Testing Robustness and Compatibility of Colour Damaging Washing Tests

Part I: Colour Damage Profiles of Bleach Activators and Peroxycarboxylic Acids

Überprüfung der Aussagekraft und Kompatibilität von Farbschädigungstests
Teil I: Farbschädigungsprofile von Bleichaktivatoren und Persäuren
  • G. Reinhardt and H. Ulshöfer


A significant aspect when selecting new bleaching agents is their reactivity on dyed textiles. In this paper the colour damaging effect of various the bleach activators are compared with that of tetraacetyl ethylene diamine. The tests were carried out according to ISO 105-C09 (diagnostic single wash test) and a similar test as well as the recently developed colour damaging profile test (20 wash cycles) using the AISE Dye Set. The results confirm that new bleach systems can differ significantly in their reactivity and selectivity towards individual dyeings from the conventional peroxycarboxylic acids or peroxycarboxylic acid generating activators. ISO 105-C09 appears to be suitable for prediction of the effect of conventional peroxycarboxylic acids but shows deficiency in the assessment of new bleach systems such as perimidic acids.


Ein wesentlicher Aspekt bei der Selektion neuer Bleichmittel ist ihre Reaktivität gegenüber gefärbten Geweben. In dieser Arbeit wird die farbschädigende Wirkung verschiedener Bleichaktivatoren mit der des Tetraacetylethylendiamins verglichen. Die Versuche wurden sowohl gemäß oder in Anlehnung an ISO 105-C09 (diagnostic single wash test) als auch nach dem kürzlich entwickelten CDP Tests (20fach Wäsche) unter Verwendung des AISE Dye Sets durchgeführt. Die Ergebnisse belegen, dass sich neue Bleichsysteme in Reaktivität und Selektivität gegenüber einzelnen Färbungen von herkömmlichen Peroxycarbonsäuren bzw. peroxycarbonsäuren-generierende Aktivatoren signifikant unterscheiden können. ISO 105-C09 scheint geeignet, die Wirkung herkömmlicher Peroxycarbonsäuren vorherzusagen, zeigt aber Defizite bei der Beurteilung neuer Bleichsysteme, wie z.B. Perimidsäuren.

Dr. Gerd Reinhardt, born in Germany in 1953, received a Ph.D. in Organic Chemistry from the University of Cologne in 1982. In 1984 he joined the Surfactants and Auxiliaries Division of Hoechst AG (since 1997 part of Clariant GmbH) in Frankfurt, Germany. In his current position as R&D Manager, Dr. Reinhardt is responsible for Clariant's bleach development group.

Hermann Ulshöfer, born in Germany in 1943, obtained his engineer degree in textile chemistry in 1965 at the Research Institute for Textile Technology at Hohenstein. After that he started by working on a research program on lipid chemistry at the University of Minnesota. In 1967 he joined the Textile Dyestuff Department of Sandoz Ltd (since 1995 Clariant (Switzerland) Ltd). Until his retirement end of 2003 he was manager of the screening and fastness testing group. Since 2004 he works as consultant.
