DOES WD-40 CONTAIN FISH OIL?
Hi Chef James,
I have been told that the main ingredient in WD40 lubricant and rust remover is fish oil! Is this true?
Thanks, John K.
Fish Oil is NOT an ingredient in WD-40. This is another urban legend that has been around for a long time.
WD-40's main ingredients, according to its U.S. Material Safety Data Sheet* information, are:
· 51% Stoddard solvent (i.e., mineral spirits: primarily hexane, somewhat similar to kerosene)
· 25% Liquefied petroleum gas (presumably as a propellant; carbon dioxide is now used instead to reduce WD-40's considerable flammability)
· 15+% Mineral oil (light lubricating oil)
· 10-% Inert ingredients
The German version of the mandatory EU safety sheet lists the following safety-relevant ingredients:
· 60–80% Heavy Naphtha (petroleum product), hydrogen treated
· 1–5% Carbon dioxide
It further lists flammability and effects to the human skin when repeatedly exposed to WD-40 as risks when using WD-40. Nitrile rubber gloves and safety glasses should be used.
* Required by the U.S. Occupational Safety and Health Administration (OSHA) for potentially hazardous substances in the workplace.
