(FR) COMPOSITION DE BLANCHIMENT DETERGENTE
Abstract
(EN)
In a fabric washing process, the resulting colour-fading of coloured fabric (particularly coloured cotton fabric) is reduced while maintaining a favourable bleaching performance by using a detergent bleach composition comprising a surface-active material, a peroxy bleaching agent and a specific type of a dinuclear manganese complex as effective bleach catalyst. A particularly preferred dinuclear manganese complex is: [(Et-bridged(Me2TACN)2)MnIIIMnIV($g(m)-0)2($g(m)-OAc)]2+(PF6-)2.
(FR)
Dans un processus de lavage de tissus, on réduit la décoloration résultante des tissus colorés (en particulier des tissus en coton de couleur) tout en conservant une efficacité de blanchiment avantageuse en utilisant une composition de blanchiment détergente comprenant un agent tensioactif, un agent de blanchiment au peroxyde et un type spécifique de complexe au manganèse dinucléaire en tant que catalyseur de blanchiment. Le complexe au manganèse dinucléaire particulièrement préféré est: [(Et-(Me2TACN)2ponté)MnIIIMNIV($g(m)-0)2($g(m)-OAc)]2+(PF6-)2.
