Fra britisk patentskrift nr. 807.640 kendes vaskemiddelpartikler indeholdende ikke-ionogene tensider og findelt silica.British Patent Specification No. 807,640 discloses detergent particles containing nonionic surfactants and finely divided silica.
Ifølge den kendte teknik har man hidtil højst tilsat 5% silicapartik-ler til en blanding af ikke-ionogent overfladeaktivt middel og et andet bæremateriale. I forbindelse med den kendte teknik er silica blevet anvendt som et middel til modvirkning af sammenbagning og ikke som en bærer per se for det ikke-ionogene overfladeaktive middel. Man har ikke tidligere foreslået nogen forblanding med et højt indhold af ikke-ionogent overfladeaktivt middel baseret på pyrogene siliciumdioxidpartikler som bærer for det ikke-ionogene overfladeaktive middel eller forblandinger, som udelukkende indeholder ikke-ionogent overfladeaktivt middel og silica.According to the prior art, at most 5% silica particles have been added to a mixture of nonionic surfactant and other carrier material. In the prior art, silica has been used as an agent for counteracting baking and not as a carrier per se for the nonionic surfactant. No high-content non-ionic surfactant premix based on pyrogenic silica particles bearing the nonionic surfactant or premixtures containing exclusively nonionic surfactant and silica has been previously proposed.
Den foreliggende opfindelse er en hidtil ukendt og overraskende gunstig forblanding, som kun indeholder ikke-ionogent overfladeaktivt middel og pyrogent mikrofindelt silica. Opfindelsen ligger nemlig i, at den i krav 1 anførte type siliciumdioxid, dvs. pyrogent silicium= dioxid, kan medføre store mængder på 75-85 vægt% flydende ikke-ionogent overfladeaktivt middel og dog forblive et frit-strømmende produkt, som er velegnet til senere tilsætning til sprøjtetørrede detergentpulvere .The present invention is a novel and surprisingly favorable premix containing only nonionic surfactant and pyrogenic microfine silica. The invention is that the type of silicon dioxide mentioned in claim 1, i.e. pyrogenic silicon = dioxide can cause large amounts of 75-85% by weight of liquid nonionic surfactant and yet remain a free-flowing product suitable for later addition to spray-dried detergent powders.
De mest almindeligt anvendte overfladeaktive midler i kraftigt virkende detergentprodukter er anioniske forbindelser med rensende egenskaber. Typiske eksempler på disse anioniske forbindelser er de højere alkylenkemede aromatiske sulfonater, såsom de højere alkyl= benzensulfonater. Disse syntetiske detergenter er meget virksomme til fjernelse af snavs fra tekstilstoffer, når de anvendes i forbindelse med phosphatbuildere, der har til opgave at "blødgøre" vandet, der skal anvendes, og at tilvejebringe rensende virkning. For tiden er der imidlertid en kraftig polemik vedrørende virkningen af at anvende phosphatforbindelser i detergentpræparater på grund af deres påståede forårsagelse af eutrofieringsprocessen i søer, floder og vandløb. Selv om eutrofieringsprocessen, hvori en usædvanlig stor stigning af planteliv promulgeres i naturlige vandmasser, ikke forstås fuldstændig, antages det at phosphatforbindeiserne, som findes i detergentholdigt spildvand, er en væsentlig faktor til fremme af dette fænomen.The most commonly used surfactants in powerful detergent products are anionic compounds with scavenging properties. Typical examples of these anionic compounds are the higher alkylene chemically aromatic sulfonates, such as the higher alkyl = benzenesulfonates. These synthetic detergents are very effective in removing dirt from textile fabrics when used in conjunction with phosphate builders whose job is to "soften" the water to be used and to provide a purifying effect. Currently, however, there is a strong controversy regarding the effect of using phosphate compounds in detergent preparations due to their alleged cause of the eutrophication process in lakes, rivers and streams. Although the eutrophication process in which an unusually large increase in plant life is promoted in natural water masses is not fully understood, it is believed that the phosphate compounds found in detergent-containing wastewater are a major factor in promoting this phenomenon.

