The present invention relates to granular detergent compositions and in particular low density, phosphate-containing detergent compositions, which comprise a specific bleaching system containing hydrophobic peracid bleach and hydrophilic peracid bleach and a peroxide source, having specific low levels of available oxygen from hydrophobic and hydrophilic peroxyacid bleach, specific ratios of available oxygen from the hydrophobic peracid bleach to the hydrophilic peracid bleach and specific ratios of available oxygen of the peroxide source to the available oxygen of the peracids. The invention also relates to the use of specific mixed bleach systems for sanitisation or reduction of the bacterial activity.
L'invention concerne des compositions détergentes granulaires et plus particulièrement, des compositions détergentes renfermant du phosphate, de faible densité, qui comprennent un système spécifique de blanchiment renfermant un agent de blanchiment peracide hydrophobe et un agent de blanchiment peracide hydrophile et une source peroxyde, présentant des niveaux spécifiques faibles d'oxygène disponible à partir de l'agent de blanchiment de peroxyacide hydrophobe et hydrophile, un rapport spécifique d'oxygène disponible entre l'agent de blanchiment peracide hydrophobe et l'agent de blanchiment peracide hydrophile et un rapport spécifique d'oxygène disponible entre la source peroxyde et l'oxygène disponible des peracides. L'invention concerne aussi l'utilisation de systèmes de blanchiment spécifiques mélangés permettant de nettoyer ou de réduire l'activité bactérienne.
