Description
Oppfinnelsen vedrører en fremgangsmåte til fremstilling av svaktskummende vaskemiddel under anvendelse av fosforsyrepartialestere som skumdempende stoff. The invention relates to a method for producing low-foaming detergent using phosphoric acid partial esters as anti-foaming agents.
Vaskemidler, som skal finne anvendelse i hushold-ningsvaskemaskiner må disponere over en nedsatt resp. regulert skumevne, for at det ikke kommer til overskumming av vaskebadet i vaskeprosessen, da herved på den ene side begrenses den fri bevegelse av vaskegodset og på den annen side frembringes be-skadigelser på vaskemaskinens elektriske innretninger. Av denne grunn ble det til de hittil fortrinnsvis anvendte, spesielt overflateaktive tensider som alkylbenzensulfonater, alkansulfonater og alkyletersulfonater ved siden av svaktskummende ikke-ionogene tensider satt betraktelige mengder av langkjedede al-kalisåper og/eller langkjedede fosforsyredelestere, for herved å oppnå en akseptabel skumregulering. Det har imidlertid vist seg at i høyere temperaturområder på over 70°C og i mykt vann med en vannhårdhet på mindre enn 10°dH med slike tensidkombina-sjoner i vaskepulvere, som ble fremstillet etter varmforstøv-ningsfremgangsmåten ikke alltid gir en tilfredsstillende skumdempning og overskumming inntrer. Detergents that are to be used in household washing machines must have a reduced or regulated foaming ability, so that there is no overfoaming of the washing bath during the washing process, as this on the one hand limits the free movement of the laundry and on the other hand causes damage to the washing machine's electrical devices. For this reason, considerable amounts of long-chain alkali soaps and/or long-chain phosphoric acid delesters were added to the hitherto preferentially used surfactants such as alkylbenzenesulfonates, alkanesulfonates and alkylethersulfonates alongside low-foaming non-ionic surfactants, in order to thereby achieve an acceptable foam control. However, it has been shown that in higher temperature ranges of over 70°C and in soft water with a water hardness of less than 10°dH with such surfactant combinations in washing powders, which were produced according to the hot atomization method, do not always provide satisfactory foam suppression and overfoaming enters.
Denne ulempe er også tilfellet for de etter fremgangsmåten ifølge DAS I.617.I6O fremstilte rensemidler. Gjen-standen for DAS I.617.I6O er en fremgangsmåte til fremstilling av forstøvningstørkede rensepreparater fra vandige oppslemninger som inneholder overflateaktive etylenoksyd-addukter og organiske samt uorganiske tilsetningsstoffer, som idet fremgangsmåten erkarakterisert vedat man før, under eller etter fremstillingen av den vandig-e oppslemning til denne setter en eller flere fosfatestere eller alkalisalter eller ammoniumsalter og deretter forstøvningstørker den dannede oppslemning på i og for seg kjent måte. This disadvantage is also the case for the cleaning agents produced according to the method according to DAS I.617.I60. The object of DAS I.617.I6O is a method for the production of spray-dried cleaning preparations from aqueous slurries containing surface-active ethylene oxide adducts and organic and inorganic additives, which as the method is characterized by the fact that before, during or after the production of the aqueous slurry to this add one or more phosphate esters or alkali salts or ammonium salts and then spray-dry the formed slurry in a manner known per se.
Det ble overraskende funnet at ved anvendelse av fosforsyrepartialestere i vaskemidlet avhenger graden av den • med overnevnte stoffer i vaskebadet oppnåelige skumdempning av i hvilke fase av fremstillingsfremgangsmåten av vaskemidlet fosforsyrepartialesteren innbringes i vaskemiddelformuleringen. Således ble det erkjent at ved innarbeidelse av fosforsyrepartialester i den vandige oppslemning av vaskemiddelkomponentene ifølge DAS I.617.I6O fåes et vaskemiddel som ikke har optimal skumdempning. Denne erkjennelse er forsåvidt overraskende som fosforsyrepartialestere som kjent er relativt temperatur- og hydrolysebestandige og spaltning eller partiell avbygning av esteren under tilberedningen av den vandige oppslemning av vaskemiddelkomponentene eller under varmforstøvningstørkningen av oppslemningen ikke er å vente. It was surprisingly found that when phosphoric acid partial esters are used in the detergent, the degree of foam reduction achievable with the above-mentioned substances in the wash bath depends on in which phase of the detergent manufacturing process the phosphoric acid partial ester is introduced into the detergent formulation. Thus, it was recognized that when phosphoric acid partial esters are incorporated into the aqueous slurry of the detergent components according to DAS I.617.I60, a detergent is obtained which does not have optimal foam suppression. This realization is certainly surprising as phosphoric acid partial esters are known to be relatively temperature and hydrolysis resistant and cleavage or partial decomposition of the ester during the preparation of the aqueous slurry of the detergent components or during the hot spray drying of the slurry is not to be expected.
