White Spirit Specification Table
Key physical and chemical properties of commercial White Spirit. Specifications may vary by grade (Low Aromatic, Regular, High Flash) and producer. The table below represents typical commercial White Spirit ranges.
| Parameter | Typical Range | Unit | Notes |
|---|---|---|---|
| Appearance | Clear, bright liquid | — | Free of sediment, suspended matter, haze, and visible water. Visual clarity is an important quality indicator — any haze or cloudiness suggests contamination or improper storage. |
| Color (Saybolt) | +25 to +30 | Saybolt | Per ASTM D156. White Spirit should be water-white. A Saybolt +25 minimum is typical. Lower values (yellowish tint) may indicate oxidation, contamination, or higher aromatic content. |
| Density @ 15°C | 0.750 – 0.820 | g/cm³ | Per ASTM D4052. Density varies with aromatic content — higher aromatic White Spirit has higher density. Low aromatic grades typically range 0.750–0.780 g/cm³. |
| Flash Point | 30 – 65 | °C | Per ASTM D93 (closed cup). Flash point is grade-dependent: Regular White Spirit ≈ 30–40°C; High Flash White Spirit ≈ 55–65°C. Flash point is the most important safety specification for storage, handling, and transport classification. |
| Distillation — IBP | 140 – 160 | °C | Per ASTM D86. Initial Boiling Point marks the start of the distillation. Low IBP indicates the presence of lighter, more volatile hydrocarbons that affect evaporation rate and flash point. |
| Distillation — FBP | 190 – 220 | °C | Per ASTM D86. Final Boiling Point marks the end of distillation. Higher FBP can leave residual solvent on surfaces. The distillation range (IBP to FBP) determines evaporation rate and application suitability. |
| Distillation — 50% Recovery | 160 – 185 | °C | Per ASTM D86. The 50% recovery temperature is a good indicator of mid-range volatility and overall evaporation behavior. Important for formulators optimizing drying time in coatings. |
| Aromatic Content | < 1% to 20% | % vol | Per ASTM D1319 or GC. Grade-dependent: Low Aromatic / De-aromatized = < 1% (preferred for low-odor, low-toxicity applications); Regular = 15–20% (higher solvency for certain resins and coatings). |
| Sulfur Content | ≤ 10 (Low Aromatic); ≤ 50 (Regular) | mg/kg (ppm) | Per ASTM D5453. Low aromatic grades have very low sulfur after hydrotreating. Sulfur can cause odor, corrosion, and catalyst poisoning in downstream processes. |
| Evaporation Rate | 0.10 – 0.15 (relative to n-BuAc = 1.0) | Relative | Evaporation rate is critical for application performance — determines drying time for paints and coatings, and solvent retention in cleaning processes. White Spirit is classified as a medium-evaporating solvent. |
| Odor | Low to mild | — | Low aromatic grades have very low, near-neutral odor — important for indoor applications and consumer products. Higher aromatic grades have a more pronounced hydrocarbon odor characteristic of petroleum solvents. |
| Water Content | ≤ 200 | mg/kg (ppm) | Per ASTM D6304. Low water content prevents haze, corrosion in storage, and formulation issues in moisture-sensitive coatings and manufacturing processes. |
| Aniline Point | 60 – 75 | °C | Per ASTM D611. Mixed aniline point indicates solvency power — lower values indicate stronger solvency for certain resins, oils, and elastomers. Low aromatic grades have higher aniline points. |
| Kauri-Butanol Value (KB) | 28 – 40 | — | Per ASTM D1133. KB value measures relative solvency power. Regular White Spirit (KB ≈ 35–40) has stronger solvency. Low aromatic grades (KB ≈ 28–33) have moderate solvency — adequate for most common applications. |
| Copper Corrosion (3h @ 50°C) | ≤ Class 1 | — | Per ASTM D130. Ensures White Spirit does not corrode copper, brass, or bronze components in application equipment, storage containers, and processing machinery. |

Key White Spirit Parameters Explained
Understanding the most important White Spirit specification parameters and their practical significance for industrial applications.
Flash Point (30–65°C by Grade)
Flash point is the single most important safety specification for White Spirit. It determines the product's fire hazard classification, storage requirements, transportation regulations, and safe handling procedures.
