Title
(EN) CONCENTRATED ALKALINE ISOTROPIC DETERGENT LIQUID WITH BLEACH
(FR) LIQUIDE DETERGENT, ISOTROPE, ALCALIN ET CONCENTRE COMPORTANT UN AGENT DE BLANCHIMENT
Abstract
(EN)
A concentrated alkaline isotropic fabric washing liquid detergent composition comprising at least 23 % of surfactants and further comprising at least 0.2 % hydrogen peroxide bleach, the composition is substantially free from hydrotropes which cause the pH to reduce and impair the effectiveness of the composition. Also a concentrated alkaline isotropic fabric washing liquid detergent composition comprising at least 15 % by weight of surfactant further comprises at least 0.2 % by weight hydrogen peroxide bleach and an optical brightener and is also substantially free from hydrotropes. The compositions may be used as a main wash bleaching liquid or a pretreatment liquid and may be activated with a bleach activator.
(FR)
Cette composition d'un liquide détergent, isotrope, alcalin, concentré et destiné au lavage de textiles comprend au moins 23 % de tensioactifs ainsi que 0,2 % d'un agent de blanchiment à base de peroxyde d'hydrogène, la composition étant essentiellement dépourvue d'hydrotropes provoquant l'abaissement du pH et compromettant l'efficacité du détergent. On décrit également une composition de liquide détergent, isotrope, alcalin, concentré, destiné au lavage de textiles et comprenant au moins 15 % en poids de tensioactifs, au moins 0,2 % en poids de peroxyde d'hydrogène ainsi qu'un azurant optique, cette composition étant également essentiellement dépourvue d'hydrotropes. On peut utiliser ces compositions en tant que liquide de blanchiment pour le lavage ou pour le prélavage, ce liquide pouvant être activé à l'aide d'un activateur du blanchiment.
