Description

Unter Zwei-Komponenten-Waschmitteln versteht man aus zwei getrennt hergestellten und gelagerten Waschmittelbestandteilen bestehende Zubereitungen, die erst unmittelbar vor bzw. zu Beginn des Waschprozesses miteinander vereinigt werden. Die vorliegende Erfindung betrifft ein solches Mittel, in dem die eine Komponente als ein Fettsäuren sowie weitere Tenside enthaltendes Flüssigkonzentrat vorliegt und die andere Komponente das zur,Seifenbildung benötigte Alkali enthält.Two-component detergents are understood to mean preparations consisting of two separately produced and stored detergent constituents which are only combined with one another immediately before or at the start of the washing process. The present invention relates to such an agent in which the liquid concentrate contains one component as a fatty acid and other surfactants and the other component contains the alkali required for soap formation.

Aus der GB-PS 338 121 ist ein Waschverfahren unter Verwendung eines Zwei-Komponenten-Waschmittels bekannt. Die 1. Komponente besteht aus seifenbildenden Fettsäuren, wie Palmitinsäure, Stearinsäure oder ölsäure, die im Gemisch mit Emulgiermitteln bzw. Lösungsmitteln, wie sulfatiertem Olivenöl, Kohlenwasserstoffen, Terpentin und Chlorkohlenwasserstoffen, vorliegen können. Die 2. Komponente enthält die zur Seifenbildung benötigten Alkalien, wie Alkalihydroxide, -carbonate, -bicarbonate, und -silikate, und wird mit der 1. Komponente erst in der Waschflotte vereinigt. Außerdem können noch Bleichkomponenten zugesetzt werden. Dieses Verfahren weist eine Reihe von Nachteilen auf, die insbesondere in gewerblichen Wäschereien mit hohem Automationsgrad eine Rolle spielen. So lassen sich die genannten Fettsäuren nur schlecht automatisch fördern und dosieren, während die Mitverwendung von Lösungsmitteln aus der Reihe der Kohlenwasserstoffe bzw. der Chlorkohlenwasserstoffe erhebliche Probleme, wie erhöhte Brand- und Explosionsgefahr bzw. toxikologische Bedenken, aufwirft. Außerdem verläuft die Umsetzung zwischen den in der Waschflüssigkeit nicht hinreichend fein dispergierten Fettsäuren und dem Alkali verhältnismäßig langsam, insbeisondere bei Waschtemperaturen unterhalb 65 C. Die Reaktion wird überdies durch die anwesende Wäsche gehemmt bzw. teilweise unterbunden, so daß es zur Bildung von Fettsäureablagerungen auf dem Waschgut kommen kann.From GB-PS 338 121 a washing method using a two-component detergent is known. The first component consists of soap-forming fatty acids, such as palmitic acid, stearic acid or oleic acid, which can be present in a mixture with emulsifiers or solvents, such as sulfated olive oil, hydrocarbons, turpentine and chlorinated hydrocarbons. The second component contains the alkalis required for soap formation, such as alkali metal hydroxides, carbonates, bicarbonates and silicates, and is only combined with the first component in the wash liquor. Bleaching components can also be added. This process has a number of disadvantages, particularly in commercial laundries high degree of automation play a role. It is difficult to automatically feed and dose the fatty acids mentioned, while the use of solvents from the range of hydrocarbons or chlorinated hydrocarbons poses considerable problems, such as increased risk of fire and explosion or toxicological concerns. In addition, the reaction between the fatty acids which are not sufficiently finely dispersed in the washing liquid and the alkali is relatively slow, in particular at washing temperatures below 65 C. The reaction is moreover inhibited or partially prevented by the laundry present, so that it forms fatty acid deposits on the Laundry can come.

Ein weiteres, aus der FR-PS 1 460 904 bekanntes Verfahren geht von wäßrigen, zur Seifenbildung geeigneten Fettsäureemulsionen aus, die in der Waschlauge mit den Waschalkalien vereinigt werden. Die Fettsäure, bei der es sich vorzugsweise um technische ölsäure bzw. um ein niedrigschmelzendes Fettsäuregemisch (Titer 45 °C) handelt, wird mit einem nichtionischem Emulgator, wie Polyoxyethylensorbitan-monolaurat bzw. -monostearat, gegebenenfalls unter Zusatz von destilliertem Tallöl, in Wasser emulgiert. Alkalisch reagierende Stoffe dürfen nicht zugesetzt werden, da diese zu einem Brechen der Emulsionen führen. Es hat sich nun gezeigt, daß das Reinigungsvermögen der Mittel vergleichsweise gering ist, da die verwendeten Emulgatoren nicht nennenswert zur Waschkraft beitragen. Weiterhin ist die Beständigkeit, insbesondere die Kältestabilität der Emulsionen mangelhaft, da es unterhalb des Gefrierpunktes zu Entmischungen kommt, die sich nach dem Erwärmen nicht mehr ohne weiteres rückgängig machen lassen.Another method known from FR-PS 1 460 904 is based on aqueous fatty acid emulsions suitable for soap formation, which are combined with the washing alkalis in the wash liquor. The fatty acid, which is preferably technical oleic acid or a low-melting fatty acid mixture (titer 45 ° C.), is emulsified in water with a nonionic emulsifier, such as polyoxyethylene sorbitan monolaurate or monostearate, optionally with the addition of distilled tall oil . Substances with an alkaline reaction must not be added, as these will break the emulsions. It has now been shown that the cleaning power of the compositions is comparatively low, since the emulsifiers used do not make any notable contribution to the detergency. Furthermore, the stability, in particular the low-temperature stability, of the emulsions is poor, since segregation occurs below the freezing point, which cannot be easily reversed after heating.

Trotz dieser Probleme besaht weiterhin Interesse an flüssigen Mitteln der vorgenannten Arte insbesondere in Form hochkonzentrierter Zubereitungen. Hochkonzentrierte Mittel gestatten es, die Kosten für Verpackung, Transport und Lagerung niedrig zu halten. Als Flüssigmittel besitzen sie außerdem den Vorteil der leichten Förder- und Dosier- barkeit. Dies bietet nicht nur für gewerbliche Wäschereien die mit entsprechenden Ansatz- und Vorratstanks ausgestattet sind, entscheidende Vorteile, sondern auch für die z. Zt. in Entwicklung begriffenen, mit Vorrats- und 'Dosiervorrichtungen ausgerüsteten Haushaltswaschmaschinen. Bei diesen neuartigen Geräten ist die Waschmitteldosierung auf das jeweilige Waschprogramm speziell abgestimmt, wodurch unerwünschte bzw. abwasserbelastende Fehldosierungen vermieden werden.Despite these problems, there is still interest in liquid agents of the aforementioned type e, in particular in the form of highly concentrated preparations. Highly concentrated agents make it possible to keep packaging, transport and storage costs low. Also as liquid funds, they have the advantage of easy handling and D osier- bility. This not only offers decisive advantages for commercial laundries that are equipped with appropriate batch and storage tanks, but also for the z. Household washing machines currently in development, equipped with storage and dosing devices. With these new devices, the detergent dosage is specifically matched to the respective washing program, which prevents undesirable or wastewater-incorrect dosing.
