Description
i DK 170947 B1in DK 170947 B1
Den foreliggende opfindelse angår kompositioner til rengøring og nærmere bestemt kompositioner, som anvendes i sanitære installationer, f.eks. i toiletkummer.The present invention relates to cleaning compositions and more particularly to compositions used in sanitary installations, e.g. in the toilet.
Et af de vigtigste problemer, som rejses med sådanne kompo-5 sitioner, er, at de bør kunne fjerne den kalk, som aflejres på overfladen af kummen. Hertil er det kendt at anvende vandige kompositioner, som indeholder mindst én syre, såsom saltsyre, phosphor-syre, svovlsyre, eddikesyre eller fumarsyre.One of the most important problems raised with such compositions is that they should be able to remove the lime deposited on the surface of the basin. For this purpose, it is known to use aqueous compositions containing at least one acid such as hydrochloric acid, phosphoric acid, sulfuric acid, acetic acid or fumaric acid.
Men de kompositioner, som indeholder saltsyre, er korroderende 10 og farlige, og man foretrækker at anvende svage syrer.However, the compositions containing hydrochloric acid are corrosive and dangerous, and weak acids are preferred.
Det er også kendt at forbedre rengøringskompositionernes ved-hængen på kummens skrå sider ved at tilsætte et fortykningsmiddel. Således tilsættes ofte anioniske og/eller ikke-ioniske overfladeaktive midler eller andre fortykningsmidler, såsom polyethoxylerede *5 aminer eller cellulosederivater, såsom carboxymethylcellulose.It is also known to improve the adhesion of the cleaning compositions to the sloping sides of the basin by adding a thickener. Thus, anionic and / or nonionic surfactants or other thickening agents such as polyethoxylated * 5 amines or cellulose derivatives such as carboxymethyl cellulose are often added.
For at disse fortykningsmidler kan anvendes, er det almindeligvis nødvendigt at tilsætte tilsætningsstoffer, f.eks. alkoholer, for at opløse carboxymethylcellul osen i vand.In order for these thickeners to be used, it is generally necessary to add additives, e.g. alcohols, to dissolve carboxymethyl cellulene in water.
For fortyknede, sure kompositioner, som anvendes i sanitære 20 installationer, bør pH-intervallet vælges således, at tilsætningen og stabiliteten af parfumer i kompositionen ikke vanskeliggøres. Faktisk fremkalder pH-værdier på under 1,5 en nedbrydning af hoved-bestanddelene af størstedelen af parfumerne.For thickened, acidic compositions used in sanitary installations, the pH range should be chosen so that the addition and stability of perfumes in the composition is not difficult. In fact, pH values of less than 1.5 cause a breakdown of the main constituents of most perfumes.
Viskositeten af sådanne kompositioner bør også vælges på en 25 sådan måde, at der opnås en tilfredsstillende afkalkende evne og en rest af parfumer, som er eftertragtet af brugerne. Men en utilstrækkelig viskositet gør det ikke muligt for rensekompositionen at hænge fast på siderne i tilstrækkelig grad, hvilket formindsker kontakttiden mellem kompositionen og kalken. I modsætning hertil forhindrer en for høj viskositet diffusion af parfumen i luften omkring toilettet eller en diffusion i det vand, der bliver tilbage i bunden af toilettet.The viscosity of such compositions should also be chosen in such a way as to obtain a satisfactory descaling ability and a residue of perfumes sought by the users. However, an insufficient viscosity does not allow the cleaning composition to adhere to the sides sufficiently, reducing the contact time between the composition and the lime. In contrast, an excessive viscosity prevents diffusion of the perfume into the air around the toilet or a diffusion into the water remaining at the bottom of the toilet.
Det er således et formål med opfindelsen at tilvejebringe en vandig, sur, fortyknet komposition, som ikke indeholder stærke 35 syrer, men som har en tilfredsstillende afkalkende virkning.It is thus an object of the invention to provide an aqueous, acidic, thickened composition which does not contain strong acids, but which has a satisfactory descaling effect.
Et andet formål med opfindelsen er at tilvejebringe en sådan afkalkende komposition, som har en viskositet, der kan reguleres, til tilvejebringelse af en god vedhængen på de skrå sider og på samme tid en diffusion af parfume i den omgivende luft.Another object of the invention is to provide such a descaling composition which has a controllable viscosity to provide a good adhesion on the inclined sides and at the same time a diffusion of perfume into the ambient air.

Et tredie formål med opfindelsen er at tilvejebringe en fortyknet, parfumeret, sur, vandig komposition, som samtidig er farvet, klar og gennemsigtig, stabil ved omgi vel sestemperatur og op til +40°C i flere måneder.A third object of the invention is to provide a thickened, perfumed, acidic, aqueous composition which is simultaneously colored, clear and transparent, stable at ambient room temperature and up to + 40 ° C for several months.
