Abstract (en)
[origin: EP1892284A1] A bleaching agent solution (A) comprises imidoalkane-percarboxylic acid bleaching agent(s) (I) in a solvent system containing main solvent(s) (II) selected from: (a) glycol dialkanoate esters; (b) dialkyl dicarboxylate or trialkyl propane-tricarboxylate esters; (c) (ar)alkyl esters of formic, acetic or propionic acid (or derivatives); (d) alkyl or (ar)alkyl benzoates or dialkyl or di(ar)alkyl iso- or terephthalates; and/or (e) lactones. A bleaching agent solution (A) comprises at least one imidoalkane-percarboxylic acid bleaching agent (I) in a solvent system containing main solvent(s) (II) selected from: (a) di-(1-4C) alkylcarboxylic acid esters of ethylene glycol, 1,2- or 1,3-propylene glycol, 1,2-, 1,3-, 1,4- or 2,3-butylene glycol, 2-methyl-1,3-propylene glycol or 1,2-, 1,4-, 1,5- or 2,4-pentylene glycol; (b) di-(1-4C) alkyl esters of 4-6C dicarboxylic acids (optionally methyl-substituted in the beta - and/or gamma -position) or tri-(1-4C) alkyl esters of 1,2,3-propane-tricarboxylic acid; (c) aryl and/or aralkyl esters of formic, acetic and/or propionic acid (the acids optionally being substituted by aryl or aralkyl); (d) 1-4C alkyl, aryl or aralkyl benzoates or di-(1-4C) alkyl, diaryl or diaralkyl isophthalates or terephthalates; and/or (e) monohydroxy-carboxylic acid lactones. Independent claims are included for: (1) two-component liquid cleansing compositions, in which one component is (A); and (2) two-component cleaning compositions, in which one component is (A) and the other is a solid cleaning composition.
