摘要:
The invention relates to a method for reducing or preventing the decomposition of a composition Z, containing Z1 a salt of dithionous acid in an amount in the range of 50 to 100 wt% and possibly Z2 an additive selected from the group consisting of alkali metal carbonate, alkaline-earth metal carbonate, alkali metal or alkaline-earth metal tripolyphosphate (Na 5 P 3 O 10 ), alkali metal or alkaline-earth metal sulfite, disulfite, or sulfate, dextrose, and complexing agent in a total amount in the range of 0.0001 to 40 wt%, wherein the components Z1 and, if applicable, Z2 in a solid and/or dry state or in a state of suspension in a solvent are brought into contact with at least one of the following compounds V in a solid and/or dry state or in a state of suspension in a solvent, wherein the compounds V are selected from the group consisting of: (a) oxides of the alkali metals lithium, sodium, potassium, rubidium, cesium, or magnesium, (b) sodium tetrahydroborate (NaBH 4 ), (c) water-free copper(II) sulfate (Cu(SO 4 )), phosphorus pentoxide, and (d) basic amino acids arginine, lysine, histidine, characterized in that the solvent for Z1, Z2 if applicable, and V is practically free of water.
摘要:
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.
