Abstract
Description
- The present invention relates to an improvement in the rinse step of machine dishwashing operations.
- Usually in machine dishwashing operations, the articles to be cleaned are first cleaned in a main wash step, and subsequently rinsed several times to rinse away any adhering main wash product and remaining soil. It is customary to add to the rinsing water a rinse aid composition which causes the articles to dry more evenly and improves the visual appearance of the articles when dry. Although such rinse aid compositions improve said visual appearance in comparison with articles which have not been rinsed with a rinse aid containing rinse liquor, said visual appearance may still need improvement, as, despite the use of a rinse aid, some film-and spot-formation may still occur.
- It has now been found that the use of an effective level of a layered clay in the rinse step of the machine dishwashing operation significantly reduces the formation of spots on the rinsed articles when dry.
- The present invention therefore relates to an improved rinse step in a machine dishwashing operation, wherein the improvement comprises the use, in the rinse liquor, of an effective amount of a layered clay.
- Rinsing of the cleaned articles with a rinse liquor which comprises such an effective amount of a layered clay reduces the formation of spots on the articles when dry.
- The layered clay minerals suitable for use in the present invention 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, pyro- phyllite, hectorite, saponite, sauconite, nontron- ite, talc, beidellite, volchonskoite, vermiculite;
- kaolins, e.g. kaolinite, dickite, nacrite, antigor- ite, anauxite, halloysite, indellite, chrysotile;
- illites, e.g. bravaisite, muscovite, paragonite, phlogopite, biotite;
- chlorites, e.g. corrensite, penninite, donbassite, sudoite, pennine, clinochlore;
- attapulgites, e.g. sepiolite, polygorskyte;
- mixed layer clays, e.g. allevardite, vermiculite- biotite.
- The layered clay minerals may be either naturally occurring or synthetic. Preferred clay minerals for use in the present invention are natural or synthetic hectorites, montmorillonites and bentonites, and of these the hectorites are especially preferred. Many of the above clays are commercially available, and typical examples of commercial hectorites are the Laponites ex Laporte Industries Ltd, England; Veegum Pro and Veegum F ex R.T. Vanderbilt, U.S.A.; the Barasyms, Macaloids and Propaloids ex Baroid Division, National Read Comp., U.S.A.
- Particularly preferred commercial hectorites are Laponite S, Laponite XLS, Laponite RD and Laponite RDS, of which Laponite XLS is especially preferred. This is a synthetic hectorite having the following characteristics: analysis (dry basis) Sio2 59.8%, MgO 27.2%, Na20 4.4%, Li20 0.8%, structural H20 7.7%, with the addition of tetrasodium pyrophosphate (6%); specific gravity 2.53; bulk density 1.0.
- The layered clay may be added to the rinse water as such, or it may be added thereto in the form of a liquid dispersion of the clay in water or in the form of a composition in any suitable physical form comprising the clay and other suitable or desirable ingredients. Such other suitable ingredients may be low levels of wetting or detergent surfactants, organic acids, hydrotropes, alcohols, perfumes, germicides, anticorrosion agents, etc. Suitable physical forms are powders, liquids, tablets, blocks, granulates, etc.
- The level of the layered clay in the rinse liquor should be such that the rinse liquor contains from 0.001-1 g of the clay per litre. The rinse liquor with the layered clay is effective at both higher and lower rinsing temperatures.
- The invention will be further illustrated by way of Example.
- A standard set of tumblers, soiled with a standard evaluation soil, was cleaned in a commercially available dishwashing machine, sold by Miele AG, Germany, under the name Miele G 550. The normal programme was used, at a temperature of 65°C. The water hardness was 9° German hardness. A commercially available machine dishwashing product was used at a dosage of 3 g/l.
- In one experiment, 0.05 g/1 of Laponite XLS was added to the final rinse water, and in another experiment no clay was added to the final rinse water.
- The tumblers when dry were visually assessed as to the spot formation, using the following scale:
- 1 = no spots
- 2 = 1-5 spots
- 3 = 6-10 spots
- 4 = 11-20 spots
- 5 = more than 20 spots.
-
-
-
-
- In the same manner as in Example 1, the following clays were tested in the final rinse at a concentration of 200 mg/10 1.
