Die vorliegende Erfindung betrifft Waschmittel mit gedrücktem Schaum und guter Reinigungswirkung.The present invention relates to compressed foam detergents having good detergency.

Stark schäumende Waschmittel, wie die hoch wirksamen, anionische Reinigungsmittel enthaltenden Waschmittel, entwickeln bei ihrer Verwendung in Waschmaschinen mit horizontal gelagerter Trommel nicht ihr volles Reinigungsvermögen, weil der Schaum die Bewegung der zu waschenden Kleidungsstücke zu stark dämpft.High-foaming detergents, such as those containing highly effective anionic detergents Detergents develop when they are used in washing machines with a horizontally mounted drum not their full cleaning power because the foam causes the movement of the clothes to be washed dampens too much.

Es wurden nun schon Waschmittel aus nicht ionischen Reinigungsmitteln, wie den hochmolekularen Äthern und Estern von Äthylen- und Propylenoxydkondensationsprodukten, entwickelt, die reinigungsaktiv sind und dabei eine relativ !geringe Schaumkraft besitzen. Diese Waschmittel sind jedoch hinsichtlich ihrer Waschwirksämikeit bei der Reinigung stark verschmutzter Baumwollgewelbe den sehr reinigungsaktiven anionischen synthetischen Waschmitteln nicht gleichwertig.Detergents made from non-ionic detergents, such as high-molecular detergents, have now been made Ethers and esters of ethylene and propylene oxide condensation products, which are active in cleaning and have a relatively low foaming power. However, these detergents are with regard to their washing effectiveness when cleaning heavily soiled cotton cloth the very active cleaning anionic synthetic detergents not equivalent.

Es wurden auch schon Schaumdrücker mit den reinigungsaktiven Substanzen zusammen verwendet. Die reinigungsaktiven anionischen Sulfate und Sulfonate, wie die wasserlöslichen Salze der Schwefelsäureester höherer aliphatischer Alkohole und die wasserlöslichen Salze von alkylierten Benzolsulfonsäuren, sind jedoch sehr starke Schäumer, und ein Mittel, das alle gewünschten Eigenschaften, wie Wirtschaftlichkeit und wirksame und dauernde Schaumdrückung bei niedriger Konzentration, besitzt und das Reinigungsvermögen nicht beeinträchtigt, ist bisher noch nidht gefunden worden.Foam presses have also been used together with the active cleaning substances. The cleaning-active anionic sulfates and sulfonates, such as the water-soluble salts of sulfuric acid esters higher aliphatic alcohols and the water-soluble salts of alkylated benzenesulfonic acids, however, are very strong foaming agents, and a means that has all the desired properties, such as Economics and effective and permanent foam suppression at low concentration and the detergency is not impaired, has not yet been found.

Aus Lindner, »Textilhüfsmittel und Waschrohstoffe«, S. 453, zweiter Absatz, und UhI, »Fette und Seifen«, 53, S. 84 bis 88 (1951), ist zwar bekannt, daß das Schaumvermögen von organischen Schwefelsäurereaktionsprodukten durch den Zusatz von Seifen verschlechtert wird. Diese Literaturstellen konnten aber zu keiner Lösung des oben aufgezeigten Problems führen, da den darin enthaltenen Angaben zu entnehmen ist, daß die Verminderung der Schaumkraft von Seifen und synthetischen waschaktiven Substanzen in solchen Gemischen am größten, ist, die viel Seife neben wenig synthetischen kapillaraktiven Substanzen enthalten, und derartige Mischungen als die günstigsten Kombinationen bezeichnet werden, während die Waschmittel, auf die sich die vorliegende Erfindung bezieht, vorwiegend -aus solchen synthetischen kapillaraktiven Substanzen bestehen.From Lindner, "Textile Auxiliaries and Washing Raw Materials", P. 453, second paragraph, and UhI, "Fette und Seifen", 53, pp. 84 to 88 (1951), is known that the foaming power of organic sulfuric acid reaction products by the addition is worsened by soaps. However, these references could not provide a solution to the above Problem lead, since the information contained therein can be seen that the reduction in foam power of soaps and synthetic detergent substances in such mixtures is greatest, the contain a lot of soap in addition to few synthetic capillary-active substances, and such mixtures as the most favorable combinations are referred to as the detergent to which the present one is based Invention relates, predominantly consist of such synthetic capillary-active substances.

