                                   Kerosene

Kerosene oil is a flammable liquid which is used in many industries and homes around the world as a fuel for light, heat and power. It is generally non-viscous and clear, however viscous substances such as wax and other thicker substances can be made from kerosene.

The chemical composition of kerosene is fairly complex, and it is a complex mixture of paraffins (55.2%), naphthene's (40.9%), and aromatic hydrocarbons (3.9%). Kerosene tends to contain hydrocarbons that have anywhere from 11 to 13 carbons in the chains. Liquid kerosene fuels contain potentially harmful compounds, including hexane and benzene.

Kerosene is widely used to power jet engines of aircraft (jet fuel), as well as some rocket engines in a highly refined form called RP-1. It is also commonly used as a cooking and lighting fuel, and for fire toys such as poi. In parts of Asia, kerosene is sometimes used as fuel for small outboard motors or even motorcycles.

In developing countries, the widespread use of kerosene comes with numerous different issues. Hazards of kerosene use include poisoning, fires, and explosions. As well, some kerosene lamps emit fine particulates, carbon monoxide, nitric oxides (NOx), and sulfur dioxide when burned. These by-products may reduce lung function and increase risks of asthma and cancer. Taking into account the risks of using kerosene, cleaner alternatives to kerosene technologies for lighting and cooking should be investigated - although kerosene is still a safer option in many cases than using solid fuels.
