Abstract
Description
Die Erfindung betrifft feste und flüssige Wasch- und Reinigungsmittel, enthaltend Fettsäurealkylesteralkoxylate mit sehr enger Homologenverteilung als hautfreundliches, wenig schäumendes und umweltverträgliches Tensid mit einem sehr guten Waschvermögen und gutem Löslichkeitsverhalten.The invention relates to solid and liquid detergents and cleaning agents containing Fatty acid alkyl ester alkoxylates with a very narrow homolog distribution as Skin-friendly, low-foaming and environmentally compatible surfactant with one very good washing power and good solubility behavior.
Moderne Wasch- und Reinigungsmittel, sowohl in fester als auch in flüssiger Form, kommen als Formulierungen mit hohen Konzentrationen an Waschaktivsubstanzen in den Handel. Vorteilhaft ist hierbei die Minimierung von Transport-, Lager- und Verpackungskosten, sowie eine verbesserte Handhabung für den Verbraucher. Problematisch für den Hersteller von Flüssigkonzentraten und festen, insbesondere verpreßten Produkten mit hohen Tensidgehalten ist jedoch ein ungünstiges Löseverhalten in wäßriger Flotte.Modern washing and cleaning agents, both in solid and in liquid form, come as formulations with high concentrations of detergent substances in the trade. The minimization of transport, storage and Packaging costs, as well as improved handling for the consumer. Problematic for the manufacturer of liquid concentrates and solid, in particular pressed products with high surfactant contents is an unfavorable one Dissolving behavior in an aqueous liquor.
Es ist bekannt, daß Aniontenside, beispielsweise Alkylsulfate in hohen Konzentrationen, das heißt, in Mengen oberhalb 8 Gew.-%, insbesondere in Kombination mit Niotensiden zu einer starken Gelbildung und damit schlechter Einspülbarkeit in der Waschmaschine führen.It is known that anionic surfactants, for example alkyl sulfates in high Concentrations, that is, in amounts above 8 wt .-%, especially in Combination with nonionic surfactants to form a strong gel and thus worse Can be washed in the washing machine.
Um Gelbildung bei der Herstellung oder Lagerung von Flüssigwaschmittel zu vermeiden und geeignete Viskositäten der Formulierungen zu erreichen, werden häufig nichtoberflächenaktive organische Lösungsmittel zugesetzt. So werden in den Schriften WO 98/00510 und WO 98/00511 nichtwäßrige Flüssigwaschmittel beschrieben, die als Löslichkeitsvermittler annähernd 20 Gew.-% Polyethylenglykole oder Glykolether enthalten. Wünschenswert ist, auf Verbindungen verzichten zu können, die kein oder wenig Waschaktivvermögen zeigen. To prevent gel formation in the manufacture or storage of liquid detergents avoid and achieve suitable viscosities of the formulations often non-surfactant organic solvents added. So be in the documents WO 98/00510 and WO 98/00511 non-aqueous liquid detergents described that as a solubilizer, approximately 20 wt .-% polyethylene glycols or contain glycol ether. It is desirable to avoid connections who show little or no detergent power.
In WO 93/02176 wird ein Verfahren zur Herstellung von festen Wasch- und Reinigungsmitteln mit hohem Schüttgewicht vorgeschlagen, worin man zur Verbesserung des Auflöseverhaltens Strukturbrecher, beispielsweise Polyethylenglykol oder Polypropylenglykol, deren Sulfate und/oder Disulfate, Sulfosuccinate und/oder Sulfosuccinate oder Mischungen aus diesen einsetzt.In WO 93/02176 a method for the production of solid washing and Detergent with a high bulk density proposed, in which one for Improving the dissolution behavior of structure breakers, for example Polyethylene glycol or polypropylene glycol, their sulfates and / or disulfates, Sulfosuccinate and / or sulfosuccinate or mixtures thereof is used.
