Description
Denne oppfinnelse angår nye vaskemiddelblandinger som egner seg for anvendelse i oppvaskmaskiner, og en fremgangsmåte for fremstilling av disse. This invention relates to new detergent mixtures which are suitable for use in dishwashers, and a method for their production.
Vaskeoperasjonen i en vaskemaskin involverer både den rensende virkning av vaskemidlet og den mekaniske virkning av vannet. I tillegg til vaskeevne må vaskemidlet ha desin-fiserende evne og vannbløtgjørende egenskaper. Vaskemidlet må derfor ha en sterk renseevne, men dets sammensetning må også være slik at det ikke forårsaker dannelse av skum som vil ha uhelding innvirkning på den mekaniske virkning av vaskevannet. Dette er årsakene til at vaskemiddelblandinger som i og for The washing operation in a washing machine involves both the cleaning effect of the detergent and the mechanical effect of the water. In addition to washing ability, the detergent must have disinfecting ability and water-softening properties. The detergent must therefore have a strong cleaning ability, but its composition must also be such that it does not cause the formation of foam which will have an adverse effect on the mechanical effect of the washing water. These are the reasons why detergent mixtures such as in and for
seg kjent utgjøres av:is known to consist of:
- Et bløtgjørende middel, som vanligvis velges blant polyfosfatér. (Blant de polyfosfater som benyttes, kan nevnes natriumtripolyfosfat, natriumhexametafosfat og natriumpyrofos-fat samt de tilsvarende kaliumpolyfosfater.) - Et alkaliserende middel bestående av et natriummetasilicat i vannfri form eller i form av pentahydratet. (Som i og for seg kjent kan natriumsilicat erstattes delvis med natriumcarbonat, natriumsulfat eller natriumhydroxyd.) - Et ikke-skummende overflateaktivt middel av ikke-ionisk type, valgt blant de følgende materialer: ethoxylérte lineære alkoholer, kondensater av ethylenoxyd og propylenoxyd, alkoxyaminer, polyethoxyetere av fettalkoholer, ethoxylérte alkylfenoler og fosforsyreestere av fettalkoholer. Med tanke på effektivitet, biologisk nedbrytbarhet og kostnadsnivå fore-trekkes det å benytte et overflateaktivt middel valgt blant ethoxylérte lineære alkoholer. - A softening agent, which is usually chosen from among polyphosphates. (Among the polyphosphates used, mention may be made of sodium tripolyphosphate, sodium hexametaphosphate and sodium pyrophosphate as well as the corresponding potassium polyphosphates.) - An alkalizing agent consisting of sodium metasilicate in anhydrous form or in the form of the pentahydrate. (As is known in and of itself, sodium silicate can be partially replaced by sodium carbonate, sodium sulfate or sodium hydroxide.) - A non-foaming surfactant of a non-ionic type, selected from the following materials: ethoxylated linear alcohols, condensates of ethylene oxide and propylene oxide, alkoxyamines, polyethoxyethers of fatty alcohols, ethoxylated alkylphenols and phosphoric acid esters of fatty alcohols. In view of efficiency, biodegradability and cost level, it is preferred to use a surface-active agent selected from among ethoxylated linear alcohols.
- Et desinfeksjonsmiddel.- A disinfectant.
Desinfeksjonsmidlet som benyttes, og som frigjør aktivt klor, er vanligvis et fast materiale på klorbasis av klorisocyanuratderivat-typen. Dette er som oftest et natrium- eller kalium-salt av diklorisocyanursyre. The disinfectant used, which releases active chlorine, is usually a solid chlorine-based material of the chloroisocyanurate derivative type. This is usually a sodium or potassium salt of dichloroisocyanuric acid.
