Description
Die vorliegende Erfindung betrifft ein neuartige Alkylphenole enthaltendes handelsfähiges Mittel und die Verwendung des neuen Mittels als Futterzusatz für Nutztiere.
Die im erfindungsgemässen Mittel als aktive Komponente enthaltene neuen Alkylphenole entsprechen der Formel I
EMI1.1
in der X1 Halogen, Alkyl oder Halogenalkyl.
X2 Halogen und m eine ganze Zahl von 1 bis 11 bedeutet.
Als Verbindungen der Formel I werden diejenigen bevorzugt, bei denen Xt Chlor, Brom, Alkyl mit 1 bis 4 C-Atomen, vorzugsweise Methyl, oder Trifluormethyl,
X2 Chlor oder Brom und m eine ganze Zahl von 1 bis 6 bedeutet, wobei sich X2 bevorzugt in meta- oder para-Stellung zur OH-Gruppe befindet. Zu dieser Gruppe gehören insbesondere die Verbindungen der Formel II
EMI1.2
in der X1 und X2 Chlor oder Brom bedeuten und m eine ganze Zahl von 1 bis 6 ist.
Eine Anzahl von Alkylphenolen und entsprechende Mittel zur Bekämpfung von Mikroorganismen, vor allem von gram-positiven Bakterien, sind bereits bekannt (vgl. K. H.
Wallhäuser und H. Schmidt, < Sterilisation, Desinfektion, Konservierung, Chemoterapie , Georg Thieme Verlag, 1967).
Es wurde nun überraschenderweise gefunden, dass die in dem erfindungsgemäss vorgeschlagenen Mittel enthaltenen neuartigen Alkylphenole der Formel I aufgrund ihrer speziellen Substitution auch gegenüber gram-negativen Bakterien und gegenüber Schimmelpilzen sehr wirksam sind. Diese Verbindungen zeigen vorteilhafterweise ein ausgesprochen breites Wirkungsspektrum, aber nur schwache Toxizität. Sie können auch mit Erfolg in Beifuttermitteln zur Förderung des Wachstums von Nutztieren eingesetzt werden. Ein besonderer Vorteil der Verbindungen der Formel list darin zu erblicken, dass sie schon bei relativ geringen Konzentrationen über eine einfache Hemmwirkung hinaus zu einer völligen Abtötung der zu bekämpfenden Mikroorganismen führen.
In anwendungstechnischer Hinsicht ist die Farblosigkeit der in den erfindungsgemässen Mitteln enthaltenen Verbindungen der Formel I sowie ihre geringe Geruchsentwicklung von besonderem Wert.
Die Alkylphenole der Formel I können hergestellt werden durch Reduktion von Ketonen der Formel III
EMI1.3
in der X1, X2 und m die oben angegebene Bedeutung haben.
Dementsprechend lassen sich z. B. die Verbindungen der Formel II aus dem Keton der Formel IV
EMI1.4
herstellen, in der X1, X2 und m die oben angegebene Bedeutung haben.
Die Reduktion der Ketone kann nach verschiedenen, an sich bekannten Methoden erfolgen. So kann z. B. die Reduktionsmethode nach Wolff-Kishner (vgl. D. Todd, Organic Reactions 4, 378; 1948) erfolgreich angewendet werden.
Diese besteht darin, das man das Keton zuerst in das Hydrazon überführt und dieses mit Natriumäthylat bei erhöhter Temperatur und unter Druck zum entsprechenden Kohlenwasserstoff zersetzt. Nach einem modifizierten Verfahren nach Huang-Minlon (vgl. Huang-Minlon, Journal of the American Chemical Society 68, 2487; 1946) erfolgt die Zer- setzung des Hydrazons in einem inerten Lösungsmittel bei erhöhter Temperatur, jedoch bei Normaldruck mit Hilfe einer anorganischen Base.
