Title (EN) LIQUID DETERGENT AND CLEANING AGENT COMPOSITION
(FR) COMPOSITION DE DETERGENT LIQUIDE ET D'AGENT DE NETTOYAGE
Abstract:
(EN) The invention relates to liquid detergent and cleaning agent compositions of high storage stability. They comprise a liquid medium with a water content of up to 15 wt.% and particulate coating bleaching agents suspended therein. The bleaching agent has a dissolving time of at least 5 minutes and a coating of at least two layers: The innermost layer comprises one or more hydrate-forming inorganic salts as the main component(s), and an outer layer, which makes up 0.2 to 5 wt.% of the coated bleaching agent, comprises alkali metal silicate(s) with a modulus of SiO2 to M2O (M = alkali metal) of greater than 2.5 as the main component(s). Preferred compositions comprise sodium percarbonate with an innermost layer of substantially sodium sulfate and an outermost layer of substantially 0.5 to 1.5 wt.% sodium silicate (modulus 3.2 to 4.2) as the bleaching agent.
(FR) L'invention concerne des composition de détergent liquide et d'agent de nettoyage offrant une grande stabilité au stockage. Ces compositions comprennent un milieu liquide d'une teneur en eau maximum de 15 % en poids et des agents de blanchiment à revêtement particulaire en suspension. L'agent de blanchiment a une durée de dissolution d'au moins 5 minutes, avec un dépôt d'au moins deux couches: La couche intérieure comprend comme élément(s) principal(aux) un ou plusieurs sels inorganiques formant des hydrates, et une couche extérieure représentant de 0,2 à 5.% en poids de l'agent de blanchiment déposé et comprenant un ou des silicates de métal alcalin avec un module de SiO2 à M2O (M = métal alcalin) supérieur à 2,5 en tant que composant(s) principal(aux). Les compositions préférées comprennent un percarbonate de sodium avec une couche intérieure composée sensiblement de sulfate de sodium et une couche extérieure comprenant sensiblement de 0,5 à 1,5 % en poids de silicate de soude (module de 3,2 à 4,2) comme agent de blanchiment.