5 Et yderligere formål med opfindelsen er at tilvejebringe en afkalkende komposition til sanitær rengøring, hvilken komposition kun indeholder ét overfladeaktivt fortykningsmiddel for at formindske fremstillingsomkostningen.A further object of the invention is to provide a descaling composition for sanitary cleaning, which composition contains only one surfactant thickener to reduce the cost of manufacture.
Oer kendes fortykningssystemer, som indeholder en amidobetain med formlen: (CH2)y-CH3 9 R-C-NH-(CH2)n-N+-CH2-C02‘ (I) N / 15 o (CH2)y-CH3 hvor R betegner et al kyl- eller alkenyl radikal, som indeholder fra 9 til 17 carbonatomer, n er et helt tal på fra 2 til 4, y er O eller et helt tal på fra 1 til 3, samt et salt udvalgt blandt alkalimetal- 20 og jordalkalimetalsulfater.There are known thickening systems containing an amidobetaine of the formula: (CH 2) γ-CH 3 9 RC-NH- (CH 2) n-N + -CH 2 -CO 2 '(I) N / 15 o (CH 2) any carbon or alkenyl radical containing from 9 to 17 carbon atoms, n is an integer of 2 to 4, y is 0 or an integer of 1 to 3, and a salt selected from alkali metal and alkaline earth metal sulfates.
Sådanne fortykningssystemer er beskrevet i EP patent nr.Such thickening systems are described in EP patent no.
0077674 (UNILEVER). I dette patentskrift nævnes, at de betainer, som ikke bærer en amidogruppe, ikke kan fortykke vandige kompositioner.0077674 (UNILEVER). It is mentioned in this patent that those betaines which do not carry an amido group cannot thicken aqueous compositions.
Der nævnes også, at amido-betainerne ikke kan fortykkes med et salt, 25 som er natriumchlorid eller natriumbromid. Endelig citeres en LONZA-publi kation, i hvilken en cocoamidobetain, som indeholder natriumchlorid, ikke kan fortykkes ved tilsætning af et anionisk overfladeaktivt middel.It is also mentioned that the amido betaine cannot be thickened with a salt which is sodium chloride or sodium bromide. Finally, a LONZA publication is cited in which a cocoamidobetain containing sodium chloride cannot be thickened by the addition of an anionic surfactant.
I EP patent nr. 0056595 (WELLCOME FOUNDATION) beskrives sham-30 pookompositioner, som indeholder en betain med formlen: ch3 / CH,-N+-CH,-C0,' (II) 35 3 , 2 2 ch3 og en organisk syre.EP Patent No. 0056595 (WELLCOME FOUNDATION) discloses shampoo compositions containing a betaine of the formula: ch 3 / CH, -N + -CH, -CO, (II) 35, 2, 2 ch 3 and an organic acid.
Disse kompositioner kan fremstilles i form af geler, således at DK 170947 B1 3 man tilsætter dem et fortykningsmiddel, såsom et overfladeaktivt middel, f.eks. en ethoxyleret nonylphenol, eller en polymer, f.eks. et cellulosederivat.These compositions may be prepared in the form of gels, so that a thickener such as a surfactant, e.g. an ethoxylated nonylphenol, or a polymer, e.g. a cellulose derivative.
Men ansøger har nu overraskende fundet og i modsætning til det, 5 som er blevet foreslået i de tidligere publikationer, at en betain, som ikke bærer en amidogruppe, i nærværelse af svage syrer kan fortyknes med halogenider eller sulfater af alkalimetaller eller jordal kalimetal ler.But applicant has now surprisingly found, and contrary to what has been suggested in previous publications, that a betaine which does not carry an amido group in the presence of weak acids can be thickened with halides or sulphates of alkali metals or alkaline earth metal clays.
De betainer, som er udvalgt af ansøger til at fortykne vandige 10 kompositioner, der indeholder mindst én svag syre, i nærværelse af et halogenid af et alkalimetal eller et jordalkalimetal, udvælges blandt betainer, som har følgende almene formel:The betaines selected by the applicant to thicken aqueous compositions containing at least one weak acid, in the presence of a halide of an alkali metal or an alkaline earth metal, are selected from betainees having the following general formula:
(CH2) -OH(CH 2) -OH
15 » R-CH2-N+-CH2-C02‘ (III) /R-CH 2 -N + -CH 2 -CO 2 '(III) /
(CH2)y-OH(CH 2) y OH
20 eller følgende almene formel: (CH2>X”CH3 t R-CH?-N+-CH?-C0?" (IV) 25 / (CH2)y-CH3 hvor R betegner et C9'C17 -alkyl- eller -al kyl radikal, x og y er uafhængige af hinanden og er hele tal på fra 1 til 5 for formel (III) ^0 og på fra 0 til 5 for formel (IV).Or the following general formula: (CH2> X "CH3 to R-CH2 -N + -CH2 -CO2" (IV) 25 / (CH2) y -CH3 where R represents a C9-C17 alkyl or -al cool radicals, x and y are independent of each other and are integers from 1 to 5 for formula (III) ^ 0 and from 0 to 5 for formula (IV).
