Lubricant WD-40 - what kind of legends and tales do not go about it. And she allegedly improves the biting of fish, and protects her hands from sunburn, and almost does not give the dead a second life. However, today we will not talk about all sorts of prejudices and myths, but about the name of this miracle composition. Let's figure out why the grease has an index of 40 and what the letters WD mean.
Initially, WD-40 grease was created by the Americans for the needs of the defense sector (missile forces). The aerosol composition was developed in 1953 by chemist Norman Larsen for the Rocket Chemical Company, which is part of the overseas military-industrial complex. For the first time, the composition was used to protect commercial and military-carrier missiles of the Atlas family. Lubricant appeared on the civilian market just five years after its release - in 1958.
The abbreviation WD stands for "Water Displacement" or "Water Displacement". This is because the first and, in fact, the main purpose of the aerosol was to protect metal surfaces from corrosion. As for the index 40, there is no definitively reliable information on this matter. Norman Larsen himself always claimed that the number 40 simply means that the final version of the aerosol was created on the basis of 40th formula lubricants, 40th attempt at an aerosol formulation. If so, then it turned out extremely well.

Separately, the composition of the WD-40 lubricant should be noted. For a long time, the belief that Norman Larsen's creation was a secret dominated. This is not true. Moreover, today there are at least three formulas for the Water Displacement aerosol composition: Australian, European and American. As for the American composition, you can find 10% inert ingredients, 15% mineral oil, 25% carbon dioxide, 50% white spirit solvent in it. The fish oil content of WD-40 is a legend. The composition is flammable, cannot be effectively extinguished with water, and also poses a health hazard with prolonged exposure to human skin.
