"Sonax Chemical characterization: Corrosion inhibitors in a hydrocarbon compound"
"WD-40 is the trademark name of a water-displacing spray widely available in a variety of retail outlets. Developed in 1953 by Norm Larsen, then working for the San Diego Rocket Company, it was originally designed to repel water and prevent corrosion. WD-40 is primarily composed of various hydrocarbons.
WD-40's main ingredients, according to U.S. Material Safety Data Sheet information, are:
50%: 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"
hmmmmm