Man geht dabei mit Vorteil so vor, dass man zuerst das Keton in einem inerten, hochsiedenden, mit Wasser mischbaren Lösungsmittel zusammen mit einem Überschuss Hydrazinhydrat und einem Alkalihydroxid auf 100 bis 1500 C erhitzt und dann das gebildete Hydrazon nach Abdestillieren des Wassers und überschüssigen Hydrazinhydrats durch Erhitzen auf 180-220 C zersetzt.
Besonders gute Ausljeuten ergeben sich, wenn als Lö sungsmittel Glykole, wie Äthylenglykol, Diäthylenglykol oder Triäthylenglykol verwendet werden. Als Alkalihydroxide werden mit Vorteil Natrium- oder Kaliumhydroxid eingesetzt, in der Regel pro Mol zu reduzierendem Keton 3 bis 7 Mol.
Die Bildung des Hydrazons erfolgt am besten, wenn bei einer Temperatur von 120-140 C mit einem Überschuss von 3 bis 7 Mol Hydrazinhydrat pro Mol Keton gearbeitet wird.
Die Zersetzung der gebildeten Hydrazone erfolgt am vorteil haftesten bei einer Temperatur zwischen 190 bis 210 C. Die zur Bildung des Hydrazons benötigten Reaktionszeiten liegen zwischen 30 Minuten und 3 Stunden, diejenigen für die Zer setzung des Hydrazons zwischen 1 und 5 Stunden.
Mit der Clemmensen-Reduktion (vgl. E. Clemmensen,
Berichte der deutschen Chemischen Gesellschaft 46, 1837;
1913 und daselbst 47, 51, 681; 1914 sowie E. L. Martin,
Journal of the American Chemical Society 58, 1438; 1936) besitzt man eine weitere gute Methode zur Herstellung der
Alkylphenole aus den entsprechenden Ketonen. Die Reduk tion erfolgt hier durch Erwärmen der Ketone mit amalgamier tem Zink und Salzsäure gegebenenfalls in Gegenwart eines organischen Lösungsmittels. Infolge der schlechten Wasser löslichkeit der Ketone der Formel III ist es vorteilhaft, die
Reduktion in Anwesenheit von wassermischbaren organi schen Lösungsmitteln wie z. B. Äthanol, Essigsäure oder
Dioxan durchzuführen. Die Reduktion ergibt besonders gute
Ausbeuten, wenn man 8 bis 15 Grammatome Zinkamalgam pro Mol zu reduzierendes Keton einsetzt.
Die Reaktionstemperatur kann z. B. zwischen 20 C und der Siedetemperatur der verwendeten Lösungsmittel variiert werden; die Reaktionszeiten betragen dementsprechend 48 bis 1 Stunden.
Als weitere Reduktionsmethode kommt die hydrierende
Spaltung der aus den Ketonen der Formel III hergestellten
Dialkylthioketalen oder Äthylenthioketalen mit Raney-Nickel (vgl. L. F. Fieser und W.-Y. Huang, Journal of the American Chemical Society 75, 5356; 1953) in Frage.
Ferner sei noch auf die katalytische Hydrierung der Ketone der Formel III zu den entsprechenden Alkylphenolen hingewiesen.
Die vorstehend als Ausgangsprodukte erwähnten Ketone der Formel III sind bekannt (vgl. A. B. Sen und P. M. Bhargava, Journal of the Indian Chemical Society 26, 287-290; 1949) oder werden nach an sich bekannten Methoden hergestellt, z. B. aus den entsprechenden Alkancarbonsäurephenylestern durch die Fries-Reaktion (vgl. Baltzly et al., Journal of the American Chemical Society 77, 2522; 1955 oder G. A. Olah, Friedel-Crafts and Related Reactions 1964, Seite 499). Die Reaktion kann in der Schmelze oder in Gegenwart eines organischen Lösungsmittels, z. B. Nitrobenzol, durchgeführt werden. Beim Erhitzen der entsprechenden Phenylester zusammen mit Aluminiumchlorid entstehen dann die Ketone der Formel III.
Als weitere Methode zur Herstellung von Alkylphenolen der Formel I sei noch die Chlorierung oder Bromierung von Verbindungen der Formel V
EMI2.1
in der X1 und m die oben angegebene Bedeutung haben, er wähnt.