Selv om ikke-ionogene overfladeaktive midler ikke er så virksomme som anioniske overflademidler i nærværelse af store mængder phosphat= buildere,har det vist sig, at når phosphatindholdet i et detergentpræparat reduceres væsentligt,viser de ikke-ionogene overfladeaktive midler sig at tilvejebringe rensende egenskaber, som er bedre end anioniske forbindelsers i det samme præparat med reduceret phosphat= indhold. Ikke-ionogene overfladeaktive midlers rensningsvirkning påvirkes tilsyneladende langt mindre af vands hårdhed end rensningsvirkningen af de almindeligt anvendte anioniske overfladeaktive midler. I tilfælde af,at phosphatbuildeme fjernes helt eller delvist fra detergenterne,vil inkorporeringen af større og større mængder ikke-ionogene overfladeaktive midler i detergentprodukter blive meget ønskelig.Although nonionic surfactants are not as effective as anionic surfactants in the presence of large amounts of phosphate builders, it has been found that when the phosphate content of a detergent composition is substantially reduced, the nonionic surfactants are found to provide purifying properties. which is better than those of anionic compounds in the same reduced phosphate = composition. The purifying effect of nonionic surfactants appears to be far less affected by water hardness than the purifying action of the commonly used anionic surfactants. In the event that the phosphate builders are completely or partially removed from the detergents, the incorporation of larger and larger amounts of nonionic surfactants into detergent products will be highly desirable.
For tiden tilsættes små mængder ikke-ionogene overfladeaktive midler til detergentprodukter, først og fremmest for at formindske den under vaskningen dannede skummængde. De mest almindeligt anvendte ikke-ionogene overfladeaktive midler er langkædede alkoholer ethoxyleret med ethylenoxid. Den Ikke-ionogene ethoxamer der anvendes, har typisk en alkylkæde med 12-18 carbonatomer og et gennemsnit på 10-19 ethylenoxidenheder. Området for ethylenoxidindhold, som tilvejebringer den største rensevirkning i disse overfladeaktive midler, resulterer sædvanligvis i et ikke-ionogent materiale, som er en viskos væske ved stuetemperatur og derfor uegnet til direkte tilsætning til det tørre detergentpulver. Det har imidlertid vist sig, at når en væsentlig mængde, typisk over ca. 5 vægt#, ikke-ionogent overfladeaktivt middel inkorporeres i detergentopslemningen før sprøjtetørring, opstår der et væsentligt luftforureningsproblem. Dette problem, kendt i industrien som "pluming", ytrer sigsom en tæt sort røg, der strømmer ud fra sprøjtetåmet.Currently, small amounts of nonionic surfactants are added to detergent products, primarily to reduce the amount of foam formed during washing. The most commonly used nonionic surfactants are long chain alcohols ethoxylated with ethylene oxide. The Nonionic Ethoxamer used typically has an alkyl chain of 12-18 carbon atoms and an average of 10-19 ethylene oxide units. The range of ethylene oxide content which provides the greatest purification effect in these surfactants usually results in a nonionic material which is a viscous liquid at room temperature and therefore unsuitable for direct addition to the dry detergent powder. However, it has been found that when a substantial amount, typically above ca. 5% by weight, nonionic surfactant is incorporated into the detergent slurry prior to spray drying, a significant air pollution problem occurs. This problem, known in the industry as "pluming," expresses itself as a dense black smoke flowing from the spray.