Hittil er de følgende blitt benyttet i praksis: vannfritt natriumdiklorisocyanurat som ved titrering gir -63% aktivt klor, et natriumdiklorisocyanurat-dihydrat som ved . titrering gir 56% aktivt klor, vannfritt kaliumdiklorisocyanu-rat som ved titrering gir 59% aktivt klor, kaliumdiklorisocya- So far, the following have been used in practice: anhydrous sodium dichloroisocyanurate, which on titration gives -63% active chlorine, a sodium dichloroisocyanurate dihydrate which at . titration gives 56% active chlorine, anhydrous potassium dichloroisocyanurate which on titration gives 59% active chlorine, potassium dichloroisocyanurate
nurat-monohydrat som ved titrering gir 56% aktivt klor eller kalsiumdiklorisocyanurat-tetrahydrat som ved titrering gir 56% aktivt klor. Det aktive klor defineres som den oxyderende evne, fordi kloret er positivt. Kloret som er tilstede i de ovenfor omtalte klorerte derivater, er bundet til et nitrogen-atom og er således tilstede i derivatene i oxydasjonstilstanden +1, det vil si som Cl<+>. Under oxydasjonsprosessen binder et Cl<+>—ion til seg to elektroner, slik at det overføres til Cl" nurate monohydrate which on titration gives 56% active chlorine or calcium dichloroisocyanurate tetrahydrate which on titration gives 56% active chlorine. Active chlorine is defined as the oxidizing ability, because chlorine is positive. The chlorine that is present in the above-mentioned chlorinated derivatives is bound to a nitrogen atom and is thus present in the derivatives in the oxidation state +1, that is as Cl<+>. During the oxidation process, a Cl<+> ion binds to itself two electrons, so that it is transferred to Cl"
(klorid). To ekvivalenter av et oxydasjonsmiddel frigjøres, hvilket svarer til 71 g elementært klor, selv om atomveksten bare er 35,5. Dette innebærer også at et atom Cl<+>har samme oxyderende evne som et molekyl elementært klor Cl^'(chloride). Two equivalents of an oxidizing agent are liberated, corresponding to 71 g of elemental chlorine, although the atomic growth is only 35.5. This also implies that an atom of Cl<+> has the same oxidising ability as a molecule of elemental chlorine Cl^'
Blant de øvrige klorerte desinfeksjonsmidler av kloriso-cyanuratgruppen finnes der ett som ved titrering gir ca. 91% aktivt klor, nemlig triklorisocyanursyre. Det ville derfor være fordelaktig å kunne benytte denne, tatt i betraktning det høye prosentvise innhold av aktivt klor. Dessverre har den hittil ikke kunnet benyttes, da den har vært for reaktivt overfor de øvrige komponenter av vaskemiddelblandingene, spesielt overfor de overflateaktive midler. Vaskemiddelblandinger som inneholder triklorisocyanursyre, er lagringsustabile, og de taper betydelige mengder både av klor og av overflateaktive midler som følge av gjensidig ødeleggelse. Among the other chlorinated disinfectants of the chlorisocyanurate group, there is one which, by titration, gives approx. 91% active chlorine, namely trichloroisocyanuric acid. It would therefore be advantageous to be able to use this, considering the high percentage content of active chlorine. Unfortunately, it has so far not been able to be used, as it has been too reactive towards the other components of the detergent mixtures, especially towards the surfactants. Detergent compositions containing trichloroisocyanuric acid are storage unstable, and they lose significant amounts of both chlorine and surfactants as a result of mutual destruction.
En måte å stabilisere triklorisocyanursyre på er nu blitt funnet, spesielt for stabilisering av denne for fremstilling av vaskemiddelblandinger som er lagringsstabile og egnede for anvendelse i oppvaskmaskiner. A way of stabilizing trichloroisocyanuric acid has now been found, especially for stabilizing this for the production of detergent mixtures which are storage stable and suitable for use in dishwashers.
