The invention concerns a liquid agent in suspension for use in washing-up machines. The aim of the invention is to ensure the consistency of a paste without the need to use thickeners or extenders. This is achieved by using 30 to 60 % by wt. of water, 15 to 70 % by wt. of an alkali-metal tripolyphosphate selected from sodium tripolyphosphate, used either in the anhydrous or the partly hydrated form, and potassium tripolyphosphate in the presence of 5 to 30 % by wt. of an alkali carrier such as an alkali-metal hydroxide, carbonate or metasilicate, if necessary in the presence or active-chlorine carriers, complex carriers and the other usual auxiliaries.
L'invention vise à produire un nettoyant liquide en suspension, à utiliser en lave-vaisselle ou pour d'autres opérations de nettoyage, dont la consistance soit pâteuse, sans faire appel à des épaississants ou à des charges. A cet effet, on utilise entre 30 et 60 % en poids d'eau, entre 15 et 70 % en poids d'un tripolyphosphate de métal alcalin, sélectionné parmi le tripolyphosphate de sodium, qui est utilisé sans eau ou partiellement hydraté, ou le tripolyphosphate de potassium en présence d'entre 5 et 30 % en poids d'un support alcalin tel que lessive alcaline, carbonate alcalin ou métalsilicate alcalin, de préférence en présence de supports au chlore actif, de supports de complexes et d'autres agents auxiliaires habituels.
