In 1907 the chemists at Henkel succeed in revolutionizing laundry. They combine sodium silicate with sodium perborate, which when boiling the laundry releases fine pearling oxygen. This not only has the effect of – in contrast to the chlorine used up to then – an especially textile-friendly and odourless bleach. It also takes away the strenuous and time-consuming rubbing, swinging and scrubbing of the laundry for the housewives. The first self-acting detergent is born: Persil. The first announcement advert appears on 6 June 1907 in the Düsseldorf newspaper. Then Persil makes its way into the retail trade packaged in thin cardboard cartons with printed paper wrapping made and filled by hand.
