Description
Den foreliggende oppfinnelse angår et fortykket, vandig rengjøringspreparat inneholdende alkalimetallhypokloritt. The present invention relates to a thickened, aqueous cleaning preparation containing alkali metal hypochlorite.
Fortykkede rengjøringspreparater oppviser den fordel Thickened cleaning preparations exhibit that advantage
at de hefter bedre til vertikale eller skrånende flater enn de som ikke er fortykkede og følgelig utøver en rengjørende og desinfiserende virkning som er mer effektiv på slike flater, såsom f.eks. toalettskåler, urinaler, vannlåser, osv. that they adhere better to vertical or sloping surfaces than those that are not thickened and consequently exert a cleaning and disinfecting effect that is more effective on such surfaces, such as e.g. toilet bowls, urinals, water traps, etc.
Hva spesielt angår fortykkede eller viskøse væskeprepa-rater som inneholder hypokloritt, spesielt et alkalisk hypokloritt og fortrinnsvis natriumhypokloritt, støter man ved utarbeidelsen av industrielle og kommersielle oppskrifter på tre typer vanskeligheter, nemlig: - fysikalsk stabilitet av oppløsningen i én enkelt fase, som fortrinnsvis er klar; - kjemisk stabilitet, d.v.s. begrenset nedbrytning (liten minskning med tiden av den klorometriske grad eller det prosentvise innhold av aktivt klor); - opprettholdelse av eller begrenset variasjon i viskositeten av preparatet, etter fremstillingen og under lagring. With particular regard to thickened or viscous liquid preparations containing hypochlorite, especially an alkaline hypochlorite and preferably sodium hypochlorite, three types of difficulties are encountered in the preparation of industrial and commercial recipes, namely: - physical stability of the solution in a single phase, which is preferably clear; - chemical stability, i.e. limited degradation (small decrease with time of the chlorometric degree or the percentage content of active chlorine); - maintenance of or limited variation in the viscosity of the preparation, after manufacture and during storage.
De væskeformige rengjøringspreparater på basis av hypokloritt som for tiden er tilgjengelige, gir ingen tilfredsstillende løsning på disse vanskeligheter sett under ett, spesielt ikke ved et høyt innhold av hypokloritt, spesielt ved et innhold høyere enn 20° klorometrisk. The liquid cleaning preparations based on hypochlorite which are currently available do not provide a satisfactory solution to these difficulties taken together, especially not at a high content of hypochlorite, especially at a content higher than 20° chlorometric.
Dessuten vil, når man ønsker å parfymere slike preparater, innføringen av en parfyme ytterligere forsterke disse vanskeligheter og i sin tur bidra til destabilisering av preparatene eller til tap av viskositet. Moreover, when one wishes to perfume such preparations, the introduction of a perfume will further intensify these difficulties and in turn contribute to the destabilization of the preparations or to a loss of viscosity.
Det er allerede blitt beskrevet rengjøringspreparater med hypokloritt inneholdende overflateaktive midler eller kombinasjoner av overflateaktive midler blant andre bestanddeler. Blant de publikasjoner som befatter seg med relevant kjent teknikk skal spesielt nevnes: - GB- 1. 128. 411, hvor det beskrives blekende vaskemidler med alkalimetallhypokloritt. Siktemålet, nemlig fremstilling av et væskeformig vaskemiddel som gir effektiv bleking, søkes oppnådd ved hjelp av en kombinasjon med den vandige hypoklorittoppløsning av et hydrotropt middel valgt blant mono- eller polyalkylerte benzen- eller naftalensulfonater og av et tensid. Dette sistnevnte kan være et aminoxyd og/ eller laurylethersulfonat, men det anvendes alltid sammen med en minst ekvivalent mengde av benzen- eller naftalensul-fonatderivatet. Dessuten er preparatene ikke fortykkede. Cleaning preparations with hypochlorite containing surfactants or combinations of surfactants among other ingredients have already been described. Among the publications dealing with relevant prior art, special mention should be made of: - GB- 1.128.411, where bleaching detergents with alkali metal hypochlorite are described. The aim, namely the production of a liquid detergent which provides effective bleaching, is sought to be achieved by means of a combination with the aqueous hypochlorite solution of a hydrotropic agent chosen from among mono- or polyalkylated benzene or naphthalene sulphonates and of a surfactant. This latter can be an amine oxide and/or lauryl ether sulphonate, but it is always used together with at least an equivalent amount of the benzene or naphthalene sulphonate derivative. Furthermore, the preparations are not thickened.

