In 1907, Henkel's chemists succeeded in revolutionizing washing. They combined sodium silicate with sodium perborate, which released fine, sparkling oxygen when the laundry was cooked. Unlike the chlorine used until then, this not only produces a bleach that is particularly gentle on textiles and odorless, but also makes the laundry more comfortable to use. It also relieves housewives of the tiring and time-consuming rubbing, swiveling and milling of the laundry. The first self-acting detergent is born: Persil. On June 6, 1907, the first advertisement appears in the Düsseldorfer Zeitung. Persil was then sold in hand-made and filled packages made of straw cardboard with a printed wrapper.