Die Verbindungen der Formel I zeigen gute Löslichkeit in organischen Lösungsmitteln. Ihre wasserlöslichen Salze, speziell die Alkali- und Erdalkalisalze, sind ebenfalls wirksam und dort von besonderer Bedeutung, wo eine Anwendung in wässrigem Medium und Seifen in Betracht gezogen wird.
Die Verwendung der antimikrobiellen Mittel gemäss der vorlipgenden Erfindung ist auf sehr breiter Basis möglich, insbesondere zum Schutze von organischen Substraten gegen den Befall durch schädigende und pathogene Mikroorganis men. Die erwähnten Antimikrobika eignen sich demnach als
Konservierungs- und Desinfektionsmittel für technische Pro dukte aller Art.
Unter den technischen Produkten, welche mit Hilfe der erfindungsgemässen Mittel konserviert werden können, seien die folgenden als Beispiele genannt:
Leime, Bindemittel, Anstrichmittel, Textilhilfsmittel bzw.
Veredlungsmittel, Farb- bzw. Druckpasten und ähnliche Zubereitungen auf der Basis von organischen und anorganischen Farbstoffen bzw. Pigmenten, auch solche, welche als Beimischungen Casein oder andere organische Verbindungen enthalten. Auch Wand- und Deckenanstriche, z. B. solche, die ein eiweisshaltiges Farbbindemittel enthalten, werden durch einen Zusatz der erfindungsgemässen Verbindungen vor dem Befall durch Schädinge geschützt. Die Verwendung zum Holzschutz ist gleichfalls möglich.
Auch in der Zellstoff- und Papirindustrie können die erfindungsgemässen Mittel als Konservierungsmittel eingesetzt werden, u. a. zur Verhütung der bekannten, durch Mikroorganismen hervorgerufenen Schleimbildung in den zur Papiergewinnung verwendeten Apparaturen.
Die Wirkung der erfindungsgemässen Mittel kann auch in konservierenden und desinfizierenden Ausrüstungen von Kunststoffen ausgenützt werden. Bei Verwendung von Weichmachern ist es vorteilhaft, den antimikrobiellen Zusatz dem Kunststoff im Weichmacher gelöst bzw. dispergiert zuzusetzen. Zweckmässig ist für eine möglichst gleichmässige Verteilung im Kunststoff Sorge zu tragen. Die Kunststoffe mit antimikrobiellen Eigenschaften können ür Gebrauchsgegenstände aller Art, bei denen eine Wirksamkeit gegen verschiedenste Keime, wie z. B. Bakterien und Pilze, erwünscht ist, Verwendung finden, so z. B. für Sitzgelegenheiten, Trittroste in Schwimmbädern, etc. Durch Einverleibung in entsprechechende Wachs- und Bohnermassen, erhält man Fussbodenund Möbelpflegemittel mit desinfizierender Wirkung.
Wegen der besseren Löslichkeit in organischen Lösungsmitteln eignen sich die Wirkstoffe der Formel I auch gut für die Zubereitung von Mitteln, die zur Applikation aus nichtwässrigen Medien brauchbar sind. Dabei können die auszurüstenden bzw. zu schützenden Materialien einfach mit den Lösungen imprägniert werden.
Als organische Lösungsmittel kommen beispielsweise Trichloräthylen, Methylenchlorid, Kohlenwasserstoffe, Propylenglykol, Methoxyäthanol, Äthoxyäthanol, Dimethylformamid in Frage, denen noch Verteilungsmittel (z. B. Emulgatoren, wie sulfiertes Rizinusöl, Fettalkoholsulfate usw.) und/ oder andere Hilfsstoffe zugesetzt werden können.
Der Gehalt an Wirkstoffen der Mittel gemäss vorliegender Erfindung kann je nach Anwendungszweck zwischen 0,1 und 50 g, vorzugsweise zwischen 1 und 30 g Wirksubstanz pro Liter Behandlungsflüssigkeit liegen.
