Abstract
Description
Oppfinnelsen angår et vandig, surt, fortykket middel for rengjøring av sanitæranlegg, f.eks. toalettskåler. The invention relates to an aqueous, acidic, thickened agent for cleaning sanitary facilities, e.g. toilet bowls.
Et av de største problemer med slike rengjøringsmid-ler er at de må være i stand til å fjerne steinavsetningene som avsettes på skålens overflate. Det er kjent å benytte for dette formål vandige midler som inneholder minst én syre, såsom saltsyre, fosforsyre, svovelsyre, eddiksyre eller fumar-syre. One of the biggest problems with such cleaning agents is that they must be able to remove the stone deposits that are deposited on the surface of the bowl. It is known to use for this purpose aqueous agents containing at least one acid, such as hydrochloric acid, phosphoric acid, sulfuric acid, acetic acid or fumaric acid.
Imidlertid er de midler som inneholder saltsyre, kor-rosive og farlige, og det foretrekkes å benytte svake syrer. However, the agents containing hydrochloric acid are corrosive and dangerous, and it is preferable to use weak acids.
Det er likeledes kjent å forbedre rengjøringsmidlenes evne til å hefte til de skrånende skålvegger ved å tilsette et fortykningsmiddel. Således tilsettes det ofte anioniske og/eller ikke-ioniske overflateaktive midler eller andre fortykningsmidler, såsom polyethoxylerte aminer eller cellulose-derivater, såsom carboxymethylcellulose. It is also known to improve the ability of the cleaning agents to adhere to the sloping bowl walls by adding a thickener. Thus, anionic and/or non-ionic surfactants or other thickeners, such as polyethoxylated amines or cellulose derivatives, such as carboxymethylcellulose, are often added.
Vanligvis nødvendiggjør disse fortykningsmidler an-vendelse av additiver for å kunne benyttes, f.eks. alkoholer for å oppløse carboxymethylcellulosen i vann. Generally, these thickeners require the use of additives in order to be used, e.g. alcohols to dissolve the carboxymethyl cellulose in water.
For sure, fortykkede midler som anvendes for rengjø-ring av sanitæranlegg, må pH-området velges slik at stabilite-ten av tilførte parfymer ikke forringes. pH-verdier som er lavere enn 1,5, medfører således en spaltning av bestanddelene av de fleste parfymer. For acidic, thickened agents used for cleaning sanitary facilities, the pH range must be chosen so that the stability of added perfumes is not impaired. pH values lower than 1.5 thus result in a breakdown of the components of most perfumes.
Viskositeten av slike rengjøringsmidler må dessuten velges slik at det oppnås en tilfredsstillende evne til å fjerne steinavsetninger og til å holde på parfymene som ønskes av brukerne. Imidlertid vil utilstrekkelig viskositet hindre en tilstrekkelig hefting av rengjøringsmidlet til veggene, hvilket reduserer den tid midlet befinner seg i kontakt med steinavsetningene. På den annen side vil en for høy viskositet hindre spredning av parfymen i luften som omgir toalettene eller hindre inntrengning i det stillestående vann i bunnen av toalettene. The viscosity of such cleaning agents must also be selected so that a satisfactory ability to remove stone deposits and to retain the perfumes desired by the users is achieved. However, insufficient viscosity will prevent sufficient adhesion of the cleaning agent to the walls, which reduces the time the agent is in contact with the stone deposits. On the other hand, too high a viscosity will prevent the spread of the perfume in the air surrounding the toilets or prevent penetration into the stagnant water at the bottom of the toilets.
Det er et siktemål med den foreliggende oppfinnelse å tilveiebringe et vandig, surt, fortykket sanitærrengjørings-middel som ikke inneholder noen sterk syre, men som er i besittelse av en tilfredsstillende evne til å fjerne steinavsetninger, og som dessuten har en viskositet som kan reguleres for derved å oppnå god vedhefting til skrånende vegger og samtidig spredning av parfymen i den omgivende atmosfære. Videre er det ønskelig at sanitærrengjøringsmidlet samtidig er klart og gjennomsiktig og er stabilt ved omgivelsenes temperatur og ved +40°C i flere måneder. It is an object of the present invention to provide an aqueous, acidic, thickened sanitary cleaning agent which does not contain any strong acid, but which possesses a satisfactory ability to remove stone deposits, and which also has a viscosity which can be regulated for thereby achieving good adhesion to sloping walls and at the same time spreading the perfume in the surrounding atmosphere. Furthermore, it is desirable that the sanitary cleaning agent is at the same time clear and transparent and is stable at the ambient temperature and at +40°C for several months.
