Description
Fremgangsmåte for fremstilling av blekende vaskemiddeltabletter. Method for the production of bleaching detergent tablets.
Nærværende oppfinnelse vedrører en fremgangsmåte for fremstilling av vaskemiddeltabletter som inneholder alkalimetalltripolyfosfat av både form I og form II, et anionisk rensemiddel og et ikke-ionisk rensemiddel. The present invention relates to a method for producing detergent tablets containing alkali metal tripolyphosphate of both form I and form II, an anionic detergent and a non-ionic detergent.
Vaskemiddeltabletter er blitt mer og mer polulære i de siste Detergent tablets have become more and more popular in recent years
år, forst og fremst på grunn av at de er behagelige å anvende. years, primarily because they are comfortable to use.
Et problem som det imidlertid har vært vanskelig å lose, er å regulere opplosningshastigheten for tabletten i vaskeopplosningen. Nærværende oppfinnelse fremskaffer en forbedret rensemiddelblanding for anvendelse i vasketabletter, fra hvilke disse lett kan formes til tabletter som vil lose seg opp i forutbestemt hastighet i vaskeoppldsningen og som har fremragende vaskeegenskaper. One problem that has been difficult to solve, however, is regulating the dissolution rate of the tablet in the washing solution. The present invention provides an improved detergent mixture for use in washing tablets, from which these can be easily formed into tablets which will dissolve at a predetermined rate in the washing solution and which have excellent washing properties.
Det er kjent at alkalimetallpolyfosfåter eksisterer i to former av hvilke en hydratiserer relativt hurtig, er tungt opploselig og dannes ved hoye temperaturer (såkalt form I) og den andre som hydratiserer meget langsomt er lett opploselig og dannes ved lave temperaturer (såkalt form II). It is known that alkali metal polyphosphates exist in two forms, one of which hydrates relatively quickly, is poorly soluble and is formed at high temperatures (so-called form I) and the other, which hydrates very slowly, is easily soluble and is formed at low temperatures (so-called form II).
Oppfinnelsen angir en fremgangsmåte for fremstilling av en rensemiddelblanding for dannelse av vasketabletter, som omfatter varmetorring av en heterogen blanding av (i) 22 - 70$ av en blanding som består av 1 del av et alkalimetallpolyfosfat som har lavt innhold av form I (eller hdyt innhold av form II) og 0,3-1 del anionisk syntetisk rensemiddel eller såpe, til-blanding av (ii) 1 - 12$ ikke-ionisk syntetisk rensemiddel og (iii) 18 - 77% av alkalimetallpolyfosfat med hoyt innhold av form I. (Alle deler og forhold er etter vekt). Oppfinnelsen omfatter også fremstilling av de forbedrede vasketabletter som gjor bruk av blandingene. The invention provides a process for the preparation of a detergent mixture for the formation of detergent tablets, which comprises heat drying a heterogeneous mixture of (i) 22 - 70$ of a mixture consisting of 1 part of an alkali metal polyphosphate having a low content of form I (or hdyt content of form II) and 0.3-1 part anionic synthetic detergent or soap, addition of (ii) 1 - 12% nonionic synthetic detergent and (iii) 18 - 77% of alkali metal polyphosphate with a high content of form I .(All parts and ratios are by weight). The invention also includes the manufacture of the improved washing tablets that make use of the mixtures.
Fremgangsmåten for fremstilling av vaskemiddeltabletter ifolge oppfinnelsen karakteriseres ved at det The method for producing detergent tablets according to the invention is characterized by the fact that
(i) fremstilles en oppslemning som består av 1 vektdel av et alkalimetallpolyfosfat som har et lavt innhold av form I og fra 0,3 til 1 vektdeler av et anionisk rensemiddel, hvoretter (ii) denne oppslemning varmetorres på kjent måte til en partikkelformet homogen blanding, og (iii) denne blanding blandes med et ikke-ionisk rensemiddel og et alkalimetallpolyfosfat som har hoyt innhold av form I, slik at det oppnås en vaskemiddelblanding som inneholder 22 - 70 vekt$ av den varmetorrede blanding, 1-12 vekt# av det ikke-ioniske rensemiddel og 18 - 77 vekt# av alkalimetallpolyfosfatet (i) a slurry is prepared which consists of 1 part by weight of an alkali metal polyphosphate having a low content of form I and from 0.3 to 1 part by weight of an anionic cleaning agent, after which (ii) this slurry is heat-dried in a known manner to a particulate homogeneous mixture , and (iii) this mixture is mixed with a non-ionic detergent and an alkali metal polyphosphate having a high content of Form I, so that a detergent mixture is obtained which contains 22-70 wt% of the heat-dried mixture, 1-12 wt# of the non-ionic detergent and 18-77 wt# of the alkali metal polyphosphate
som har hoyt innhold av form I og which has a high content of form I and
(iv) påfore blandingen som er dannet ved trinnene (i), (ii) og (iii) på kjent måte som et ytre overtrekk rundt en kjerne som består av en fast, vannopploselig, blekende blanding. (iv) applying the composition formed by steps (i), (ii) and (iii) in known manner as an outer coating around a core consisting of a solid water-soluble bleaching composition.
