The present invention provides a detergent granule and tablets which comprises an anionic surfactant system which comprises an anionic sulphate surfactant and/or an anionic sulphonate surfactant and other detergent active ingredients, the granule comprising at least a first and a second particulate component and optionally a binding agent, characterised in that the ratio of anionic sulphate surfactant to anionic sulphonate surfactant in the particulate components and in the optional binding agent is less than 1:4 or more than 4:1, preferably even less than 1:5 or more than 5:1. The invention also relates to specific granules comprising restricted degree of mixing of anionic sulphonate surfactant and zeolite, anionic sulphate surfactant and carbonate salts and/or restricted degree of mixing of polymeric builder and anionic surfactant, in particular sulphate surfactants.

La présente invention concerne un détergent sous forme de granulés ou de pastilles comprenant un système tensioactif anionique renfermant un agent tensioactif sulfate anionique et/ou un agent tensioactif sulfonate anionique et autres ingrédients actifs détergents. Lesdits granulés renferment au moins un premier et un second composants particulaires et éventuellement, un liant. Ce détergent est caractérisé en ce que le rapport entre l'agent tensioactif sulfate anionique et l'agent tensioactif sulfonate anionique dans les composants particulaires et dans le liant facultatif est inférieur à 1:4 ou supérieur à 4:1, voire de préférence inférieur à 1:5 ou supérieur à 5:1. L'invention concerne également des granulés spécifiques comprenant un degré limité de mélange de l'agent tensioactif sulfonate anionique et de zéolites, de l'agent tensioactif sulfate anionique et de sels de carbonate et/ou un degré limité de mélange d'un adjuvant polymère et d'un agent tensioactif anionique, en particulier des tensioactifs sulfate.