med hypokloritt, inneholdende et overflateaktivt middel med vaskeevne og om nødvendig et hydrotropt tensid. Det overflateaktive middel med vaskeevne kan være laurylethersulfat, og det hydrotrope tensid kan være et alkylarylsulfonat. Preparatene er ikke fortykkede, og deres stabilitet uttrykt with hypochlorite, containing a surface-active agent with detergency and, if necessary, a hydrotropic surfactant. The detergent surfactant may be lauryl ether sulfate, and the hydrotropic surfactant may be an alkyl aryl sulfonate. The preparations are not thickened, and their stability expressed
i klorometriske grader er ikke overbevisende. in chlorometric degrees is not convincing.
- GB- 1. 466. 560, hvor det beskrives et fortykket blekemiddel - GB- 1.466.560, where a thickened bleaching agent is described

De fremstilte preparater har bare moderat stabilitet, som sågar er utilstrekkelig for et hypokloritt med et høyt klorometrisk gradtall. - FR-2.25 3. 826, hvor det beskrives væskeformige blekende vaskemidler som inneholder et alkalisk hypokloritt, et overflateaktivt middel av typen sulfat eller carboxylat av nærmere angitt formel. Preparatene går for å være stabile, og det angis at dette ikke ville være tilfelle for vandige hypoklo-rittpreparater hvor det forekommer laurylethersulfat. ammonium compound, an amine oxide, a betaine, an alkanolamide and mixtures thereof. The prepared preparations have only moderate stability, which is insufficient even for a hypochlorite with a high chlorometric degree number. - FR-2.25 3.826, where liquid bleaching detergents are described which contain an alkaline hypochlorite, a surface-active agent of the sulfate or carboxylate type of the specified formula. The preparations are supposed to be stable, and it is stated that this would not be the case for aqueous hypochlorite preparations where lauryl ether sulphate occurs.

som inneholder et alkalimetallhypokloritt, og som er fortykket ved hjelp av et forgrenet Cg-C-^-aminoxyd, og som dessuten eventuelt inneholder et rettkjedet C^-C^-aminoxyd og/eller et alkalimetallsalt av Cg-C^-fettsyre som hjelpefortykningsmidler. Det dreier seg der om et utvalg av spesielle oxydaminer, som foreslås som et middel som vil gi en bedre fortykning enn den tidligere kjente kombinasjon av et konvensjonelt aminoxyd og et fettsyre-alkalimetallsalt. - EP- 9942, hvor det beskrives hellbare vaske- og skuremidler som inneholder NaOCl, et anionisk overflateaktivt middel, which contains an alkali metal hypochlorite, and which is thickened with the help of a branched Cg-C-^-amine oxide, and which also optionally contains a straight-chain C^-C^-amine oxide and/or an alkali metal salt of Cg-C^-fatty acid as auxiliary thickening agents . It concerns a selection of special oxydamines, which are proposed as an agent that will give a better thickening than the previously known combination of a conventional amine oxide and a fatty acid-alkali metal salt. - EP-9942, which describes pourable detergents and scrubbers containing NaOCl, an anionic surfactant,
et aminoxyd, en elektrolytt og et oppslemmet partikkelformig slipemiddel. Det angis at det anioniske overflateaktive middel fortrinnsvis er et alkylsulfat, et alkylbenzensulfo-nat eller et sek-alkansulfonat, men de ethoxylerte overflateaktive midler, som er utilstrekkelig motstandsdyktige mot å oxyderes av hypokloritt, må unngås. De tilsvarende preparater oppviser ingen markert viskositet, og de oppviser an amine oxide, an electrolyte and a slurried particulate abrasive. It is stated that the anionic surfactant is preferably an alkyl sulfate, an alkylbenzene sulfonate or a sec-alkanesulfonate, but the ethoxylated surfactants, which are insufficiently resistant to being oxidized by hypochlorite, must be avoided. The corresponding preparations show no marked viscosity, and they show
bare en moderat stabilitet. only a moderate stability.

