Definitions
- the present invention is in the field of machine dishwashing. More specifically, the invention encompasses automatic dishwashing detergents and their use in a dish washing process.
- a consumer would use three products to wash dishes in an automatic dishwashing machine.
- Salt would be added to the salt compartment to soften water.
- a dishwashing detergent composition would serve to clean the articles, and a rinse aid would be used in the final steps of the dishwashing process to avoid streaks and smears on the articles.
- "4 in 1" products comprise, in addition to the ingredients of the "3 in 1" products, a glass protection agent.
- a builder generally serves to improve and extend the action of surfactant.
- a builder may provide this contribution in a number of ways, e.g. by binding of calcium and magnesium ions, binding of transition metal ions, peptisation and suspension of soil in solution, provision of alkalinity and structuring/solubilising powder. The binding of calcium and magnesium is the most relevant function among these.
- Suitable replacers include carbonate, citrate, zeolite, silicate and amino polycarboxylic compounds such as methylglycine diacetic acid (MGDA) and variants thereof e.g. NTA (nitrile triacetic acid), GDA (glutamic diacetic acid), DPA (dipicolinic acid) and IDS (imino disuccinic acid).
- MGDA methylglycine diacetic acid
- NTA nitrile triacetic acid
- GDA glutmic diacetic acid
- DPA dipicolinic acid
- IDS amino disuccinic acid
- citrate The most common replacer of phosphate builder is citrate.
- a drawback of the inclusion of citrate is that its functionality is not optimal in a hard water environment. Natural water contains calcium and magnesium ions which can act as counterion to carbonate. Under certain conditions this may lead to the precipitation of calcium/magnesium carbonate. This precipitate is white on glass and washware and is certainly not desired by consumers. The level of these cations is referred to as the total hardness of water which is expressed as milligrams of equivalent calcium carbonate (Mw 100) per liter (ppm).Reference is made to L.S. Clesceri et al, Standard methods for the examination of water and wastewater, 17th edition, American Public Health Association, Washington DC, 1989 . The hardness of natural waters can range from only a few ppm up to over 400 ppm in some areas.
- the invention relates to a multifunctional dishwashing composition for use in an automatic dish washer, said composition being essentially free of phosphates, wherein the composition comprises
- the invention further relates to a method for washing articles in a mechanical dishwashing machine comprising treating the articles with a wash liquor comprising the composition according to the invention.
- the invention relates to a packaging unit comprising a pack comprising the dishwashing composition according to the invention.
- the invention relates to the use of a composition according to the invention in an automatic dishwashing machine so no salt is required for rejuvenation of ion exchange material within the machine.
- citrate or aminocarboxylic compound or another acid this is intended to encompass the acid, a salt thereof or a combination.
- compositions according to the invention comprise a builder.
- the compositions are essentially free of phosphate and therefore another builder is included.
- essentially free of phosphate is defined as containing less than 1 wt% phosphate-compound on total weight of the composition.
- phosphate containing compounds are tripolyphosphates, polyphosphates, hexametaphosphate, orthophosphate, and the alkalimetal (preferably sodium) salts thereof.
- the builder functionality in these compositions is found in the combination of the amino polycarboxylic compound and citrate.
- the amount of citrate is from 30 to 70 wt% on the total weight of citrate and amino polycarboxylic compound.
- the amount of citrate is from 40 to 60 wt% on the total weight of citrate and amino polycarboxylic compound.
- the total level of citrate in the compositions is preferably from 10 to 30 wt%, more preferred from 10 to 25 wt%.
- the total level of amino polycarboxylic compound is preferably from 10 to 40 wt%, more preferred from 20 to 30 wt% on total weight of the composition.
- Citrate is preferably present in the form of its sodium salt.
- the amino polycarboxylic compound is selected fom MGDA and IDS.
- the most preferred type of amino polycarboxylic compound is MGDA.
- the composition comprises a further builder which may be selected for example from the group comprising alkali metal carbonates, bicarbonates, borates and zeolites.
- the composition comprises from 0 to 5 wt% of silicate.
- silicate is present in amounts up to 30 wt% or even higher, around 50 wt%. Purpose of the silicate in those known compositions is often to prevent fading of colours on glaze porcelain and decorated glasses via corrosion, as well as on enamel and metal corrosion.
- the amount of silicate present in the composition of the current invention should be far less than 30 wt%, most preferably even as low as possible, while use of the machine dishwash detergent composition of the invention does not lead to negative effects from the reduction or even omission of silicate compounds in said composition.
- the machine dishwash detergent composition of the invention does not lead to negative effects from the reduction or even omission of silicate compounds in said composition.
- silicium compounds in the form of silicate there is a maximum amount of silicium compounds in the form of silicate to be present.
- the total amount of silicate present is 5 wt%. If any silicate is present in the composition or the process of the current invention, it is preferred that the silicate is chosen from the group of alkali metal silicates.