Es wurde nun gefunden, daß die Schaumkraft von stark wirksamen Waschmitteln, wie beispielsweise den in der USA.-Patentschrift 2 486 921 beschriebenen, die wasserlösliche synthetische anionische Waschmittel mit gedrücktem SchaumIt has now been found that the foaming power of highly effective detergents, such as those described in U.S. Patent 2,486,921, the water-soluble synthetic anionic Detergent with squeezed foam

Es wurde gefunden, daß ein Gemisch von Fettsäuren bzw. Fettsäuresalzen der angegebenen Art ein sehr viel wirksamerer Schaumdrücker ist als eine einzelne Verbindung und daß die Komplexität des Gemisches, in dem wenigstens drei und vorzugsweise vier oder mehr verschiedene Fettsäuren vorhanden sind, von wesentlicher Bedeutung ist.It has been found that a mixture of fatty acids or fatty acid salts of the specified type is much more effective foam suppressor than a single compound and that the complexity of the mixture, in which at least three and preferably four or more different fatty acids are present is essential.

Für die Herstellung der Schaumdrücker der vorliegenden Erfindung werden, wie schon ausgeführt, Fettsäuregemische verwendet, und zwar insbesondere gesättigte Fettsäuren mit 16 oder mehr Kohlenstoffatomen in dem Acylrest.For making the foam pusher of the present In the invention, as already stated, fatty acid mixtures are used, in particular saturated fatty acids having 16 or more carbon atoms in the acyl radical.

Die Anwesenheit anderer Fettsäuren, wie gesättigter C14-Säure (Myristinsäure) und ungesättigter Säuren (Olein- und Linoleinsäure), ist jedoch nicht nachteilig und kann sogar vorteilhaft sein, vorausgesetzt, daß das Gemisch im übrigen aus wenigstens 50% gesättigten Fettsäuren mit 16 oder mehr Kohlenstoffatomen besteht und daß wenigstens 5% der gesättigten Fettsäuren wenigstens 20 Kohlenstoffätome enthalten. The presence of other fatty acids, such as saturated C 14 acid (myristic acid) and unsaturated acids (oleic and linoleic acid), however, is not disadvantageous and can even be advantageous, provided that the mixture also consists of at least 50% saturated fatty acids with 16 or consists of more carbon atoms and that at least 5% of the saturated fatty acids contain at least 20 carbon atoms.

Die Zusammensetzung der Schaumdrücker der vorliegenden Erfindung können in den im folgenden angegebenen Grenzen variieren:The composition of the suds suppressor of the present invention can be in the following specified limits vary:

Linoleinsäure ...·.. 0 bis 10% .Linoleic acid ... · .. 0 to 10%.

Besonders wertvolle Schaumdrücker sind allgemein Gemische gemäß der vorliegenden Erfindung, die etwa 5 bis 15% Myristinsäure, etwa 25 bis 35% Palmitinsäure, etwa 15 bis 25% Stearinsäure, etwa ,20 bis 30% Arachinsäure und etwa 10 bis 20% Behensäure enthalten.Particularly valuable foam depressants are generally mixtures according to the present invention, the about 5 to 15% myristic acid, about 25 to 35% palmitic acid, about 15 to 25% stearic acid, about Contain 20 to 30% arachidic acid and about 10 to 20% behenic acid.