Ulempene ifølge DAS 1.617.160 overvinnes ved foreliggende oppfinnelse. The disadvantages according to DAS 1,617,160 are overcome by the present invention.

Eksempler By anionic surfactants is meant the water-soluble salts of higher fatty acids or resin acids, such as sodium or potassium soaps of hardened or unhardened coconut palm kernel or rapeseed oil as well as of tallow and corresponding mixtures thereof. Furthermore, anionic active substances within the scope of the invention are to be understood as higher alkyl substituted mononuclear, aromatic sulphonates, such as alkylbenzene sulphonates with 9 to 1^ C atoms in the alkyl residue, alkyl naphthalene sulphonates, alkyl toluene sulphonates, alkyl xylene sulphonates or alkylphenol sulphonates as well as sulphated aliphatic alcohols or alcohol ethers such as sodium or potassium lauryl resp. -hexadecyl sulphate, triethanolamine lauryl sulphate, sodium or potassium oleyl sulphate and sodium or potassium salts of approx. 2 to 6 moles of ethyl ethoxylated lauryl sulfate. Further suitable anionic surfactants are secondary linear alkanesulfonates and α-olefinsulfonates with a chain length of 12-20 C atoms. By non-ionic surfactants, it is within the scope of the invention to understand such compounds which have an organic hydrophobic group as well as a hydrophilic residue. Examples

Ved fremgangsmåten ifølge oppfinnelsen anvendes som vaskeaktive stoffer eksempelvis natriumdodecylbenzensulfonat, talgfettalkoholetoksylat med 11-15 mol etylenoksyd pr. mol fettalkohol, herdede tålgsåper, palmitinfettaminetoksylat med 8-15 mol etylenoksyd pr. mol fettamin elier lauryletersulfat med 2-6 mol etylenoksyd pr. mol laurylalkohol. In the method according to the invention, for example, sodium dodecylbenzene sulphonate, tallow fat alcohol ethoxylate with 11-15 mol of ethylene oxide per moles of fatty alcohol, hardened tallow soaps, palmitic fat amine ethoxylate with 8-15 moles of ethylene oxide per mol of fatty amine or lauryl ether sulfate with 2-6 mol of ethylene oxide per moles of lauryl alcohol.
Vaskehjelpestoffer ifølge oppfinnelsen omfatter produkter som f.eks. uorganiske eller kompleksdannere, alkali-eller ammoniumsalter av svovelsyre, kiselsyre, karbonsyre, borsyre, alkylen-, hydroksyalkylen- eller aminoalkylenfosfon-syre. Spesielt anvendes som. vaskehjelpestoffer natriumtripoly-f osf at, tetranatriumdif osf at, dinatriumdihydro.genf osf at, natriumsulfat, natriumkarbonat, natrium- resp. magnesiummetasilikat eller natriumperborat-tetrahydrat. Washing aids according to the invention include products such as e.g. inorganic or complexing agents, alkali or ammonium salts of sulfuric acid, silicic acid, carbonic acid, boric acid, alkylene, hydroxyalkylene or aminoalkylenephosphonic acid. Especially used as. detergents sodium tripolyphosphate, tetrasodium diphosphate, disodium dihydrogen phosphate, sodium sulfate, sodium carbonate, sodium resp. magnesium metasilicate or sodium perborate tetrahydrate.