Vaskemiddeltabletter som er fremstilt etter nærværende oppfinnelse og hvor den angitte rensemiddelblanding er påfort en kjerne som foran angitt, vil opplose seg i vaskeopplosningen for vasketoy i den onskede grad, ha en hårdhet eller styrke som gjor det mulig for dem å tåle paknings- og behandlingsbetingel-ser og ha utmerkede vaskeegenskaper for stoffer, f.eks. utmerket opploselighet og sterk smussfjerningseffektivitet i vaskeopp-losninger. Deres spesielle styrke oppnås uten å gripe til bindemidler eller ved overflatehydratisering, slik som ved på-sproytning av vann eller utsette dem for vanndamp. Detergent tablets which have been produced according to the present invention and where the indicated cleaning agent mixture has been applied to a core as indicated above, will dissolve in the washing solution for laundry to the desired extent, have a hardness or strength which enables them to withstand packaging and processing conditions looks and has excellent washing properties for fabrics, e.g. excellent solubility and strong soil removal efficiency in washing solutions. Their special strength is achieved without resorting to binders or by surface hydration, such as by spraying water or exposing them to water vapour.
Fortrinnsvis utgjor den varmetorrede andel eller komponent (i) ca. 35 - 60% av blandingen. Uttrykket "varmetorret" skal for-stås slik den generelt er gitt på vaskemiddelområdet, dvs. komponentene blandes sammen, vanligvis som en vandig oppslemning, og forstovningstorres i partikkelform eller trommeltorres og reduseres derpå til den onskede partikkelstorrelse. Preferably, the heat-dried portion or component (i) comprises approx. 35 - 60% of the mixture. The term "heat-dried" is to be understood as it is generally given in the detergent area, i.e. the components are mixed together, usually as an aqueous slurry, and spray-dried in particle form or drum-dried and then reduced to the desired particle size.
Polyfosfåtene som anvendes i den varmetorrede komponent (i) har lavt innhold av form (I) (eller hoyt innhold av form II) alkali-metallpolyfosfater, slik som natrium, kalium og litiumtripoly-fosfåter. Natriumtripolyfosfat foretrekkes, og skal for dette formål ha et lavt innhold av form I, dvs. inneholder mindre enn ca. 5% av form I Na^P^<O>-^Q. The polyphosphates used in the heat-dried component (i) have low content of form (I) (or high content of form II) alkali metal polyphosphates, such as sodium, potassium and lithium tripolyphosphates. Sodium tripolyphosphate is preferred, and for this purpose must have a low content of form I, i.e. contain less than approx. 5% of form I Na^P^<O>-^Q.