Formålet med den foreliggende opfindelse er at tilvejebringe ikke-ionogene overfladeaktive midler på tør frit-strømmende partikelform, således at de senere kan tilsættes til sprøjtetørrede detergentprodukter og derved væsentligt forøge indholdet af ikke-ionogent overfladeaktivt middel i detergentslutproduktet. At gøre indholdet af ikke-ionogent overfladeaktivt middel maksimalt i det fritstrømmende pulver, der kan tilsættes senere, og valget af de specielt egnede 4 142703 bærere for de ikke-ionogene materialer, er vigtige yderligere aspekter ved opfindelsen.The object of the present invention is to provide non-ionic surfactants in dry free-flowing particulate form so that they can later be added to spray-dried detergent products, thereby substantially increasing the content of nonionic surfactant in the detergent final product. Maximizing the content of nonionic surfactant in the free-flowing powder that can be added later and the choice of the particularly suitable carriers for the nonionic materials are important further aspects of the invention.
En forblanding ifølge opfindelsen, der består af 75-85% ikke-ionogent overfladeaktivt middel og 15-25% pyrogent mikrofindelt silica, er meget velegnet til senere tilsætning til sprøjtetørret detergentpulver, for i væsentlig grad at forøge indholdet af ikke-ionogent overfladeaktivt middel i detergentslutproduktet. For at opnå en optimal postadditiv-blanding til sprøjtetørrede detergentprodukter er det ønskeligt at gøre mængden af ikke-ionogent overfladeaktivt middel på den valgte bærer maksimal og ligeledes at vælge bærere, som bidrager til detergentproduktets effektivitet. En forblanding ifølge opfindelsen kan efter tilsætning til detergentproduktet bidrage heri med funktionelle egenskaber.A premix of the invention, consisting of 75-85% nonionic surfactant and 15-25% pyrogenic microfine silica, is very suitable for later addition to spray-dried detergent powder, to substantially increase the content of nonionic surfactant in detergent end. In order to obtain an optimum post-additive mixture for spray-dried detergent products, it is desirable to maximize the amount of nonionic surfactant on the selected carrier and also to select carriers that contribute to the detergent product's effectiveness. A premix according to the invention, after addition to the detergent product, can contribute herein with functional properties.
Pyrogent mikrofindelt silica er i stand til at bære en stor mængde på op til 85 vægt% ikke-ionogent overfladeaktivt middel uden at miste evnen til at strømme frit. Da mikrofindelt siliciumdioxid anvendes som et middel ipod sammenbagning i nogle detergentpræparater, bevirker anvendelsen heraf som bærer for et flydende ikke-ionogent stof en samtidig modvirkning mod sammenbagning såvel som et højere indhold af ikke-ionogent stof i detergentpræparatet, som det til sidst kombineres med.Pyrogenic microfine silica is capable of carrying a large amount of up to 85% by weight of nonionic surfactant without losing the ability to flow freely. Since microfine silica is used as a means of ipod baking in some detergent compositions, its use as a carrier for a liquid nonionic substance causes a simultaneous counteracting to baking as well as a higher content of nonionic substance in the detergent composition with which it is eventually combined.
I eksemplet er det anvendte ikke-ionogene overfladeaktive middel en ethoxyleret langkædet alkohol med en kæde på 12-16 carbonato-mer og 10-12 ethylenoxidenheder. En egnet ethoxamer kan fås fra Shell Chemical Company under handelsnavnet "NEODOL" 45-11. "NEODOL" 45-11 er ifølge fremstillerne en 14-15 carbonkæde ethoxyleret fedtalkohol med gennemsnitligt 11 ethylenoxidenheder. Det partikelformede siliciumdioxidmateriale, der blev anvendt, fås under handelsnavnet "Cab-O-Sil" kvalitet EH-5 fra Cabot Company. "Cab-O-Sil" er et siliciumdioxid med submikroskopisk partikelstørrelse, fremstillet ved dampfasehydrolyse af siliciumtetrachlorid ved 1100°C. Alle forsøg blev foretaget ved stuetemperatur og atmosfæretryk .In the example, the nonionic surfactant used is an ethoxylated long chain alcohol having a chain of 12-16 carbon atoms and 10-12 ethylene oxide units. A suitable ethoxamer can be obtained from Shell Chemical Company under the trade name "NEODOL" 45-11. "NEODOL" 45-11 is, according to the manufacturers, a 14-15 carbon chain ethoxylated fatty alcohol with an average of 11 ethylene oxide units. The particulate silica used was obtained under the trade name "Cab-O-Sil" grade EH-5 from Cabot Company. "Cab-O-Sil" is a submicroscopic particle size silica produced by vapor phase hydrolysis of silicon tetrachloride at 1100 ° C. All experiments were performed at room temperature and atmospheric pressure.