I henhold til oppfinnelsen tilveiebringes det således en ny vaskemiddelblanding som er anvendelig i oppvaskmaskiner, og som inneholder et bløtgjøringsmiddel valgt blant polyfosfatene, et alkaliserende middel valgt blant natriumsilicatene, et ikke-ionisk overflateaktivt middel og et klorisocyanuratderivat. Den nye vaskemiddelblanding utmerker seg ved at den benyttede triklorisocyanursyre er overtrukket med en parafinvoks anvendt i en konsentrasjon av fra 1 til 10 vekt% beregnet på vekten av syren. According to the invention, a new detergent mixture is thus provided which can be used in dishwashers, and which contains a softening agent selected from the polyphosphates, an alkalizing agent selected from the sodium silicates, a non-ionic surfactant and a chloroisocyanurate derivative. The new detergent mixture is distinguished by the fact that the trichloroisocyanuric acid used is coated with a paraffin wax used in a concentration of from 1 to 10% by weight calculated on the weight of the acid.
Det har vist seg at parafinvokser er forlikelige med triklorisocyanursyre. Dessuten gjør disse det mulig, selv når de anvendes i relativt små mengder, å oppnå en god stabilisering av syren. Videre er de dispergerbare under vaskebetingelsene, det vil si i vandige medier ved temperaturer på 50-60°C. Paraffin waxes have been found to be compatible with trichloroisocyanuric acid. Moreover, these make it possible, even when used in relatively small amounts, to achieve a good stabilization of the acid. Furthermore, they are dispersible under washing conditions, that is to say in aqueous media at temperatures of 50-60°C.
Parafinvoksene består av en blanding av faste hydrocar-boner som har høy molekylvekt (f.eks. C^gH-^) , som har et smeltepunkt som er lavere enn 60°C og høyere enn 4 0°C, og som har en viskositet ved 100°C som er lavere enn 6 eps. De benyttes i en konsentrasjon av fra 1 til 10 vekt%, beregnet på triklorisocyanursyren, fortrinnsvis i en konsentrasjon iav fra 3 til 5 vekt%. Ved bruk av mer enn 5 vekt% kan det oppstå van-skeligheter ved utførelsen av overtrekkingsoperasjonen, og det vil være nødvendig å modifisere overtrekkingsbetingelsene for å oppnå et ønsket overtrekk. Anvendelse av mengder utover 10 vekt% gir ingen nevneverdig forbedring av lagringsstabiliteten av vaskemiddelblandingene, og bruk av mengder under 1 vekt% resulterer i ubetydelig stabilisering. The paraffin waxes consist of a mixture of solid hydrocarbons which have a high molecular weight (e.g. C^gH-^), which have a melting point lower than 60°C and higher than 40°C, and which have a viscosity at 100°C which is lower than 6 eps. They are used in a concentration of from 1 to 10% by weight, calculated on the trichloroisocyanuric acid, preferably in a concentration of from 3 to 5% by weight. If more than 5% by weight is used, difficulties may arise when carrying out the coating operation, and it will be necessary to modify the coating conditions in order to achieve a desired coating. Use of amounts in excess of 10% by weight does not provide any appreciable improvement in the storage stability of the detergent mixtures, and use of amounts below 1% by weight results in negligible stabilization.
Ved fremstillingen av vaskemiddelblandingene ifølge oppfinnelsen foretas først overtrekkingen av triklorisocyanursyren med parafinvoksene. Denne overtrekkingsoperasjon ut-føres i en hvilken som helst type industriell blander, såsom i en trommelblander, fortrinnsvis en blander som er utstyrt med en oppvarmningsinnretning. Det er likeledes mulig å benytte en roterende blander av betongblandertypen, i hvilken den smeltede voks sprøytes på syren mens denne holdes oppvarmet ved en temperatur på rundt 50°C. En slik temperatur muliggjør god -fordeling av parafinvoksen, som størkner ved avkjøling. In the preparation of the detergent mixtures according to the invention, the trichloroisocyanuric acid is first coated with the paraffin waxes. This coating operation is carried out in any type of industrial mixer, such as in a drum mixer, preferably a mixer equipped with a heating device. It is also possible to use a rotary mixer of the concrete mixer type, in which the melted wax is sprayed onto the acid while it is kept heated at a temperature of around 50°C. Such a temperature enables good distribution of the paraffin wax, which solidifies on cooling.
Den voksbelagte triklorisocyanursyre blandes så i en annen blander med de øvrige bestanddeler av vaskemiddelblandingen. The wax-coated trichloroisocyanuric acid is then mixed in another mixer with the other components of the detergent mixture.
