Description
Gebrauchsfertiges Mittel zur Bekämpfung von schädlichen Bakterien auf textilen Materialien
Gegenstand der Erfindung ist ein gebrauchsfertiges Mittel zur Bekämpfung schädlicher Bakterien auf textilen Materialien. Das Mittel enthält als Wirkstoff den N-3 ,4-Dichlorphenyl-N'-2-äthylhexyl-( 1) - harnstoff der Formel
EMI1.1
Diese Verbindung kann durch Umsetzung von 2 ithyl-hexyl-(l)-amin mit 3,4 - Dichlorphenylisocyanat erhalten werden.
Aus der belgischen Patentschrift Nr. 673 848 und der schweizerischen Auslegeschrift Nr. 16 314/64 sind N-3 ,4-Dichlorbenzyl-phenyl-harnstoffe bekannt. In der südafrikanischen Patentschrift Nr. 66/2358 wird ein N-3 ,4-Dichlorphenyl-N'-n-octyl-( 1) - harnstoff und im Journal of the American Chemical Society , Bd. 79 (1957), Seite 1238, ein N-3 ,4-Dichlorphenyl-N'-tertiär- octyl-harnstoff beschrieben. Alle diese bekannten Harnstoffderivate haben im Vergleich zum vorliegenden N-3 ,4-Dichlorphenyl-N'-2-äthylhexyl-( 1) - harnstoff eine geringere Löslichkeit sowohl in polaren als auch unpolaren Lösungsmitteln, wodurch die Anwendung dieser bekannten Harnstoffe auf einen viel engeren Bereich eingeschränkt ist.
Die gebrauchsfertigen Mittel zur Bekämpfung schädlicher Bakterien, welche den N-3,4-Dichlorphenyl N'-2-äthylhexyl-(l)-harnstoff enthalten, können im übrigen in üblicher, an sich bekannter Weise hergestellt und angewendet werden. Besonders wertvoll an den neuen Mitteln ist das breite antibakterielle Wirkungsspektrum, das sich sowohl auf grampositive als auch gramnegative Bakterien erstreckt. Hierbei ist in anwendungstechnischer Hinsicht die Geruchlosigkeit und Farblosigkeit des N-3 ,4-Dichlorphenyl-N'-2-äthylhexyl (l)-harnstoffes von besonderem Wert. Die Verwendung zum Schutze von textilen Substraten ist auf sehr breiter Basis möglich gegen den Befall durch zerstörende und pathogene Bakterien.
Der N-3 ,Dichlorphenyl-N' 2-äthylhexyl-(1)-harnstoff eignet sich demnach sowohl als Konservierungsmittel wie auch als Desinfektionsmittel für Textilien und technische Produkte der Textilindustrie.
Unter den technischen Produkten, welche mit Hilfe von N-3 ,4-Dichlorphenyl-N'-2-äthylhexyl-( 1) - harnstoff konserviert werden können, seien die folgenden als Beispiele herausgegriffen:
Textilhilfsmittel bzw. Veredlungsmittel und Farbzubereitungen auf der Basis von organischen und anorganischen Farbstoffen bew. Pigmenten, auch solche, welche als Beimischungen Casein oder andere organische Verbindungen enthalten.
Weiterhin kann N - 3,4 - 4-Dichlorphenyl-N'-2-äthyl- hexyl-(l)-harnstoff zur konservierenden und desinfizierenden Ausrüstung von Fasern und Textilien verwendet werden, wobei er auf natürliche und künstliche Fasern aufgebracht werden kann und dort eine dauerhatte Wirkung gegen schädliche (auch pathogene) Bakterien entfaltet. Der Zusatz kann dabei vor, gleichzeitig mit oder nach einer Behandlung dieser Textilien mit anderen Stoffen. z. B. Farb- oder Druckpasten, Appreturen usw., erfolgen.
Derart behandelte Textilien weisen auch einen Schutz gegen das Auftreten von Schweissgeruch, wie er durch Bakterien bedingt ist, auf.
Ferner gelangt man durch Kombination von N-3,4- Dichlorphenyl-N'-2-äthylhexyl-(1)-harnstoff mit waschbzw. oberflächenaktiven Stoffen zu Waschmitteln für textile Materialien mit ausgezeichneter antibakterieller Wirkung. Dieser Harnstoff kann z. B. in Seifen eingearbeitet, mit seifenfreien, wasch- bzw. oberflächenaktiven Stoffen oder mit Gemischen aus Seifen und seifenfreien waschaktiven Stoffen kombiniert werden, wobei in diesen Kombinationen seine antibakterielle Wirksamkeit in vollem Umfang erhalten bleibt.
Der N-3 ,4-Dichlorphenyl-N1-äthylhexyl-( 1)-harnstoff kann auf zu schützende Textilmaterialien in verschiedenster Weise aufgebracht werden, zum Beispiel durch Imprägnieren oder Besprühen mit Lösungen oder Suspensionen, die die genannte Verbindung als Wirkstoff enthalten. Der Wirkstoffgehalt kann hierbei je nach Anwendungszweck zwischen 1 und 30 g Wirksubstan pro Liter Behandlungsflüssigkeit liegen. Meistens werden textile Materialien sowohl synthetischer oder natürlicher Herkunft durch einen Gehalt von 0,1 bis 3 % Wirkstoff ausreichend gegen Bakterienbefail geschützt. Der Wirkstoff kann zusammen mit anderen textilen Hilfsmitteln wie Appreturmitteln, Knitterfestausrüstungen usw. eingesetzt werden.