I den varmetorrede komponent kan mån bruke et eller flere av de velkjente anioniske syntetiske rensemidler eller såper. Særlig anvendelige anioniske syntetiske rensemidler er de vannopploselige salter av hoyere alifatisk og aromatisk sulfon- og svovel-syre, slik som natriumalkylbenzensulfonater og langkjedede alkylsulfater. Spesielle eksempler omfatter natrium oktyl-, nonyl-, dodecyl-, decyl- og tetradecylbenzensulfonater, natrium-diisopropylnaftalen-sulfat, langkjedede alkylsulfater, slik som natrium-lauryl- og stearylsulfater, mahogni og petroleumsulfo-nater, langkjedede alkyloksyetylen-sulfater, slik som natrium-eller kalium-laurylpolyoksyetylen-sulfat, natrium-laurylmono-oksyetylen-sulfat, natriumoktadecylpolyoksyetylen-sulfat og natriumcetylpolyoksyetylen-sulfat, langkjedede alkyl-aryloksy-etylensulfater, slik som ammonium, natrium eller kalium-nonyl-, oktyl- og tridecylfenol mono- og polyoksyetylensulfater, langkjedede alkyl-isetionater, slik som natriumolein-isetionat og natrium laurin-isetionat, lavere alkylsulfater og sulfonater, slik som natriumsulfatderivat av 2-etylheksanol-l, natrium-2-etyl-l-heksenylsulfonat, natrium-isooktylsulfonat og lavere alkylestere av alifatiske sulfokarboksyliske syrer, slik som natriumdiamylsulfosuccinat. In the heat-dried component, you can use one or more of the well-known anionic synthetic cleaning agents or soaps. Particularly useful anionic synthetic cleaning agents are the water-soluble salts of higher aliphatic and aromatic sulphonic and sulfuric acids, such as sodium alkylbenzene sulphonates and long-chain alkyl sulphates. Specific examples include sodium octyl, nonyl, dodecyl, decyl and tetradecylbenzene sulfonates, sodium diisopropylnaphthalene sulfate, long chain alkyl sulfates such as sodium lauryl and stearyl sulfates, mahogany and petroleum sulfonates, long chain alkyloxyethylene sulfates such as sodium -or potassium lauryl polyoxyethylene sulfate, sodium lauryl monooxyethylene sulfate, sodium octadecylpolyoxyethylene sulfate and sodium cetylpolyoxyethylene sulfate, long chain alkyl aryloxyethylene sulfates, such as ammonium, sodium or potassium nonyl, octyl and tridecylphenol mono and polyoxyethylene sulfates , long-chain alkyl isethionates, such as sodium olein isethionate and sodium lauric isethionate, lower alkyl sulfates and sulfonates, such as sodium sulfate derivative of 2-ethylhexanol-1, sodium 2-ethyl-1-hexenyl sulfonate, sodium isooctyl sulfonate and lower alkyl esters of aliphatic sulfocarboxylic acids, such as sodium diamyl sulfosuccinate.
Såper som kan anvendes omfatter de vannopploselige salter av myristin-, palmitin-, stearin-, behen-, olein-r, laurin-, abietin-, kaprin-, kapron-, ricinusolje- og linolensyrer, hydrert og dehydrerte abietinsyrer og overflateaktive hydrolyseprodukter av talg, kokosnottolje, bomullsfroolje, soyabonneolje, peanott-olje, sesam, linfroolje, olivenolje, maisolje, ricinusolje og Soaps that can be used include the water-soluble salts of myristic, palmitic, stearic, behenic, oleic, lauric, abietic, capric, caproic, castor oil and linolenic acids, hydrated and dehydrated abietic acids and surfactant hydrolysis products of tallow, coconut oil, cottonseed oil, soybean oil, peanut oil, sesame, linseed oil, olive oil, corn oil, castor oil and
lignende. the like.
I den varmetorrede blanding er vektforholdet mellom anionisk syntetisk rensemiddel og/eller såpe i polyfosfat fra ca. 0,3 : 1 til ca. 1 : 1, og det foretrukne forhold er innen området 0,<>>+ : 1 til 0,7 : 1. In the heat-dried mixture, the weight ratio between anionic synthetic detergent and/or soap in polyphosphate is from approx. 0.3 : 1 to approx. 1 : 1, and the preferred ratio is within the range of 0.<>>+ : 1 to 0.7 : 1.
Et ikke-ionisk syntetisk rensemiddel i en mengde på 1 - 12% kan også inkluderes i den varmetorrede komponent for å redusere klebning ved tablettlagning. I dette tilfelle får blandingen fortrinnsvis "herde" for den blandes med ytterligere polyfosfat og gjenværende ikke-ionisk rensemiddel. "Herding" krever hen-stand under svak omroring i en langsomt roterende blandeanord-ning for å tillate 'den varmetorrede andel å absorbere fuktig ikke-ionisk rensemiddel. Herding er vanligvis ikke nodvendig, hvis -en del av det ytterligere polyfosfat tilsettes umiddelbart, . slik at de fuktige partikler blir overtrukket med dette. A non-ionic synthetic detergent in an amount of 1-12% may also be included in the heat-dried component to reduce sticking during tableting. In this case, the mixture is preferably allowed to "cure" before it is mixed with additional polyphosphate and remaining non-ionic detergent. "Curing" requires standing under gentle agitation in a slowly rotating mixer to allow the heat-dried portion to absorb moist nonionic detergent. Curing is usually not necessary, if -part of the additional polyphosphate is added immediately, . so that the moist particles are coated with this.