Mengdene av de forskjellige bestanddeler som i tillegg til parafinet benyttes for fremstilling av de nye vaskemiddelblandinger ifølge oppfinnelsen, er i og for seg konvensjonelle. Det bløtgjørende middel valgt blant polyfosfater benyttes i en mengde av fra 25 til 60 vekt%, fortrinnsvis i en mengde av fra 40 til 50 vekt%, beregnet på vekten av blandingen. The quantities of the various components which, in addition to the paraffin, are used for the production of the new detergent mixtures according to the invention, are in and of themselves conventional. The softening agent selected from polyphosphates is used in an amount of from 25 to 60% by weight, preferably in an amount of from 40 to 50% by weight, calculated on the weight of the mixture.
Det alkaliserende middel valgt blant natriumsilicater benyttes i en mengde av fra 30 til 70 vekt%, fortrinnsvis i en mengde av fra 40 til 60 vekt%, beregnet på vekten av blandingen. Som i og for seg kjent kan natriumsilicat delvis erstattes med natriumcarbonat, natriumsulfat eller natriumhydroxyd. Det ikke-ioniske overflateaktive middel benyttes i en mengde av^fra 0,5 til 4 vekt%, fortrinnsvis i en mengde av fra 1 til 3 vekt%, beregnet på vekten av blandingen. Triklorisocyanursyren overtrukket med parafin^roksen benyttes i en mengde av fra 0,5 til 5 vekt%, fortrinnsvis i en mendge av fra 1 til 3 vekt%, beregnet på vekten av blandingen. The alkalizing agent selected from sodium silicates is used in an amount of from 30 to 70% by weight, preferably in an amount of from 40 to 60% by weight, calculated on the weight of the mixture. As is known in and of itself, sodium silicate can be partially replaced with sodium carbonate, sodium sulfate or sodium hydroxide. The nonionic surfactant is used in an amount of from 0.5 to 4% by weight, preferably in an amount of from 1 to 3% by weight, calculated on the weight of the mixture. The trichloroisocyanuric acid coated with paraffin wax is used in an amount of from 0.5 to 5% by weight, preferably in an amount of from 1 to 3% by weight, calculated on the weight of the mixture.
De følgende eksempler illustrerer oppfinnelsen. The following examples illustrate the invention.
Eksempel 1Example 1
Triklorisocyanursyre blir først stabilisert med parafinvoksen på følgende måte: Syren oppvarmes til en temperatur på 50°C og anbringes så i én roterende blander (drageringsapparat). Mens blanderen roterer, påsprøytes parafinvoks ovenfra ved hjelp av en sprøyte-pistol. Den benyttede temperatur muliggjør en god fordeling av voksen, som størkner ved avkjøling. Den benyttede parafinvoks har et smeltepunkt som er lavere enn 6 0°C og en viskositet ved 100°C som er mindre enn 6 eps. Forskjellige blan- Trichloroisocyanuric acid is first stabilized with paraffin wax in the following way: The acid is heated to a temperature of 50°C and then placed in a rotating mixer (coating apparatus). While the mixer is rotating, paraffin wax is sprayed on from above using a spray gun. The temperature used enables a good distribution of the wax, which solidifies on cooling. The paraffin wax used has a melting point that is lower than 60°C and a viscosity at 100°C that is less than 6 eps. Different mix-
dinger av syre og voks tilberedes ved at det benyttes varierende presentmengder polyethylenvoks. De således erholdte blandinger benyttes for fremstilling av vaskemiddelblandinger. products of acid and wax are prepared by using varying amounts of polyethylene wax. The mixtures thus obtained are used for the production of detergent mixtures.
Vaskemidler av følgende sammensetning fremstilles:Detergents of the following composition are produced:
- Natriumtripolyfosfat: 50 vektdeler.- Sodium tripolyphosphate: 50 parts by weight.