Why Flash Point Matters:
- ▸Safety Classification: Regular White Spirit (flash point 30–40°C) is classified as a flammable liquid (Class IC). High Flash White Spirit (flash point ≥ 55°C) is classified as combustible — significantly safer and subject to less stringent regulations.
- ▸Storage Implications: Low flash point White Spirit requires flame-proof electrical equipment and enhanced ventilation in storage areas. High Flash White Spirit (≥ 55°C) can be stored under less restrictive conditions — a meaningful operational advantage.
- ▸Transportation: Flash point determines dangerous goods classification (Class 3, Packing Group II or III) under IMDG, ADR, and IATA regulations. Higher flash point simplifies transport documentation and reduces shipping costs.
- ▸Application Selection: High Flash White Spirit is preferred for applications involving elevated temperatures, enclosed spaces, or where fire risk must be minimized. Regular flash point is adequate for well-ventilated industrial settings.
Aromatic Content (< 1% to 20%)
Aromatic content is the defining characteristic that distinguishes White Spirit grades and determines their solvency, odor, toxicity profile, and environmental impact. Aromatics (primarily C7–C9 alkylbenzenes) are naturally present in the crude oil fractions from which White Spirit is produced.
Why Aromatic Content Matters:
- ▸Solvency: Aromatics provide stronger solvency for certain resins, polymers, and oils. Regular White Spirit (15–20% aromatics) dissolves a wider range of materials than Low Aromatic grades (< 1% aromatics). Important for paint and coating formulators.
- ▸Odor & Health: Aromatics contribute to the characteristic hydrocarbon odor and have higher toxicity than aliphatic hydrocarbons. Low Aromatic White Spirit has very low odor and is preferred for indoor applications, consumer products, and applications with worker exposure.
- ▸Environmental: Aromatics have higher photochemical reactivity (smog formation potential). Low Aromatic White Spirit is preferred where VOC regulations are stringent. Many jurisdictions mandate Low Aromatic grades for certain applications.
- ▸Evaporation: Aromatics evaporate more slowly than comparable aliphatic hydrocarbons. Higher aromatic White Spirit has a slightly slower evaporation rate — relevant for drying time in paint and coating applications.
Distillation Range (IBP 140–160°C, FBP 190–220°C)
The distillation range defines the evaporation behavior of White Spirit — the most important performance characteristic for paint, coating, and cleaning applications. A narrower distillation range provides more consistent evaporation behavior.
Why Distillation Range Matters:
- ▸Evaporation Behavior: The distillation range directly determines how quickly White Spirit evaporates from a paint film, coating, or cleaned surface. The IBP sets the initial evaporation rate; the FBP determines whether residual solvent remains.
- ▸Application Suitability: Fast-drying applications (printing inks, some cleaning processes) prefer White Spirit with lower IBP/FBP for rapid evaporation. Slower-drying applications (brush-applied paints) prefer higher IBP/FBP for extended working time.
- ▸Film Formation: In paints and coatings, the solvent must evaporate at the right rate — too fast causes poor film formation and brush marks; too slow delays handling and recoating. The 50% recovery point is a good predictor of overall drying behavior.
- ▸Consistency: Narrow distillation range White Spirit (e.g., 150–190°C) provides predictable, consistent evaporation. Wide-range products may contain both fast and slow evaporating fractions, leading to inconsistent application performance.
Density (0.750–0.820 g/cm³)
Density is a fundamental physical property that affects product handling, commercial transactions, and formulation calculations. White Spirit density correlates with aromatic content — higher aromatic grades have higher density.
Why Density Matters:
- ▸Commercial Transactions: White Spirit is typically sold by volume (liters, drums) or weight (metric tonnes). Accurate density measurement at 15°C is essential for volume-to-weight conversion in commercial transactions.
- ▸Formulation: Paint and coating formulators use density in recipe calculations. Consistent density ensures consistent product quality. Unexpected density variation can indicate batch inconsistency.
- ▸Product Handling: Density determines how White Spirit behaves in storage — it is lighter than water and will float on top of any water present in tanks. This property is used for water separation in storage.
- ▸Quality Indicator: Density outside the typical range can indicate contamination, improper distillation, or mislabeling of product grade. Regular density measurement is a simple and effective quality check.

