What Is Kerosene? Uses, Specifications Grades and Bulk Supply
Kerosene is a combustible hydrocarbon liquid obtained from the middle distillate fraction of crude oil. It is typically composed of a mixture of paraffins, cycloalkanes and a smaller amount of aromatic hydrocarbons, usually in the C9 to C16 carbon range. Because of its relatively stable combustion, higher flash point than gasoline and suitability for further refining, kerosene is widely used in aviation fuel, heating, lamps, industrial solvents, degreasing applications and several petroleum-based processes.
This guide explains what kerosene is, its chemical composition, key physical properties, common applications, ASTM grades such as 1-K and 2-K, aviation-related grades such as Jet A and Jet A-1, safety considerations, storage guidelines and important factors to check before bulk procurement.
What Is Kerosene?
Kerosene is a refined petroleum product produced through fractional distillation of crude oil. It is less volatile than gasoline but generally lighter than diesel fuel. It is usually clear to pale yellow, has a characteristic petroleum odor and does not dissolve in water. Depending on the grade and refining process, kerosene can be used as a heating fuel, lamp fuel, industrial solvent or as a base component for aviation turbine fuels.
Kerosene is also known as paraffin in some countries, lamp oil in certain consumer applications and aviation kerosene when used as a base for jet fuel. However, these terms can vary by market, so the technical specification should always be checked before purchase or use.
What Is the Chemical Formula of Kerosene?
Kerosene does not have a single chemical formula because it is not a pure chemical compound; it is a mixture of petroleum hydrocarbons, typically in the C9 to C16 carbon range. Its main components include alkanes, cycloalkanes and small amounts of aromatic hydrocarbons.
Fuel Comparison: Kerosene, Gasoline, and Diesel
Understanding the physical properties of these fuels is essential for industrial safety and efficiency.
| Feature | Kerosene | Gasoline (Petrol) | Diesel |
|---|---|---|---|
| Distillation Fraction | Light Mid-distillate | Light Fraction | Heavy Mid-distillate |
| Volatility | Moderate | Very High | Low |
| Storage Safety | Safer than Gasoline | Lower | Relatively High |
| Flash Point | Higher than Gasoline | Very Low | Usually High |
| Main Application | Jet fuel, Heating, Solvent | Gasoline Engines | Diesel Engines |
| Cold Performance | Better than Diesel | Good but highly volatile | Risk of gelling/freezing |
| Suitable for Vehicles? | Generally No | Only Gasoline Engines | Only Diesel Engines |
Although kerosene and diesel both belong to the middle‑distillate fraction of crude oil, they are not the same fuel and are used for different purposes.
Comparison of kerosene and gasoline: Gasoline is highly volatile and flammable at room temperature, making it dangerous for jet engines. Kerosene’s higher flash point makes it significantly safer.
Comparison of kerosene and diesel: While both provide high energy, kerosene has a much lower freezing point, which is why it is preferred for high-altitude aviation where temperatures drop drastically.

Main Uses of Kerosene
Kerosene is widely used in different industries due to its stable combustion characteristics, moderate volatility and suitable energy content. The most common applications include the following:
Jet Fuel
One of the most important uses of kerosene is as the base component of aviation turbine fuels such as Jet A and Jet A‑1. These fuels are refined kerosene fractions designed to provide stable combustion and reliable performance in aircraft turbine engines.
Heating Fuel
Kerosene is commonly used as a heating fuel in portable heaters, household heating systems and small industrial heating units. Its relatively stable burning characteristics make it suitable for controlled heat generation.
Lamp Fuel
Traditionally, kerosene has been used as a fuel for oil lamps and lighting devices. Because it produces a steady flame and relatively low smoke compared to heavier fuels, it has been widely used for lighting in rural areas and emergency situations.
Industrial Solvent
In several industries, kerosene functions as an industrial solvent or cleaning agent. It is often used to dissolve grease, oils and certain organic residues from mechanical parts, metal surfaces and industrial equipment.
Mining and Industrial Applications
Kerosene is also used in certain mining and mineral processing operations as a solvent, carrier liquid or auxiliary chemical in separation and extraction processes.
