Lighter fluids are consumer products used at a low volume scale, representing a realistic goal for fossil fuel replacement by renewables. Lighter fluids are liquid substances or mixtures that are readily ignitable by flame and can be used to ignite solid barbecue fuel, like charcoal. They are composed primarily of aliphatic hydrocarbons—chains of carbon and hydrogen atoms—that are typically 9 to 14 carbon atoms long (C9-C14). Lighter fluids are also known as naphtha, a volatile flammable liquid hydrocarbon mixture used in wick-type lighters and burners. The energy in fossil fuels comes from the sun, which drives photosynthesis to change carbon dioxide and water into the molecular building blocks of ancient plants and animals.

Lighter fluid is a refined fraction of petroleum
Lighter fluid, also known as naphtha, is a refined fraction of petroleum. It is a highly volatile liquid that evaporates quickly when exposed to air. Lighter fluid is composed primarily of aliphatic hydrocarbons, which are chains of carbon and hydrogen atoms. These hydrocarbons typically contain 9 to 14 carbon atoms (C9-C14). The raw distillate is processed to remove impurities such as sulfur, reducing air pollutants when burned. This results in a "hydrotreated" product.
Lighter fluid has a low flash point, typically around 40°C (104°F), which is the temperature at which it produces enough vapour to be ignited by a spark. This makes it highly flammable and easy to ignite, contributing to quick and efficient lighting. Its low viscosity allows it to soak into porous materials, such as charcoal briquettes, and its vapour density creates a concentrated cloud of fuel that can cause mini-explosions if ignited from above.
Lighter fluid is commonly used in traditional wick lighters and fluid-fueled lighters, as well as for lighting charcoal in barbecue grills. It is known for its reliability and ease of ignition, making it a popular choice among smokers and for outdoor grilling. One of the main advantages of lighter fluid is its affordability and wide availability.
However, there are concerns about the safety and environmental impact of lighter fluid. The vapours produced by lighter fluid can pose a severe acute risk if inhaled, as they can easily enter the lungs and cause chemical pneumonia. Additionally, the use of lighter fluid in grilling has been debated due to its potential toxicity and impact on food flavour. Efforts have been made to replace lighter fluid with biomass-based alternatives, but the volume of consumption remains a crucial factor in these endeavours.
In summary, lighter fluid is a refined fraction of petroleum that has been traditionally used for lighting purposes due to its ease of ignition and affordability. While it is widely available and reliable, there are safety and environmental concerns associated with its use, leading to a growing interest in sustainable alternatives.

Alternatives to fossil fuels in lighter fluid
Lighter fluids are consumer products used only at a low-volume scale, which means that replacing fossil fuels with renewable alternatives is a realistic goal. Several biomass-based chemicals have been identified as potential alternatives to fossil fuels in lighter fluids. These alternatives include:
- Γ-valerolactone
- Ethyl-levulinate
- Ethanol
- N-butanol
- Γ-valerolactone 90% v/v and ethanol 10% v/v
- Ethyl-levulinate 90% v/v and ethanol 10% v/v mixtures
These alternatives were assessed based on safety, toxicological, and environmental factors. For instance, flash point, boiling point, vapour pressure values, and evaporation rates were considered. Additionally, oral toxicity was measured using rats.
Another alternative to fossil fuels in lighter fluids is butane, a highly flammable, colourless, and easily liquefied gas used in gas-type lighters and torches. Butane burns to produce water vapour and CO, without any noxious chemicals or fumes. However, it is important to note that butane may not be suitable for all lighters, as some are designed to use liquid fuel.
Furthermore, VM&P Naphtha (Varnish Maker & Painter's Naphtha) has been suggested as an alternative to Zippo lighter fluid. It is slightly cheaper and produces fewer fumes while lasting longer.

Safety and toxicological concerns
Lighter fluids are consumer products that are used only at a low-volume scale, and they represent a realizable goal for the replacement of fossil fuels by renewable energy sources. Lighter fluids are liquid substances or mixtures that are readily ignitable and can be used to ignite solid barbecue fuel, such as charcoal. They are composed of volatile organic compounds (VOCs) and, when burned, release harmful chemicals into the air.
The safety and toxicological concerns associated with lighter fluids are significant and should be carefully considered. The harmful substances in lighter fluids are called hydrocarbons, and their inhalation can lead to respiratory problems and exacerbate existing health issues. Additionally, if the lighter fluid is not burned off completely, the residue can end up on food, introducing potentially harmful chemicals into the diet. The production and disposal of lighter fluid also contribute to environmental pollution.
Lighter fluid poisoning can occur when someone swallows this substance. If the lighter fluid is on the skin or in the eyes, it is important to flush the affected area with water for at least 15 minutes. If swallowed, give the person water or milk right away, if advised to do so by a medical professional. It is important to note that you should not give anything to drink if the person is experiencing symptoms such as vomiting, convulsions, or a decreased level of alertness. If the person has inhaled the fumes, move them to fresh air immediately and seek medical attention.
Butane, a common component of lighter fluids, has been studied for its acute exposure effects on animals. Case reports indicate that butane's effects on the brain (encephalopathy) or heart (cardiotoxicity or cardiac sensitization) might lead to death. Animal studies have shown that exposure to butane can cause "light anesthesia" and a "dazed appearance". High concentrations of butane can lead to drowsiness and even lethality.
The use of lighter fluid poses a particular risk to children, who may be drawn to the colourful containers or accidentally ingest the fluid if it is not stored properly. The open flames produced by lighter fluid also pose a burn hazard to children. Safer alternatives to lighter fluid are available, such as charcoal chimney starters, electric starters, or eco-friendly tumble weed starters, which are not only safer but also more environmentally friendly and cost-effective in the long run.

Environmental impact of fossil fuels in lighter fluid
Lighter fluids are consumer products used only at a low volume scale, presenting a realizable goal for the replacement of fossil fuels by renewables. Some examples of fossil-based conventional lighter fluids include Ronsonol, Zippo, Landmann, and Terracotta. These lighter fluids are liquid substances or mixtures that are readily ignitable by flame and can be used to ignite solid barbecue fuel, such as charcoal.
The environmental impact of fossil fuels in lighter fluids is a cause for concern. Despite the efforts of researchers, engineers, and politicians, our society remains heavily dependent on fossil resources. In 2021, 82.2% of the world's primary energy consumption was based on oil, natural gas, and coal. While it is not possible to completely avoid the use of fossil resources in the energy sector, there is a growing emphasis on replacing them with biomass-based alternatives. The chemical industry has been exploring biomass-based consumer products for two decades, and some of these suggestions have become industrially viable.
However, the volume of consumed chemicals is a crucial factor in the replacement of fossil fuels. Lighter fluids, for instance, are consumed at a kiloton scale, and any alternative must possess similar physicochemical properties as the fuels used in the energy sector. Assessments of potential biomass-based lighter fluids have been conducted in terms of safety, toxicological, and environmental considerations, including flash point, boiling point, vapor pressure values, and evaporation rates.
The environmental impact of fossil fuels in lighter fluids is significant, and the search for sustainable alternatives is an active area of research. The goal is to replace fossil-based lighter fluids with chemicals derived from biomass conversion, reducing our reliance on finite fossil resources and mitigating their environmental footprint.
