FIELD: chemistry.SUBSTANCE: invention relates to use of a composition containing HO, a HOprecursor or a peroxy acid, and a compound of formulafor bleaching stains or dirt on textile materials during a cleaning process or by direct application of a stain remover at pH of 7 to 11. In formulae (1) and (2) Xis an anion of an organic or inorganic acid selected from BF?, PF?, RSO?, RSO?, SO?, or Cl, where R is C-Calkyl; Ris hydrogen, phenyl-(SO)-, a straight C-C-alkyl, C-C-alkoxy group, C-C-alkylthio group, C-C-alkyl-S(O)-, C-C-alkyl-SO-, where the C-C-alkyl is unsubstituted or substituted with (CO)OR; or Ris S(R)(R)X'; Rand Rindependently denote a straight C-C-alkyl; X'has one of the values defined for X, and is the same or different; or Ris N(R)(R)(R)X"; R, Rand Rindependently denote a straight C-C-alkyl; X"has one of the values defined for Xand X', and is the same or different; R'has one of the values defined for R; Rand Rindependently denote hydrogen or a straight C-C-alkyl; or Rand Rtogether with the atom with which they are bonded form a cyclopentyl or cyclohexyl group; Rand Rindependently denote hydrogen, a straight or branched C-C-alkyl or C-C-alkyl, which is divided by one O atom; or Rand Rtogether with a nitrogen atom with which they are bonded form a pyrrolidine, piperidine or morpholine group or hexamethylene imine; Ris hydrogen or a straight or branched C-C-alkyl, under the condition that if in formulae (1) and (2) R, R', Rand Rdenote hydrogen, then Rand Rdo not denote an unsubstituted C-C-alkyl.EFFECT: improved bleaching procedure, effective bleaching at high pH values without harmful effect on fibres and textile materials.9 cl, 11 tbl |