Eksempel 50 g smeltet ikke-ionogent overfladeaktivt middel blev opvarmet til en temperatur lidt over stuetemperatur,til det var klart, og derpå sprøjtet på 10 g colloidt pyrogent siliciumdioxid. Den resulterende blanding var et fritstrømmende pulver med 83,3 vægt$ ikke-ionogent materiale. Der blev anvendt følgende teknik.Example 50 g of molten nonionic surfactant was heated to a temperature slightly above room temperature until clear, then sprayed on 10 g of colloidal pyrogenic silica. The resulting mixture was a free flowing powder with 83.3% nonionic material. The following technique was used.
1) Det flydende ikke-ionogene materiale blev sprøjtet på en labora-torieskive, indeholdende siliciumdioxidbæreren og blandet med en spatel til frembringelse af et fritstrømmende pulver.1) The liquid nonionic material was sprayed onto a laboratory disc containing the silica carrier and mixed with a spatula to produce a free flowing powder.
2) Det flydende ikke-ionogene overfladeaktive middel blev sprøjtet i en luftfyldt plastpose, hvori siliciumdioxidpartiklerne blev suspenderet ved hjælp af luftstrømme.2) The liquid nonionic surfactant was sprayed in an air-filled plastic bag in which the silica particles were suspended by air currents.
3) Det flydende ikke-ionogene overfladeaktive middel blev sprøjtet i en dobbeltkapslet rotationsblander, indeholdende siliciumdio= xidpartiklerne.3) The liquid nonionic surfactant was sprayed in a double-encapsulated rotary mixer containing the silica particles.
Størkningsmekanismen fra de foregående fremgangsmåder antages at omfatte belægningen af partiklerne af det flydende overfladeaktive middel med de mikroskopiske siliciumdioxidpartikler frem for absorptionen eller adsorptionen af væsken ved hjælp af partiklerne.The solidification mechanism of the foregoing processes is believed to comprise coating the particles of the liquid surfactant with the microscopic silica particles rather than the absorption or adsorption of the liquid by the particles.
Det ved hjælp af den foregående metode dannede frit-strømmende pulver kan senere tilsættes til sprøjtetørrede detergentpulvere eller detergentbuildere,og andre detergentbestanddele kan tilsættes til det ikke-ionogene pulver til fremstilling af et færdigt detergentprodukt.The free-flowing powder formed by the foregoing method can later be added to spray-dried detergent powders or detergent builders, and other detergent ingredients can be added to the nonionic powder to produce a finished detergent product.
Et eksempel på den sidstnævnte fremgangsmåde er først at fremstille et fritstrømmende pulver, bestående af 250,0 g af et flydende ikke-ionogent overfladeaktivt middel og 50,0 g siliciumdioxidbærer (83,3 vægt$ ikke-ionogent). Til denne blanding blev der tilsat 100,0 g natriumsalte af (NTA) og 100,0 g natriumcitrat og blandet til fremstilling af et færdigt detergentprodukt med følgende tilnærmelsesvise sammensætning:An example of the latter process is to first prepare a free-flowing powder consisting of 250.0 g of a liquid nonionic surfactant and 50.0 g of silica carrier (83.3% by weight nonionic). To this mixture was added 100.0 g of sodium salts of (NTA) and 100.0 g of sodium citrate and mixed to prepare a finished detergent product of the following approximate composition:
