Soap bars are the most traditional and proven method of personal cleansing.
The first known soap bar was a mixture of boiled fats and ashes, and actually used for hair styling in Ancient Babylon (around 2800 B.C.).
Around 1500 B.C., the Egyptians mixed animal and vegetable oils with alkaline salts to treat skin diseases and for washing their skin.
By the 17th century, soap-making in Europe had become an established craft. The main producers were Italy, Spain and France; countries which also produced the raw materials for soap bars, such as olive oil. At this time, soaps were produced by mixing vegetable and animal oils, plants and fragrances.
By the 19th century, modern soap production techniques had developed and soaps could be produced in large scale, ushering in soap production as we know it today
