The present invention relates to a process for preparing granular detergent products in which a liquid binder component comprising an acid precursor of an anionic surfactant and a hydrotrope is contacted with a solid particulate starting material comprising a neutralising agent in a low shear mixer and the mixture granulated, the hydrotrope being present at a level of at least 1 % by weight of the acid precursor of the anionic surfactant.

L'invention concerne un procédé de préparation de produits détergents en grains dans lequel un composant de liaison liquide contenant un précurseur acide d'un tensioactif anionique et un hydrotrope est mis en contact, dans un mélangeur à faible cisaillement, avec une matière de base particulaire solide contenant un agent de neutralisation. L'invention concerne également le mélange en grains ainsi obtenu, dans lequel l'hydrotrope est présent à un taux d'au moins 1 % en poids du précurseur acide du tensioactif anionique.
