Soap is created by the magical reaction that happens when you mix lye and oil. The first soap was made hundreds of years ago when some oil spilt into the ashes of a cooking fire, creating a substance which people soon discovered would clean things.
All real soap starts with lye. If it doesn't have lye (or its scientific name, sodium hydroxide) on the label, or it doesnt say "saponified", it's not real soap, it's a synthetic detergent.
