As you know, soap bars and soap are welcome and useful in our daily lives, let's talk about the history of soap today. Well, humans have used soap for millennia. It has a long history, Evidence has been found that ancient Babylonians understood soap making as early as 2800 BC Archeologists have found soap-like material in historic clay cylinders from this time. These cylinders were inscribed with what we understand as saying, “fats boiled with ashes” (a method of making soap). According the record, we may surmise that soap was invented in 2800 BC, such an ancient time.