Die Löslichkeit der festen Wasch- und Reinigungsmittel kann auch durch Erhöhung des Tensidgehaltes, insbesondere durch den Einsatz von nichtionischen Tensiden, wie z.B. ethoxilierten Fettalkoholen verbessert werden. Nachteilig ist ein Verkleben der festen Waschmittelteilchen, wodurch die Rieselfähigkeit und die Einspülbarkeit beeinträchtigt wird.The solubility of solid detergents and cleaning agents can also be increased the surfactant content, especially through the use of non-ionic surfactants, such as. ethoxylated fatty alcohols can be improved. Adhesion is disadvantageous the solid detergent particles, which makes them free-flowing and washable is affected.
Ethoxylierte Fettalkohole in Flüssigkonzentraten tendieren dazu, beim Verdünnen mit Wasser eine Gelphase zu bilden. Andere Tensidsysteme in Wasch- und Reinigungsmittel verleihen dem Mittel zwar eine gute Löslichkeit, zeigen aber eine schlechtere Waschkraft, so daß größere Mengen an Wasch- und Reinigungsmittel eingesetzt werden müssen.Ethoxylated fatty alcohols in liquid concentrates tend to dilute to form a gel phase with water. Other surfactant systems in washing and Detergents give the agent good solubility, but show one poorer washing power, so that larger amounts of detergents and cleaning agents must be used.
Ein weiteres Ziel bei der Herstellung von Wasch- und Reinigungsmitteln ist es, Mittel mit hohen Waschaktivsubstanzgehalten und geringe Schaumbildung zu liefern.Another goal in the manufacture of detergents and cleaning agents is to use detergents with high levels of active detergent and low foaming.

Waschmittel beschrieben, die zur Verbesserung der Löslichkeit als nichtionische
Tenside Fettsäurealkylesteralkoxylate enthalten.

Reinigungsmitteln, enthaltend als anionisches Tensid C8-C22-Alkylsulfate in fester
Form und 3 bis 20 Gew.-%, bezogen auf die C8-C22-Alkylsulfate,
Carbonsäurealkylesteralkoxylate.
In DE-A-195 09 752 wird ein Verfahren zur Herstellung von verpreßten Wasch- und
Reinigungsmittel mit hohem Schüttgewicht beansprucht, wobei als feste
Bestandteile Aniontenside, Buildersubstanzen und Alkalisierungsmittel und als
flüssige Bestandteile Niotenside mit mehr als 50 Gew.-%
Fettsäurealkylesteralkoxylaten, bezogen auf den Niotensidanteil eingesetzt werden.The Japanese patent application Heisei 6-116 599 describes granular detergents which contain fatty acid alkyl ester alkoxylates to improve solubility as nonionic surfactants.
EP-A-0 814 152 describes the production of solid detergents and cleaning agents containing, as an anionic surfactant, C 8 -C 22 alkyl sulfates in solid form and 3 to 20% by weight, based on the C 8 -C 22 alkyl sulfates , Carboxylic acid alkyl ester alkoxylates.

Die in DE-A-195 09 752 und in WO 96/05284 genannten Fettsäurealkylesteralkoxylate können gemäß den dortigen Angaben nach dem in WO 91/15441 und WO 90/13533 beschriebenen Verfahren durch Alkoxylierung von Fettsäureestern in Gegenwart von hydrophobierten Hydrotalciten oder calcinierten Hydrotalcite als Katalysatoren hergestellt werden.Those mentioned in DE-A-195 09 752 and in WO 96/05284 Fatty acid alkyl ester alkoxylates can, according to the information given there, in accordance with Methods described by WO 91/15441 and WO 90/13533 by alkoxylation of Fatty acid esters in the presence of hydrophobicized hydrotalcites or calcined Hydrotalcites can be produced as catalysts.
In US-A-5 220 046 und US-A-5 386 045 wird gezeigt, daß die Alkoxylierung von Fettsäurealkylestern in Gegenwart der Katalysatoren Natriumhydroxid, Natriummethoxid oder Hydrotalciten zu Produkten mit einem hohen Anteil an nicht umgesetztem Fettsäurealkylester und einer relativ breiten Verteilung an Fettsäurealkylesteralkoxylaten führt.US-A-5 220 046 and US-A-5 386 045 show that the alkoxylation of Fatty acid alkyl esters in the presence of the catalysts sodium hydroxide, Sodium methoxide or hydrotalcites to products with a high percentage of not converted fatty acid alkyl ester and a relatively wide distribution Fatty acid alkyl ester alkoxylates leads.
