Description
Vaske- og rengjøringsmidler. Washing and cleaning agents.
Foreliggende oppfinnelse vedrører vaske- og rengjøringsmidler og tar sikte på å tilveiebringe et slikt middel som egner seg bedre til flere forskjellige formål enn de hittil kjente midler. The present invention relates to washing and cleaning agents and aims to provide such an agent which is better suited for several different purposes than the previously known agents.
Til mange formål er det hensiktsmessig at rengjøringsmidler i vannoppløsning har en pH-verdi som ligger ved eller noe over nøytralpunktet, f. eks. 7—9. Dette er f. eks. tilfelle ved midler til vasking av servise, da fettstoffer i huden, lecitiner m. m. vaskes ut ved høyere pH-verdier, slik at huden blir tørr. Et middel med lavere pH-verdi er altså skånsommere for hendene. Også ved vas-ning av malte flater er en lav pH-verdi ønskelig, da sterkere alkaliske midler kan virke nedbrytende på stoffene i fargen. Et annet anvendelsesformål, hvor en lav pH-verdi er ønskelig, er ved vaskning av plagg av ull og andre proteinholdige fibre som vaskes ved lav temperatur (vanligvis høyst 40° C), dels fordi slike fibre er følsomme for høyere alkalitet og dels fordi fargestoffene kan angripes ved høyere pH-verdi. Det samme gjelder ofte for farger i kulørte plagg av annet fiberslag enn det nevnte, som vanligvis vaskes ved en temperatur på mellom 40 og 60° C. For many purposes, it is appropriate that cleaning agents in water solution have a pH value that lies at or slightly above the neutral point, e.g. 7-9. This is e.g. case with agents for washing crockery, as fatty substances in the skin, lecithins etc. are washed out at higher pH values, so that the skin becomes dry. A product with a lower pH value is therefore gentler on the hands. Also when washing painted surfaces, a low pH value is desirable, as stronger alkaline agents can have a degrading effect on the substances in the colour. Another purpose of use, where a low pH value is desirable, is when washing garments made of wool and other protein-containing fibers that are washed at a low temperature (usually no more than 40° C), partly because such fibers are sensitive to higher alkalinity and partly because the dyes can be attacked at a higher pH value. The same often applies to colors in colored garments of other fiber types than those mentioned, which are usually washed at a temperature of between 40 and 60°C.
Når det derimot er spørsmål om høy-temperaturvasking (vasking av bomulls- og linvarer og liknende)., er det ønskelig med en høyere pH-verdi. Dels er cellulosefib-rene mindre følsomme for alkali, dels er den høyere pH-verdi fordelaktig for vaske-virkningen. Smusset utgjøres nemlig for en stor dels vedkommende av fettsyrer, hvori er innfanget faste partikler (sot og støv av forskjellige slag). Vaskingen består i første omgang i en forsåpning av fett-syrene, hvorved den faste smuss også løs-gjøres. Forsåpningen skjer best ved en pH-verdi på 9,5 eller høyere, men da cellulose-fibrene ikke er helt ufølsomme overfor alkali, bruker man vanligvis ikke å overskride pH 11. When, on the other hand, there is a question of high-temperature washing (washing cotton and linen items and the like), a higher pH value is desirable. Partly, the cellulose fibers are less sensitive to alkali, and partly the higher pH value is beneficial for the washing effect. The dirt is made up for a large part of fatty acids, in which solid particles (soot and dust of various kinds) are trapped. The washing initially consists of a saponification of the fatty acids, whereby the solid dirt is also loosened. The saponification takes place best at a pH value of 9.5 or higher, but as the cellulose fibers are not completely insensitive to alkali, it is not usually used to exceed pH 11.
