Inventors: E Model, 3 Bindler and R Zinkernagel Priority begard feat September 8, 1958 and August 18, 1959 (Switzerland) The present invention relates to a process for protecting organic materials of all kinds against microorganisms using a microorganism-feeding agent, and the agent itself and a material protected according to the procedure.
Det har visat sig, att man kan skydda organiska material av alla slag mot mikroorganismer, cm man behandlar dessa material med en verksam amneskombination, som bestar av minst ett mikroorganismcloclande verksamt amne tillhorande en klass av foreningar med den allmanna formeln A R1—N N—R 2 \(I) NH• och minst ett mikroorganismclodande amne tillInirande en klass av foreningar med den allmanna formeln 4 /\/NH\ I (Hal). IC=0(II) 7 I dessa formler betecknar Ri en lipofil grupp av 10-14 kolatomer eller en lipofil grupp innehallande aralifatisk rest, R, vate eller en alifatisk grupp med 1-4 kolatomer. A en genom a, .- eller a, y-kolatomer fOrenad alifatisk eller en genom a, fl-kolatomer forenad cykloalifatisk rest, Hal en halogenatom och n 0, 1, 2, 3 eller 4. R1 betecknar exempelvis en. dekyl-, dodekyl-, tetradekylgrupp eller en 4-dodekylbensylgrupp. Flireningar med den allmanna formeln I, van i R1 betecknar en dodekyl- eller tetradekylgrupp, arc att foredraga. It has been found that one can protect organic materials of all kinds against microorganisms by treating these materials with an active compound combination, which consists of at least one microorganism-cleaving active substance belonging to a class of compounds of the general formula A R1-NN-R 2 \ (I) NH • and at least one microorganism clodding substance forming a class of compounds of the general formula 4 / \ / NH \ I (Hal). IC = 0 (II) 7 In these formulas, R 1 represents a lipophilic group of 10-14 carbon atoms or a lipophilic group containing araliphatic radical, R, vate or an aliphatic group having 1-4 carbon atoms. A is an aliphatic aliphatic compound represented by α, eller or α, γ-carbon atoms or a cycloaliphatic radical united by α, β-carbon atoms, Hal has a halogen atom and n has 0, 1, 2, 3 or 4. R 1 represents, for example, a. decyl, dodecyl, tetradecyl group or a 4-dodecylbenzyl group. Flirins of the general formula I, used in R1 represent a dodecyl or tetradecyl group, are preferred.
R, betecknar exempelvis en metyl-, etyl-, n-propyl-, isopropyl- eller en n-butylgrupp; fbreningar med den allmanna formeln I, van i R, betecknar vate, aro emellertid att fOredraga. Som vid a, kolatomerna forenade alkylenrester A ifragakomma exempelvis 1,2-etylen-, 1,2-propylen-, 1,2- eller 2,3-butylenresten, som analogt bundna cykloalkylenrester exempelvis 1,2-cyklohexylenresten eller 3- eller 4-mety1-1,2-cyklohexylresten. Som vid a,y-kolatomerna bundna alkylenrester A kunna exempelvis namnas 1,3-propylen-, 1,3-butylen-, 1,3- eller 2,4-pentylenresten. Sadana foreningar med den allmanna formeln I, van i A betecknar en 1,2-etylenrest, arc att foredraga. Hal betecknar i den allmanna formeln II forctradesvis klor eller brom. Vad den fungicida verkan betraffar, har sadana amnessammanstallningar visat sig vara bast lampade, i vilka som verksamma amnen med formeln II inga 5,6-diklor-2,3-dihydrobensoxazol-2-on eller 4,5,7-triklor-2,3-dihydrobensoxazol-2-on. R 1 represents, for example, a methyl, ethyl, n-propyl, isopropyl or an n-butyl group; compounds of the general formula I, van i R, denote vate, however, are to be preferred. As in the case of a, the carbon atoms combined alkylene radicals A are used, for example, 1,2-ethylene, 1,2-propylene, 1,2- or 2,3-butylene radical, as analogously bound cycloalkylene radicals, for example 1,2-cyclohexylene radical or 3- or 4 -methyl-1,2,2-cyclohexyl radical. As alkylene radicals A bonded to the α, γ carbon atoms, for example, the 1,3-propylene, 1,3-butylene, 1,3- or 2,4-pentylene radical can be mentioned. Such compounds of the general formula I, used in A, represent a 1,2-ethylene residue, which is to be preferred. Hal in the general formula II preferably denotes chlorine or bromine. As far as the fungicidal action is concerned, such compound formulations have been found to be highly lamped, in which as active substances of the formula II no 5,6-dichloro-2,3-dihydrobenzoxazol-2-one or 4,5,7-trichloro-2, 3-dihydrobenzoxazol-2-one.
