Kendt teknik 20 US 7211552 B1 beskriver en ikke-toksisk, miljøvenlig, enzymatisk rengøringssammensætning til rengøring af kirurgiske instrumenter. Sammensætningen indeholder 64-68% vand, 1-2% natriumformiat, 4-6% natriumtripolyfosfat, 0,1-0,3% calciumklorid, 3-5% protease og 1-3% amylase. Sammensætningen ifølge 25 den foreliggende opfindelse adskiller sig herfra ved at indeholde væsentligt mere formiat og mindre enzym.Prior art US 7211552 B1 discloses a non-toxic, environmentally friendly, enzymatic cleaning composition for cleaning surgical instruments. The composition contains 64-68% water, 1-2% sodium formate, 4-6% sodium tripolyphosphate, 0.1-0.3% calcium chloride, 3-5% protease and 1-3% amylase. The composition of the present invention differs from this by containing substantially more formate and less enzyme.
WO 2008/116915 beskriver en enzymsammensætning indeholdende et enzym, en inhibitor bestående af phenylborsyre eller et derivat deraf og 0,1-20% af et 30 opløst salt. Det opløste salt anvendes til at forbedre effekten af phenylborsy-reinhibitoren. Sammensætningen kan anvendes som maskinopvaskemiddel. Sammensætningen ifølge den foreliggende opfindelse adskiller sig herfra ved at DK 177132 B1 2 indeholde en begrænset mængde enzym samt mindst 25% af et opløst salt, hvoraf mindst 20% af sammensætningen udgøres af et formiatsalt.WO 2008/116915 discloses an enzyme composition containing an enzyme, an inhibitor consisting of phenylboronic acid or a derivative thereof and 0.1-20% of a dissolved salt. The dissolved salt is used to enhance the effect of the phenylboronic reinhibitor. The composition can be used as a machine dishwasher detergent. The composition of the present invention differs from this in that DK 177132 B1 2 contains a limited amount of enzyme as well as at least 25% of a dissolved salt, of which at least 20% of the composition is a formate salt.

3. Om opfindelsen 10 3.1 Teknisk område3. About the invention 10 3.1 Technical field
Opfindelsen angår en væske - et såkaldt opvaskemiddel til anvendelse i opvaskemaskiner. Der er tale om alle typer af maskiner, hvor der sker en løbende dosering under selve vaskeprocessen.The invention relates to a liquid - a so-called detergent for use in dishwashers. These are all types of machines where continuous dosing is done during the washing process itself.

Opvaskemidlet finder anvendelse i maskiner og i private hjem, men som oftest vil der være tale om større, industrielle opvaskemaskiner og opvasketunneler.The detergent is used in machines and in private homes, but most often it will be large industrial dishwashers and dishwashers.
De findes typisk i restauranter, kantiner, hotelkøkkener og lignende steder.They are typically found in restaurants, canteens, hotel kitchens and similar places.
20 Opvaskemidlet i processen har flere funktioner. Det skal reducere overfladespændingen i vandet, for derved at øge vandets vaskeeffekt. Det skal desuden aktivt medvirke til at løsne de forskellige former for snavs, der består af de forskellige stoffer, der indgår i drikke- og fødevarer, bl.a. fedt, proteiner m.v.20 The detergent in the process has several functions. It should reduce the surface tension in the water, thereby increasing the washing power of the water. In addition, it must actively contribute to loosening the various forms of dirt, which consist of the various substances contained in beverages and foods, including fat, proteins, etc.
25 Væsken skal også kunne fjerne belægninger, der for eksempel opstår i kaffe og tekopper, efter længere tids brug - uden opvask - og det skal sikre, at vandet og dermed kalken ikke binder i overfladen, hvorved der dannes synlige grå aflejringer f.eks. drikkeglas.25 The liquid must also be able to remove coatings, which occur, for example, in coffee and teacups, after prolonged use - without washing up - and it must ensure that the water and thus the lime does not bond to the surface, thereby forming visible gray deposits, e.g. drinking glasses.
30 Væsken skal desuden sikre, at løsnet snavs ikke senere sætter sig i vaskeemnerne under vaskeprocessen og endelig skal eventuelle reststoffer være uskadelige i forbindelse med brug af servicen.30 The liquid must also ensure that loosened dirt does not settle later in the wash items during the washing process and finally any residual substances must be harmless in connection with the use of the service.