Hensikten med foreliggende oppfinnelse er å fremstille et vaske- og rengjør-ingsmiddel som ved lavere temperatur, f. eks. opp til omkring 50 eller 60° C bibehol-der en pH-verdi innenfor området 7,5—9,5, særlig omkring 8,5, under i det minste en temmelig lang tidsperiode, men som etter noén tids påvirkning av høyere temperaturer (f. eks. 80—100° C) får en pH-verdi innenfor intervallet 9,5—11, særlig 10—10,5, hvilket oppnåes ved at magnesiumoksyd tilsettes til midlet. The purpose of the present invention is to produce a washing and cleaning agent which at a lower temperature, e.g. up to about 50 or 60° C maintains a pH value within the range 7.5-9.5, especially about 8.5, for at least a fairly long period of time, but as after some time of exposure to higher temperatures ( e.g. 80-100° C) gets a pH value within the range 9.5-11, especially 10-10.5, which is achieved by adding magnesium oxide to the agent.
Oppfinnelsen kan generelt sett anvendes ved slike vaske- og rengjøringsmidler der en aktiv ingrediens inneholder syntetiske overflate-aktive midler av anionaktiv eller kationaktiv type. Som eksempel på anionaktive midler, som kan anvendes i henhold til oppfinnelsen, kan nevnes alkyl-arylsulfonater, særlig alkylbenzensulfona-ter, i hvilke alkylgruppen inneholder 8—20 kullstoffer, f. eks. dodecylbenzensulfonater eller oktadecylbenzensulfonater; høyere alifatiske sulfater og sulfonater, i hvilke den alifatiske gruppe inneholder 8—20 kullstoffatomer, såsom laurylsulfat eller laurylsulfonat samt høyere fettsyreamider, hvori fettsyregruppen inneholder 8—20 kvelstoffatomer, såsom talgfettsyreamid. De nevnte sulfonater anvendes for det meste i form av alkalimetallsulfonater, særlig natriumsulfonater, skjønt tilsvarende salter av ammonium eller organiske baser, såsom etanolamin eller trietanolamin, også kan anvendes. Som kationaktive midler som kan anvendes ifølge oppfinnelsen, kan nevnes polyglykoleter av høyere alkoholer og polyglokolestrer av høyere fettsyrer, hvori alkoholgruppen henh. fettsyregruppen inneholder 8—20 kullstoffatomer og som inneholder 10—50 etylenoksydenheter pr. molekyl. Et sort antall både anionaktive og kationaktive syntetiske overflate-aktive midler av den foran nevnte og andre typer samt fremgangsmåter ved deres fremstil-ling er kjent og beskrevet i litteraturen. Det må fremheves at hva angår foreliggende oppfinnelse, er typen av det overflateaktive middel i og for seg uten betydning, da den for oppfinnelsen karakteris-tiske pH-økning er uavhengig av det an-vendte overflateaktive middel. Det kan derfor anvendes et hvilket som helst anionaktivt eller kationaktivt syntetisk overflateaktivt middel. Det må dog fremheves at såper ikke kan anvendes, da de i og for seg gir en altfor høy pH-verdi. Mengden av det kationaktive eller anionaktive overflateaktive middel er vanligvis omkring 15 —50 % av vaskemidlets vekt, fortrinnsvis 15—25 % (beregnet av midlets tørrsub-stans). The invention can generally be used with such detergents and cleaning agents where an active ingredient contains synthetic surface-active agents of the anion-active or cation-active type. As examples of anionic agents which can be used according to the invention, mention may be made of alkyl aryl sulphonates, particularly alkylbenzene sulphonates, in which the alkyl group contains 8-20 carbons, e.g. dodecylbenzenesulfonates or octadecylbenzenesulfonates; higher aliphatic sulfates and sulfonates, in which the aliphatic group contains 8-20 carbon atoms, such as lauryl sulfate or lauryl sulfonate, and higher fatty acid amides, in which the fatty acid group contains 8-20 nitrogen atoms, such as tallow fatty acid amide. The mentioned sulphonates are mostly used in the form of alkali metal sulphonates, particularly sodium sulphonates, although corresponding salts of ammonium or organic bases, such as ethanolamine or triethanolamine, can also be used. As cationic active agents which can be used according to the invention, mention may be made of polyglycol ethers of higher alcohols and polyglycol esters of higher fatty acids, in which the alcohol group acc. the fatty acid group contains 8-20 carbon atoms and which contain 10-50 ethylene oxide units per molecule. A large number of both anion-active and cation-active synthetic surface-active agents of the aforementioned and other types as well as methods for their production are known and described in the literature. It must be emphasized that with regard to the present invention, the type of surfactant in and of itself is of no importance, as the pH increase characteristic of the invention is independent of the surfactant used. Any anion-active or cation-active synthetic surfactant can therefore be used. However, it must be emphasized that soaps cannot be used, as they in and of themselves give a far too high pH value. The amount of the cationic or anionic surfactant is usually around 15-50% of the weight of the detergent, preferably 15-25% (calculated from the agent's dry substance).