De verksanuna substanserna med formel I kunna anvandas som sadana eller i form av sina salter med syror, exempelvis som hydroklorider eller hydrobromider, eventuellt aven under tillsats av attiksyra. Viktforhallandet verksamt amne med formeln I till verksamt amne med formeln II ut- lampligen 1: 1 till 4: 1. The active substances of formula I can be used as such or in the form of their salts with acids, for example as hydrochlorides or hydrobromides, optionally also with the addition of acetic acid. The weight ratio of active substance of formula I to active substance of formula II is approximately 1: 1 to 4: 1.
Den fungicida verkan av 2,3-dihydrobensoxazol-2-oner ãr visserligen kand (jamfor Virtanen, Acta Chemica Scandinavica, 12, (1958) 124-128, Nr. 1). ii.vensâ är den fungicida och baktericida verkan av vissa dialkylerade 2-imino-1,3-di-Nheteroeykler kand. Verksamma amnessammanstallningar enligt foreliggande uppf inning visa dock, isynnerhet i ovan angivna viktforhallanden, en fungicid verkan, som overtraffar summan av de fungicida verkningarna hos de enskilda komponenterna. Tack vane denna synergistiska effekt uppnar man ett onskat resultat med en betydligt mindre koncentration av den verksamma 2— — amnessammanstaningen i bararmaterialet an vid anvandning av de enskilda komponenterna. De baktericida och algicida egenskaperna hos de definitionsenliga 2-imino-1,3-N-heterocyklerna bibehallas helt i de verksamma amneskombinationerna enligt uppfinningen. HSr och i det foljande taIas om »fungicith eller »baktericid» verkan aven for det fall det eventuellt endast är fraga om »fungistatisk» eller »bakteriostatisk» verkan. The fungicidal action of 2,3-dihydrobenzoxazol-2-ones is admittedly well known (cf. Virtanen, Acta Chemica Scandinavica, 12, (1958) 124-128, No. 1). ii.vensâ is the fungicidal and bactericidal action of certain dialkylated 2-imino-1,3-di-Nheteroeykler kand. However, active amnesic compositions according to the present invention show, in particular in the above weight ratios, a fungicidal effect, which exceeds the sum of the fungicidal effects of the individual components. Due to this synergistic effect, a desired result is obtained with a much smaller concentration of the active compound in the bar material than in the use of the individual components. The bactericidal and algicidal properties of the 2-imino-1,3-N-heterocycles defined by definition are fully maintained in the active amnesic combinations of the invention. HSr and hereinafter referred to as "fungicite or" bactericidal "action even in the case where it may only be a question of" fungistatic "or" bacteriostatic "effect.
En ytterligare vardefull egenskap hos de verksamma amnessammanstallningarna Sr deras goda vattenloslighet resp. dispergerbarhet. Detta Sr overraskande, emedan de uppfinningsenligt anvandbara 2,3-dihydro-bensoxazol-2-onerna enbart for sig aro svarhisliga i vatten. Det Sr en stor for-del hos de verksamma amnessammanstallningarna enligt uppfinningen, att de aro anvandbara som vattenhaltiga eller organisk-vattenhaltiga losningar. Som organiska losningsmedel ifragakomma I forsta hand sadana som aro blandbara med vatten, exempelvis etanol eller etylenglykolmonometyl- eller etyleter. De verksamma vattenhaltiga eller vattenhaltigt-organiska amneslosningarna enligt uppfinningen hro latt applicerbara pa organiska material, framforallt pa textiHer, exempelvis p5 textilier av ylle, siden, bomull eller av acetylcellulosa, polyamid-, polyakrylnitril- eller polyesterfibrer, varvid de ph fibrer, vilka icke sjalva aro utsatta for mikrobiskt angrepp, verka som skydd for angripbara klister och mjukningsmedel. An additional valuable property of the active amnesic compositions Sr their good water solubility resp. dispersibility. This is surprising, since the 2,3-dihydro-benzoxazol-2-ones usable according to the invention alone are black in water. It is a great advantage of the active amnesic compositions according to the invention that they are useful as aqueous or organic-aqueous solutions. Suitable organic solvents are primarily those which are miscible with water, for example ethanol or ethylene glycol monomethyl or ethyl ether. The active aqueous or aqueous-organic bead solutions according to the invention are readily applicable to organic materials, in particular to textiles, for example to textiles of wool, silk, cotton or of acetylcellulose, polyamide, polyacrylonitrile or polyester fibers, the ph fibers which are not themselves aro exposed to microbial attack, act as protection against attackable adhesives and plasticizers.