Die Anwendungsformen können den üblichen Formulierungen von Schädlingsbekämpfungsmitteln entsprechen, beispielsweise können Mittel, die N-3 ,4Di- cholrphenyl-N'-2-äthylhexyl-( 1) -harnstoff enthalten, gegebenenfalls auch noch Zusätze wie Trägerstoffe, Lösungsmittel, Verdünnongs-, Dispergier-, Netz- oder Haftmittel usw. sowie andere Schädlingsbekämpfungsmittel, z. B. fungizide oder fungistatische Mittel, enthalten.
Die in der nachfolgenden Herstellungsvorschrift und im Beispiel angegebenen Teile sind Gewichtsteile, die Prozente Gewichtsprozente, sofern nichts anderes angegeben.

In gleicher Weise werden auch Muster von 100 g Wollcheviot behandelt
Die bei 30 bis 400 C getrockneten Gewebe enthalten 0, 1 % Wirkstoff, bezogen auf ihr Eigengewicht.
Zur Prüfung der Wirkung gegen Bakterien werden Rondelle von 10 mm Durchmesser der imprägnierten Gewebe (ungewässert und nach EMPA-Wässerung) auf Glucose-Agar-Platten gelegt, die mit Staphylococcus aureus vorbeimpft sind. Die Platten werden hierauf 24 Stunden bei 370 C bebrütet.
Ready-to-use agent for combating harmful bacteria on textile materials
The invention relates to a ready-to-use agent for combating harmful bacteria on textile materials. The agent contains N-3, 4-dichlorophenyl-N'-2-ethylhexyl- (1) - urea of the formula as active ingredient
EMI1.1
This compound can be obtained by reacting 2 ithyl-hexyl- (l) -amine with 3,4-dichlorophenyl isocyanate.
N-3, 4-dichlorobenzyl-phenyl-ureas are known from Belgian patent specification No. 673 848 and Swiss patent application No. 16 314/64. In the South African patent specification No. 66/2358 an N-3, 4-dichlorophenyl-N'-n-octyl- (1) - urea and in the Journal of the American Chemical Society, Vol. 79 (1957), page 1238, an N-3, 4-dichlorophenyl-N'-tertiary octyl urea described. All these known urea derivatives have, compared to the present N-3, 4-dichlorophenyl-N'-2-ethylhexyl- (1) - urea, a lower solubility in both polar and non-polar solvents, whereby the use of these known ureas is much narrower Area is restricted.
The ready-to-use agents for combating harmful bacteria, which contain N-3,4-dichlorophenyl N'-2-ethylhexyl- (1) -urea, can moreover be prepared and used in a conventional manner. What is particularly valuable about the new products is the broad spectrum of antibacterial activity, which extends to both gram-positive and gram-negative bacteria. From an application point of view, the odorlessness and colorlessness of the N-3,4-dichlorophenyl-N'-2-ethylhexyl (l) urea are of particular value. The use for protecting textile substrates is possible on a very broad basis against attack by destructive and pathogenic bacteria.
The N-3, dichlorophenyl-N '2-ethylhexyl- (1) -urea is therefore suitable both as a preservative and as a disinfectant for textiles and technical products in the textile industry.
Among the technical products that can be preserved with the help of N-3, 4-dichlorophenyl-N'-2-ethylhexyl- (1) - urea, the following are examples:
Textile auxiliaries or finishing agents and color preparations based on organic and inorganic dyes, particularly pigments, including those which contain casein or other organic compounds as admixtures.
Furthermore, N - 3,4 - 4-dichlorophenyl-N'-2-ethyl-hexyl- (l) -urea can be used for preserving and disinfecting fibers and textiles, whereby it can be applied to natural and artificial fibers and there had a lasting effect against harmful (also pathogenic) bacteria. The addition can be made before, at the same time with or after treating these textiles with other substances. z. B. color or printing pastes, finishes, etc., take place.
Textiles treated in this way also have protection against the occurrence of sweat odor, as is caused by bacteria.
Furthermore, by combining N-3,4-dichlorophenyl-N'-2-ethylhexyl- (1) -urea with washing or. Surface-active substances for detergents for textile materials with excellent antibacterial properties. This urea can e.g. B. incorporated into soaps, combined with soap-free, detergent or surface-active substances or with mixtures of soaps and soap-free detergent substances, with its antibacterial effectiveness being fully retained in these combinations.
The N-3, 4-dichlorophenyl-N1-ethylhexyl- (1) -urea can be applied to textile materials to be protected in a wide variety of ways, for example by impregnation or spraying with solutions or suspensions which contain the named compound as an active ingredient. The active ingredient content can be between 1 and 30 g of active ingredient per liter of treatment liquid, depending on the application. Textile materials of both synthetic and natural origin are mostly protected against bacterial contamination by a content of 0.1 to 3% active ingredient. The active ingredient can be used together with other textile aids such as finishing agents, anti-crease treatments, etc.
The use forms can correspond to the customary formulations of pesticides, for example agents which contain N-3,4-dicholrphenyl-N'-2-ethylhexyl- (1) -urea, optionally also additives such as carriers, solvents, diluents, dispersants -, wetting or adhesive agents etc. as well as other pesticides, e.g. B. fungicidal or fungistatic agents contain.
The parts given in the following manufacturing instructions and in the example are parts by weight and the percentages are percentages by weight, unless otherwise stated.