- Natriummetasilicat (vannfritt eller 5^0-hydrat): 50 vektdeler. - "Plurafac" RA 43 (ethoxylert ikke-ionisk overflateaktivt middel fremstilt av firmaet PCUK): 2 vektdeler, - Sodium metasilicate (anhydrous or 5^0-hydrate): 50 parts by weight. - "Plurafac" RA 43 (ethoxylated non-ionic surfactant produced by the company PCUK): 2 parts by weight,
- Triklorisocyanursyre overtrukket med parafinvoks:- Trichloroisocyanuric acid coated with paraffin wax:
2 vektdeler.2 parts by weight.
En forhåndsblanding av natriumtripolyfosfat med ikke-ionisk overflateaktivt middel blir først tilberedt i en blander av roterende type. Etter 20 minutter oppnås en homogen blanding. Metasilicatet blir så tilsatt blanderen,og etter 2 0 minutter tilsettes den overtrukkede triklorisocyanursyre. Hele blandingen blandes så i den roterende blander i 20 minutter. Mengden av klor i vaskemiddelblåndingen, bestemt jodometrisk, er da 1,65%. A premix of sodium tripolyphosphate with nonionic surfactant is first prepared in a rotary type mixer. After 20 minutes, a homogeneous mixture is obtained. The metasilicate is then added to the mixer, and after 20 minutes the coated trichloroisocyanuric acid is added. The whole mixture is then mixed in the rotary mixer for 20 minutes. The amount of chlorine in the detergent mixture, determined iodometrically, is then 1.65%.
Den på denne måte fremstilte vaskemiddelblanding anbringes i plastposer sont lukkes med en lukkeinnretning som ikke gir hermetisk lukking. Posene lagres i en ovn ved de følgende re-gulerte betingelser: The detergent mixture produced in this way is placed in plastic bags and closed with a closing device that does not provide a hermetic seal. The bags are stored in an oven under the following regulated conditions:
- Temperatur 4(Pc,- Temperature 4(Pc,
- Relativ fuktighet 80%.- Relative humidity 80%.
Etter mellom 1 og 3 måneders lagring taes det ut prøver, og restklorinnholdet bestemmes jodometrisk. After between 1 and 3 months of storage, samples are taken, and the residual chlorine content is determined iodometrically.
Tabell 1 viser resultatene oppnådd etter 50 dagers lagring for vaskemiddelblandinger fremstilt ut fra vannfritt natriummetasilicat og ut fra triklorisocyanursyre overtrukket med parafinvoks benyttet i varierende prosentmengder (på vekt-basis). Restklormengdene er uttrykt i prosent av det opprinne-lige klorinnhold. Table 1 shows the results obtained after 50 days of storage for detergent mixtures prepared from anhydrous sodium metasilicate and from trichloroisocyanuric acid coated with paraffin wax used in varying percentage amounts (on a weight basis). The residual chlorine amounts are expressed as a percentage of the original chlorine content.
Eksempel 2 Example 2
Eksempel 1 gjentas, bortsett fra at det for fremstilling av vaskemiddelblandingene benyttes natriummetasilicat-pentahyd- rat istedenfor det vannfrie metasilicat som ble benyttet i Eksempel 1. Resultatene er oppsummert i Tabell 2. Example 1 is repeated, except that for the preparation of the detergent mixtures, sodium metasilicate pentahydrate is used instead of the anhydrous metasilicate that was used in Example 1. The results are summarized in Table 2.
Eksempel 3 Example 3
Eksempler 1 og 2 gjentas, idet det benyttes parafinvoks med smeltepunkt 4 0-42°C. Prøver tas ut etter 80 dagers lagring. Tabell 3 viser de resultater som ble oppnådd for vaskemiddelblandinger fremstilt enten ved anvendelse av vannfritt natriummetasilicat eller ved anvendelse av natriummetasilicat-péntahydrat. Examples 1 and 2 are repeated, using paraffin wax with melting point 4 0-42°C. Samples are taken out after 80 days of storage. Table 3 shows the results obtained for detergent compositions prepared either using anhydrous sodium metasilicate or using sodium metasilicate pentahydrate.
