Abstract (en)
[origin: WO2007107309A2] 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 has a sulphite ion content up to a maximum of 1,5 wt%. Said agents enable an improved decolouration of the dyed substrates to take place without darkening the decoloured substrate. The substrate structure is not damaged during the decolouration process.
