Chemical Name: Zinc Naphthenate
Appearance: Oily, dark green or brown liquid
Odor: Strong, petroleum-like aroma
Typical Use: Wood preservative, fungicide
Solubility: Limited in water, high in organic solvents
CAS Number: 12001-85-3
GHS Classification: Skin irritant, eye irritant, potential aquatic hazard
Hazard Statements: Causes moderate skin and eye irritation, may be harmful if inhaled or swallowed, toxic to aquatic life
Pictograms: Exclamation mark, environment
Target Organs: Skin, eyes, respiratory system, central nervous system
Burn Risk: Not a major fire risk, but can emit toxic fumes when burned
Chronic Exposure: Repeated skin contact may cause dermatitis
Active Ingredient: Zinc naphthenate (approx. 8–20 percent by weight)
Carrier Solvents: Mineral spirits, petroleum distillates
Minor Components: Naphthenic acids, trace impurities from crude oil
Additional Zinc Compounds: Minute proportions due to manufacturing process
Inhalation: Move affected person to fresh air quickly, provide oxygen if respiratory difficulty continues
Skin Contact: Wash exposed area thoroughly with soap and water; take off contaminated clothing
Eye Contact: Flush eyes under running water for at least 15 minutes; seek medical attention if irritation lingers
Ingestion: Rinse mouth, do not induce vomiting unless told by medical professionals
Note to Physicians: Treat based on symptoms; monitor respiratory and nervous system
Suitable Extinguishing Media: Foam, carbon dioxide, dry chemical
Unsuitable Media: Direct water stream could spread product
Hazards: Vapors heavier than air may travel along ground
Combustion By-products: Zinc oxides, carbon monoxide, sulfur compounds
Protective Gear: Full protective gear including self-contained breathing apparatus
Firefighting Approach: Cool containers with water spray, keep away from runoff to water bodies
Personal Precautions: Wear chemical-resistant gloves and goggles, avoid breathing vapors
Spill Response: Absorb with sand, clay, or absorbent pads; shovel into disposal containers
Environmental Precautions: Prevent entry into waterways and soil
Cleanup: Ventilate area well, wipe up residue using solvent, dispose as hazardous waste
Handling: Always work in well-ventilated areas, avoid direct contact with liquid
Storage Requirements: Store away from heat and open flames, avoid direct sunlight, keep containers tightly closed
Incompatible Materials: Strong oxidizers, acids
Safe Practice: Label all storage containers, keep above freezing temperature to prevent phase separation
Engineering Controls: Use local exhaust ventilation or fume hoods to reduce airborne concentration
Respiratory Protection: Use a respirator if exposure exceeds recommended levels
Skin Protection: Wear gloves made of nitrile or neoprene
Eye Protection: Use chemical splash goggles
Clothing: Long sleeves, lab coat, and closed footwear recommended
Physical State: Viscous liquid
Color: Green to brown
Odor Threshold: Detectable at low concentrations
Boiling Point: Approximately 150-220°C depending on formulation
Melting Point: Below -10°C
Density: Around 0.9–1.1 g/cm³
Vapor Pressure: Low at room temperature
Flash Point: Typically above 60°C, varies by solvent
Solubility in Water: Minimal
Partition Coefficient: Aligned with high hydrophobicity; tends to aggregate in soils and fats
Chemical Stability: Stable under normal handling and storage conditions
Reactivity: May react with strong acids, bases, and oxidizers
Hazardous Polymerization: Not expected to occur
Breakdown Products: Metal oxides and organic acids from combustion or extreme heat exposure
Acute Toxicity: Moderate if ingested or absorbed; symptoms may include nausea, vomiting, headaches
Chronic Effects: Possible skin sensitization and central nervous system effects with prolonged exposure
Carcinogenicity: Not classified as a carcinogen
Mutagenicity: Insufficient evidence for genetic impact
Routes of Exposure: Skin contact, inhalation, ingestion
Special Population Risk: Pregnant women, children, those with preexisting skin or respiratory conditions could experience heightened effects
Aquatic Toxicity: High toxicity to aquatic invertebrates and fish
Persistence: Tends to bind with soil and sediment
Bioaccumulation Potential: Present, especially in aquatic environments
Soil Mobility: Low; product rarely migrates far from the spill area
Degradability: Slowly breaks down under sunlight and bacterial action over time
Disposal Methods: Incinerate at approved facilities, follow local hazardous waste regulations
Container Disposal: Triple rinse prior to recycling or controlled landfill
Waste Restrictions: Do not discharge into drains, surface water, or soil
Special Precautions: Notify disposal facility if product is contaminated or mixed
UN Number: Regulated as a hazardous material when shipped in bulk
Hazard Class: Flammable liquid depending on carrier solvent
Packing Group: Varies depending on formulation; bulk containers require secondary containment
Shipping Restrictions: Avoid transportation near incompatible chemicals
Emergency Response: Spill kit and fire extinguishers should be readily available during large shipments
OSHA: Covers zinc naphthenate under hazardous chemical laws
EPA: Registration required for pesticidal use, specific rules apply for discharge and runoff
TSCA: Listed as an existing chemical, subject to reporting
DOT: Shipment regulations based on flammability and aquatic hazard
Additional Requirements: State-specific reporting may be necessary; safety plans recommended for workplaces using sizable quantities
