Product Name: White Mineral Oil
Chemical Family: Petroleum Hydrocarbon
CAS Number: 8042-47-5
Synonyms: Paraffinic Oil, Liquid Paraffin
Recommended Use: Cosmetic ingredient, lubricants, food-grade applications, pharmaceuticals
Suppliers: Major chemical distributors, food and pharma supply companies
Contact Information: Emergency support numbers and regional supplier details differ based on location and law.
Classification: Not classified as hazardous under GHS regulations for most grades
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Health Effects: Prolonged or repeated skin contact may cause mild irritation. Inhalation of mist may cause discomfort to respiratory tract. Ingestion in large amounts can result in diarrhea or laxative effects due to oil's nature. Chronic exposure in industrial settings may dry the skin.
Symptoms: Redness, minor skin irritation, coughing from inhalation of mist, upset stomach if consumed in significant quantities
Risk Phrases: May cause minor irritation with direct, prolonged exposure. Oil mist occasionally contributes to minor respiratory effects in poorly ventilated spaces.
Main Constituent: Saturated aliphatic and alicyclic hydrocarbons
Purity: Typically above 99% for high-grade or food/pharma specifications
Impurities: Trace amount of aromatics, sulfur compounds, and additives may appear depending on grade
Additives: Food-grade or medical white mineral oils generally exclude additives, while industrial oils sometimes include stabilizers.
Eye Contact: Rinse with running water for several minutes. Remove contact lenses. Seek medical attention if irritation persists.
Skin Contact: Wash with soap and water. Remove contaminated clothing and wash before reuse. Persistent irritation needs medical attention.
Inhalation: Move person to fresh air. If breathing is difficult, call for emergency medical support. Prolonged exposure to mist can necessitate clinical care if respiratory distress develops.
Ingestion: Rinse mouth thoroughly. Do not induce vomiting. Obtain medical guidance especially in case of accidental ingestion by children.
Extinguishing Media: Foam, dry chemical, carbon dioxide, water spray (use carefully to avoid oil dispersion)
Hazardous Combustion Products: Carbon monoxide, carbon dioxide, and trace smoke may arise in incomplete combustion
Protective Equipment: Firefighters should use self-contained breathing apparatus and protective gear. Runoff from firefighting may pose environmental hazard in water systems.
Fire Hazards: Oil can ignite at high temperatures, generating thick, black smoke. Combustion often leaves slippery residue.
Personal Precautions: Wear chemical-resistant gloves, safety goggles, long sleeves, and boots. Control sources of ignition in affected area.
Environmental Precautions: Prevent entry into sewers, rivers, and water supplies. Absorb spill with inert materials such as sand, earth, or commercial absorbents.
Cleanup Methods: Contain and collect for disposal per local regulations. Clean area with detergent and water after pickup. For large spills, construct dikes to restrict oil migration. Mark area “slippery” until fully decontaminated.
Handling: Ensure proper ventilation. Keep away from heat, sparks, and open flame. Minimize creation of oil mist. Avoid direct skin or eye contact. Wear appropriate personal protective equipment during transfer or processing.
Storage: Store in tightly closed, properly labeled containers away from incompatible materials like strong oxidizers. Keep storage tanks, drums, and containers away from direct sunlight and moisture. Store at temperatures below 40°C to maintain properties. Use vessels constructed of compatible metals such as stainless steel or HDPE.
Engineering Controls: Use local exhaust ventilation to control oil mist in production and transfer areas.
Exposure Limits: OSHA PEL for mineral oil mist: 5 mg/m³ (Time Weighted Average), ACGIH TLV: 5 mg/m³ (TWA)
Personal Protection: Chemical goggles, nitrile or neoprene gloves, laboratory coat or protective apron, and work boots recommended. Where oil mist accumulates above exposure limits, use a properly fitted NIOSH-approved air-purifying respirator.
Appearance: Clear, colorless, oily liquid
Odor: Odorless or very faint hydrocarbon scent, varying by grade
Boiling Point: 260°C – 455°C (500°F – 851°F)
Melting Point: Typically below -24°C (-11°F)
Flash Point: Above 160°C (320°F) closed cup
Autoignition Temperature: About 330°C (626°F)
Vapor Pressure: Negligible at room temperature
Viscosity: Depends on specific grade; often between 34-150 cSt at 40°C
Solubility: Insoluble in water; soluble in most organic solvents
Specific Gravity: 0.82 to 0.88 at 15°C
pH: Not applicable (non-aqueous)
Partition Coefficient (n-octanol/water): High; oil separates easily from water
Stability: Stable under normal temperatures and recommended storage conditions. White mineral oil can degrade slowly when exposed to strong oxidizers.
Reactivity: Reacts with strong oxidizing agents like peroxides, chlorine, or nitric acid which can lead to fire or explosion hazards.
Hazardous Decomposition: Thermally decomposes to emit carbon monoxide, carbon dioxide, and small amounts of low molecular hydrocarbons at high temperatures.
Storage Life: Maintains physical and chemical stability for up to several years if kept in original, sealed packaging away from sunlight.
Acute Toxicity: Practically non-toxic. No significant acute effects from skin or oral exposure at ordinary use levels. High oral doses may cause mild gastrointestinal upset or laxative effect.
Chronic Toxicity: Repeated skin exposure may lead to dryness. Long-term inhalation of mist has resulted in rare, mild respiratory effects in occupational settings.
Carcinogenicity: Not considered carcinogenic by IARC or NTP for the purified, food-grade product. Industrial grades lacking sufficient refining have raised some concerns historically.
Mutagenicity: Not mutagenic according to available data.
Reproductive Effects: No significant evidence of reproductive toxicity.
Aquatic Toxicity: Low toxicity to aquatic life. White mineral oil forms a surface film on water, restricting gas exchange and posing physical hazard to aquatic organisms if spilled in bulk.
Persistence and Degradability: Highly persistent in soil and water due to strong hydrophobicity; degrades very slowly under environmental conditions.
Bioaccumulation: Potential for bioaccumulation within sediments and organisms, particularly in poorly ventilated water bodies.
Mobility in Soil: Low solubility leads to limited mobility except in case of runoff containing emulsified product.
Waste Disposal Methods: Collect and dispose of in accordance with local, state, and federal regulations. Incineration in approved facility recommended if recovery or recycling not practical. Used mineral oil contaminated with other substances may require special handling.
Container Handling: Empty containers retain residue and require proper decontamination before recycling or removal. Puncture or crush to prevent reuse for non-compatible substances.
UN Number: Not classified as hazardous for transport by DOT, IMDG, IATA for refined white mineral oil
Packaging Group: Not regulated
Proper Shipping Name: Not dangerous goods according to international transport guidelines
Special Precautions: Transport in tightly closed, leakproof containers. Oil spills during transport can create significant slip and fire risks on roadways and loading areas.
OSHA Status: Not regulated as a hazardous material under OSHA Hazard Communication Standard for purified oil
TSCA (Toxic Substances Control Act): Listed
EPA Clean Water Act: Oil discharges in the United States regulated as oil spills; must report releases to navigable waters.
FDA Approval: Meets federal requirements for use in food and pharmaceutical applications (specific grades only).
REACH (Europe): Registered and compliant for high purity forms.
SARA Title III: Not listed as a hazardous substance requiring reporting under Superfund Amendments and Reauthorization Act.
