Patent

CA 2399852

A bleaching composition for laundry fabrics is provided, comprising: a bleach catalyst comprising a ligand which forms a complex with a transition metal, the complex catalysing bleaching of stains in the absence of peroxygen bleach or a peroxy-based or -generating bleach system; a dye transfer inhibition agent, and wherein the composition is substantially devoid of peroxygen bleach or a peroxy-based or -generating bleach system. The bleaching composition provides effective bleaching performance on fabric stains without unacceptable transfer of dyes between fabrics.

L'invention concerne une composition de blanchiment pour tissus lavable, comprenant: un activateur de blanchiment qui contient un liant formant un complexe avec un métal de transition, lequel complexe active le blanchiment des tâches en l'absence d'un agent de blanchiment peroxygèné ou d'un système de blanchiment à base de peroxygène ou produisant du peroxygène; et un agent empêchant le transfert de couleurs. Cette composition est sensiblement dépourvue de système de blanchiment produisant du peroxygène ou à base de peroxygène. La composition de blanchiment offre des performances de blanchiment efficace sur des tâches sur des tissus sans transfert inacceptable des couleurs entre les tissus.