Den foretrukne varmetorring er forstovning og den foretrukne partikkelstorrelse er overveiende ca. 30 til ca. 100 mesh, med ikke mer enn ca. 10% gjennom 200 mesh. Slike metoder gir en homogen blanding som er egnet for oppfinnelsens formål. desired conditions, such as an aqueous slurry and then heat-dried, such as e.g. by atomization into particle form or by drum drying followed by reduction of the product to the desired particle size, e.g. 16 mesh (US standard). The preferred heat drying is atomization and the preferred particle size is predominantly approx. 30 to approx. 100 mesh, with no more than approx. 10% through 200 mesh. Such methods provide a homogeneous mixture which is suitable for the purpose of the invention.
Rensemiddelblandingene inneholder fortrinnsvis som komponent (ii), ca. 3 - 9% i ikke-ionisk syntetisk rens-emiddel, som fortrinnsvis er en væske. Typiske eksempler på slike rensemidler omfatter etylenoksydkondensasjonsprodukter med alkylfenoler, slik som nonylfenol, oktylfenol og diamylfenol, som vanligvis inneholder 6-20 eller flere mol etylenoksyd. Andre eksempler omfatter estere av sukkeralkoholer, slik som sorbitan og manni-tan, polyetylenoksyestere av talgoljesyrer, etoksylerte alkan-oler, slik som etoksylerte laurylalkohol, etylenoksyd-fettsyre-kondensater og propylenglykol-etylenoksyd-kondensater. The cleaning agent mixtures preferably contain as component (ii), approx. 3 - 9% in non-ionic synthetic detergent, which is preferably a liquid. Typical examples of such cleaning agents include ethylene oxide condensation products with alkylphenols, such as nonylphenol, octylphenol and diamylphenol, which usually contain 6-20 or more moles of ethylene oxide. Other examples include esters of sugar alcohols, such as sorbitan and mannitan, polyethyleneoxy esters of tallow fatty acids, ethoxylated alkanols, such as ethoxylated lauryl alcohol, ethylene oxide fatty acid condensates and propylene glycol ethylene oxide condensates.

Den resulterende rensemiddelsammensetning kunne anvendes til å gi fremragende vasketabletter for klesvask. The resulting detergent composition could be used to provide excellent laundry detergent tablets.
Rensemiddelblandingene som er fremstilt ifolge oppfinnelsen kan anvendes til å fremstille vaskemiddeltabletter ved fremgangsmåter som er velkjent på området. Vaskemiddeltabletter for flere formål som inneholder en blekemiddelkjerne kan fremstilles ved fremgangsmåter beskrevet i norsk patent nr. 110 837. F.eks. komprimeres forst blekematerialet og overtrekkes derpå med vaskemiddelblandingen. Hvis onsket, kan overtrekket forformes i to separate halvparter, hver med et hulrom og blekemiddelet kan komprimeres til den onskede form og derpå avsettes i hulrommet som dannes i en halvpart av overtrekket og den annen halvpart av det forformede overtrekk kan derpå presses på toppen, og danner en ferdig blanding som' har en kjerne av blekemiddélet og et overtrekk som henger sammen med dette og fullstendig lukker det inn. En annen metode for å fremstille en tablett er å forme en halvpart av overtrekket med et hulrom, fylle hulrommet med bleke-pulver, putte resten av overtrekksmaterialet på toppen og derpå presse den totale masse til den onskede form. Når rensemiddelblandingen anvendes for å fremstille en tablett anvendelig for flere formål og med en blekekjerne, skal den være i det vesent-lige torr, dvs. den skal ikke inneholde mer enn ca. 2% fuktighet og flyktige stoffer. Blandingene kan også brukes til å fremstille enkle rensemiddeltabletter uten blekende kjerne, slik som beskrevet i eksemplene. The detergent mixtures produced according to the invention can be used to produce detergent tablets by methods that are well known in the field. Detergent tablets for several purposes which contain a bleach core can be produced by methods described in Norwegian patent no. 110 837. E.g. the bleaching material is first compressed and then coated with the detergent mixture. If desired, the cover can be preformed into two separate halves, each with a cavity and the bleach can be compressed into the desired shape and then deposited into the cavity formed in one half of the cover and the other half of the preformed cover can then be pressed on top, and forms a finished mixture which has a core of the bleaching agent and an overcoat which adheres to this and completely encloses it. Another method of producing a tablet is to form half of the coating with a cavity, fill the cavity with bleaching powder, put the rest of the coating material on top and then press the total mass into the desired shape. When the cleaning agent mixture is used to produce a tablet usable for several purposes and with a bleaching core, it must be essentially dry, i.e. it must not contain more than approx. 2% moisture and volatile substances. The mixtures can also be used to prepare simple detergent tablets without a bleaching core, as described in the examples.