Den basta verkan erhalles genom impregnering med sadana amnessammanstallningar, vilka lanehalla de ovan definierade verksamma amnena i viktfOrhallandet 2: 1 till 3: 1. Koncetrationen av den verksamma hmnessammanstallningen i losningen uppgar med fordel till minst 0,5 promille. Som losningsmedel Sr vatten att foredraga. Det genom impregneringen med de uppfinningsenliga amnessammanstallningarna erhallna skyddet av ovan anforda material omfattar exempelvis skydd mot Fusarium oxysporum, Aspergillus niger, Ctenomyces interdigitalis, Penicillium expansum, Stachybotris atra, Chaetonium globosum on mot vissa bakterier on alger. The best effect is obtained by impregnation with such amnesic compositions, which contain the active ingredients defined above in the weight ratio 2: 1 to 3: 1. The concentration of the active amnesic composition in the solution advantageously amounts to at least 0.5 per mille. As a solvent Sr water is preferred. The protection of the above-mentioned materials obtained by the impregnation with the amnesic compositions according to the invention includes, for example, protection against Fusarium oxysporum, Aspergillus niger, Ctenomyces interdigitalis, Penicillium expansum, Stachybotris atra, Chaetonium globosum and against certain bacteria and algae.
De verksamma amneskombinationerna enligt uppfinningen kunna icke endast anvandas i form av deras vattenhaltiga eller vattenhaltigt-organiska losningar, utan Oven blandade med andra inerta barare eller fyllmaterial, exempelvis med rengoringsmedel, kosmetiska eller medicinska preparat, med andra biocida eller med insekticida medel o.s.v. och narmare bestamt i pulverform, som hisningar eller som dispersioner. Da de icke endast aro losliga i alkoholer, utan Oven i andra organiska losningsmedel, sasom exempelvis i alifatiska eller aromatiska klorerade eller oklorerade kolvaten, sasom bensen, toluen, klorbensen eller dikloretylen, lampa sig Oven for anvandning i torrengoringsmedel samt for framstallning av s.k. »Sprays* for rumsdesinfektion. (I dessa fall anvander man komponenten I lampligen i form av dess fria bas). Man kan dessutom inblanda dem pappersbehandlingsbad eller tryckfortjockningar av starkelse eller cellulosaderivat eller anvanda dem for impregnering av tra. Men polyvinylklorid-preparat, exempelvis folier, samt hacker och malarfarger, vilka framstallts jiS kaseinbasis eller innehalla kasein, och jamval oorganiska material som exempelvis Melilotuspulver, bibringas med den uppfinningsenliga verksamma amneskombinationen ett verksamt skydd mot mikroorganismangrepp. Dessutom kunna amnessammanstallningar enligt uppfinningen Sven med framgang anvandas for skydd av fotterna mot svampangrepp, t. ex. genom behandling av skodon, av inlaggssulor eller av strumpor fOr tillintetgorande av infektionshardar eller for profylax. Den baktericida och algicida verkan av sammanstallningarna enligt uppfinningen stracker sig exempelvis till stafylokocker, coli-, paratyfusoch enteritisbakterier. Dessa mangsidiga egenskaper hos de nya fungicida och baktericida medlen mojliggOra en anpassning av anvandningsformen efter de foreliggande forhallandena. SOlunda kan man exempelvis vid sarbehandling anvanda saval dessa verksamma amneskombinaHoner innehalland.e salvor, puder och fOrbandsmaterial, som Oven tvattvatskor i form av vattenhaltiga eller vattenhaltigt-alkoholiska losningar av dessa medel. :Men for desinfektion av instrument, verktyg och installationstillbehor aro de uppfinningsenliga medlen lampliga. Slutligen ma Sven namnas anvandningen i kosmetiska preparat. The active amnesic combinations according to the invention can be used not only in the form of their aqueous or aqueous-organic solutions, but also mixed with other inert carriers or fillers, for example with detergents, cosmetic or medicinal preparations, with other biocides or with insecticides and so on. and more specifically in powder form, as elevators or as dispersions. Since they are not only soluble in alcohols, but also in other organic solvents, such as, for example, aliphatic or aromatic chlorinated or chlorinated hydrocarbons, such as benzene, toluene, chlorobenzene or dichloroethylene, they are also suitable for use in dry cleaners and for the preparation of so-called »Sprays * for room disinfection. (In these cases, component I is suitably used in the form of its free base). They can also be mixed with paper treatment baths or pressure thickeners of starch or cellulose derivatives or used for impregnating wood. However, polyvinyl chloride preparations, for example foils, as well as hacker and paint paints, which are made from a casein-based or casein-containing material, and from inorganic materials such as Melilotus powder, are provided with the active amine combination according to the invention as an effective protection against microorganism attack. In addition, amnesia compositions according to the invention can be successfully used to protect the feet from fungal infestation, e.g. by treating footwear, insoles or socks for the destruction of infectious cures or for the prophylaxis. The bactericidal and algicidal action of the compositions according to the invention extends, for example, to staphylococci, coli, paratyphoid and enteritis bacteria. These multifaceted properties of the new fungicidal and bactericidal agents make it possible to adapt the form of use to the present conditions. Thus, for example, in the case of special treatment, these active amnesic combinations containing ointments, powders and dressings may be used, as well as wash water shoes in the form of aqueous or aqueous-alcoholic solutions of these agents. : But for disinfection of instruments, tools and installation accessories, the means according to the invention are suitable. Finally, Sven must mention the use in cosmetic preparations.