It is specified that it is absolutely necessary that the thickening regimen includes at least one representative of each of the three above-mentioned classes of (A), (B) and (C) of surfactants. It is clearly stated, on the other hand, that the present problem, which this preparation aimed to solve, was the problem of a precise adaptation of the viscosity properties of hypochlorite preparations intended for cleaning pipes.

- EP- 110 . 544 , hvor det beskrives fortykkede blekemidler som inneholder et alkalimetallhypokloritt og, som eneste fortykningsmiddel, et rettkjedet aminoxyd med minst 14 carbonatomer i denne uforgrenede kjede. Denne løsning på problemet med å fortykke hypoklorittoppløsninger er ikke vesentlig bedre enn de øvrige. Den synes å anbefales av opphavsmannen av økonomiske grunner. - EP-110. 544, where thickened bleaching agents are described which contain an alkali metal hypochlorite and, as the only thickening agent, a straight-chain amine oxide with at least 14 carbon atoms in this unbranched chain. This solution to the problem of thickening hypochlorite solutions is not significantly better than the others. It seems to be recommended by the originator for financial reasons.
Det fremgår av alle de ovenfor omtalte teknikker at fagmannen langt fra hadde til rådighet fullt ut tilfredsstillende løsninger på de problemer som knytter seg til fortykning av vandige hypoklorittoppløsninger og stabilisering av disse fortykkede oppløsninger. Det synes tvert imot at fagman- It appears from all the above-mentioned techniques that the person skilled in the art was far from having at his disposal fully satisfactory solutions to the problems linked to the thickening of aqueous hypochlorite solutions and the stabilization of these thickened solutions. On the contrary, it seems that professionals

There was thus a need for a thickened, aqueous cleaning preparation containing an agent for the formation of hypochlorite ions C10~ in solution, which would be able to satisfy the above-mentioned acceptability criteria, namely a sufficient viscosity and satisfactory physical and chemical stability, and especially for preparations with a high content of material that forms ions CIO<->. The present invention aims to provide such a preparation.

For fremstillingen av disse preparater tilrådes det For the production of these preparations it is recommended
å gå frem som følger (N.B.: Dersom det ønskes tilsatt en parfyme, vil det være hensiktsmessig å tilberede en forblanding av aminoxyd og parfyme): Under kontinuerlig omrøring tilsettes til hypoklorittet natriumhydroxydet, vannet og natriumsaltet (dersom ikke dette på forhånd er blitt tilsatt til vannet) og deretter aminoxydforbindelsen eller aminoxydforbindelsen + parfyme og de øvrige overflateaktive midler. to proceed as follows (N.B.: If it is desired to add a perfume, it would be appropriate to prepare a premix of amine oxide and perfume): With continuous stirring, add the sodium hydroxide, the water and the sodium salt to the hypochlorite (if this has not been added to the the water) and then the amine oxide compound or the amine oxide compound + perfume and the other surfactants.
Hva angår den om nødvendig tilsatte mengde vann, star-ter man med den på forhånd grovt utregnede mengde og foretar en justering til slutt, i avhengighet av den klorometriske titer av hypoklorittet og av oppløsningen. With regard to the quantity of water added if necessary, one starts with the roughly calculated quantity in advance and makes an adjustment at the end, depending on the chlorometric titer of the hypochlorite and the solution.