Durch Kombination der erfindungsgemäss zu verwendenden Verbindungen mit grenzflächenaktiven, insbesondere waschaktiven Stoffen gelangt man zu Wasch- und Reinigung mitteln mit ausgezeichneter antibakterieller bzw. antimykotischer Wirkung.
Die Wasch- und Reinigungsmittel können in beliebiger, z. B. flüssiger, breiartiger, fester, flockiger oder körniger Form vorliegen. Die erfindungsgemässen Mittel können sowohl mit anionaktiven Verbindungen, wie Seifen und andere Carboxylate (z. B. Alkalisalze höherer Fettsäuren), Abkömmlingen von Schwefel-Sauerstoffsäuren (z. B. Natrium: salz der Dodecylbenzolsulfonsäure, wasserlösliche Salze von Schwefelsäuremonoestern höhermolekularer Alkohole oder ihrer Polyglykoläther, wie etwa lösliche Salze von Dodecylalkohol-sulfat oder von Dodecylalkoholpolyglykoläthersulfat), Abkömmlingen von Phosphor-Sauerstoffsäuren (z. B. Phosphate), Abkömmlingen mit saurem (elektrophilem) Stickstoff in der hydrophilen Gruppe (z. B. Disulfinsalze), als auch mit kationaktiven Tensiden, wie Amine und ihren Salzen (z. B.
Lauryldiäthylentriamin), Oniumverbindungen, Aminoxide oder nichtionogenen Tensiden Polyhydroxyverbindun- gen, Tenside auf Mono- oder Polysaccharidbasis, höhermolekularen Acetylenglykolen Polyglykoläthern (z. B. Polyglyl äther, höherer Fettalkohole, Polyglykoläther höhermolekular alkylierter Phenole), bzw. Gemischen aus verschiedenartiger Tensiden formuliert werden. Dabei bleibt ihre antimikrobielle Wirksamkeit in vollem Umfang erhalten. Der Wirkstoffgehalt der Wasch- und Reinigungsmittel, bezogen auf das Gewicht dieses Mittels, beträgt im allgemeinen 0,01 bis 5%, meistens 0,1 bis 3%. Wässrige Zubereitungen solcher Waschund Reinigungsmittel eignen sich ebenfalls als antimikrobielle Reinigungsmittel in der Lebensmittel- und Getränkeindustrie, z. B. Brauereien, Molkereien, Käsereien und Schlachthöfen.
Im weiteren lassen sich die erfindungsgemässen Mittel auch als kosmetische Präparate, wie z. B. ätherische Öle, Badesalze, Brillantinen, Salben, Gesichtswasser, Haarfärbemittel, Haaröle, Haarwässer, Hautcremes, Hautöle, Kölnisch Wasser, Parfüme, Puder, Schminken, Depilatorien, Sonnenbrandmittel, Zahnpflegemittel usw., formulieren womit diesen Zubereitungen zusätzlich antimikrobielle Wirkung verliehen wird. Dabei genügt im allgemeinen, bezogen auf das Gesamt- gewicht der Zubereitungen, ein Wirkstoffgehalt von 0,01 bis 5 %, vorzugsweise von 0,1 bis 3 %.
Für Desinfektions- und Konservierungszwecke können die Mittel gemäss der Erfindung auch in Kombination mit bereits bekannten antimikrobiellen Mitteln verwendet werden. Hierzu gehören z.
Halogene und Halogenverbindungen mit aktive Halogen z. B. Natriumhypochlorit, Calciumhypochlorit, Chlorkalk, Natrium-p -toluolsulfochloramid, p-Toluolsulfodichloramid, N-Chlorsuccinimid, 1,3 -Dichlor-5,5-dimethyl-hydantoin, Trichlorisocyanursäure, Kaliumdichlorisocyanurat, Jod, Jodtrichlorid, Komplexverbindungen von Jod und Jodtrichlorid mit oberflächenaktiven Mitteln wie Polyvinylpyrrolidon, Alkylphenoxypolyglykolen, Polyoxypropylenglykolen, Alkylaminoäthansulfonsäuren und -sulfonaten, Alkylarylsulfonaten, quaternären Ammoniumverbindungen.

