Patent

CA 2305565

The present invention relates to compositions comprising a peroxygen bleach, a chelating agent having a mobility factor greater or equal to 0.7 and a chelating agent having a mobility lower than 0.6, characterised in that the weight ratio of the chelating agent having a mobility factor greater or equal to 0.7 to the chelating agent having a mobility factor lower than 0.6 is of more than 1:1. These compositions are particularly suitable for the cleansing of carpets, resulting in effective overall stains removal performance for example on particulate stains and/or greasy/oil and/or bleachable stains and/or enzymatic stains while proving improved colour fidelity.

La présente invention a trait à des compositions contenant un agent de blanchiment peroxyde, un agent chélatant possédant un facteur de mobilité supérieur ou égal à 0,7 et un agent chélatant possédant un facteur de mobilité inférieur à 0,6. Les compositions sont caractérisées par le fait que le rapport en poids de l'agent chélatant à facteur de mobilité supérieur ou égal à 0,7 sur l'agent chélatant à facteur de mobilité inférieur à 0,6 est supérieur à 1:1. Ces compositions conviennent particulièrement pour le nettoyage de tapis, et permettent d'obtenir des performances efficaces d'élimination de taches, par exemple sur des taches de matières particulaires et/ou graisseuses/huileuses et/ou des taches pouvant être blanchies et/ou des taches enzymatiques, tout en assurant une conservation accrue des couleurs.