Statt eines Gemisches von Fettsäuren kann auch ein Gemisch von Alkaliseifen der Fettsäuren oder ein Gemisch von Fettsäuren und Fettsäureseifen verwendet werden. Es ist sogar erwünscht, daß die normale Alkalinität solcher stark wirksamen Waschmittel hoch genug ist, um Fettsäuren zu Seife umzuwandeln; und in Waschlaugen aus den Waschmitteln der vorliegenden Erfindung können die Fettsäuren im wesentlichen vollständig in Form der Alkaliseifen vorliegen.Instead of a mixture of fatty acids, a mixture of alkali soaps of the fatty acids or a Mixture of fatty acids and fatty acid soaps can be used. It is even desirable that the normal The alkalinity of such high performance detergents is high enough to convert fatty acids to soap; and in detergents from the detergents of the In the present invention, the fatty acids can be essentially completely in the form of the alkali soaps are present.

Die Waschmittel der vorliegenden Erfindung können hergestellt werden, indem man das Fettsäureoder Seifengemisch dem Produkt, bevor es seine endgültige Form, wie Flocken, Granalien, Pulver usw., erhält, zusetzt. Das Waschmittel kann aber auch in seiner endgültigen Form mit dem Fettsäuregemisch besprüht werden.The detergents of the present invention can be prepared by using the fatty acid or Soap mix the product before it's final Form, such as flakes, granules, powder, etc., is added. The detergent can also be used in its final shape can be sprayed with the fatty acid mixture.

Die Wascheigenschaften des Endproduktes werden durch das Verfahren zu seiner Herstellung nicht wesentlich beeinflußt, und bezüglich der Reinigungswirkung und Schäumkraft der Waschlaugen ist es unerheblich, ob die Fettsäuren, Seifen oder Gemische von Fettsäuren und Seifen homogen in jeder der Partikeln verteilt sind oder auf die fertigen Partikeln aufgesprüht wurden.The washing properties of the end product are not affected by the process for its manufacture significantly influenced, and with regard to the cleaning effect and foaming power of the washing liquors it is It does not matter whether the fatty acids, soaps or mixtures of fatty acids and soaps are homogeneous in each of the Particles are distributed or have been sprayed onto the finished particles.

Waschmittel, deren Schaumkraft durch die Schaumdrücker der vorliegenden Erfindung herabgesetzt wird, sind beispielsweise die in den USA.-Patentschriften 2 486 921 und 2 486 922 beschriebenen, die als aktive Bestandteile ein Salz eines anionischen synthetischen Sulfats oder Sulfonate mit 8 bis 18 Kohlenstoffatomen im Alkylrest und Alkalitripolyphosphat enthalten, wobei das Verhältnis desTripolyphosphats zu der synthetischen waschaktiven Substanz bei den heiß getrockneten Produkten der erwähnten USA.-Patentschrift 2 486 922 in dem Bereich von 1:1 bis 5:1 liegt und das synthetische anionische Sulfat oder Sulfonat vorzugsweise in einer Menge von etwa 10 bis etwa 40 % des fertigen Waschmittels anwesend ist. Beispiele für die synthetischen waschaktiven Substanzen sind die Alkylsulfäte, insbesondere die Sulfatierungsprodukte der höheren,Detergents whose foaming power is reduced by the foam depressors of the present invention are, for example, those described in U.S. Patents 2,486,921 and 2,486,922, U.S. Patent Nos. 2,486,921 and 2,486,922 as active ingredients, a salt of an anionic synthetic sulfate or sulfonate with 8 to Contains 18 carbon atoms in the alkyl radical and alkali metal tripolyphosphate, the ratio of the tripolyphosphate to the synthetic detergent substance in the hot-dried products of the aforementioned U.S. Patent 2,486,922 ranges from 1: 1 to 5: 1 and the synthetic anionic sulfate or sulfonate preferably in an amount of about 10 to about 40% of the finished detergent is present. Examples of the synthetic detergent substances are the alkyl sulfates, in particular the sulfation products of the higher,