**WARNUNG** Ende DESC Feld konnte Anfang CLMS uberlappen**.
The present invention relates to a marketable composition containing novel alkylphenols and the use of the new composition as a feed additive for farm animals.
The new alkylphenols contained as active component in the composition according to the invention correspond to formula I.
EMI1.1
in which X1 is halogen, alkyl or haloalkyl.
X2 is halogen and m is an integer from 1 to 11.
Preferred compounds of the formula I are those in which Xt is chlorine, bromine, alkyl having 1 to 4 carbon atoms, preferably methyl, or trifluoromethyl,
X2 is chlorine or bromine and m is an integer from 1 to 6, X2 preferably being in the meta or para position to the OH group. This group includes, in particular, the compounds of the formula II
EMI1.2
in which X1 and X2 are chlorine or bromine and m is an integer from 1 to 6.
A number of alkylphenols and corresponding agents for combating microorganisms, especially gram-positive bacteria, are already known (cf. K. H.
Wallhäuser and H. Schmidt, <Sterilization, Disinfection, Preservation, Chemotherapy, Georg Thieme Verlag, 1967).
It has now surprisingly been found that the novel alkylphenols of the formula I contained in the agent proposed according to the invention are also very effective against gram-negative bacteria and against molds due to their special substitution. These compounds advantageously show an extremely broad spectrum of activity, but only weak toxicity. They can also be successfully used in feed additives to promote the growth of farm animals. A particular advantage of the compounds of the formula I is to be seen in the fact that even at relatively low concentrations they lead, beyond a simple inhibitory effect, to a complete destruction of the microorganisms to be combated.
From an application point of view, the colorlessness of the compounds of the formula I contained in the agents according to the invention and their low odor development are of particular value.
The alkylphenols of the formula I can be prepared by reducing ketones of the formula III
EMI1.3
in which X1, X2 and m have the meaning given above.
Accordingly, z. B. the compounds of formula II from the ketone of formula IV
EMI1.4
produce in which X1, X2 and m have the meaning given above.
The ketones can be reduced by various methods known per se. So z. B. the reduction method according to Wolff-Kishner (cf. D. Todd, Organic Reactions 4, 378; 1948) can be used successfully.
This consists in first converting the ketone into the hydrazone and decomposing this with sodium ethylate at elevated temperature and under pressure to give the corresponding hydrocarbon. According to a modified Huang-Minlon process (cf. Huang-Minlon, Journal of the American Chemical Society 68, 2487; 1946), the hydrazone is decomposed in an inert solvent at elevated temperature, but at normal pressure with the aid of an inorganic base .
It is advantageous to proceed in such a way that the ketone is first heated in an inert, high-boiling, water-miscible solvent together with an excess of hydrazine hydrate and an alkali hydroxide to 100 to 1500 ° C. and then the hydrazone formed is through after the water and excess hydrazine hydrate have been distilled off Heating to 180-220 C decomposes.
Particularly good yields are obtained if glycols such as ethylene glycol, diethylene glycol or triethylene glycol are used as solvents. Sodium or potassium hydroxide is advantageously used as the alkali metal hydroxide, generally 3 to 7 mol per mol of ketone to be reduced.
The formation of the hydrazone takes place best when working at a temperature of 120-140 C with an excess of 3 to 7 mol of hydrazine hydrate per mol of ketone.
The hydrazones formed are most advantageously decomposed at a temperature between 190 and 210 ° C. The reaction times required for the formation of the hydrazone are between 30 minutes and 3 hours, those for the decomposition of the hydrazone between 1 and 5 hours.
With the Clemmensen reduction (see E. Clemmensen,
Reports of the German Chemical Society 46, 1837;
1913 and there 47, 51, 681; 1914 and E. L. Martin,
Journal of the American Chemical Society 58, 1438; 1936) one has another good method for making the
Alkylphenols from the corresponding ketones. The reduction takes place here by heating the ketones with amalgamated zinc and hydrochloric acid, optionally in the presence of an organic solvent. As a result of the poor water solubility of the ketones of the formula III, it is advantageous to use the
Reduction in the presence of water-miscible organic solvents such as z. B. ethanol, acetic acid or
Carry out dioxane. The reduction results in particularly good ones
Yields when 8 to 15 gram atoms of zinc amalgam are used per mole of ketone to be reduced.