Stoffer som øker vaskebadets smussbæreevne som karboksymetylcellulose, karboksymetylstivelse, polyvinylalkohol eller polyvinylpyrrolidon samt stabilisatorer for peroksyd-forbindelser eller desinfeksjonsmidler og/eller proteolytiske enzymer kan likeledes være bestanddeler av det ved fremgangsmåten ifølge oppfinnelsen fremstilte vaskemiddel, idet det som egnede stabilisatorer for peroksyder er å nevne utfelt magnesiumsilikat, nitrilotrieddiksyre og etylendiamintetraeddiksyre. Substances that increase the dirt carrying capacity of the washing bath such as carboxymethyl cellulose, carboxymethyl starch, polyvinyl alcohol or polyvinyl pyrrolidone as well as stabilizers for peroxide compounds or disinfectants and/or proteolytic enzymes can likewise be components of the detergent produced by the method according to the invention, as suitable stabilizers for peroxides are precipitates magnesium silicate, nitrilotriacetic acid and ethylenediaminetetraacetic acid.
En ytterligere foretrukket fremgangsmåte ifølge oppfinnelsen består i, som skumdempende stoff å anvende mono- A further preferred method according to the invention consists in using mono-
eller dilauryletoksylatfosforsyreester med ty mol etylenoksydor dilauryl ethoxylate phosphoric acid ester with ty moles of ethylene oxide
pr. mol laurylalkohol, mono- eller distearyl-fosforsyreester, mono- eller distearyl-etoksylatfosforsyreester med 2 mol etylenoksyd pr. mol stearylalkohol, mono- eller dioleyletoksylat-fosforsyreester med 4 mol etylenoksyd pr. mol oleylalkohol eller en blanding av mono- og- diesteren. Innholdet av det skumdempende stoff i det ferdige vaskemiddel utgjør ca. 0,2 - 2 vekt%. per mol lauryl alcohol, mono- or distearyl phosphoric acid ester, mono- or distearyl ethoxylate phosphoric acid ester with 2 mol ethylene oxide per mol of stearyl alcohol, mono- or diolley ethoxylate phosphoric acid ester with 4 mol of ethylene oxide per moles of oleyl alcohol or a mixture of the mono and diester. The content of the foam suppressant in the finished detergent amounts to approx. 0.2 - 2% by weight.
Endelig finnes det forskjellige muligheter til å forene det skumdempende stoff med det av de øvrige vaskemiddelkomponenter eller en del av disse komponenter ved varmforstøv-ningstørkning fremstilte forprodukter. Således kan man eksempelvis mekanisk sammenblande forproduktene, eventuelt i blanding med natriumperborattetrahydrat, med det skumdempende stoff eller å sprøyte med det flytendegjorte skumdempende stoff under samtidig blanding av .forproduktet. Finally, there are various possibilities to combine the anti-foam substance with the precursors produced from the other detergent components or part of these components by hot spray drying. Thus, for example, one can mechanically mix the pre-products, possibly in a mixture with sodium perborate tetrahydrate, with the anti-foam substance or spray with the liquefied anti-foam substance while simultaneously mixing the pre-product.
Ytterligere forétrukkede alternativer består i at man mekanisk blander forproduktet med natriumtripolyfos fat, Further preferred alternatives consist of mechanically mixing the precursor with sodium tripolyphos barrels,
som er sprøytet med det skumdempende stoff eller at man dusjer forproduktet med en flytende blanding av det skumdempende stoff, det vaskeaktive,stoff og natriumperborat under samtidig blanding av forproduktet. that has been sprayed with the anti-foam substance or that the pre-product is showered with a liquid mixture of the anti-foam substance, the detergent active substance and sodium perborate while simultaneously mixing the pre-product.
Fremgangsmåten ifølge oppfinnelsen må sees som teknisk fremskritt, da den på grunn av den etterfølgende tilsetning av det skumdempende stoff til det ved varmforstøvnings-tørkning på forhånd fremstilte vaskemiddelforprodukt muliggjør en optimal utnyttelse av fosforsyrepartialesterens skumdempende virkning. Således oppnås også ved forhøyet temperatur av vaskebadet eller ved anvendelse av et mykt vaskevann med en hårdhetsgrad på mindre enn 10°dH allerede ved en tilsetning av ca. 0,2-2 vekt% av fosforsyrepartialester til vaskemidlet en tilfredsstillende skumdempningseffekt, mens under tilsvarende betingelser kan eksempelvis fremgangsmåteproduktet ifølge DAS 1.6l7.l60 ikke hindre overskumming av vaskebadet. Anvendelsen av minst mulige mengder av skumdempende stoff er allerede å anbefale av økonomiske grunner, da fremstillingen av langkjedede fosforsyrepartialestere er kostbar. The method according to the invention must be seen as technical progress, as due to the subsequent addition of the antifoam substance to the pre-produced detergent precursor by hot spray drying, it enables an optimal utilization of the antifoam effect of the phosphoric acid partial ester. This is also achieved at an elevated temperature of the wash bath or by using a soft wash water with a hardness of less than 10°dH already by adding approx. 0.2-2% by weight of phosphoric acid partial esters to the detergent has a satisfactory foam suppression effect, while under similar conditions, for example, the process product according to DAS 1.6l7.l60 cannot prevent overfoaming of the washing bath. The use of the smallest possible amounts of antifoam is already recommended for economic reasons, as the production of long-chain phosphoric acid partial esters is expensive.

