A process for the preparation of fluid detergent product comprising an anionic surfactant in which the acid precursor of the anionic surfactant is fed through at least two mixing devices, sufficient neutralising agent to neutralise 25-75 wt% of the acid precursor being fed to the first mixing device, and sufficient neutralising agent to complete neutralisation being added to the mixture from the first mixing device to substantially complete neutralisation by the time the process stream exits the final mixing device, wherein the initial liquid component and the process stream are kept at pumpable temperature at all times during the process.

L'invention concerne un procédé de préparation d'un produit détergent fluide, comprenant : un tensioactif anionique dont le précurseur d'acide est alimenté par au moins deux dispositifs de mélange, un agent de neutralisation en quantité suffisante pour neutraliser 25 à 75 % en poids du précurseur d'acide amené dans le premier dispositif de mélange, et un agent de neutralisation en quantité suffisante pour compléter la neutralisation, ajouté au mélange sortant du premier dispositif de mélange afin de compléter sensiblement la neutralisation au moment où le flux du procédé sort du dernier dispositif de mélange, le composant liquide initial et le flux du procédé étant maintenus durant tout le procédé à une température telle qu'ils peuvent être pompés.