The reaction temperature can be e.g. B. can be varied between 20 C and the boiling point of the solvent used; the reaction times are accordingly 48 to 1 hours.
Another reduction method is the hydrogenating one
Cleavage of those produced from the ketones of the formula III
Dialkylthioketals or ethylene thioketals with Raney nickel (see L. F. Fieser and W.-Y. Huang, Journal of the American Chemical Society 75, 5356; 1953) in question.
Reference should also be made to the catalytic hydrogenation of the ketones of the formula III to give the corresponding alkylphenols.
The ketones of the formula III mentioned above as starting materials are known (cf. A. B. Sen and P. M. Bhargava, Journal of the Indian Chemical Society 26, 287-290; 1949) or are prepared by methods known per se, e.g. B. from the corresponding alkanecarboxylic acid phenyl esters by the Fries reaction (cf. Baltzly et al., Journal of the American Chemical Society 77, 2522; 1955 or G. A. Olah, Friedel-Crafts and Related Reactions 1964, page 499). The reaction can be carried out in the melt or in the presence of an organic solvent, e.g. B. nitrobenzene can be carried out. When the corresponding phenyl esters are heated together with aluminum chloride, the ketones of the formula III are then formed.
Another method for preparing alkylphenols of the formula I is the chlorination or bromination of compounds of the formula V
EMI2.1
in which X1 and m have the meaning given above, he mentions.
The compounds of the formula I show good solubility in organic solvents. Their water-soluble salts, especially the alkali and alkaline earth salts, are also effective and of particular importance where an application in aqueous medium and soaps is considered.
The use of the antimicrobial agents according to the present invention is possible on a very broad basis, in particular for protecting organic substrates against attack by harmful and pathogenic microorganisms. The mentioned antimicrobials are therefore suitable as
Preservatives and disinfectants for all kinds of technical products.
Among the technical products which can be preserved with the aid of the agents according to the invention, the following are mentioned as examples:
Glues, binders, paints, textile auxiliaries or
Finishing agents, coloring or printing pastes and similar preparations based on organic and inorganic dyes or pigments, including those which contain casein or other organic compounds as admixtures. Wall and ceiling coatings, e.g. B. those that contain a protein-containing dye binder are protected from attack by pests by adding the compounds according to the invention. It can also be used to protect wood.
The agents according to the invention can also be used as preservatives in the pulp and paper industry, u. a. to prevent the known slime formation caused by microorganisms in the apparatus used for paper production.
The effect of the agents according to the invention can also be used in preserving and disinfecting finishes for plastics. When using plasticizers, it is advantageous to add the antimicrobial additive to the plastic dissolved or dispersed in the plasticizer. It is advisable to ensure that it is distributed as evenly as possible in the plastic. The plastics with antimicrobial properties can be used for everyday objects of all kinds that are effective against a wide variety of germs, such as B. bacteria and fungi, is desired to find use such. B. for seating, step gratings in swimming pools, etc. By incorporation in appropriate wax and polishing compounds, you get floor and furniture care products with a disinfectant effect.
Because of their better solubility in organic solvents, the active ingredients of the formula I are also very suitable for the preparation of agents which can be used for application from non-aqueous media. The materials to be equipped or protected can simply be impregnated with the solutions.
Examples of organic solvents that can be used are trichlorethylene, methylene chloride, hydrocarbons, propylene glycol, methoxyethanol, ethoxyethanol, dimethylformamide, to which distributing agents (e.g. emulsifiers, such as sulphurized castor oil, fatty alcohol sulphates etc.) and / or other auxiliaries can be added.
The content of active ingredients in the agents according to the present invention can be between 0.1 and 50 g, preferably between 1 and 30 g of active substance per liter of treatment liquid, depending on the intended use.