Die Aufgabe der Erfindung lag darin, flüssige und feste Wasch- und Reinigungsmittel zu entwickeln, die eine gute Löslichkeit und geringe Gelbildung, geringe Schaumbildung und gleichzeitig eine verbesserte Waschleistung gegenüber dem Stand der Technik zeigen.The object of the invention was to liquid and solid washing and To develop cleaning agents that have good solubility and low gel formation, low foaming and at the same time improved washing performance show the state of the art.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß man wäßrige oder nicht-wäßrige Wasch- und Reinigungsmittel herstellt, die solche Fettsäurealkylesteralkoxylate enthalten, die im Vergleich zum Stand der Technik eine wesentlich engere Homologenverteilung haben.The object is achieved in that aqueous or non-aqueous Detergents and cleaning agents manufactures such Fatty acid alkyl ester alkoxylates contain compared to the prior art have a much narrower homolog distribution.
Gegenstand der Erfindung sind Wasch- und Reinigungsmittel, die
Fettsäurealkylesteralkoxylate der Formel 1
Wesentlich für die vorliegende Erfindung ist die enge Homologenverteilung der
Alkoxylierungsprodukte wie zuvor definiert. Diese Definition soll im folgenden für
eine Verbindung der Formel 1 mit der maximalen Häufigkeit der -AO-Gruppen von
10
(a = 10) näher erläutert werden. Für diesen Fall soll die Menge der alkoxylierten
analogen Verbindungen, die 7 und weniger als 7 -AO-Gruppen enthalten (a - 3),
weniger als 14 Gew.-% betragen. Umgekehrt soll die Menge der alkoxylierten
Verbindungen mit einem Alkoxylierungsgrad von 13 oder mehr als 13 weniger als
16 Gew.-% betragen.The narrow homolog distribution of the alkoxylation products as defined above is essential for the present invention. This definition is intended in the following for a compound of formula 1 with the maximum frequency of the -AO groups of 10
(a = 10) are explained in more detail. In this case, the amount of the alkoxylated analog compounds which contain 7 and less than 7 -AO groups (a - 3) should be less than 14% by weight. Conversely, the amount of alkoxylated compounds with a degree of alkoxylation of 13 or more than 13 should be less than 16% by weight.
Entsprechendes gilt für die Fettsäurealkytesteralkoxylate mit anderen Zahlen für die maximale Häufigkeit der -AO-Gruppen. Die so definierte Homologenverteilung ist deutlich enger als bei den Fettsäurealkylesteroxalkylaten, wie sie bei den Produkten nach dem in WO 90/13533 und WO 91/15441 beschriebenen Verfahren erhalten werden und die hier definierten Verbindungen mit der engeren Homologenverteilung zeichnen sich aus durch eine wesentlich bessere Waschleistung sowie eine geringe Gelbildung beim Lösevorgang. Die so definierten Verbindungen der Formel 1 sind im folgenden als "narrow range" Fettsäurealkylesteralkoxylate bezeichnet.The same applies to the fatty acid alkoxylates with different numbers for the maximum frequency of the -AO groups. The homolog distribution thus defined is significantly narrower than that of the fatty acid alkyl ester oxyalkylates, as is the case with the products obtained by the method described in WO 90/13533 and WO 91/15441 and the connections defined here with the narrower homolog distribution are characterized by a much better washing performance and a low Gel formation during the dissolving process.

Teilneutralisierte Ca-Salze von mit C8-C30-Alkylresten substituierten
Bernsteinsäurehalbestern (EP-A-657 410);
Alkali- und Erdalkalimetallverbindungen aus der Gruppe der Hydroxide, Oxide und
Alkoholate (EP-A-0 335 295);