Die verwendete Menge an Schaumdrückern variiert mit den für das Endprodukt erwünschten Eigenschaften. Gewöhnlich wird jedoch die Anwesenheit von etwa 3 bis etwa 6% des Gemisches von Verbindungen, berechnet als Fettsäure und bezogen auf das Gesamtprodukt, bevorzugt. Allgemein kann das Verhältnis von Fettsäuregemisch zu aktivem anionischem synthetischem waschaktivem Material von 0,1 :1 bis 1:1 variieren.The amount of suds suppressor used will vary with the properties desired in the final product. Usually, however, the presence of from about 3 to about 6% of the mixture of compounds calculated as fatty acid and based on the total product, preferred. In general, the relationship can from fatty acid mixture to active anionic synthetic detergent material from 0.1: 1 to Vary 1: 1.

Die Anwendung der vorliegenden Erfindung soll im folgenden an Hand von Beispielen näher erläutert werden. Teile beziehen sich auf das Gewicht.The application of the present invention is to be explained in more detail below with the aid of examples will. Parts are by weight.

Beispiel 1example 1

Zu 97 Teilen eines granulären Gemisches aus etwa 18 Teilen Natriumalkylbenzolsulfonat, dessen Alkylreste im Mittel 12 Kohlenstoffatome enthalten und von Polypropylen abgeleitet sind, etwa 48 Teilen Natriumfcripolyphosphat, etwa 6 Teilen fester Silicate ' und etwa 28 Teilen an anderen Bestandteilen, von denen der größte Teil Wasser und Natriumsulfat war, wurden 3 Teile eines handelsüblichen Fettsäuregemisches aus hydriertem Fischöl zugesetzt, das etwa die folgende Zusammensetzung hatte:To 97 parts of a granular mixture of about 18 parts of sodium alkylbenzenesulfonate, its alkyl radicals contains an average of 12 carbon atoms and is derived from polypropylene, about 48 parts Sodium fripolyphosphate, about 6 parts of solid silicates and about 28 parts of other ingredients, of most of which was water and sodium sulfate, became 3 parts of a commercially available fatty acid mixture from hydrogenated fish oil added, which had approximately the following composition:

Myristinsäure 8 %Myristic acid 8%

Palmitinsäure 29 %Palmitic acid 29%

Stearinsäure 18 %Stearic acid 18%

Arachinsäure 26 %Arachidic acid 26%

Behensäure 17 %Behenic acid 17%

Oleinsäure 2%Oleic acid 2%

Das erhaltene Produkt wurde in Wasser gelöst, so daß eine etwa 0,4%ige Lösung entstand, die zum Waschen von verschmutztem Baumwollgewebe bei normale Waschbedingungen in einer Waschmaschine mit horizontal gelagerter rotierbarer Trommel verwendet wurde. Die Schaumkraft der Waschmittellösung war unterdrückt, während die Reinigungswirkung ausgezeichnet war. The product obtained was dissolved in water, so that an approximately 0.4% solution resulted, which for Washing of soiled cotton fabrics under normal washing conditions in a washing machine was used with the rotatable drum supported horizontally. The foaming power of the detergent solution was suppressed while the cleaning effect was excellent.

Bei vergleichbaren Bedingungen schäumte eine entsprechende Lösung von Waschmitteln, denen keinUnder comparable conditions, a corresponding solution of detergents foamed, which none

Fettsäuregemisch zugesetzt war, so stark, daß die Rühr- oder Umwälzwirkung während des Waschens so stark beeinträchtigt war, daß die Waschwirkung unbefriedigend war.Fatty acid mixture was added so strong that the stirring or circulating effect during washing was so impaired that the detergency was unsatisfactory.