Foruten det overflateaktive middel inneholder vaske- og rengjøringsmidler av de her beskrevne typer et alkalifosfat som har til oppgave å forbedre vaskeeffekten. Som slike fosfater kan nevnes natrium- eller kaliumsalter av orto-, meta-, poly- og pyro-fosforsyrer, f. eks. natriumheksametafosfat, natriumpyrofosfat, natriumtrifosfat, dina-triumortofosfat m. m. Fosfatmengden ut-gjør i alminnelighet 25—50 vektprosent av vaskemidlets tørrsubstans. In addition to the surface-active agent, washing and cleaning agents of the types described here contain an alkali phosphate whose task is to improve the washing effect. Examples of such phosphates include sodium or potassium salts of ortho-, meta-, poly- and pyro-phosphoric acids, e.g. sodium hexametaphosphate, sodium pyrophosphate, sodium triphosphate, disodium orthophosphate, etc. The amount of phosphate generally accounts for 25-50% by weight of the detergent's dry substance.
I henhold til oppfinnelsen er man kommet frem til at et vaskemiddel av foran nevnte type som inneholder et kationaktivt eller anionaktivt overflateaktivt stoff og et fosfat, og som er slik sammensatt at dets pH-verdi som ved oppløsning i vann av romtemperatur ligger innenfor området 7,5—9,5, kan bibringes den egenskap at det ved opphetning (f. eks. til 80—100° C) av oppløsningen raskt får en pH-verdi på 9,5 In accordance with the invention, it has been concluded that a detergent of the aforementioned type which contains a cationically active or anionic surfactant and a phosphate, and which is composed in such a way that its pH value which, when dissolved in water at room temperature, lies within the range 7, 5-9.5, can be given the property that when heated (e.g. to 80-100° C) the solution quickly acquires a pH value of 9.5
—11 uten at noen vesentlig eller i hvert fall bare en langsom pH-økning skjer ved romtemperatur eller noe høyere temperatur (f. eks. opp til 60° C), hvis blandingen tilsettes magnesiumoksyd. Dette reagerer ved opphetning med alkalifosfatet under dannelse av magnesiumfosfat som er mindre dissosi- —11 without any significant or at least only a slow pH increase occurring at room temperature or a slightly higher temperature (e.g. up to 60° C), if magnesium oxide is added to the mixture. This reacts on heating with the alkali phosphate to form magnesium phosphate, which is less dissoci-
ert enn alkalifosfatet og alkali, hvorved pH-verdien vil stige. Da denne reaksjon ved lavere temperatur bare skjer langsomt, vil bare en langsom pH-økning opptre ved romtemperatur. Mengden av magnesiumoksyd kan være 1—10 vektprosent av det ferdige vaskemiddels tørrsubstans. pea than the alkali phosphate and alkali, whereby the pH value will rise. As this reaction only happens slowly at lower temperatures, only a slow pH increase will occur at room temperature. The amount of magnesium oxide can be 1-10 percent by weight of the dry substance of the finished detergent.
