https://yarchive.net/chem/wd40.html "That would make WD-40 like the formulation above.
The kerosine is the solvent, the tallow oil and lubricating
base grade provide the means for the fluid to displace
water from surfaces and, when the kerosine has evaporated,
leave a thin, protective film on the surface that provides
temporary corrision protection. It is possible that it may
have some solid lubricant in it ( PTFE,Graphite,MoS2 ),
but I suspect there would not be enough to provide any
useful lubrication - and thus should not be used to wash
"proper lubricants" off bearing surfaces, chains etc..
