When I read more than once people said WD40 is kerosene, I wanted to reply with what I "knew" about WD40 ingredients. I've "known" for years that the main ingredient of WD40 is fish oil. I swear I read that somewhere very official, it was the truth. But I felt I would be challenged on that so I needed to cite my source. Went to the WD40 website and they deny any fish oil is in it. They say it's a secret recipe nobody knows what is in it but definately not fish oil. Now I have to know what it is. The answer was only a google away. These guys analyzed it with a gas chromatograph; reverse engineered the "secret" recipe. No kerosene in it either.

WD40 MSDS:
Bulk liquid - https://wd40.com/files/pdf/msds-wd482671453.pdf
Aerosol - https://www.cla.purdue.edu/polsci/documents/safetydocs/msdadocs/wd40.pdf
Wiki article on kerosene - https://en.wikipedia.org/wiki/Kerosene
Per the MSDS, WD40 contains 45-50% "aliphatic hydrocarbons." The Wiki article states that kerosene is largely "alkanes" (and naphthenes, which are ring-shaped alkanes). For all you non-chemists, the terms "aliphatic hydrocarbon" and "alkane" are synonymous.