Man er også kommet frem til at den ønskede effekt kan forbedres med hensyn til pH-verdiens konstans ved lavere temperatur på to forskjellige måter. Den ene fremgangsmåte består i å tilsette magnesiumoksydet et alkalibikarbonat som, over-raskende nok, vesentlig nedsetter pH-øk-ningen ved lav temperatur, men hindrer ikke den ønskede pH-økning i å finne sted ved høyere temperatur. Mengden av bikarbonat kan derved være 5—20 ganger mengden av magnesiumoksyd, eller 5—40 % av det ferdige vaskemiddels vekt. It has also been concluded that the desired effect can be improved with regard to the constancy of the pH value at a lower temperature in two different ways. One method consists in adding an alkali bicarbonate to the magnesium oxide which, surprisingly enough, significantly reduces the pH increase at low temperature, but does not prevent the desired pH increase from taking place at a higher temperature. The amount of bicarbonate can thereby be 5-20 times the amount of magnesium oxide, or 5-40% of the weight of the finished detergent.
Den annen måte består i å innblande magnesiumoksydet i form av et pulver, hvis enkelte partikler er overtrukket med et stoff som smelter og oppløses i vaskeoppløs-ningen ved ca. 50—60° C, hvorved magnesiumoksydet forblir uvirksomt eller «skjult» ved lavere temperatur, men ved tempera-turstigning over overtrekkstoffets smeltepunkt vil frigjøres og tilveiebringe den ønskede pH-økning. Som slike stoffer kan i og for seg anvendes ethvert stoff med egnet smeltepunkt, f. eks. parafin. Det foretrekkes imidlertid å anvende et slikt stoff som er til fordel for vaskingen, da petroleum i virkeligheten utgjør en belastning for vaskemidlet. Derfor foretrekkes der høyere fettalkoholer med smeltepunkter innenfor det angitte intervall, f. eks. cetylalkohol eller stearylalkohol, som etter smelting og oppløsning i vaskemiddeloppløsningen får en viss smussdispergerende virkning. Andre stoffer med liknende virkning er slike etylenoksydanlagringsprodukter av liknende fettalkoholer som inneholder bare et fåtall, f. eks. 1—4 etylenoksydmolekyler, pr. molekyl fettalkohol. Det overtrukne magnesiumoksydpulver fremstilles hensiktsmessig ved at magnesiumoksydpulver blan-des med det stoff som anvendes som overtrekkmateriale, f. eks. cetylalkohol i smeltet tilstand, hvorpå blandingen spres i kold luft slik at det smeltede overtrekkmateriale stivner og danner en hinne på hver enkelt magnesiumoksydpartikkel. Forholdet mellom begge stoffer kan avpasses slik at det overtrukkede pulver inneholder 25—75 % MgO og 75—25 % av overtrekksmaterialet. Fortrinnsvis er sammensetningen 40—60 % MgO og 60—40 % av overtrekkssubstansen. Magnesiumoksydet kan også under samti-dig anvendelse av bikarbonat brukes i form av et slikt overtrukket magnesiumoksyd, ennskjønt overtrekkets betydning i dette tilfelle er mindre. The second method consists in mixing in the magnesium oxide in the form of a powder, the individual particles of which are coated with a substance that melts and dissolves in the washing solution at approx. 50-60° C, whereby the magnesium oxide remains inactive or "hidden" at a lower temperature, but when the temperature rises above the coating material's melting point, it will be released and provide the desired pH increase. As such substances, any substance with a suitable melting point can be used in and of itself, e.g. kerosene. However, it is preferable to use such a substance which is beneficial for washing, as petroleum in reality constitutes a strain on the detergent. Therefore, higher fatty alcohols with melting points within the specified interval are preferred, e.g. cetyl alcohol or stearyl alcohol, which, after melting and dissolving in the detergent solution, has a certain dirt-dispersing effect. Other substances with a similar effect are such ethylene oxide storage products of similar fatty alcohols which contain only a few, e.g. 1-4 ethylene oxide molecules, per fatty alcohol molecule. The coated magnesium oxide powder is suitably prepared by mixing magnesium oxide powder with the substance used as coating material, e.g. cetyl alcohol in a molten state, after which the mixture is dispersed in cold air so that the molten coating material hardens and forms a film on each individual magnesium oxide particle. The ratio between both substances can be adjusted so that the coated powder contains 25-75% MgO and 75-25% of the coating material. Preferably, the composition is 40-60% MgO and 60-40% of the coating substance. The magnesium oxide can also be used with the simultaneous use of bicarbonate in the form of such a coated magnesium oxide, although the importance of the coating in this case is less.
