The science of soap is more complex than one might imagine, requiring at least a rudimentary knowledge of chemistry. Even the most basic ingredients of soap rely on key reactions with other ingredients - a give and take that makes you wonder that we ever figured out how to make soap in the first place. It makes some sense then, that the creation of cleansing products was supposedly discovered by accident.










Vinegar
First there was wine, beloved by the ancients. Then there was wine gone bad - a mishap of leaky casks or stashes gone past their prime that mutated into one of the most versatile products in the world. “Vin aigre” (which roughly translates to “sour wine”) is a combination of acetic acid (aka ethanoic acid) - an organic compound which is the result of the miracle of fermentation - chemical reactions activated by the slow decay of everything from grapes to beets, malts to grains.
