The origins of the soap date back to the Babylonians around 2800 BC. It is also mentioned in the Egyptian papyri and in the Bible. Over the centuries, soap has been used to wash wool in the textile industry, to treat wounds and skin diseases, to dye hair and as an ointment. Soap comes from the Latin sapo, a word that is believed to be of Germanic origin, which came to Latin through the roosters. According to some scholars, the use among roosters would explain the fortune of the soap industry in France, particularly in Marseille. The soap is prepared by combining fats of animal origin lard, butchery waste or vegetable coconut oil, almond oil, sunflower oil, etc. with alkaline substances for example caustic soda, producing the reaction that precisely calls saponification.
