Description

Die vorliegende Erfindung betrifft eine Trockenreinigungszusammensetzung, enthaltend 0,1 bis 10 Gewichtsprozent eines Trockenreinigungsdetergens und 0,001 bis 1,0 Gewichtsprozent Wasser. Diese Trockenreinigungszusammensetzung ist dadurch gekennzeichnet, daß sie Phosphorsäure in einer Menge von 0,001 bis 1,0 Gewichtsprozent enthält.The present invention relates to a dry cleaning composition, containing 0.1 to 10 percent by weight of a dry cleaning detergent and 0.001 to 1.0 percent by weight of water. These Dry cleaning composition is characterized by that it contains phosphoric acid in an amount of 0.001 to 1.0 percent by weight.

In der deutschen Patentschrift 976 341 sowie in der deutschen Auslegeschrift 1023 546 werden Trokkenreinigungsmittel beschrieben, die neben üblichen Bestandteilen, wie organischen Lösungsmitteln, Waschaktivsubstanzen als Reinigungsverstärker und Wasser, Anteile von Phosphaten enthalten.In the German patent specification 976 341 and in the German Auslegeschrift 1023 546 dry cleaning agents described, in addition to the usual ingredients such as organic solvents, washing active substances as cleaning enhancers and Water, containing proportions of phosphates.

Aus der deutschen Auslegeschrift 1004759 sind Phosphorsäure enthaltende chemische Reinigungsmittel bekannt.From the German Auslegeschrift 1004759 are chemical cleaning agents containing phosphoric acid known.

Durch keine der vorstehend genannten Literaturstellen wird jedoch die erfindungsgemäß in überraschender Weise gewonnene Erkenntnis nahegelegt, daß kleine Mengen an Phosphorsäure (0,001 bis 1,0 Gewichtsprozent) Gerüche, welche sich bereits nach einer kurzen Lagerungszeit aus den Trockenreinigungsformulierungen der erfindungsgemäßen Art entwickeln, zu unterdrücken vermögen. Diese geruchsunterdrückende Wirkung der Phosphorsäure 7,5 wird bei Phosphorsäureestern nicht festgestellt.However, none of the above-mentioned references suggests the surprisingly obtained knowledge according to the invention that small amounts of phosphoric acid (0.001 to 1.0 percent by weight) are able to suppress odors which develop from the dry cleaning formulations of the type according to the invention after a short storage time . This odor-suppressing effect of phosphoric acid 7.5 is not found in phosphoric acid esters.

Versuche in der Praxis haben gezeigt, daß bei Verwendung von handelsüblichen Trockenreinigungslösungen, die übliche Detergentien enthalten und einen Feuchtigkeitsgehalt unter etwa 1 % aufweisen, durch den Zusatz von 0,001% Phosphorsäure das Lösungsmittel während einer Zeitspanne von mehr als 1 Jahr frei von Gerüchen gehalten werden kann.Tests in practice have shown that when using commercially available dry cleaning solutions, which contain normal detergents and have a moisture content below about 1%, the addition of 0.001% phosphoric acid reduces the solvent for a period of time longer can be kept odor free for more than 1 year.

Durch den erfindungsgemäßen Zusatz von Phosphorsäure in den angegebenen Mengen erübrigt sich daher die bisher erforderliche Zugabe von Klärungsoder Sauberhaltungsmitteln, wie beispielsweise alkalischen Tonen, die von Zeit zu Zeit aus der Trockenreinigungszusammensetzung, beispielsweise durch Filtration, entfernt werden müssen.The addition of phosphoric acid according to the invention in the amounts indicated is therefore unnecessary the previously required addition of clarifying agents or cleaning agents, such as alkaline ones Clays from time to time from the dry cleaning composition, for example by filtration, must be removed.

Der erfindungsgemäßen Trockenreinigungszusammensetzung können selbstverständlich neben Wasser auch andere übliche Zusätze, wie beispielsweise den Griff verbessernde Mittel, Schlichtemittel oder Mottenschutzmittel zugesetzt werden, ohne daß dabei die Wirksamkeit des Systems beeinträchtigt wird.The dry cleaning composition according to the invention can of course in addition to water also other customary additives, such as, for example, hand-improving agents, sizing agents or moth repellants can be added without affecting the effectiveness of the system.

Der wirksamste Phosphorsäurebereich liegt zwischen 0,005 und 1 Gewichtsprozent, bezogen auf die Trockenreinigungszusammensetzung.The most effective phosphoric acid range is between 0.005 and 1 percent by weight based on the Dry cleaning composition.

Eine typische erfindungsgemäße Trockenreinigungszusammensetzung enthält folgende Bestandteile: A typical dry cleaning composition according to the invention contains the following ingredients:

2,0 Gewichtsprozent Phosphorsäureester des2.0 weight percent phosphoric acid ester des

Tridecylalkoholäthoxylats,Tridecyl alcohol ethoxylate,