Det er kjent fortykningssystemer som utgjøres av amidobetainer med formelen: There are known thickening systems which consist of amidobetaines with the formula:
hvor R er et alkyl- eller alkenylradikal inneholdende 9-17 carbonatomer, n er et helt tall fra 2 til 4, og y er 0 eller et helt tall fra 1 til 3, og salt av disse forbindelser, valgt blant alkalimetall- og jordalkalimetallsulfåtene. where R is an alkyl or alkenyl radical containing 9-17 carbon atoms, n is an integer from 2 to 4, and y is 0 or an integer from 1 to 3, and salt of these compounds, selected from the alkali metal and alkaline earth metal sulfates.
Slike fortykningssystemer er beskrevet i europeisk patentsøknad nr. 77 674 (Unilever). I denne publikasjon nevnes det at de betainer som ikke inneholder noen amidogruppe, ikke er i stand til å fortykke vandige midler. Det nevnes også at amidobetainene ikke lar seg fortykke med natriumklorid eller natriumbromid. Sluttelig henvises det til en publikasjon i navnet Lonza i henhold til hvilken et cocoamidobetain som inneholder natriumklorid, ikke lar seg fortykke ved tilsetning av et anionisk overflateaktivt middel. Such thickening systems are described in European patent application no. 77 674 (Unilever). In this publication it is mentioned that the betaines which contain no amido group are not able to thicken aqueous media. It is also mentioned that the amidobetaines cannot be thickened with sodium chloride or sodium bromide. Finally, reference is made to a publication in the name of Lonza according to which a cocoamidobetaine containing sodium chloride cannot be thickened by the addition of an anionic surfactant.
I europeisk patentsøknad nr. 56 595 (Wellcome Founda-tion) beskrives hårvaskemidler som inneholder et betain med formelen: European patent application no. 56 595 (Wellcome Foundation) describes hair washing agents containing a betaine with the formula:
og en organisk syre. and an organic acid.
Disse midler kan foreligge i form av geler, dersom de tilsettes et fortykningsmiddel som f.eks. et overflateaktivt middel, f.eks. ethoxylert nonylfenol, eller som f.eks. en polymer, f.eks. et cellulosederivat. These agents can be in the form of gels, if a thickening agent such as e.g. a surfactant, e.g. ethoxylated nonylphenol, or as e.g. a polymer, e.g. a cellulose derivative.
I norsk patentsøknad nr. 863666 beskrives for anven-delse som fortykningsmidler i sanitærrengjøringsmidler visse alkylbetainer med formelen: In Norwegian patent application no. 863666, certain alkyl betaines with the formula are described for use as thickeners in sanitary cleaning agents.
hvor Ri er en alkylkjede med 10-22 C-atomer, og R2 og R3 kan være etoksylerte eller propoksylerte kjeder, henholdsvis (CH2CH20)n og (CH2-CH2CH20)n, hvor n er 1-5. De etoksylerte og propoksylerte kjeder i disse forbindelser, er toverdige grup-per som er bundet til N-atomet gjennom deres oksygenatom, og som i den andre ende er bundet til et oksygenatom i en annen tilsvarende gruppe eller til et avsluttende H-atom. where Ri is an alkyl chain with 10-22 C atoms, and R2 and R3 can be ethoxylated or propoxylated chains, respectively (CH2CH20)n and (CH2-CH2CH20)n, where n is 1-5. The ethoxylated and propoxylated chains in these compounds are divalent groups which are bound to the N atom through their oxygen atom, and which at the other end are bound to an oxygen atom in another corresponding group or to a terminating H atom.
Det har nå overraskende vist seg at visse betainer ikke bare er i stand til å fortykke vandige blandinger av svak syre, i nærvær av alkalimetall- eller jordalkalimetallhaloge-nid, men også muliggjør dispergering av parfymer, som kan til-føres mot slutten av blandeoperasjonen, uten at det finner sted separasjon i to faser. Disse betainer gjør det dessuten mulig å oppnå klare og gjennomsiktige midler som er stabile over tid, ved romtemperatur og ved temperaturer inntil +40°C. It has now surprisingly been found that certain betaines are not only capable of thickening aqueous weak acid mixtures, in the presence of alkali metal or alkaline earth metal halide, but also enable the dispersion of perfumes, which can be added towards the end of the mixing operation, without separation into two phases taking place. These betaines also make it possible to obtain clear and transparent agents which are stable over time, at room temperature and at temperatures up to +40°C.
