Abstract: front page image
(EN)A process to manufacture a liquid detergent composition thickened with a linear and or cross linked alkali swellable polyacrylate copolymer wherein the composition comprises anionic surfactant comprising linear alkylbenzene sulfonate formed by neutralisation of linear alkylbenzene sulfonic acid during the process by one or more amines, the process comprising the steps of: a) Mixing the alkali swellable polyacrylate copolymer with water, then b) Further mixing at least one amine with the mixture of step a) the amount of amine being more than sufficient to neutralise the linear alkyl benzene sulfonic acid, and then c) Adding the linear alkylbenzene sulfonic acid to the thickened mixture of step b) thereby to form the corresponding anionic surfactant by neutralisation.
(FR)La présente invention concerne un procédé pour fabriquer une composition de détergent liquide épaissie avec un copolymère de polyacrylate gonflable par alcali linéaire et/ou réticulé, la composition comprenant un tensioactif anionique comprenant un alkylbenzènesulfonate linéaire formé par neutralisation d'acide alkylbenzènesulfonique linéaire pendant le processus par une ou plusieurs amines, le procédé comprenant les étapes de : a) mélange du copolymère de polyacrylate gonflable avec de l'eau, puis b) ensuite, mélange d'au moins une amine avec le mélange de l'étape a), la quantité d'amine étant plus que suffisante pour neutraliser l'acide alkylbenzènesulfonique linéaire, et ensuite c) ajout de l'acide alkylbenzènesulfonique linéaire au mélange épaissi de l'étape b) de manière à former le tensioactif anionique correspondant par neutralisation.
