For our ancestors it was natural to use alkaline substances for personal hygiene. But also other great cultures, like the Egyptians, have left evidence of the use of these substances for body care. The Egyptians, for example, used to take soothing, rejuvenating baths in Lake Natron, a lake full of sodium carbonate hydrate, also known as natron.
Even in our great-grandmothers’ times cleaning was mainly alkaline. Soft soaps with a high pH value, and quark wraps were considered excellent, well-proven alkaline remedies for gentle skin care. Special alkaline cosmetics were therefore considered unnecessary.
The history of acidic cosmetics begins in the 1950s. At the time, the cosmetic industry progressively switched towards the production of acidic cosmetics, given that the newly developed chemical surfactants had simplified the manufacturing, in an acidic environment, of formulations which then affirmed themselves as a substitute for soap.