Med oppfinnelsen tilveiebringes det således et vandig, surt, fortykket middel for rengjøring av sanitæranlegg, inneholdende foruten vann 0,5-6 vekt% av minst én svak syre, 2-8 vekt% av minst ett betain og 0,2-10 vekt% av minst ett uorganisk salt valgt blant alkalimetall- og jordalkalimetall-klorider og -sulfater samt eventuelt vanlige tilsetninger som parfyme, bakteriedrepende middel og farvestoff. Sanitærrengjø-ringsmidlet er karakteristisk ved at betainet eller betainene er valgt blant betainer med de generelle formler: The invention thus provides an aqueous, acidic, thickened agent for cleaning sanitary facilities, containing, in addition to water, 0.5-6% by weight of at least one weak acid, 2-8% by weight of at least one betaine and 0.2-10% by weight of at least one inorganic salt chosen from among alkali metal and alkaline earth metal chlorides and sulphates as well as possibly common additives such as perfume, bactericidal agent and colouring. The sanitary cleaning agent is characteristic in that the betaine or betaines are selected from among betaines with the general formulas:
hvor R er et alkyl- eller alkenylradikal med 9-17 carbonatomer og x og y uavhengig av hverandre er hele tall fra 1 til 5 i formel III, og hele tall fra 0 til 5 i formel IV, med det for-behold at x og y ikke begge er 0, where R is an alkyl or alkenyl radical with 9-17 carbon atoms and x and y independently of each other are whole numbers from 1 to 5 in formula III, and whole numbers from 0 to 5 in formula IV, with the proviso that x and y not both are 0,
og at vektforholdet mellom uorganisk salt og betain er lavere enn 2:1. and that the weight ratio between inorganic salt and betaine is lower than 2:1.
Den foreliggende oppfinnelse er å anse som en utvei-gelsesoppfinnelse hva angår kombinasjonen av betain, syre og salt, og det er nødvendig at alle disse tre bestanddeler er til stede i rengjøringsmidlet ifølge oppfinnelsen. I rengjø-ringsmidlet ifølge ovennevnte norske patentsøknad nr. 863666 er saltet en valgfri bestanddel, men når et salt er til stede, kan mengden av salt være større enn det dobbelte av mengden av det amfotere overflateaktive middel (betainet). I rengjørings-midlet ifølge oppfinnelsen er det uorganiske salt en viktig bestanddel som alltid må være til stede, og vektforholdet mellom uorganisk salt og betain er alltid lavere enn 2:1. The present invention is to be considered a balancing invention with regard to the combination of betaine, acid and salt, and it is necessary that all three of these components are present in the cleaning agent according to the invention. In the cleaning agent according to the above-mentioned Norwegian patent application no. 863666, the salt is an optional component, but when a salt is present, the amount of salt can be greater than twice the amount of the amphoteric surfactant (betaine). In the cleaning agent according to the invention, the inorganic salt is an important component which must always be present, and the weight ratio between inorganic salt and betaine is always lower than 2:1.
Med den foreliggende kombinasjon av tre obligatoriske bestanddeler og betainene med formler I og II oppnås en for-tykning av rengjøringsmidlet som er så stabil at den parfyme som ofte ønskes tilsatt rengjøringsmidler, kan tilføres mot slutten av blandeoperasjonen, uten at det finner sted separasjon i to faser. Dette å kunne tilsette en parfyme i sluttfa-sen av fremstillingen representerer som allerede nevnt en stor fordel for produsenten. Han kan nemlig da fremstille en blanding som ikke inneholder parfyme og ut fra én og samme hoved-blanding fremstille i et slutt-trinn ulike varianter av ren-gjøringsmidlet med ulike parfymetilsetninger. At de foreliggende rengjøringsmidler oppviser en stabilitet som gir denne frihet med hensyn til deres fremstilling, gjør sanitærrengjø-ringsmidlet ifølge oppfinnelsen overlegent i forhold til de tidligere kjente betainholdige sanitærrengjøringsmidler. With the present combination of three mandatory components and the betaines of formulas I and II, a thickening of the cleaning agent is achieved which is so stable that the perfume which is often added to cleaning agents can be added towards the end of the mixing operation, without separation into two taking place phases. Being able to add a perfume in the final phase of production represents, as already mentioned, a great advantage for the manufacturer. He can then produce a mixture that does not contain perfume and from one and the same main mixture produce in a final step different variants of the cleaning agent with different perfume additions. The fact that the present cleaning agents exhibit a stability that gives this freedom with regard to their manufacture makes the sanitary cleaning agent according to the invention superior to the previously known betaine-containing sanitary cleaning agents.
