WD-40 isn't kerosene, from Wikipedia entry: Formulation[edit]
WD-40's formula is a trade secret. To avoid disclosing its composition, the product was not patented in 1953, and the window of opportunity for patenting it has long since closed.[7] WD-40's main ingredients as supplied in aerosol cans, according to U.S. Material Safety Data Sheet information, are:

"50% "aliphatic hydrocarbons". The manufacturer's website claims this ratio in the current formulation cannot accurately be described as Stoddard solvent, a similar mixture of hydrocarbons.[13]
<25% petroleum base oil. Presumably a mineral oil or light lubricating oil.
12–18% low vapor pressure aliphatic hydrocarbon. Reduces the liquid's viscosity so that it can be used in aerosols. The hydrocarbon evaporates during application.
2–3% carbon dioxide. A propellant which is now used instead of the original liquefied petroleum gas to reduce WD-40's flammability.
<10% inert ingredients.
The German version of the mandatory EU safety sheet lists the following safety-relevant ingredients:

60–80% hydrogen-treated heavy naphtha (a petroleum product used in wick-type cigarette lighters)
1–5% carbon dioxide
It warns of the product's high flammability and the risk of irritation to human skin when repeatedly exposed to WD-40. Nitrile rubber gloves and safety glasses should be worn (ordinary rubber disintegrates if exposed to petroleum products). It also mentions that water is unsuitable for extinguishing burning WD-40.

In 2009, Wired published an article with the results of gas chromatography and mass spectroscopy tests on WD-40, claiming that its ingredients make it resistant to freezing."
