In the early beginnings of soap making, it was an exclusive technique used by small groups of soap makers. The demand for soap was high, but it was very expensive and there was a monopoly on soap production in many areas. Over time, recipes for soap making became more widely known, but soap was still expensive. Back then, plant byproducts and animal and vegetable oils were the main ingredients of soap. The price of soap was significantly reduced in 1791 when a Frenchman by the name of LeBlanc discovered a chemical process that allowed soap to be sold for significantly less money.