Det har overraskende vist sig, at betainerne med formlerne III og IV ikke alene fortykner svagt sure, vandige kompostioner og gør dette i nærværelse af et halogenid af alkalimetal eller et jordal kalimetal, men også tillader at bringe parfumer i dispersion, hvilke ^ parfumer kan tilføres ved slutningen af blandingen, uden at der derved sker en separation i to faser. Den kendsgerning, at man kan tilsætte en parfume til slut i formulationen, er imidlertid en stor fordel for industrien. Faktisk kan der fremstilles en blanding, som DK 170947 B1 4 ikke indeholder parfume, og til samme blanding kan man til sidst tilsætte en parfume, som kan varieres efter forbrugernes smag og vaner.Surprisingly, it has been found that not only do the betaines of formulas III and IV thicken slightly acidic aqueous compositions and do so in the presence of a halide of alkali metal or a terrestrial potassium, but also allow to disperse perfumes which can be added to perfumes. at the end of the mixture without separating into two phases. However, the fact that one can add a perfume to the end of the formulation is a major benefit to the industry. In fact, a blend that does not contain perfume can be prepared, and to the same blend one can eventually add a perfume which can be varied according to the taste and habits of the consumer.
De betainer, som er udvalgt af ansøgeren, tillader desuden at 5 frembringe gennemsigtige og klare kompositioner, som er stabile under opbevaring ved en temperatur på fra omgivelsestemperatur og indtil +40°C.In addition, the applicator selected by the applicant allows to produce transparent and clear compositions which are stable under storage at a temperature of from ambient temperature up to + 40 ° C.
Opfindelsen angår således en sur, fortyknet, vandig komposition til sanitær rengøring, hvilken komposition er ejendommelig ved, at den indeholder mindst én betain udvalgt blandt betainer, som har formlen (III) eller (IV), mindst én svag syre, mindst ét salt, eventuelt en parfume, eventuelt et baktericid, eventuelt et farvestof og vand.The invention thus relates to an acidic, thickened, aqueous composition for sanitary cleaning, the composition being characterized in that it contains at least one betaine selected from betaine having the formula (III) or (IV), at least one weak acid, at least one salt, optionally a perfume, optionally a bactericide, optionally a dye and water.
Salt/betain-vægtforholdet ligger fortrinsvis under 1,5:1.The salt / betaine weight ratio is preferably below 1.5: 1.
15 Kompositionen indeholder fra 0,5 til 10 vægtprocent af mindst én betain med formlen (III) eller (IV) og fra 0,1 til 15 vægtprocent af mindst ét salt.The composition contains from 0.5 to 10% by weight of at least one betaine of formula (III) or (IV) and from 0.1 to 15% by weight of at least one salt.
Den indeholder fortrinsvis fra 2 til 8 vægtprocent af mindst én betain med formlen (III) eller (IV), fra 0,5 til 6 vægtprocent af 20 mindst én svag syre, fra 0,2 til 10 vægtprocent af et salt.It preferably contains from 2 to 8 weight percent of at least one betaine of formula (III) or (IV), from 0.5 to 6 weight percent of at least one weak acid, from 0.2 to 10 weight percent of a salt.
Hvad angår betainen foretrækkes navnlig de betainer, hvor x * y - 2 for en betain med formlen (III), og de betainer, hvor x = y * 0 for en betain med formlen (IV).In the case of the betaine, in particular, the betaine where x * y - 2 is preferred for a betaine of formula (III) and those betaine where x = y * 0 for a betaine of formula (IV).
Den svage syre vælges fortrinsvis blandt myresyre, eddikesyre, 25 citronsyre, mælkesyre, ravsyre, gluconsyre, glutarsyre, adipinsyre, æblesyre eller blandinger heraf.The weak acid is preferably selected from formic acid, acetic acid, citric acid, lactic acid, succinic acid, gluconic acid, glutaric acid, adipic acid, malic acid or mixtures thereof.