Is Kerosene Toxic?
Kerosene is a petroleum‑derived fuel and a hydrocarbon solvent. Although it is widely used as a fuel and industrial liquid, improper exposure may pose health risks. Following basic safety guidelines is important when handling kerosene.
Skin Contact
Prolonged skin contact with kerosene may cause skin irritation, dryness or dermatitis. Protective gloves are recommended, and exposed skin should be washed with soap and water after contact.
Inhalation of Vapors
Breathing kerosene vapors in poorly ventilated areas may lead to headaches, dizziness, nausea and respiratory irritation. Kerosene should always be used or stored in well‑ventilated environments.
Ingestion
Kerosene is toxic if swallowed and may cause serious damage to the digestive system. In some cases, aspiration into the lungs can result in severe respiratory complications and requires immediate medical attention.
The Production Process: From Crude to Clear Fuel
Kerosene is produced via fractional distillation. It sits between LPG (the lightest) and Bitumen (the heaviest). During refining, Sulfur is removed to meet environmental standards, and The resulting kerosene fraction may be further treated to meet fuel, solvent, heating or aviation-grade specifications.

The article explained different types of kerosene based on applications and various standards (like 1-K, 2-K, jet fuel, etc.). If I intend to use kerosene for domestic purposes like heaters or lamps (especially in rural areas or emergencies), or for a specific industrial application requiring a solvent with particular characteristics, how can I ensure I choose the correct type of kerosene that is both safe and effective? Are there specific indications on the packaging or product certificate I should look for?
Your question is critically important, as selecting the correct type of kerosene for specific applications affects both safety and the efficiency and longevity of your equipment. Based on the information in the article, to ensure you choose the right kerosene, you should pay attention to the following:
For Domestic Use (Heaters, Lamps, Stoves):
1-K Grade (ASTM D3699): The article clearly states that Kerosene Grade 1-K is preferred for use in household heaters and stoves due to its much lower sulfur content (less than 0.04 percent by weight). This ensures cleaner combustion, producing less smoke and odor. This is vital for the health of occupants and for equipment maintenance.
BS 2869 Class C1 Standard: In regions adhering to British standards, “Class C1” (or “Premium Kerosene”) is used for flueless heaters and lamps, similar to 1-K, emphasizing clean combustion.
Important Note: Strictly avoid using Grade 2-K for indoor use without proper ventilation, as its higher sulfur content (0.3 percent by weight) can lead to more pollutants and respiratory issues.
For Industrial Applications (as a Solvent):
Solvent Grades: The article mentions that some kerosene grades are used as solvents for cleaning, degreasing, and paint thinning, such as “Solvent 402” or “white spirit.”
Required Physical and Chemical Properties: In these cases, you should look for specific physical and chemical properties such as boiling point range, flash point, and miscibility with other substances. For instance, if you need a solvent with a high flash point, you should seek grades that possess this characteristic.
Specialized Odorless Grades: In certain sensitive industries (like food or pharmaceuticals) or where kerosene odor is undesirable, specialized “Odorless Kerosene” grades are used.
How to Ensure Correct Selection:
Packaging and Labeling: Reputable manufacturers typically indicate the kerosene standard or grade on the packaging or product label (e.g., “Kerosene 1-K” or “EN 590”).
Certificate of Analysis (COA): For bulk purchases or sensitive industrial applications, always request a Certificate of Analysis (COA) from the supplier. This certificate includes all precise technical specifications, such as sulfur content, flash point, freezing point, etc., which will help you verify that the product meets your requirements.
Consult the Supplier: If in doubt, consult a reputable product supplier and explain your exact application so they can recommend the most suitable grade.
By following these guidelines, you can ensure that your chosen kerosene is both safe and provides the highest efficiency for your intended application.
How do changes in “seasonal demand” (such as increased consumption for heating in winter) and “geopolitical events” (like conflicts or oil sanctions) impact the supply and pricing of kerosene in international markets? And how can kerosene suppliers and traders manage these fluctuations and ensure supply stability under various conditions?
