Description

Insektenabwehrmittel Die Verwendung zahlreicher organischer Substanzen, -insbesondere stark riechender Stoffe, z. B. von Cumarin, zum Abwehren von Insekten ist bekannt. Die Wirkung dieser Stoffe ist recht unbefriedigend und insbesondere rasch vorübergehend. Auch ein Zusatz von Kochsalz oder troc'k'enen, festen Verteilungsmitteln,, wie Talkum, oder säurebindenden Materialien, wie Calciumcarbonat, kann die Abwehrwirkung praktisch nicht verlängern. Ferner ist es bekannt, daß Magnesiumchlorid eine gewisse insektenabwehrende Wirkung besitzt.Insect repellants The use of numerous organic substances - especially strong smelling substances such. B. of coumarin, to repel insects is known. The effect of these substances is quite unsatisfactory and in particular quickly temporarily. An addition of table salt or dry, solid distribution agents, such as talc, or acid-binding materials, such as calcium carbonate, can have the repellent effect practically do not extend. It is also known that magnesium chloride has a certain Has an insect repellent effect.

Es wurde nun gefunden, daß die kombinierte Anwendung von Cumarin oder dessen Substitutionsprodukten, denen an sich schon eine gewisse Abwehrwirkung gegen Insekten zukommt, mit löslichen Salzen des Calciums oder Strontiums eine Steigerung der Insektenabwehrwirkung herbeiführt. Erst durch diese Kombination wird eine praktisch befriedigende Wirkung tatsächlich erzielt.It has now been found that the combined use of coumarin or its substitution products, which in themselves already have a certain protective effect against Insects get an increase with soluble salts of calcium or strontium the insect repellent effect. Only through this combination does one become practical satisfactory effect actually achieved.

So hat sich z. B. gezeigt, daß, unter gleichen chen Bedingungen gegen die Mückenart aedes aegypti geprüft, eine Mischung von i o Gewichtsteilen Cumarin und i oo Gewichtsteilen 96o/oigem Alkohol nach a Stunden schon anfängt, ihre Abwehrwirkung zu verlieren, selbst wenn man ihr i o Teile Talkum oder Caliumcarbonat zusetzt oder die Lösung mit Kochsalz sättigt, während nach Zusatz von i o Gewichtsteilen Calciumchlorid nach 9 Stunden noch die volle Abwehrwirkung festgestellt wurde.So has z. B. shown that, under the same chen conditions against the mosquito species aedes aegypti tested, a mixture of 10 parts by weight of coumarin and 100 parts by weight of 96% alcohol after an hour already begins to have its protective effect to lose, even if you add 10 parts of talc or potassium carbonate or the solution is saturated with table salt, while after the addition of 10 parts by weight of calcium chloride after 9 hours the full defense effect was found.

Neben Cumarin kommen als Substitutionsprodukte des Cumarins z. B. 3-Methylcumarin, 3-Athylcumarin, q.-Methylcumarin, ¢-Athyl-oder q.-Isopropylcumarin, q.-Brom-, q.-Chlor-oder 4-Fluorcumarin sowie 3-Clor-, 3-Phenyl-oder q.-Phenylcumarin in Frage. Auch Dierivate der p-Oxycumarsäurey. wie Umbelliferon oder 3-Methylumbelliferon, können verwendet werden. Solche Substitutionsprodukte des Cumarins sind als Insektenabwehrmittel bereits bekannt.In addition to coumarin, as substitution products of coumarin z. B. 3-methylcoumarin, 3-ethylcoumarin, q.-methylcoumarin, ¢ -ethyl- or q.-isopropylcoumarin, q-bromo, q-chloro or 4-fluorocoumarin and 3-chloro, 3-phenyl or q-phenylcoumarin in question. Also derivatives of p-oxycumaric acid. like umbelliferone or 3-methylumbelliferone, can be used. Such substitution products of coumarin are used as insect repellants already known.

Als lösliche Salze der obengenannten Metalle erwiesen sich als geeignet z. B. Strontiumbromid, Calciumchlorid oder Calciumrhodanat. Die Menge und Art der einzelnen Bestandteile können in weiten Grenzen variiert werden. Sie können entweder gleichzeitig oder in beliebiger Reihenfolge nacheinander Anwendung finden. Zweckmäßig erfolgt die Anwendung in geeigneter Zubereitung, z. B. unter Zusatz von Streckmitteln,' wie Löse- oder Verdünnemittel, Emulgier-, Dispergier- oder Verdickemittel, so daß die Mittel in Form von Lösungen, Emulsionen, Pasten oder Pudern gebraucht werden können. Als solche Mittel kommen z. B: in Frage: Äthylalkohol, gegebenenfalls etwas wasserhaltig, Isopropanol, Octodecylalkohol; Glycerin, Kieselgur, Talkum, Gips, Wachs und Stärke. Man kann ferner Riechstoffe und Kosmetika zusetzen.Soluble salts of the abovementioned metals have proven to be suitable z. B. strontium bromide, calcium chloride or calcium rhodanate. The amount and type of individual components can be varied within wide limits. You can either can be used simultaneously or in any order one after the other. Appropriate the application takes place in a suitable preparation, z. B. with the addition of extenders, ' such as solvents or thinners, emulsifiers, Dispersants or thickeners, so that the funds are used in the form of solutions, emulsions, pastes or powders can be. As such means come z. B: in question: ethyl alcohol, if applicable some water containing, isopropanol, octodecyl alcohol; Glycerine, kieselguhr, talc, Plaster of paris, wax and starch. You can also add fragrances and cosmetics.

Die folgenden Zubereitungen haben sich z. B. als geeignete Insektenabwehrmittel erwiesen: Beispieli i o Gewichtsteile Cumarin, 10 - Calciumchlorid und 80 - 96%iger Alkohol. Beispiel 2 5 Gewichtsteile Nelkenöl, 3 - Cumarin, 8 - Strontiumbromid, 6 - Calciumchlorid und 78 - 85%iger Alkohol.

Beispiel 9 15 Gewichtsteile Methyl-4-cumarin, I i - Calciumchlorid, 135 - 96%iger Alkohol. The following preparations have z. B. proven to be suitable insect repellants: Example i 10 parts by weight of coumarin, 10 - calcium chloride and 80-96% alcohol. Example 2 5 parts by weight of clove oil, 3 - coumarin, 8 - strontium bromide, 6 - calcium chloride and 78-85% alcohol.
