discharge into sewers or waterways, prevent soil contamination through best management practices
Shipping: Kept in leak-proof, clearly labeled containers during transport
Transport Risks: Keep away from heat, open flames, and incompatible substances
Regulated Transport: Generally not regulated as hazardous for ground and sea shipping under standard thresholds
Accident Protocol: Emergency response plans should address spill containment and fire control
Occupational Limits: Not covered by an OSHA-specific permissible exposure limit in the United States yet still recommended to keep exposures as low as practical
Labeling: GHS-compliant labeling includes hazard pictograms and safety phrases
International: Listed in chemical inventories in many countries; subject to local environmental discharge and occupational safety laws
Community Right-to-Know: Facilities handling large volumes often required to report under federal or state chemical inventory laws for transparency and emergency response planning