For å oppnå den ved lavere temperatur ønskede, lavere pH-verdi, kan det ofte være ønskelig å blande inn surt reagerende stoffer. Det er kjent med dette for øye å anvende som fosfat surt natriumpyrofosfat (NauH^Pi» Ot), hvilket også kan anvendes i dette tilfelle. Dette stoff har imidlertid en relativt sterk bremsevirkning som kan mot-virke den ønskede pH-stigning ved høyere temperatur, slik at den ikke blir så kraftig som det ofte kan være ønskelig. Det kan derfor i visse tilfeller være mere fordelaktig å anvende en mindre mengde av en sterk syre, såsom svovelsyre, for å få en lav pH-verdi. Mengden av syre kan da utgjøre 0— 10 % av den ferdige blandingens vekt. In order to achieve the desired, lower pH value at a lower temperature, it may often be desirable to mix in acid-reactive substances. It is known for this purpose to use as phosphate acidic sodium pyrophosphate (NauH^Pi»Ot), which can also be used in this case. However, this substance has a relatively strong braking effect which can counteract the desired pH rise at a higher temperature, so that it does not become as strong as is often desirable. It can therefore in certain cases be more advantageous to use a smaller amount of a strong acid, such as sulfuric acid, in order to obtain a low pH value. The amount of acid can then amount to 0-10% of the weight of the finished mixture.
Foruten de ovenfor nevnte tilsetninger kan vaskemidlet i henhold til oppfinnelsen også inneholde slike stoffer som vanligvis brukes i vaskemidler av denne type. Således inneholder midlet vanligvis et høymole-kylært stoff, såsom en celluloseeter, særlig natriumsaltet av karboksymetylcellulose eller polyvinylpyrrolidon, f. eks. i en mengde av 0,5—2 % av den ferdige blandings vekt. Andre ofte forekommende tilsetninger er silikater, f. eks. vannglass (2—7 %), perborat (5—20 %) eller andre blekemidler, samt fluorescerende farvestoffer (såkalte optiske hvitemidler: 0,01—0,1%). Andre tilsetninger kan selvfølgelig også forekom-me innenfor rammen for oppfinnelsen. Det er imidlertid klart at man ikke innblander større mengder av stoffer som allerede ved lav temperatur har tendens til å gi høye pH-verdier, likesom heller ikke stoffer som kan forstyrre den ved høyere temperatur ønskede reaksjon. In addition to the above-mentioned additives, the detergent according to the invention can also contain such substances which are usually used in detergents of this type. Thus, the agent usually contains a high-molecular substance, such as a cellulose ether, in particular the sodium salt of carboxymethylcellulose or polyvinylpyrrolidone, e.g. in an amount of 0.5-2% of the weight of the finished mixture. Other frequently occurring additives are silicates, e.g. water glass (2-7%), perborate (5-20%) or other bleaching agents, as well as fluorescent dyes (so-called optical whitening agents: 0.01-0.1%). Other additions can of course also occur within the scope of the invention. It is clear, however, that one does not mix in large quantities of substances which tend to give high pH values already at low temperatures, as well as substances which can interfere with the desired reaction at higher temperatures.
Midlet i henhold til oppfinnelsen fremstilles fortrinnsvis i form av et pulver, skjønt det også kan fremstilles i væske-form. Ved anvendelse til vasking oppløses 1— 10 g av midlet (regnet som tørt mate-riale) i 1 liter vann. The agent according to the invention is preferably produced in the form of a powder, although it can also be produced in liquid form. When used for washing, dissolve 1-10 g of the agent (calculated as dry material) in 1 liter of water.
Oppfinnelsen belyses nærmere ved følgende utførelseseksempler. The invention is explained in more detail by the following examples.
