Title (EN) METHOD OF MAKING A DETERGENT COMPOSITION
(FR) PROCÉDÉ DE FABRICATION D’UNE COMPOSITION DÉTERGENTE
Abstract:
(EN) The present invention provides a method of making a detergent composition, the method comprising the following steps in the recited order: (a) providing an aqueous composition comprising a citrate salt; (b) lowering the pH by adding a first, un-neutralised or partially neutralised, polyacrylic acid having a weight average molecular weight in the range of 1000 to 6000 to form a second mixture; (c) increasing the pH by adding alkali metal carbonate and/or alkali metal bicarbonate to form a third mixture; and (d) adding a second polyacrylic acid having a weight average molecular weight in the range of 1000 to 6000 to form a fourth mixture; wherein the detergent composition is preferably an automatic dishwashing detergent composition or a laundry detergent composition.
(FR) La présente invention décrit un procédé de fabrication d’une composition détergente, le procédé comprenant les étapes suivantes dans l’ordre énoncé : (a) la fourniture d’une composition aqueuse comprenant un sel citrate ; (b) la réduction du pH en ajoutant un premier, poly(acide acrylique), non neutralisé ou partiellement neutralisé, présentant un poids moléculaire moyen en poids situé dans la plage de 1 000 à 6 000 pour former un second mélange ; (c) l’augmentation du pH en ajoutant du carbonate de métal alcalin et/ou du bicarbonate de métal alcalin pour former un troisième mélange ; et (d) l’addition d’un second poly(acide acrylique) présentant un poids moléculaire moyen en poids situé dans la plage de 1 000 à 6 000 pour former un quatrième mélange ; la composition détergente étant préférablement une composition détergente pour lave-vaisselle automatique ou une composition détergente de blanchisserie.