Disse egenskaber skal alle være til stede uanset hvilket materiale servicen består af, f.eks. metallegeringer som rustfrit stål, aluminiumsgryder, porcelæn, glas, plastik osv. Væskens påvirkning af disse materialer skal være neutral, således der ikke dannes misfarvninger på servicen.These properties must all be present regardless of the material of the service, e.g. metal alloys such as stainless steel, aluminum pots, porcelain, glass, plastic, etc. The influence of the liquid on these materials must be neutral, so that no discoloration of the service is formed.

Der eksisterer i dag allerede midler, der tilgodeser mange af ovenstående krav - men fælles for alle disse midler er at de er baseret på højt alkali (dvs. pH14) og dermed et meget aggressivt miljø. Ligeledes har mange af produkterne tilsætning af chlor for at opnå en yderligere rensende effekt. Udover den høje pH 10 er midlerne således også skadelig for mennesker og miljø.Today, agents already exist that meet many of the above requirements - but common to all these agents is that they are based on high alkali (ie pH14) and thus a very aggressive environment. Also, many of the products have the addition of chlorine to obtain a further purifying effect. In addition to the high pH 10, the agents are also harmful to humans and the environment.
3.2 Kort beskrivelse af opfindelsen3.2 Brief Description of the Invention
Det har nu vist sig, at der er muligt at fremstille et koncentrat, som er miljøven-15 ligt og hvor koncentratet i modsætning til hidtil kendte midler kan anvendes til alle typer for maskinopvask uden brug af høj alkali eller chlor.It has now been found that it is possible to prepare a concentrate which is environmentally friendly and in which the concentrate, contrary to known means, can be used for all types of machine washing without the use of high alkali or chlorine.
Koncentratet omfatter enzymer, salte og vand, justeret til pH på ca. 8,5.The concentrate comprises enzymes, salts and water, adjusted to a pH of approx. 8.5.
20 Opfindelsen angår således et enzymbaseret saltholdigt maskinopvaskemiddel omfattende op til 2% enzymer at typen amylase og protease, 5-10 % uorganiske salte valgt blandt natriumchlorid og kaliumtripolyfosfat, 20-25% formiat og resten vand.The invention thus relates to an enzyme-based saline dishwashing detergent comprising up to 2% enzymes of type amylase and protease, 5-10% inorganic salts selected from sodium chloride and potassium tripolyphosphate, 20-25% formate and the remainder water.
25 Væsken tilsættes maskinopvaskemaskinen som koncentrat og påføres vaskeprocessen via konduktiviteten i vaskevandet.The liquid is added to the machine dishwasher as a concentrate and applied to the washing process via the conductivity of the washing water.
Væsken har den fordel, at det blødgør vandet og reducerer overfladespændingen. Endvidere eliminerer midlet kalkaflejringer fra vandet. Opvaskemidlet er 30 desuden temperaturstabilt og kan være effektivt ved lavere temperaturer. Det er stabilt under transport og opbevaring, og endelig er det ikke korroderende eller giver misfarvninger på forskellige materialer som plastik, glas, porcelæn, diverse metallegeringer m.v.The liquid has the advantage of softening the water and reducing the surface tension. Furthermore, the agent eliminates lime deposits from the water. In addition, the detergent is temperature stable and can be effective at lower temperatures. It is stable during transport and storage, and finally it is not corrosive or discolorable on various materials such as plastic, glass, porcelain, various metal alloys etc.
