Metal free bleaching composition

A process for the bleaching of stains or of soiling on textile materials or dishes in the context of a washing process or by the direct application of a stain remover comprising

• treating a textile material or dishes in an aqueous medium either by hand or in an automatic washing machine or dishwasher, at a pH between 7 and 11, together with a mixture comprising
• a) H2O2, a precursor of H2O2, or a peracid and
• b) a compound of formula (3)
• wherein
• R′1 is SCH3, S(O2)CH3, H, CH3, S(O)CH3, (CH3)2S+BF4− or (CH3)2S+(CH3O)S(O2)O−;
• or a compound of formula (4)
• wherein
• R′1 is H, CH3, SCH3, S(O)CH3 , S(O2)CH3, (CH3)2S+BF4− or (CH3)2S+(CH3O)S(O2)O−;
• or a compound of formula (5)
• wherein
• R′1 is SCH3, S(O2)CH3, H, CH3, S(O)CH3, (CH3)2S+BF4− or (CH3)2S+(CH3O)S(O2)O−;
• or a compound of formula (6)
• wherein
• R′1 =SCH3, S(O)CH3, S(O2)CH3, (CH3)2S+BF4− or (CH3)2S+(CH3O)S(O2)O−;
• or
• a compound of formula (7)
• wherein
• R′1 =H, S(O)CH3, S(O2)CH3, (CH3)(CH3CH2)S+BF4−, (CH3)2S+BF4−, (CH3)2S+PF6− or (CH3)2S+(CH3O)S(O2)O−;
• wherein the mixture is free of metal complexes, and
• wherein component a) is present in an amount of from 2 parts to 90 parts by weight and component b) is present in an amount of from 0.02 parts to 20 parts by weight;
• the sum being 100 parts.
