W5 Gallseife (Bile Soap)

W5 Gallseife is a traditional laundry stain remover sold primarily under the Lidl private label brand. The product utilizes natural bile soap enzymes to target tough organic stains like fat, blood, and ink. It is a staple in the DACH region (Germany, Austria, Switzerland) for eco-conscious yet effective cleaning.

The brand W5 is a proprietary brand of the German retail giant Lidl. Unlike independent brands, W5 products are manufactured by various contract manufacturers across Europe to meet Lidl's quality standards. The ownership remains entirely within the Schwarz Group, which manages the global operations of Lidl and Kaufland.