Stearinsäure 41 %Stearic acid 41%

Arachinsäure 5,2 %Arachidic acid 5.2%

Behensäure 3,4 %Behenic acid 3.4%

Oleinsäure,· 1,8%Oleic acid, 1.8%

Wenn dieses Produkt in den normalerweise für eine Waschmittellösung für eine Waschmaschine mit rotierbarer Trommel verwendeten Konzentrationen in Wasser gelöst wurde, so wurde eine ausgezeichnete Waschwirkung beobachtet, während die Waschlauge nicht so stark schäumte, daß das Bewegen der Gewebe während des Betriebs der Maschine wesentlieh gehindert war.When using this product in the normally for a detergent solution for a washing machine rotatable drum used concentrations was dissolved in water, so it was an excellent one Washing effect observed while the wash liquor did not foam so much that moving the Tissue was substantially hindered during the operation of the machine.

Bei vergleichbaren Bedingungen ergab das gleiche Waschmittel, dem kein Fettsäuregemisch zugesetzt war, ein großes Schaumvolumen, durch das das für eine gute Reinigung erforderliche Umwälzen der Wäsche gehindert wurde.Under comparable conditions, the result was the same detergent to which no fatty acid mixture was added was, a large volume of foam, through which the circulation required for good cleaning of the Laundry was prevented.

Beispiel 4Example 4

Zu 93,5 Teilen des gemäß Beispiel 3 verwendeten Waschmittels wurden 6,5 Teile des folgenden Fettsäuregemisches zugesetzt:To 93.5 parts of the detergent used according to Example 3 were 6.5 parts of the following fatty acid mixture added:

Myristinsäure 1,6 %Myristic acid 1.6%

Palmitinsäure 32,7%Palmitic acid 32.7%

Stearinsäure 27,9%Stearic acid 27.9%

Arachinsäure '. 5,2 %Arachidic acid '. 5.2%

Behensäure 3,4%Behenic acid 3.4%

Es wurden allgemein die gleichen Ergebnisse beobachtet wie im Beispiel 3, d. h., das Waschmittel dieses Beispiels zeigte bei Verwendung in einer Waschmaschine mit rotierender Trommel ausgezeichnete Waschwirkung bei gedrücktem Schaum.The same results were generally observed as in example 3, i.e. that is, the detergent of this example showed when used in a washing machine with rotating drum excellent washing effect with squeezed foam.

Beispiel 5Example 5

Eine wäßrige Aufschlämmung, die etwa 16 Teile Natriumalkylbenzolsulfonat der im Beispiel 1 verwendeten Art, 3 Teile des im Beispiel 1 verwendeten Fettsäuregemisches, 45,6 Teile Natriumtripolyphosphat und 10 Teile feste Silicate enthielt, wurde sprühgetrocknet, wobei ein Produkt mit geringer Schaumkraft, jedoch starkem Reinigungsvermögen erhalten wurde.An aqueous slurry containing about 16 parts of the sodium alkylbenzenesulfonate of Example 1 used Art, 3 parts of the fatty acid mixture used in Example 1, 45.6 parts of sodium tripolyphosphate and 10 parts of solid silicates was spray-dried to give a product with low foaming power, however, strong detergency was obtained.

Die Schaumdrücker der vorliegenden Erfindung sind nicht nur in Waschmitteln, sondern auch in anderen Oberflächen- und reinigungsaktiven Mitteln verwendbar. In Reinigungsmitteln für automatische Geschirrspülmaschinen beispielsweise hat eine geringe Menge eines anionischen Reinigungs- oder Netzmittels eine vorteilhafte Wirkung auf die Entfernung von Flecken und die Filmbildung. Jedoch bildet sich durch das heftige Bewegen während des Betriebs der Geschirrspülmaschine selbst bei Verwendung von geringen Mengen solcher Verbindunr gen zuviel Schaum. Es wurde nun gefunden, daß durch die hier beschriebenen Schaumdrücker die durch die Anwesenheit anionischer Verbindungen der angegebenen Art bewirkte Schaumbildung auch in solchen Mitteln wirksam unterdrückt wird.The suds suppressors of the present invention are not only in detergents but others as well Surface and cleaning agents can be used. In detergents for automatic Dishwashers, for example, has a small amount of an anionic detergent or detergent Wetting agent has a beneficial effect on stain removal and film formation.