Drums & IBCs
For smaller volumes, White Spirit is packaged in steel drums (typically 200-liter) or Intermediate Bulk Containers (IBCs, 1,000-liter). Drums and IBCs should be stored in well-ventilated areas away from ignition sources, direct sunlight, and extreme temperatures. Proper labeling per GHS/CLP regulations is required.
Marine Transportation
White Spirit is transported internationally by chemical/product tankers with coated cargo tanks. As a flammable liquid (Class 3, Packing Group II or III depending on flash point), it requires cargo segregation, ventilation, and safety equipment per IMDG Code. Vessel sizes range from 5,000 to 40,000 DWT depending on trade route.
Export Logistics
Standard White Spirit export logistics include: production terminal loading, vessel or container booking, independent surveyor supervision during loading, quality sampling, documentation preparation, customs clearance, and vessel departure. Containerized shipments in flexitanks or ISO tanks are common for smaller volumes.
Safety Handling
White Spirit is a flammable/combustible liquid. Key safety protocols include: grounding and bonding during transfer, no smoking or open flames, adequate ventilation, personal protective equipment (gloves, eye protection, respirator if needed), spill containment, and fire extinguishing media (foam, CO₂, dry chemical). Personnel should be trained in flammable liquid handling.
Quality Preservation
White Spirit is a stable product with a shelf life of 24+ months under proper storage. Key preservation practices: prevent water ingress, minimize tank breathing (reduce moisture and oxygen exposure), avoid contamination with other products, maintain storage temperature within normal ambient range, and conduct periodic quality checks on stored inventory.
White Spirit vs Other Solvents
How White Spirit compares to related petroleum solvents in key performance and safety characteristics.
| Characteristic | White Spirit | Mineral Turpentine | Kerosene | Light Naphtha |
|---|---|---|---|---|
| Chemical Nature | Refined petroleum solvent — aliphatic + alicyclic hydrocarbons, C7–C12 | Essentially the same product — White Spirit and Mineral Turpentine are different names for refined hydrocarbon solvent | Middle distillate — heavier hydrocarbons C9–C16. Primarily a fuel, not a solvent. | Light petroleum fraction — C5–C6 hydrocarbons. Very volatile. Primarily petrochemical feedstock, not an industrial solvent. |
| Flash Point | 30–65°C (grade-dependent) | 30–65°C (same as White Spirit) | 38–72°C | < -20°C (highly flammable) |
| Evaporation Rate | Medium (0.10–0.15 vs n-BuAc = 1.0) | Medium (same as White Spirit) | Slow — heavier hydrocarbons evaporate slowly. Can leave oily residue. | Very fast — Light Naphtha evaporates too quickly for most industrial solvent applications. |
| Solvency (KB Value) | 28–40 (grade-dependent) | 28–40 (same as White Spirit) | 25–30 (weaker solvency than White Spirit) | 30–35 (moderate, but evaporation too fast for practical use in most solvent applications) |
| Primary Applications | Paints, coatings, industrial cleaning, printing inks, adhesives, construction chemicals | Same as White Spirit — paints, coatings, cleaning. Different name, same applications. | Heating fuel, jet fuel (Jet A-1), lighting, some cleaning. NOT a paint solvent. | Petrochemical feedstock (steam cracking for ethylene). NOT an industrial solvent — flash point is too low for safe solvent use. |
| Industrial Solvent Use | Primary industrial solvent — purpose-refined for solvent applications | Same as White Spirit — purpose-refined for solvent applications | Limited solvent use — primarily a fuel. Heavier, slower-evaporating, can leave residues. | Not suitable as industrial solvent — too volatile, too flammable. Used as petrochemical feedstock, not in solvent applications. |
White Spirit Quality Control
Comprehensive quality control ensures White Spirit consistently meets specification requirements and performs reliably in industrial applications.
Product Testing
White Spirit is tested using standardized ASTM methods at each stage of the supply chain: producer refinery, storage terminal, vessel loading, and vessel discharge. Key tests include distillation (ASTM D86), flash point (ASTM D93), density (ASTM D4052), aromatic content (ASTM D1319 or GC), sulfur (ASTM D5453), color (ASTM D156), and copper corrosion (ASTM D130).
Quality Verification
Independent inspection agencies — SGS, Intertek, Bureau Veritas, and Saybolt — perform cargo inspection and testing at load and discharge ports. The Certificate of Quality issued by the independent inspector is the definitive quality document for the cargo. Laboratory accreditation to ISO 17025 ensures testing competence and international recognition of results.
