Definitions
- This invention relates to machine dish- and warewashing compositions. These compositions are used for the cleaning of housewares such as pots, pans, dishes, cups, saucers, bottles, glassware, crockery, cutlery and other kitchen utensils in automatic-dishwashing and warewashing machines. For brevity sake these compositions are referred to in the description as machine dishwashing compositions.
- Machine dishwashing compositions usually contain as main components a builder or builder mixture, buffering and/or alkaline agents, a bleaching agent which may be a chlorine or oxygen bleach, and lately also enzymes. Such machine dishwashing compositions are used in the main wash step of machine dishwashing and in general have a satisfactory cleaning performance.
- the layered clay minerals suitable for the above purpose of use belong to the geological classes of the smectites, the kaolins, the illites, the chlorites, the attapulgites and the mixed layer clays.
- Typical examples of specific clays belonging to these classes are:
- smectites e.g. montmorillonite, bentonite,pyrophylite, hectorite, saponite, sauconite, nontronite, talc, beidellite, volchonskoite, vermiculite; kaolins, e.g. kaolinite, dickite, nacrite, antigorite, anauxite, halloysite, indellite, chrysotile; illites, e.g. bravaisite, muscovite, paragonite, phlogopite, biotite; chlorites, e.g.

- a 30% Sokalan CP5 solution was used as liquid binder and in another experiment a 34% Sokalan CP5 solution was used.
- the liquid binder was dosed at a gradually increasing flow rate, until (after approx. 2 minutes) the granulates looked good. Then the liquid feed was kept constant and the wet granulate was charged to the fluid bed drier. At a reasonable fill of the fluid bed (approx. 30 kg) the granulation was stopped and drying continued until the bed temperature was 50°C.
- Each experiment was dried at two water contents of 5% and 10% by weight .
- the appearance of the filter and weight of residue on the filter were determined after 20 repeat washes.
- Laponite clay granulated according to the invention gave no or substantially no clay build-up on the filter.

Abstract
L'invention concerne des compositions en poudre pour le lavage en machine de la vaisselle se composant d'argile stratifiée se présentant sous la forme de particules granulées obtenues par: 1) cogranulation d'une argile finement divisée avec une matière particulaire solide, au moyen d'une matière polymère soluble dans l'eau utilisée comme liant; 2) conglutination d'une argile finement divisée avec du disilicate de sodium en tant que liant, au moyen d'un agent tensioactif non ionique soluble dans l'eau utilisé comme liant; ou 3) granulation d'une argile finement divisée avec de l'eau ou une solution de silicate alcalin. Les particules d'argile granulées se dispersent bien, ne se déposent pas sur le filtre du lave-vaisselle et ne risquent donc pas de le boucher.