Saltet kan udvælges blandt chlorider, bromider, iodider og sulfater af alkalimetaller eller jordalkalimetaller. Kompositionen er bemærkelsesværdig ved, at den muliggør sammenblanding af alle 30 bestanddele og tilsætning af parfumen i sluttrinnet.The salt can be selected from chlorides, bromides, iodides and sulfates of alkali metals or alkaline earth metals. The composition is remarkable in that it allows mixing all 30 ingredients and adding perfume in the final step.
Den efterfølgende beskrivelse, hvad angår de tilknyttede eksempler, gør det muligt at forstå, hvordan opfindelsen kan udføres i praksis. Med mindre andet er angivet er mængderne angivet i vægtprocenter.The following description, with respect to the accompanying examples, makes it possible to understand how the invention can be carried out in practice. Unless otherwise stated, the amounts are given in weight percentages.

Sammen!ioninoseksempel nr. 1 I rækkefølge blandedes følgende: 9 g REWOTERIC AM-TEG betain (*)(fremstillet af REWO og indeholder 35-40% betain (III), 4,5-6,0% NaCl, vand til 100%).Comparative Example # 1, the following were mixed: 9 g REWOTERIC AM-TEG betaine (*) (made from REWO and containing 35-40% betaine (III), 4.5-6.0% NaCl, water to 100% ).

Der opnåedes en komposition, som havde en viskositet på 150 mPas, målt med et Epprecht-viskosimeter med et drivhjul på 2, en 10 hastighed på 200 omdrejninger/minut.A composition having a viscosity of 150 mPas was obtained, measured with an Epprecht viscometer with a drive wheel of 2, a speed of 200 rpm.
Sammenlianinoseksempel nr. 2 I rækkefølge blandedes følgende: 9 g AM-TEG-betain ^ 1,33 g phosphorsyre (å 75%) 2,5 g myresyre (å 80%) 0,53 g baktericid (å 50%) 0,20 ml farvestof (å 1%) 0,25 ml parfume vand til 100 g.Comparison of Example 2, in sequence, was mixed as follows: 9 g AM-TEG-betaine ^ 1.33 g phosphoric acid (75%) 2.5 g formic acid (80%) 0.53 g bactericidal (50%) 0.20 ml of dye (to 1%) 0.25 ml of perfume water to 100 g.
Denne komposition var ikke viskøs (mindre end 50 mPas). Dette eksempel viser således, at AMTEG-betainen i blanding med svage syrer ikke gør det muligt at opnå en viskøs komposition.This composition was not viscous (less than 50 mPas). Thus, this example shows that the AMTEG betaine in admixture with weak acids does not allow a viscous composition to be obtained.

Eksempel 4Example 4
Indflydelsen af vægtforholdet mellem betain (III) og saltet blev undersøgt.The influence of the weight ratio of betaine (III) to salt was investigated.
Der fremstilledes de samme blandinger som i eksempel 1, men 70 mængden af betain og mængden af saltet blev varieret.The same mixtures were prepared as in Example 1, but the amount of betaine and the amount of salt varied.
Der opnåedes følgende resultater:The following results were obtained:
% AM-TEG% AM-TEG
(som indeholder Viskositet 25 ca. 5% NaCl og % NaCl % NaCl eller 35% betain) tilsat total Salt/betain udseende 8 5 5,4 1,8 2 faser 6 5,5 5,8 2,4 2 faser 6.5 5 5,33 2,1 2 faser 30 7 2,3 2,46 1 92 mPas 9 3 3,27 1 200 mPas(containing Viscosity 25 about 5% NaCl and% NaCl% NaCl or 35% betaine) added Total Salt / betaine appearance 8 5 5.4 1.8 2 phases 6 5.5 5.8 2.4 2 phases 6.5 5 5.33 2.1 2 phases 30 7 2.3 2.46 1 92 mPas 9 3 3.27 1 200 mPas
Det fremgår således, at mængden af tilsat salt ikke bør være for stor; i alle tilfælde har man kunnet konstatere, at salt/betain-35 forholdet bør ligge under 2:1 og fortrinsvis være lig med 1:1. For i nærværelse af en parfume at give en viskositet af størrelsesorden 180 mPas bør mængden af betain desuden ligge over 3 vægtprocent, fortrinsvis 3,6 vægtprocent, og mængden af NaCl bør stort set være lige så stor angivet i vægtprocent.Thus, it appears that the amount of salt added should not be excessive; in all cases, it has been found that the salt / betaine ratio should be less than 2: 1 and preferably equal to 1: 1. In addition, in order to provide a viscosity of about 180 mPas in the presence of a perfume, the amount of betaine should be above 3% by weight, preferably 3.6% by weight, and the amount of NaCl should be approximately equal in weight%.
