Supplier Information: Available through distributors of laboratory chemicals and industrial oils
Emergency Contact: Refer to local poison control, fire department, or emergency services
GHS Classification: Not considered hazardous under GHS criteria for most uses
Physical Hazards: Slippery when spilled; can cause falls
Health Hazards: Aspiration hazard if swallowed; may cause lung injury; repeated skin contact may result in mild irritation
Environmental Hazards: Spillage can affect aquatic environments by forming a surface film
Pictograms: Typically not required for Liquid Paraffin, but respiratory hazard symbol applies in case of aspiration hazard
Chemical Identity: Liquid Paraffin
Purity: Typically over 99% mineral oil (mixture of saturated hydrocarbons)
Additives: Cosmetic or pharmaceutical grades may include stabilizers
Impurities: Highly refined, limited contaminants in regulated products
Other Ingredients: Minor unsaturated aliphatic and cyclic hydrocarbons may be present in trace amounts
Inhalation: Remove the individual to fresh air; seek medical attention if symptoms like coughing or difficulty breathing appear
Skin Contact: Wash thoroughly with soap and water; remove contaminated clothing
Eye Contact: Flush the eyes gently with water for at least 15 minutes; consult an eye specialist if irritation remains
Ingestion: Do not induce vomiting because aspiration into lungs can be dangerous; get medical advice if swallowed
Important Symptoms: Product aspirated into lungs may cause chemical pneumonitis
Medical Attention: Direct assessment by a healthcare provider improves outcome for accidental swallowing or persistent irritation
Suitable Extinguishing Media: Use foam, carbon dioxide, dry chemical powder, or water spray
Unsuitable Extinguishing Media: Avoid using water jets directly because of risk of spreading
Specific Hazards: Gives off irritating and toxic fumes during incomplete combustion, such as carbon monoxide
Protective Equipment: Firefighters should use full protective gear and self-contained breathing apparatus
Firefighting Tactics: Isolate hazardous area; keep unnecessary personnel away;
Thermal Decomposition: Release of hydrocarbons and smoke possible at high temperatures
Personal Precautions: Prevent slips and falls; use gloves and safety goggles when cleaning up
Environmental Precautions: Prevent entry into drains, sewers, and surface water to avoid contamination
Methods For Clean-Up: Absorb spill with sand, earth, or other inert substance; collect in properly labeled containers for disposal
Decontamination: Wash area thoroughly with water and detergent after cleanup
Special Cleanup: Avoid creating mist; ventilate contaminated area well during removal
Handling: Use proper lifting techniques when handling containers; prevent eye and skin contact
Precautions: Provide good ventilation; avoid breathing product mist or vapors
Safe Storage: Store in tightly closed containers; keep away from heat, sparks, or open flames
Storage Temperature: Maintain at ambient room temperature; protect from direct sunlight
Compatible Materials: Store away from strong oxidizers, acids, or alkalis to prevent degradation or reaction
Other Guidance: Use only purpose-designed containers; label storage area according to contents
Exposure Limits: Occupational exposure limits are not established for pure Liquid Paraffin, but minimize repeated inhalation or direct skin contact
Engineering Controls: Employ local exhaust ventilation where significant mist generation occurs
Personal Protective Equipment: Use rubber or nitrile gloves, safety glasses, and protective footwear
Respiratory Protection: Where mist or vapor may form, use a properly fitted, approved respirator
Hygiene Measures: Wash hands after handling; avoid eating, drinking, or smoking near the product
Environmental Exposure: Implement measures to prevent environmental release during handling
Appearance: Clear, odorless, oily liquid
Odor: Mild or absent
Density: Around 0.82–0.88 g/cm³ at 20°C
Melting Point: Below −24°C; remains a liquid at room temperature
Boiling Point: Above 300°C
Solubility: Insoluble in water; soluble in chloroform, ether, some organic solvents
Viscosity: Refined product has variable viscosity depending on grade; generally viscous
Flash Point: Above 180°C (closed cup method)
Auto-Ignition Temperature: About 330°C
Partition Coefficient (n-octanol/water): High, lipophilic nature
Chemical Stability: Good stability under recommended storage and use conditions
Incompatible Materials: Strong oxidizing agents—these may cause hazardous decomposition
Hazardous Decomposition: Carbon monoxide, carbon dioxide, and smoke can develop if overheated
Polymerization: Not known to occur
Reactivity: Normally unreactive; no reported violent reactions
Acute Toxicity: Not classified as acutely toxic by oral, dermal, or inhalation routes for refined grades
Skin Irritation: Prolonged or repeated contact can lead to mild irritation
Eye Irritation: May cause mild, transient irritation
Inhalation Risk: Mists can irritate the respiratory tract
Chronic Exposure: Continuous skin exposure may result in dermatitis
Aspiration Hazard: Severe lung damage possible if product is aspirated during vomiting
Carcinogenic Effects: Highly refined mineral oils are not classified as carcinogenic; untreated or mildly-treated grades show some risk
Ecotoxicity: Not readily biodegradable; may persist in the environment
Aquatic Toxicity: Forms a film on water surfaces; can impact oxygen transfer and harm aquatic organisms
Soil Mobility: Low volatilization; potential for accumulation in soil
Bioaccumulation: Unlikely to bioaccumulate due to inert properties, but persistent
Degradability: Biodegradation occurs slowly in natural environments
Waste Handling: Collect product and contaminated materials for disposal at a licensed facility
Environmental Disposal: Prevent entry into water sources and soil
Residue Disposal: Rinse containers before recycling or proper chemical disposal
Disposal Regulations: Follow local, regional, and national regulations for hazardous and non-hazardous waste
Recycling Options: Some industrial centers accept used mineral oil for energy or recovery
UN Number: Not regulated under most international transport regulations
Transport Hazard Class: Not applicable
Packing Group: Not classified
Special Transportation Measures: Use tight-sealing, robust containers; protect from moisture and physical damage
Labelling Requirements: None typically mandated for highly refined grades
Labeling & Classification: Exempt from certain hazard labeling due to low toxicity; varies by jurisdiction
Occupational Guidelines: OSHA and EU agencies set best practice guidelines for handling mineral oil mists
Chemical Inventories: Listed in U.S. TSCA, European EINECS/ELINCS, Canadian DSL