For fremstilling■av et varmforstøvet finvaskemiddel som ble anvendt i temperaturområdet til maksimalt 40°C, ble det i første rekke tilberedt en vandig suspensjon av følgende sammensetning:'3,2 deler natriumdodecylbensulfonat, 0,8 deler palmitinfettaminetoksylat med 8 mol etylenoksyd pr. mol, 1,6 deler lauryletersulfat med 2 mol etylenoksyd pr. mol, 0,4 deler karboksymetylcellulose, 9>6 deler pentanatriumtrifos fat, 7 deler For the production of a hot atomized fine detergent which was used in the temperature range up to a maximum of 40°C, an aqueous suspension of the following composition was first prepared: 3.2 parts of sodium dodecylbenesulfonate, 0.8 parts of palmitin fat amine ethoxylate with 8 mol of ethylene oxide per mol, 1.6 parts lauryl ether sulfate with 2 mol ethylene oxide per mol, 0.4 parts carboxymethylcellulose, 9>6 parts pentasodium triphos barrel, 7 parts
tetranatriumdifos fat, 2,6 deler dinatriumdihydrogendifosfat,tetrasodium diphos fat, 2.6 parts disodium dihydrogen diphosphate,
10,8 deler natriumsulfat og 24 deler vann. Etter homogeni-10.8 parts sodium sulfate and 24 parts water. After homogenization
seringen ble denne suspensjon forstøvningstørket i et varm-luftforstøvningstårn"ved 300°C i likestrømsfremgangsmåten. Det dannede forstøvningsprodukt hadde en fuktighet på 8, 2%. Der- sering, this suspension was spray-dried in a hot-air spray tower" at 300°C in the direct current method. The spray product formed had a moisture content of 8.2%. There-
etter ble det på 99 deler av dette forstøvningsprodukt påsprøytet i forstøvningsblandefremgangsmåten 1 del av en etoksylert mono/ dilaurylfos forsyreester, som pr. mol inneholdt laurylalkohol 4 mol etylenoksyd. after that, 1 part of an ethoxylated mono/dilaurylphos acid ester was sprayed onto 99 parts of this atomization product in the atomization mixing method, which per mol contained lauryl alcohol 4 mol ethylene oxide.
Undersøkelsen av skumdannelsen av de ifølge ek-semplene 1-7 fremstilte vaskepulvere i vaskebadet ble utført i en normal husholdningsvaskemaskin. Hertil ble det innført 1,2 kg ikke tilsmusset bomullsvevnad i avsydde strimler på The investigation of the foam formation of the washing powders produced according to examples 1-7 in the washing bath was carried out in a normal household washing machine. In addition, 1.2 kg of unsoiled cotton fabric was introduced in unsewn strips of
40 x 80 cm som ballast i maskinen. Vaskepulverdoseringen ut-40 x 80 cm as ballast in the machine. The detergent dosage out-

Mengden av innløpende vann beløp seg til gjennom-snittlig 20 liter. Vaskehårdheten av det anvendte springvann utgjorde 5°dH. Skumutviklingen som fremkom i løpet av koke-vaskeprosessen ble iakttatt visuelt og registrert i avhengighet av temperaturen. Hertil ble vaskemaskinens frem- og tilbake- The amount of incoming water amounted to an average of 20 litres. The washing hardness of the tap water used was 5°dH. The development of foam that appeared during the boiling-washing process was observed visually and recorded as a function of the temperature. In addition, the washing machine's back and forth
