The Birth of WD-40

The birth of WD-40 is a story that begins in the early 1950s, in the laboratories of a small, fledgling company in San Diego, California. The company, originally named the Rocket Chemical Company, was founded by a small group of chemists led by a man named Norm Larsen.

In 1953, Norm Larsen and his team were on a mission to create a rust-prevention solvent and degreaser that could be used in the aerospace industry. The “WD” in WD-40 stands for “Water Displacement,” and the “40” refers to the number of attempts it took to get the formula just right. It was on the 40th try that they finally achieved the perfect combination of ingredients.

The original formula they developed was a petroleum-based concoction that not only displaced water effectively but also had remarkable lubricating properties. This dual-purpose formula turned out to be a game-changer, as it could be used for a wide range of applications beyond aerospace, from preventing corrosion on missiles to loosening stubborn nuts and bolts.

In 1958, the product was first sold to the public in aerosol cans under the name WD-40. It didn’t take long for people to discover its incredible versatility, and WD-40 became a household name in no time. Over the years, the product has undergone minor refinements, but its core formula has remained largely unchanged.

Today, WD-40 is not just a product; it’s an iconic brand known worldwide for its ability to solve countless everyday problems. It’s a testament to the ingenuity and perseverance of its creators, who, through trial and error, gave birth to a product that has become an indispensable tool for millions of people around the globe.

The exact formula of WD-40 is a closely guarded trade secret, so the specific ingredients and their proportions are not disclosed on the product’s label. However, WD-40 has historically been known to primarily contain the following general types of ingredients:

  • Petroleum-Based Lubricant: This is the main ingredient and forms the base of WD-40. It is typically composed of various hydrocarbons derived from crude oil. This lubricant provides the product’s primary function of reducing friction and providing a protective coating on surfaces.
  • Solvents: WD-40 contains one or more solvents to help dissolve and displace moisture, rust, and other contaminants. These solvents make it effective at loosening rusted or stuck parts.
  • Propellant: In aerosol cans, WD-40 uses a propellant to release the product in a spray form. Common propellants include propane and butane.
  • Fragrance: A small amount of fragrance is often added to mask the petroleum odor of the product, giving it a more pleasant scent.
  • Surfactants: These are surface-active agents that help in the emulsification of oils and water, making it easier to penetrate and clean surfaces.
  • Corrosion Inhibitors: Some formulations of WD-40 include corrosion inhibitors to provide additional protection against rust and corrosion.
  • Other Additives: WD-40 may contain various other additives to enhance its performance for specific applications, such as anti-wear additives for improved lubrication.

It’s important to note that WD-40 is designed to be a multi-purpose product, so its exact formulation can vary based on its intended use and regional regulations. The specific combination of these ingredients and their proportions may differ among different formulations and product variations within the WD-40 brand. If you have specific concerns about the ingredients in WD-40 or any allergies or sensitivities, it’s advisable to check the product label or contact the manufacturer for more information.
