Abstract (en)

[origin: WO9703166A1] The invention concerns colour transfer-inhibiting washing agents whose object is to optimize the washing process by minimizing colour transfer, maximizing colour shade maintenance and maximizing cleaning performance. This object is substantially achieved by lowering the content of non-ionic surfactant to amounts of at most 8 wt %. The agents can be used in processes for preventing changes in colour shades and for inhibiting colour transfer to white or differently-coloured laundry when washing coloured laundry, alone or combined with white laundry, in aqueous, surfactant-containing liquor.
