Description

Verfahren zur Herstellung eines Schutzmittels gegen Mücken und Bremsen Die zu dem Zwecke der Mücken- und Bremsenabwehr seither benutzten sogenarnnten Mückensteine erweisen sich trotz aller Vorkehrungen mechanischer Beanspruchung gegenüber nur wenig widerstandsfähig, so daß ein verhältnismäßig großer Teil der Steine durch Bruch unverkäuflich wird. Die Herstellung selbst bietet eine Reihe von Schwierigkeiten, wie z. B. die Bindung der flüssigen, wirksamen Bestandteile an den festen, porösen oder staubförmigen Träger oder das Formen und Trocknen der Steine, das stets mit großen Verlusten an wirksamen Stoffen verbunden ist.Process for the production of a protective agent against mosquitoes and horseflies The so-called mosquito stones that have been used since then for the purpose of repelling mosquitoes and horseflies prove to be in spite of all precautions against mechanical stress only little resistant, so that a relatively large part of the stones through Breakage becomes unsaleable. The manufacture itself presents a number of difficulties, such as B. the binding of the liquid, active ingredients to the solid, porous or dusty carriers or the shaping and drying of the stones, which is always with large losses of active substances are associated.

Diese Nachteile können vermieden werden, wenn man in, bekannter Weise als Träger paraffin-, stearin- oder wachsartige Stoffe wählt. Diese lassen sich durchweg bei verhältnismäßig niedriger Temperatur verflüssigen, worauf man die wirksamen Bestandteile in Form ätherischer Öle hinzufügt, die Mischung in geeignete Formen gießt und rasch abkühlt. Auf diese Weise wird der Verlust an ätherischen Ölen auf ein Mindestmaß beschränkt und eine gleichmäßige, fest zusammenbackende Mischung erzielt. Leider sind so hergestellte Mückensteine in wärmeren Zonen, den Hauptverwendungsgebieten der Insektenabwehrmitt:el, wegen der Gefahr des Zerfließens nicht verwendbar. Es wurde nun gefunden, daß man überraschend einfach unter Vermeidung des umständlichen Tauchverfahrens und der damit verbundenen verlustreichen, Nachtrocknung mit wässeriger Stärkelösung als Bindemittel widerstandsfähige, tropenfeste Mückenschutzmittel erhält durch Mischen von erdigen Massen mit geschmolzenen, paraffinartigen Stoffen und ätherischen Ölen.These disadvantages can be avoided if one works in a known manner as a carrier selects paraffin, stearic or waxy substances. These can consistently liquefy at a relatively low temperature, whereupon the effective Adding ingredients in the form of essential oils to the mixture in suitable forms pours and cools quickly. This way, the loss of essential oils will increase a minimum and an even, firmly caked mixture achieved. Unfortunately mosquito stones produced in this way are the main areas of use in warmer zones the insect repellant, cannot be used because of the risk of dissolution. It it has now been found that it is surprisingly easy to avoid the cumbersome Immersion process and the associated lossy, post-drying with aqueous The starch solution as a binding agent contains resistant, tropicalized mosquito repellants by mixing earthy masses with molten, paraffin-like substances and essential oils.

Dieser Mischung kann man durch einfaches Erstarrenlassen jede gewünschte Form geben, so daß damit das Blockschneiden oder -pressen sowie jede Nachtrocknung ientfällt..This mixture can be made any desired by simply allowing it to solidify Give shape so that block cutting or pressing as well as every subsequent drying process i not applicable ..

Als Füllstoffe kommen in Betracht: Magnesia, Kalk, Bolus, Talkum" Kieselgur. Abschreckende Mittel sind: ätherische Öle, wie Eukalyptusöl, Nelkenöl, Lorbeeröl, Petersilienöl, Pfeffermünzöl, Kampfer, Stinkasant und andere.
