Abstract (en)

[origin: WO2007107308A2] The invention relates to agents which are contained in a carrier of a combination of special sulphinic acid derivatives of formula (I), wherein M represents a hydrogen atom or an equivalent of a mono or polyvalent cation, R is derived from a peptide or represents a group according to one of the formulae (II) to (VI), (for the meanings of the remaining substitutients see claim 1) and contains at least one non-ionic surfactant. Said agents enable a durable decolouration of the dyed substrates to take place without darkening the decoloured substrate. The substrate structure is not damaged during the decolouration process.