Specification Compliance
Each production batch and cargo is tested against the agreed specification. Parameter ranges (min–max), target values, and allowable tolerances are defined in commercial contracts. Out-of-specification results trigger investigation, re-sampling, and potentially commercial remedies — price adjustment, reprocessing, or cargo rejection depending on the parameter and deviation.
Batch Consistency
Industrial solvent users — particularly paint and coating manufacturers — depend on batch-to-batch consistency for stable product formulations. Consistent White Spirit quality (distillation range, aromatic content, evaporation rate) ensures consistent end-product performance. Suppliers maintain batch records for traceability and quality trending.

What Is White Spirit
White Spirit is a refined petroleum-derived hydrocarbon solvent consisting primarily of aliphatic (paraffinic) and alicyclic (naphthenic) hydrocarbons in the C7–C12 range. It is produced through the atmospheric distillation of selected crude oil fractions, followed by hydrodesulfurization to remove sulfur compounds and, for low aromatic grades, hydrode-aromatization to reduce aromatic hydrocarbon content.
White Spirit is a clear, water-white liquid with a characteristic mild hydrocarbon odor (very low in de-aromatized grades). It has a medium evaporation rate, moderate solvency for oils, resins, and polymers, and a flash point between 30°C and 65°C depending on grade. These properties make White Spirit one of the most widely used industrial solvents globally.
- ▸Chemical family: Petroleum hydrocarbon solvent
- ▸Carbon range: C7–C12 (predominantly)
- ▸Physical state: Clear, colorless liquid at ambient temperature
- ▸Classification: Flammable (Class IC) or combustible liquid depending on flash point
- ▸Production: Crude oil distillation + hydrotreating
- ▸Alternative names: Mineral Turpentine, Mineral Spirits, Stoddard Solvent
What Is Mineral Turpentine
Mineral Turpentine is an alternative name for White Spirit — the two terms refer to the same petroleum-derived hydrocarbon solvent. "Mineral Turpentine" is the preferred term in many industrial, manufacturing, and paint industry contexts, particularly in the UK, Commonwealth countries, and parts of Asia and Africa. "White Spirit" is the more common term in European and Middle Eastern markets.
It is important to distinguish Mineral Turpentine (a petroleum solvent) from Gum Turpentine — a natural solvent distilled from pine tree resin. Gum Turpentine has different chemical composition (primarily terpenes), stronger solvency, faster evaporation, and different odor. Mineral Turpentine replaced Gum Turpentine in most industrial applications due to consistent quality, stable supply, and lower cost.
What Is Stoddard Solvent
Stoddard Solvent is the historical and technical name for White Spirit, originating from the dry cleaning industry in the early 20th century. It was developed by W.J. Stoddard, a dry cleaner in Atlanta, Georgia, as a safer alternative to the more volatile and flammable petroleum solvents then in use.
The term "Stoddard Solvent" is still commonly used in technical literature, safety data sheets, and North American regulatory contexts. It is synonymous with White Spirit and Mineral Spirits, though some technical definitions restrict Stoddard Solvent to a narrower distillation range (149–204°C) with a minimum flash point of 38°C. In practice, the terms are used interchangeably in most commercial and industrial contexts.
White Spirit Industrial Applications
White Spirit is one of the most versatile industrial solvents with applications across paint manufacturing, coatings production, industrial cleaning, printing inks, adhesives, construction chemicals, and manufacturing operations. Its balanced combination of effective solvency, controlled medium evaporation rate, and favorable safety profile makes it the preferred solvent for countless industrial processes.

- ▸Industrial Coatings: Solvent carrier in protective coatings, marine paints, automotive refinish, and metal primers.
- ▸Industrial Cleaning & Degreasing: Removes machining oils, greases, waxes, and protective coatings from manufactured parts and equipment.
- ▸Printing Inks: Solvent in lithographic and letterpress inks — controls viscosity and drying rate for consistent print quality.
- ▸Adhesives & Sealants: Solvent in contact adhesives, rubber-based adhesives, and construction sealants.
- ▸Construction Chemicals: Solvent in concrete curing compounds, form release agents, waterproofing treatments.
