Description
Die Erfindung betrifft ein Reinigungsmittel, und zwar im besonderen ein sprühgetrocknetes, nichtionogenes Reinigungsmittel, das Seife enthält.The invention relates to a cleaning agent, in particular a spray-dried, nonionic one Detergent containing soap.
Bei der Herstellung sprühgetrockneter Reinigungsmittel, welche ein nichtionogenes Reinigungsmittel als aktive Komponente enthalten, geschieht es häufig, daß das nichtionogene Reinigungsmittel sich im Mischer oder im Vorratsgefäß, welches zur Beschickung des Sprühtrocknungsturmes verwendet wird, abtrennt. Diese Trennung bewirkt, daß das fertige sprühgetrocknete Reinigungsmittel nicht einheitlich ist. Darüber hinaus bewirkt die Inhomogenität der in Phasen getrennten Paste auf ihrem Weg durch die Düsen des Trocknungsturmes die Bildung sehr dichter Massen, welche nur ungenügende Mengen an nichtionogenem Reinigungsmittel enthalten. Durch diesen Mangel wird die notwendige Teilchenexpansion verhindert, so daß schließlich ein Produkt entsteht, welches ein unerwünscht hohes spezifisches Gewicht besitzt.In the manufacture of spray-dried cleaning agents, which use a non-ionic cleaning agent as contain active components, it often happens that the non-ionic cleaning agent is in the mixer or in the storage vessel which is used to charge the spray drying tower. These Separation causes the finished spray-dried detergent to be non-uniform. Furthermore The inhomogeneity of the paste separated into phases causes the formation of very dense masses on their way through the nozzles of the drying tower, which are only insufficient Contains quantities of non-ionic cleaning agents. This deficiency makes the necessary Particle expansion prevented, so that ultimately a product is formed which has an undesirably high specific Owns weight.
Nach der Erfindung ist es möglich, diese Schwierigkeiten durch Beifügung einer kleinen Menge Seife zu dem nichtionogenen Reinigungsmittel zu umgehen.According to the invention it is possible to overcome these difficulties by adding a small amount of soap to the nonionic Bypass detergents.
Die Erfindung bezieht sich auf ein sprühgetrocknetes Reinigungsmittel folgender Zusammensetzung:The invention relates to a spray-dried cleaning agent of the following composition:
Von etwa 5 bis 15% einer Mischung aus einer Verbindung (1), welche die empirische FormelFrom about 5 to 15% of a mixture of a compound (1) having the empirical formula

besitzt und durch Kondensation von Äthylenoxyd mit einer hydrophoben Base, die ihrerseits durch Kondensation von Propylenoxyd mit Propylenglykol gewonnen wurde, entstanden ist, wobei b eine Zahl zwischen 26 und 30 und a + c einen solchen Wert bedeutet, daß das Molekül 40 bis 50% Äthylenoxyd enthält, und einem im Durchschnitt 14 Kohlenstoffatome in dem Alkylradikal besitzenden Polypropylenalkylphenol (2), welches mit Äthylenoxyd kondensiert wurde, um ein Produkt mit durchschnittlich neun Äthylenoxydgruppen zu ergeben, wobei die bevorzugten Mengen von (1) und (2) jeweils etwa 10 und etwa 1 % betragen; von etwa 20 bis 50 %, vorzugsweise etwa 39%, Pentanatriumtripolyphosphat; von etwa 5 bis 15%, vorzugsweise etwa 11 %, Natriumsilikat; von etwa 10 bis 20%, vorzugsweise etwa 17%, andere alkalische anorganische Salze, wie z. B. Natriumcarbonat; und gekennzeichnet durch einen Zusatz von etwa 0,2 bis 2,0% Seife zum Sprühansatz.and has arisen by condensation of ethylene oxide with a hydrophobic base, which in turn was obtained by condensation of propylene oxide with propylene glycol, where b is a number between 26 and 30 and a + c means a value such that the molecule is 40 to 50% ethylene oxide and a polypropylene alkylphenol (2) having an average of 14 carbon atoms in the alkyl radical which has been condensed with ethylene oxide to give a product having an average of nine ethylene oxide groups, the preferred amounts of (1) and (2) being about 10 and about Be 1%; from about 20 to 50%, preferably about 39%, pentasodium tripolyphosphate; from about 5 to 15%, preferably about 11%, sodium silicate; from about 10 to 20%, preferably about 17%, other alkaline inorganic salts, such as e.g. B. sodium carbonate; and characterized by adding about 0.2 to 2.0% soap to the spray formulation.
Das Natriumsilikat besitzt vorzugsweise ein Si O2: Na2 O-Verhältnis von etwa 2,4:1 bis 2,0 : 1.The sodium silicate preferably has an Si O 2 : Na 2 O ratio of about 2.4: 1 to 2.0: 1.
Die Seifen, welche in dem erfindungsgemäßen Reinigungsmittel verwendet werden können, sind Salze einer oder mehrerer gesättigter oder ungesättigter Fettsäuren, welche eine Acylgruppe mit etwa 8 bis 22 Kohlenstoffatomen, und ein Alkalimetallatom, wie z. B. Natrium, enthalten. Es kann sich dabei um die Alkalimetallsalze Sprühgetrocknetes ReinigungsmittelThe soaps which can be used in the detergent according to the invention are salts of a or more saturated or unsaturated fatty acids, which have an acyl group with about 8 to 22 carbon atoms, and an alkali metal atom such as B. sodium. It can be the alkali metal salts Spray-dried detergent

Das erfindungsgemäße Reinigungsmittel kann außerdem auch inerte Zusätze, wie z. B. Natriumsulfat zusammen mit kleinen Mengen von gebräuchlichen Zusätzen für Reinigungsmittel, wie z. B. Farbstoffe und Salze der Carboxymethylcellulose oder der Carboxymethyloxyäthylceliulose enthalten. Vorzugsweise soll das Reinigungsmittel etwa 0,5 % des Natriumsalzes der Carboxymethyloxyäthylcellulose enthalten.The cleaning agent according to the invention can also inert additives, such as. B. sodium sulfate together with small amounts of common additives for cleaning agents, such as B. dyes and Salts of carboxymethyl cellulose or carboxymethyloxyethyl cellulose contain. The cleaning agent should preferably contain approximately 0.5% of the sodium salt of carboxymethyloxyethyl cellulose contain.

Die Paste wird dann in bekannter Weise sprühgetrocknet, wobei ein frei fließendes Pulver mit einem Feuchtigkeitsgehalt unterhalb 10%, vorzugsweise von etwa 4%, und einem spezifischen Gewicht von nicht über 0,4 g/ccm, vorzugsweise von ungefähr 0,3 g/ccm, erhalten wird. Das folgende Beispiel dient zur Erläuterung der vorliegenden Erfindung. Alle Prozentangaben in der Beschreibung und in den Ansprüchen bedeuten Gewichtsprozente.The spray-dried cleaning agent according to the invention can, for. B. be prepared by mixing the components together at about 85 0 C to form an aqueous paste, the water content of the latter being kept so low that the mixture can still be conveyed with the aid of pumps. The paste is then spray-dried in a known manner, whereby a free flowing powder with a moisture content below 10%, preferably of about 4%, and a specific gravity of not more than 0.4 g / ccm, preferably of about 0.3 g / ccm , is obtained. The following example serves to illustrate the present invention. All percentages in the description and in the claims are percentages by weight.