Eksempel 1: Example 1:
40 kg 98 %'s svovelsyre tilsettes til 400 1 vann under kjøling. Til oppløsningen tilsettes under omrøring 400 kg natriumtrifosfat under omrøring, hvorunder tempera-turen holdes under 70 <0> C. I oppløsningen innføres deretter 350 kg natriumsulfat. Derpå tilblandes 850 kg av en vannholdig pasta inneholdende 33 % overflateaktivt materi-ale som består av 5 deler natriumdodecyl- 40 kg of 98% sulfuric acid is added to 400 1 of water while cooling. 400 kg of sodium triphosphate are added to the solution while stirring, during which the temperature is kept below 70 <0> C. 350 kg of sodium sulphate are then introduced into the solution. Then 850 kg of an aqueous paste containing 33% surface-active material consisting of 5 parts sodium dodecyl-
benzensulfonat og 2 deler natrium-cetyl-alkoholsulfat, hvilken pasta først tilsettes 20 kg teknisk natrium-karboksymetylcellulose (67 % NaCMC, resten biproduktsal-ter og vann), 14 kg 40 %'s vannoppløsning av etylendiamintetraeddiksyre og 0,76 g av et optisk hvitemiddel bestående av 4,4'-bis-2,4-diaminotriazinylamino .-stilben-2,2'-disulfonsyre. Den således frembragte oppslamming spre-tørkes til pulver. benzene sulphonate and 2 parts sodium cetyl alcohol sulphate, to which paste is first added 20 kg of technical sodium carboxymethyl cellulose (67% NaCMC, the rest by-product salts and water), 14 kg of a 40% aqueous solution of ethylenediaminetetraacetic acid and 0.76 g of an optical whitening agent consisting of 4,4'-bis-2,4-diaminotriazinylamino .-stilbene-2,2'-disulfonic acid. The resulting slurry is spread-dried to powder.
250 kg av pulveret blandet med 67 kg natriumperborat og 36 kg «skjult» magnesiumoksydpulver bestående av 55 % magnesiumoksyd og 45 % cetylalkohol. Dette «skjulte» magnesiumoksydpulver fåes ved utrøring av magnesiumoksydpulver i smeltet cetylalkohol og spredning av blandingen i kald luft. 250 kg of the powder mixed with 67 kg of sodium perborate and 36 kg of "hidden" magnesium oxide powder consisting of 55% magnesium oxide and 45% cetyl alcohol. This "hidden" magnesium oxide powder is obtained by stirring magnesium oxide powder in molten cetyl alcohol and spreading the mixture in cold air.
I en vaskemaskin ble der innført 12 kg vasketøy sammen med 50 1 vann og 210 g av pulveret, fremstilt som forklart ovenfor. Blandingens PH-verdi var ved 25° C 8,2. Maskinens innhold ble i løpet av 30 min. oppvarmet til 85° C, hvorved pH-verdien steg til 9,2. Etter 15 min. ved 85° C var pH-verdien 9,8. 12 kg of laundry were introduced into a washing machine together with 50 l of water and 210 g of the powder, prepared as explained above. The mixture's PH value at 25° C was 8.2. The machine's contents were within 30 min. heated to 85° C, whereby the pH value rose to 9.2. After 15 min. at 85° C the pH value was 9.8.
Ved et annet forsøk med vasking ved 40° C holdt pH-verdien seg i det vensent-lige konstant. In another attempt with washing at 40° C, the pH remained essentially constant.
Eksempel. 2: Example. 2:
7,05 g av et ifølge første avsnitt i eksempel 1 fremstilt vaskemiddel ble blandet med 0,95 g natriumperborat og 0,72 g «skjult» magnesiumoksyd (inneholdende 40% MgO og 60% cetylalkohol). Blandingen ble oppløst i 2 1 vann og oppløsningen ble kokt i en kjele sammen med 200 g sterkt fettsyre-forurenset vasketøy. Oppløsningens pH-verdi var til å begynne med 8,2 etter oppvarming til 100 <0> C (10 min.) 9,2 og etter 15 min. ved 100 <0> C 9,4. 7.05 g of a detergent prepared according to the first paragraph in example 1 was mixed with 0.95 g of sodium perborate and 0.72 g of "hidden" magnesium oxide (containing 40% MgO and 60% cetyl alcohol). The mixture was dissolved in 2 l of water and the solution was boiled in a kettle together with 200 g of heavily fatty acid-contaminated laundry. The pH value of the solution was initially 8.2 after heating to 100 <0> C (10 min.) 9.2 and after 15 min. at 100 <0> C 9.4.
I et annet forsøk ble den samme blan-ding anvendt men uten magnesiumoksydet. Da var pH-verdien til å begynne med 8,2 etter opphetning til 100 <0> C (10 min.) 8,1, og etter 15 min. ved 100° C 8,1. In another experiment, the same mixture was used but without the magnesium oxide. Then the pH value was initially 8.2 after heating to 100 <0> C (10 min.) 8.1, and after 15 min. at 100° C 8.1.
I de følgende eksempler angis sammensetningen av et antall ytterligere vaskemidler ifølge oppfinnelsen. Disse midler kan stort sett fremstilles på samme måte som midlet ifølge eksempel 1, dvs. slik at en oppslamming i vann fremstilles av alle bestandstoffer bortsett fra perborat og magnesiumoksydet, samt eventuelt bikarbonat, hvoretter denne oppslamming spre-tørkes slik at der fåes et pulver, hvortil der derpå tilblandes perborat, magnesiumoksyd og eventuelt bikarbonat. Sammensetningen er angitt i vektprosent. Med «optisk hvitemiddel» er å forstå det i eksempel 1 angitte optiske hvitemiddel. De angitte pH-verdier er bestemt i oppløsninger inneholdende 4 g/liter av midler. In the following examples, the composition of a number of additional detergents according to the invention is indicated. These agents can be largely prepared in the same way as the agent according to example 1, i.e. so that a slurry in water is prepared from all ingredients except perborate and the magnesium oxide, as well as possibly bicarbonate, after which this slurry is spread-dried so that a powder is obtained, to which perborate, magnesium oxide and possibly bicarbonate are then mixed. The composition is stated in weight percent. "Optical brightener" means the optical brightener specified in example 1. The indicated pH values are determined in solutions containing 4 g/litre of agents.
Dette middel har ved oppløsning i vann av romtemperatur en pH-verdi på 8,7. Etter en halv time ved 25° C er pH-verdien 8,9, etter en halv time ved 50° C 9,5 og etter en halv time ved 100° C 10,0. When dissolved in water at room temperature, this agent has a pH value of 8.7. After half an hour at 25° C the pH value is 8.9, after half an hour at 50° C 9.5 and after half an hour at 100° C 10.0.
Eksempel 4: Example 4:
Dette middel har ved oppløsning i vann av, romtemperatur og opp til 60° C en pH-verdi på ca. 9,0. Etter en halv times kokning av oppløsningen stiger dens pH-verdi til 10,0. When dissolved in water at room temperature and up to 60°C, this agent has a pH value of approx. 9.0. After half an hour of boiling the solution, its pH value rises to 10.0.
Eksempel 5: Example 5:
Dette middel viser ved oppløsning i vann av 25 ° C en pH-verdi på 9,3. Etter oppvarming til 100° C stiger pH-verdien til 10,3. When dissolved in water at 25 °C, this agent shows a pH value of 9.3. After heating to 100° C, the pH value rises to 10.3.
Eksempel. 6: Example. 6:
Dette middel har ved oppløsning i vann av 250° C en pH-verdi på 8,5 og etter opphetning til 100° C 10,0. When dissolved in water at 250° C, this agent has a pH value of 8.5 and after heating to 100° C 10.0.
Eksempel 7: Example 7:
Dette middel har ved oppløsning i vann av 25° C en pH-verdi på 9,4 og etter opphetning til 100° C 10,5. When dissolved in water at 25°C, this agent has a pH value of 9.4 and after heating to 100°C 10.5.