Changes in seasonal demand and geopolitical events are two highly significant and influential factors affecting the supply and pricing of kerosene in international markets. Kerosene suppliers and traders must continuously monitor and analyze these factors to maintain supply stability and optimize pricing.
Impact of Seasonal Demand on Kerosene Supply and Pricing:
Increased Demand in Cold Seasons:
Heating Applications: In winter (especially in the Northern Hemisphere), demand for kerosene as heating fuel (in stoves and furnaces) increases sharply. This surge in demand typically leads to price increases.
Refinery Production Mix Adjustment: Refineries may increase kerosene production to meet this demand, reducing the output of other products (e.g., gasoline in winter). This shift in production mix can also impact the supply and pricing of other petroleum products.
Stable Jet Fuel Demand:
Unlike heating consumption, demand for jet fuel (a type of kerosene) is not primarily influenced by specific seasons and is more dependent on air travel volume and global economic growth. However, peak summer travel and holiday seasons can create minor fluctuations in jet fuel demand.
Managing Seasonal Fluctuations: Traders typically manage pricing and ensure supply stability by stockpiling (warehousing) during low-demand seasons and releasing it during peak seasons. Additionally, utilizing futures contracts can help hedge against seasonal price volatility.
Impact of Geopolitical Events on Kerosene Supply and Pricing:
Supply Disruptions:
Conflicts and Unrest: Wars, regional conflicts, or political instability in oil-producing regions (like the Middle East) can directly disrupt crude oil production, transportation, and refining. Such disruptions affect the kerosene supply chain, leading to reduced supply and sharp price increases.
Sanctions: Imposing sanctions against oil or petroleum product-producing countries can limit global supply and directly impact kerosene prices.
Shifting Trade Routes:
Geopolitical events can lead to changes in shipping routes (e.g., restrictions in strategic straits), which increase transportation costs and ultimately result in higher final kerosene prices.
Psychological Market Impact:
Even the threat of geopolitical events can lead to increased speculation and price hikes in global markets due to fear of supply shortages or increased precautionary demand.
Managing Geopolitical Events: To counter these risks, suppliers and traders employ strategies such as diversifying supply sources (avoiding reliance on a single region or country), establishing strategic reserves, and hedging through financial instruments (like forwards and options). Continuous analysis of global political and economic information is also crucial for anticipating and reacting quickly to these events.
The article mentions the historical significance of Kerosene for lighting before electricity. Why was Kerosene considered superior to the previous lighting oils? Was it the burn quality or the cost resulting from the new distillation methods?
Both factors were crucial, but burn quality was the key differentiator. The new fractional distillation methods (refined by Razi and later industrialized) produced a much purer, cleaner-burning fuel than animal fats or earlier oils. This resulted in less soot, brighter light, and a less objectionable odor, making it a superior and safer choice, which was then made widely affordable.
I could not refrain from commenting. Well written!
“We truly appreciate your feedback! It’s great to know the information was valuable to you. Thank you for taking the time to share your thoughts.”
Why isn’t aviation gasoline (Avgas) used in jet aircraft, and why is kerosene-based fuel (Jet A-1) mandatory?
There are two main reasons: safety and energy density. Kerosene has a higher flash point than gasoline, making it less likely to ignite accidentally during a leak or minor incident. Additionally, jet engines require fuel with high energy density for long-range efficiency, where kerosene outperforms gasoline.
A great technical overview. As of 2026, the aviation industry is rapidly transitioning towards SAF (Sustainable Aviation Fuel). How does the traditional Jet A-1 compare to these new bio-kerosenes in terms of Energy Density and “Drop-in” compatibility? Can your supply chain handle blended Jet A-1 that meets the new 2026 carbon-reduction mandates?
Hello Dr. Rossi! That is the defining question of our decade. Traditional Jet A-1 has an energy density of approximately $43.1 \text{ MJ/kg}$. Current SAFs are designed to be “Drop-in,” meaning they mimic this density and the chemical footprint of kerosene almost perfectly. At Universal Trades, we are already adapting our logistics to supply SAF blends that comply with international sustainability standards, ensuring that our partners in the aviation sector can meet their net-zero targets without modifying their existing aircraft engines.
