WD- 40 is a common product that every household typically has on hand due to its useful purpose of preventing your door from expressing its discomfort, also known as that high-pitched squeak that nobody enjoys hearing to. WD-40 is composed of 3 main substances. This includes decane (C10H22) which is also a common ingredient of gasoline (it helps WD-40 remain a liquid at cold temperatures), dimethyl naphthalene (C12H12) which comes in 10 forms aka isomers, and carbon dioxide (CO2). “Decane can be extracted from various petroleum solvents, such as Stoddard solvent, via fractional distillation” (Sciencemaddness Discussion Board, 2016), (fractional distillation - separation of a liquid mixture into fractions differing in boiling point), which is also very toxic if consumed and should always be stored in tightly-closed bottles away from heat. Dimethyl naphthalene, not only is it the next main ingredient used in WD-40, but it is also used as a plant growth regulator (it naturally occurs in potatoes to promote sprouts). Dimethyl naphthalene is found in crude oil and coal tar.