Vektforholdet mellom salt og betain i det nye sani-tærrengjøringsmiddel er fortrinnsvis lavere enn 1,5:1, mer foretrukket ca 1:1. I betainene med formel I foretrekkes det spesielt at x = y = 2. The weight ratio between salt and betaine in the new sanitation cleaner is preferably lower than 1.5:1, more preferably about 1:1. In the betaines of formula I, it is particularly preferred that x = y = 2.
Den svake syre velges fortrinnsvis blant maursyre, eddiksyre, citronsyre, melkesyre, ravsyre, gluconsyre, glutarsyre, adipinsyre, maleinsyre og blandinger av disse. The weak acid is preferably selected from formic acid, acetic acid, citric acid, lactic acid, succinic acid, gluconic acid, glutaric acid, adipic acid, maleic acid and mixtures thereof.
Saltet kan velges blant kloridene, bromidene, jodi-dene og sulfatene av alkalimetaller- eller jordalkalimetaller. Midlet er bemerkelsesverdig ved at det gjør det mulig å blande alle bestanddelene og å tilsette parfymen i slutt-trinnet. The salt can be selected from the chlorides, bromides, iodides and sulphates of alkali metals or alkaline earth metals. The agent is remarkable in that it makes it possible to mix all the ingredients and to add the perfume in the final step.
De følgende eksempler vil ytterligere illustrere oppfinnelsen. Med mindre annet er angitt, er mengdene gitt i vekt%. The following examples will further illustrate the invention. Unless otherwise stated, the quantities are given in % by weight.
Sammenlioningseksempel 1 Combination example 1
I den angitte rekkefølge blandes: In the specified order, mix:
- 9 g betain "Rewoteric AM-TEG" (<*>)(fremstilt av Rewo, og inneholdende 35-40% betain (III), 4,5-6% NaCl og vann opp til 100%. - 9 g betaine "Rewoteric AM-TEG" (<*>) (manufactured by Rewo, and containing 35-40% betaine (III), 4.5-6% NaCl and water up to 100%.
- 4 g HC1 (37%-ig) - 4 g HC1 (37% strength)
- 0,20 ml farvestoff (1% oppløsning i vann) - 0.20 ml dye (1% solution in water)
- 0,25 ml parfyme - 0.25 ml perfume
- 0,53 g bakteriedrepende middel (50% styrke) - 0.53 g bactericidal agent (50% strength)
- vann inntil 100 g. - water up to 100 g.
N-talg-N,N-bis-(2-hydroxyethyl)-glycinat N-tallow-N,N-bis-(2-hydroxyethyl)-glycinate
Det fåes et middel som har en viskositet på 150 mPa.s, målt med et viskosimeter av fabrikat Epprecht, med en spindel nr. 2 ved 200 rpm. An agent is obtained which has a viscosity of 150 mPa.s, measured with a viscometer made by Epprecht, with a spindle no. 2 at 200 rpm.
Sammenligninaseksempel 2 Comparative example 2
I den angitte rekkefølge blandes: In the specified order, mix:
- 9 g betain "AM-TEG" - 9 g betaine "AM-TEG"
- 1,33 g fosforsyre (75%-ig) - 1.33 g phosphoric acid (75% strength)
- 2,5 g maursyre (80%-ig) - 2.5 g formic acid (80%)
- 0,53 g bakteriedrepende middel (50% styrke) - 0.53 g bactericidal agent (50% strength)
- 0,20 ml farvestoff (1%) - 0.20 ml dye (1%)
- 0,25 ml parfyme - 0.25 ml perfume
- vann inntil 100 g. - water up to 100 g.
Dette middel er ikke viskøst (viskositet lavere enn 50 mPa.s). Dette eksempel viser således at betainet "AM-TEG" i blanding med svake syrer ikke gjør det mulig å oppnå en viskøs blanding. This agent is not viscous (viscosity lower than 50 mPa.s). This example thus shows that the betaine "AM-TEG" in a mixture with weak acids does not make it possible to obtain a viscous mixture.
Eksempel 1 Example 1
Til blandingen ifølge sammenligningseksempel 2 settes 3 g NaCl. 3 g of NaCl are added to the mixture according to comparative example 2.
Det fåes en blanding med en viskositet på 160 mPa.s, målt i et viskosimeter av fabrikat Epprecht, med spindel nr. 2 og ved 200 rpm. A mixture is obtained with a viscosity of 160 mPa.s, measured in a viscometer made by Epprecht, with spindle no. 2 and at 200 rpm.