By combining the compounds to be used according to the invention with surface-active, in particular washing-active substances, detergents and cleaning agents with an excellent antibacterial or antimycotic effect are obtained.
The detergents and cleaning agents can be used in any, z. B. liquid, pasty, solid, flaky or granular form. The agents according to the invention can be mixed with anionic compounds such as soaps and other carboxylates (e.g. alkali salts of higher fatty acids), derivatives of sulfur-oxygen acids (e.g. sodium: salt of dodecylbenzenesulfonic acid, water-soluble salts of sulfuric acid monoesters of higher molecular weight alcohols or their polyglycol ethers, such as soluble salts of dodecyl alcohol sulfate or of dodecyl alcohol polyglycol ether sulfate), derivatives of phosphorus oxygen acids (e.g. phosphates), derivatives with acidic (electrophilic) nitrogen in the hydrophilic group (e.g. disulfine salts), as well as with cationic surfactants , such as amines and their salts (e.g.
Lauryl diethylenetriamine), onium compounds, amine oxides or nonionic surfactants, polyhydroxy compounds, surfactants on a mono- or polysaccharide basis, higher molecular weight acetylene glycols, polyglycol ethers (e.g. polyglyl ethers, higher fatty alcohols, polyglycol ethers, polyglycol ethers are formulated from differently alkylated phenols with higher molecular weight). Their antimicrobial effectiveness is fully retained. The active ingredient content of the washing and cleaning agents, based on the weight of this agent, is generally 0.01 to 5%, mostly 0.1 to 3%. Aqueous preparations of such detergents and cleaning agents are also suitable as antimicrobial cleaning agents in the food and beverage industry, e.g. B. Breweries, dairies, cheese factories and slaughterhouses.
Furthermore, the agents according to the invention can also be used as cosmetic preparations, such as. B. essential oils, bath salts, brilliantines, ointments, facial tonics, hair dyes, hair oils, hair lotions, skin creams, skin oils, colognes, perfumes, powders, make-up, depilatories, sunburn products, dentifrices, etc., with which these preparations are additionally given an antimicrobial effect. In general, an active ingredient content of 0.01 to 5%, preferably 0.1 to 3%, based on the total weight of the preparations, is sufficient.
For disinfection and preservation purposes, the agents according to the invention can also be used in combination with already known antimicrobial agents. These include

Determination of the microbicidal effect
A. In order to determine whether the compounds of the formula I contained in the inventive agents as active ingredient have killed the test germs used in the above experiment (biocidal effect) or have merely inhibited their growth (biostatic effect), the inoculation sites of the germs that are not Show growth, place sterile filter paper discs with a diameter of 20 mm and, after a contact time of 30 minutes, transfer the germs by means of these discs to sterile agar blocked with Tween 80 for the active ingredients. The contact time is again 30 minutes.
If no growth of the transferred germs is observed on the secondary agar plate, the germs on the first plate have been killed by the active substance, i.e. H. the active ingredient has a biocidal effect on the germs tested in the relevant concentrations.
The following additional test is performed to confirm the above determination:
B. With active ingredients of formula I, solutions of the following composition are prepared: 5% active ingredient, 5% Na-N-cocos-ss-aminopropionate, 20% permutitol water,
70% ethyl cellosolve (ethylene glycol monoethyl ether).
Aliquots of these solutions are converted into emulsions of 1000 ppm, 500 ppm, 250 ppm and 125 ppm active ingredient content with sterile distilled water.
Samples of 9.9 ml of the emulsions are inoculated with 0.1 ml of germ suspensions (about 107 germs / ml).
Test organisms:
Staphylococcus aureus
Strephylococcus faecalis
Bacillus subtilis
Proteus vulgaris
After an exposure time of one minute, one oil from each of the inoculated emulsions is placed in 10 ml of sterile Brain Heart Infusion Broth, whereupon it is incubated for 24 hours at 37 and the Brain Heart Infusion Broth is then assessed for cloudiness (germ growth).
The tested compounds of the formula I showed a biocidal effect in the above tests.