White Spirit Safety Considerations
White Spirit safety considerations center on flammability, health effects from inhalation and skin contact, and environmental protection. The specific safety requirements vary by grade — Low Aromatic White Spirit has a better health and safety profile than Regular (higher aromatic) grades.
- ▸Flammability: Regular White Spirit (flash point 30–40°C) is a Class IC flammable liquid. High Flash White Spirit (≥ 55°C) is classified as combustible — significantly safer. Grounding, bonding, ventilation, and elimination of ignition sources are essential during handling.
- ▸Inhalation: White Spirit vapors can cause drowsiness, headache, and respiratory irritation at high concentrations. Use in well-ventilated areas. Respiratory protection may be required in confined spaces or where ventilation is inadequate.
- ▸Skin Contact: Prolonged or repeated skin contact can cause defatting and dermatitis. Impermeable gloves (nitrile, neoprene) and protective clothing are recommended for regular handling.
- ▸Environmental: White Spirit is toxic to aquatic life. Spills should be contained and prevented from entering drains, soil, or watercourses. Spent White Spirit should be disposed of as hazardous waste per local regulations.
White Spirit Transportation & Storage
White Spirit is transported internationally by chemical/product tankers in bulk, or in drums, IBCs, flexitanks, and ISO tank containers for smaller volumes. As a flammable/combustible liquid, White Spirit is subject to dangerous goods regulations (IMDG Code for marine, ADR for road, IATA for air).
- ▸Marine Transport: Chemical/product tankers (5,000–40,000 DWT) with coated cargo tanks. IMDG Class 3, Packing Group II (flash point < 23°C) or III (flash point 23–60°C). Cargo segregation and ventilation per IMDG requirements.
- ▸Bulk Storage: Fixed-roof carbon steel tanks with internal coating. Grounding, flame arrestors on vents, water drainage, and temperature monitoring. Tank cleaning between products prevents cross-contamination.
- ▸Packaged Storage: Steel drums (200L) or IBCs (1,000L) stored in well-ventilated, cool, dry areas away from ignition sources, direct sunlight, and incompatible materials. Stacking per local regulations.
- ▸Shelf Life: 24+ months under proper storage conditions. White Spirit is a stable product — quality degradation during storage primarily results from water ingress, contamination, or exposure to extreme temperatures.

What is the evaporation rate of White Spirit?
White Spirit has a medium evaporation rate of 0.10–0.15 relative to n-butyl acetate (n-BuAc = 1.0). This medium evaporation rate provides a good balance — fast enough for reasonable drying times in paints and coatings, slow enough for adequate working time and good film formation.
What is the density of White Spirit?
White Spirit density ranges from 0.750 to 0.820 g/cm³ at 15°C. Density varies with aromatic content — higher aromatic grades have higher density. Low aromatic grades typically range 0.750–0.780 g/cm³. White Spirit is lighter than water and will float on top of any water present in storage tanks.
Is White Spirit the same as Kerosene?
No. White Spirit and Kerosene are different petroleum products with different applications. White Spirit (C7–C12) is purpose-refined as an industrial solvent for paints, coatings, and cleaning. Kerosene (C9–C16) is a heavier middle distillate primarily used as heating fuel and jet fuel — it evaporates more slowly, has weaker solvency, and can leave an oily residue.
Is White Spirit the same as Naphtha?
No. White Spirit (C7–C12, flash point 30–65°C) is an industrial solvent. Light Naphtha (C5–C6, flash point < -20°C) is a highly volatile, highly flammable petrochemical feedstock — not suitable as an industrial solvent due to its extreme flammability and very fast evaporation. They are different petroleum fractions with different applications.
What is the KB Value of White Spirit?
The Kauri-Butanol (KB) value measures relative solvency power. White Spirit has a KB value of 28–40 depending on grade. Low Aromatic grades: 28–33 (moderate solvency). Regular grades: 35–40 (stronger solvency due to higher aromatic content). The KB value helps formulators select the appropriate grade for specific resin and coating systems.
Can White Spirit be used indoors?
Low Aromatic White Spirit is preferred for indoor applications due to very low odor and lower toxicity. Regular White Spirit (15–20% aromatics) has a stronger hydrocarbon odor and should only be used in well-ventilated indoor areas. Always follow the safety data sheet (SDS) recommendations for the specific product and ensure adequate ventilation.