Denne blanding er klar og gjennomsiktig og er lagringsstabil. This mixture is clear and transparent and is shelf-stable.
Eksempel 2 Example 2
Eksempel 1 gjentas, idet maursyren erstattes med eddiksyre og det tilsettes 3 g NaCl. Example 1 is repeated, replacing the formic acid with acetic acid and adding 3 g of NaCl.
Det fåes en blanding som har en viskositet på 180 mPa.s, og som er klar og gjennomsiktig samt stabil. A mixture is obtained which has a viscosity of 180 mPa.s, and which is clear and transparent as well as stable.
Eksempel 3 Example 3
De følgende bestanddeler blandes: The following ingredients are mixed:
- 9 g betain "TEGO N 192" fra Goldschmidt; dette har prak-tisk talt samme sammensetning som betainet "AM-TEG". - 9 g betaine "TEGO N 192" from Goldschmidt; this has practically the same composition as betaine "AM-TEG".
- 1,33 g fosforsyre (75%-ig) - 1.33 g phosphoric acid (75% strength)
- 2,5 g maursyre (80%-ig) - 2.5 g formic acid (80%)
- 0,20 ml farvestoff (1%) - 0.20 ml dye (1%)
- 0,25 ml parfyme - 0.25 ml perfume
- 0,53 g bakteriedrepende middel (50% styrke) - 0.53 g bactericidal agent (50% strength)
- 3 g NaCl - 3 g NaCl
- vann inntil 100 g. - water up to 100 g.
Det fåes en blanding med viskositet 145 mPa.s som inneholder 2% maursyre og 1% fosforsyre. A mixture with a viscosity of 145 mPa.s is obtained which contains 2% formic acid and 1% phosphoric acid.
Eksempel 4 Example 4
Innvirkningen av vektforholdet mellom betain (III) og salt undersøkes. The influence of the weight ratio between betaine (III) and salt is investigated.
Det fremstilles blandinger som angitt i eksempel 3, men mengden av betain og salt varieres. Mixtures are prepared as indicated in example 3, but the amount of betaine and salt is varied.
De følgende resultater oppnås: The following results are obtained:
Det sees at mengden av salt som tilsettes, ikke må være for stor. Det kan i alle fall konstateres at mengdefor-holdet mellom salt og betain må være mindre enn 2:1 og fortrinnsvis lik 1:1. For at viskositeten skal kunne bli av størrelsesorden 180 mPa.s i nærvær av en parfyme må dessuten mengden av betain være større enn 3 vekt%, fortrinnsvis 3,6 vekt%, og mengden av NaCl omtrent like stor, regnet i vekt%. It can be seen that the amount of salt added must not be too large. In any case, it can be stated that the quantity ratio between salt and betaine must be less than 2:1 and preferably equal to 1:1. In order for the viscosity to be of the order of 180 mPa.s in the presence of a perfume, the amount of betaine must also be greater than 3% by weight, preferably 3.6% by weight, and the amount of NaCl approximately the same, calculated in % by weight.
Eksempel 5 Example 5

- 0,5% citronsyre - 0.5% citric acid
- 0,5% fosforsyre - 0.5% phosphoric acid
- 2% maursyre - 2% formic acid
- 3,6% betain "AM-TEG" (100%) - 3.6% betaine "AM-TEG" (100%)
- 0,002% farvestoff - 0.002% dye
- 0,265% bakteriedrepende middel - 0.265% bactericidal agent
- 3% NaCl - 3% NaCl
- vann inntil 100%. - water up to 100%.
Det fåes en blanding med en viskositet på 520 mPa.s. Etter tilsetning av 0,25% parfyme fåes, alt etter arten av parfymen, en viskositet i området mellom 100 og 400 mPa.s. A mixture with a viscosity of 520 mPa.s is obtained. After the addition of 0.25% perfume, depending on the nature of the perfume, a viscosity in the range between 100 and 400 mPa.s is obtained.
Eksempel 7 Example 7
Den i eksempel 3 beskrevne blanding fremstilles, men tilførselsrekkefølgen endres, nemlig slik at parfymen tilføres til slutt under fremstillingen. Det fåes en stabil blanding hvis uklarhetspunkt ligger høyere enn +80°C. The mixture described in example 3 is prepared, but the order of addition is changed, namely so that the perfume is added at the end during the preparation. A stable mixture is obtained if the cloud point is higher than +80°C.
