Other Ingredients: Exact composition can vary, check for solvents such as hydrocarbons if diluted or shipped as a solution
Hazardous Components: As above, consider possible naphthenic acid vapor or contaminated dust exposure
Inhalation: Move person to fresh air, keep warm and at rest, seek medical attention if symptoms develop or persist
Skin Contact: Remove contaminated clothing, rinse skin immediately with plenty of running water and soap for at least 15 minutes, consult doctor if irritation persists
Eye Contact: Rinse eyes cautiously with water for several minutes, remove contact lenses if present and easy to do, continue rinsing, get medical attention immediately
Ingestion: Rinse mouth with water, do not induce vomiting, call a doctor or poison center straight away, symptoms such as abdominal pain, nausea, or vomiting should receive prompt care
Suitable Extinguishing Media: Carbon dioxide, foam, dry chemical powder, water fog
Unsuitable Extinguishing Media: Do not use water jet as it may spread the fire
Specific Hazards: Fumes containing oxides of carbon and calcium compounds may form, material can be slippery when spilled
Protective Equipment: Full protective gear and self-contained breathing apparatus for fire crews
Firefighting Instructions: Move containers away from flames if safe, stay upwind, apply cooling water to containers exposed to flames, control run-off
Personal Precautions: Remove all sources of ignition, evacuate all non-essential personnel, use personal protective equipment that includes gloves, safety goggles, and dust mask
Environmental Precautions: Prevent spilled material from entering sewers, drains, water courses, or soil, alert local authorities if environmental contamination occurs
Methods for Cleanup: Use inert absorbent such as sand or earth to soak up the substance, shovel the collected material into suitable containers for disposal, clean residue with soap and water, ventilate area thoroughly
Disposal: Dispose of collected waste in accordance with local, regional, and national regulations; contaminated materials may be hazardous
Safe Handling: Avoid ingestion, skin and eye contact, do not inhale fumes or dust, use only with proper ventilation, keep work surfaces clean, avoid smoking or eating near working area
Hygiene Practices: Wash hands before eating, drinking, or smoking; remove contaminated clothing and protective equipment before entering common areas
Storage Conditions: Store in tightly closed, clearly labeled original containers; keep in a cool, dry, well-ventilated location away from strong acids, oxidizers, and direct sunlight; temperature fluctuations may destabilize product
Engineering Controls: Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure limits
Respiratory Protection: Appropriate mask or respirator based on concentration and exposure (consult national standards)
Skin Protection: Nitrile, neoprene, or PVC gloves, long sleeves, chemical-resistant clothing
Eye Protection: Safety glasses with side shields, goggles, or face shield
Workplace Monitoring: Regular checks for airborne dust or vapor; ensure safety showers/eyewash stations remain accessible
Occupational Exposure Limits: No OSHA PEL or ACGIH TLV for calcium naphthenate itself, but watch out for nuisance dust limits and any hydrocarbons involved
Appearance: Brownish, viscous liquid or solid, may have faint petroleum odor
Odor: Faint hydrocarbon and organic acid
pH: Slightly alkaline in aqueous suspension
Boiling Point: Decomposes before boiling, >250°C for main components
Melting Point: Variable (depends on acid chain length and degree of neutralization, but often above 100°C)
Solubility: Very low in water, high in organic solvents
Flash Point: 200°C or higher, always check supplier data
Density: 1.0–1.2 g/cm³, substance-dependent
Vapor Pressure: Very low, can produce some airborne particles during agitation
Autoignition Temperature: Not well characterized, likely above 250°C
Viscosity: Thick and sticky
Partition Coefficient: High, tends to stay in organic phase rather than water
Chemical Stability: Stable under recommended handling and storage; long exposure to high temperatures or strong sunlight can degrade product
Hazardous Reactions: Contact with strong acids releases naphthenic acids; strong oxidizers may cause combustion
Conditions to Avoid: Excessive heat, sparks, open flames, and static discharge, mixing with incompatible chemicals
Incompatible Materials: Strong oxidizing agents, acids
Hazardous Decomposition Products: Thermal decomposition gives carbon oxides, calcium oxide, hydrocarbons, and possibly irritant organic vapors
Routes of Exposure: Inhalation, ingestion, skin, and eye contact
Acute Effects: Moderately toxic if swallowed, irritates skin and mucous membranes, causes severe eye irritation
Chronic Exposure: Prolonged or repeated exposure may result in skin sensitization or dermatitis
Sensitisation: Not considered a strong allergen, but frequent contact can exacerbate symptoms
Carcinogenicity: Ingredients not listed as carcinogen by IARC, NTP, or OSHA, though impurities should always be considered
Target Organs: Respiratory tract, eyes, skin, gastrointestinal system
Symptoms: Irritation, redness, swelling, coughing, abdominal pain, headache with high exposure; monitor unusual symptoms and consult toxicology resources for more specific data
Environmental Impact: Toxic to aquatic life with long lasting effects due to persistence and bioaccumulation potential in soil and sediments
Persistence and Degradability: Tends to degrade slowly, may persist in the environment
Mobility: Low water solubility but can move with suspended solids into waterways
Bioaccumulation: Possible bioaccumulation in aquatic and soil organisms
Aquatic Toxicity: LC50 (fish, 96h): Estimated values range 1-10 mg/L depending on composition
Other Adverse Effects: Forms insoluble residues, may impact flora and fauna in rivers and coastal areas, can alter bacterial communities
Waste Treatment Methods: Collect and package waste in sealed, labeled containers
Disposal Methods: Consult regulatory agencies, often handled as hazardous waste by incineration or secure landfill
Contaminated Packaging: Do not reuse, thoroughly clean or send to approved reconditioner or disposal
Special Precautions: Avoid release to environment, keep away from municipal sewers and unauthorized dumping
Regulations: Adhere strictly to local, regional, and national disposal regulations due to aquatic toxicity and persistence
