The invention provides liquid hard surface cleaning compositions comprising multiple partial compositions held separately from each other in a multiple compartment container which is provided with a non-spray dispensing system. One partial composition comprises a peroxygen bleach compound, preferably hydrogen peroxide. The total composition comprises a multi-component thickening system of which the components are divided over the partial compositions in such a way that the total composition thickens on dispensing. Each partial composition has a pH at which the components in it are stable, while after mixing the total composition has a pH suitable for cleaning. The compositions preferably contain a quaternary imine salt bleach activator and a detergent surfactant. The number of partial compositions and of the compartments in the container is preferably 2.
La présente invention a pour objet des compositions liquides de nettoyage de surfaces dures comportant plusieurs compositions partielles conservées séparément dans un conteneur à plusieurs compartiments. Ledit conteneur est muni d'un système de distribution sans pulvérisation. Une composition partielle renferme un composé de blanchiment peroxygéné, de préférence du peroxyde d'hydrogène. La composition totale renferme un système épaississant à plusieurs composants répartis dans les compositions partielles de manière à épaissir au moment de sa distribution. Le pH de chaque composition partielle est tel que ses composants sont stables, la composition totale ayant, après mélange, un pH convenant au nettoyage. De préférence, les compositions contiennent un activateur de blanchissement à base de sel d'imine quaternaire et un agent tensio-actif détergent. De préférence, le nombre de compositions partielles et de compartiments dans le conteneur est de deux.
