Abstract
Vynález sa týká antimikrobiálného přípravku do emulgačných olejov a do emulzi! olejov s cidnymi účinkami voči baktériám, hubám a riasam. Antimikrobiálny prostriedok pozostáva zo zmesi formaldehydu a kvartérnych amoniových solí v hmotnostnom pomere 0,1 až 5 : 1, připadne ešte može obsahovat až do 75 % nmot. poloformálu alebo látky vytvárajúce poloformálThe invention relates to antimicrobial into emulsifying oils and into the emulsion! oils with bacterial action, hubs and algae. The antimicrobial agent consists of mixtures of formaldehyde and quaternary ammonium salts in a weight ratio of 0.1 to 5: 1, may still contain up to 75% nMot. semi-formal or substance forming a half-mold
Description
Má aj nedostatky, lebo je velmi pfchavý, podlieha oxidácii a tým v ďalšom sposobuje korózie materiálov.It also has drawbacks, because it is very volatile, subject to oxidation and thus causes further corrosion of materials.
V literatuře odporúčané i v praxi používané sú i niektoré tenzidy kationaktívneho typu. Medzi ne patří aj alkyl-dimetylbenzyl amoniumchlorid. Vyznačuje sa antimi krobiálnym účinkom voči širokému spektru grampozitívnych i gramnegatívnych baktérií, vláknitých húb, rias a kvasiniek. V praxi sa používá ako dezinfekčný alebo sanitárny čistiaci prostriedok, tiež pre ďalšie použitie ako protislizový prípravok vo vodných cirkulačných okruhoch, aj ako prípravok pre antimikrobiálnu úpravu textilných vláken. Ako dezinfekčný prostriedok sa používá v kon centráciách 1 až 5 g/1 vody. Napriek týmto odporúčaniam pri aplikácii do olejových emulzií v uvedených i vyšších koncentráciách nepreukázal požadovaný cídny účinok®Some surfactants of the cationic type are also recommended and used in the literature. These include alkyl dimethylbenzyl ammonium chloride. It is characterized by an antimicrobial effect against a wide range of gram-positive and gram-negative bacteria, filamentous fungi, algae and yeast. In practice, it is used as a disinfectant or sanitary cleaner, also for further use as an anti-slip agent in aqueous circulation circuits, as well as as an antimicrobial treatment for textile fibers. 1 to 5 g / l of water is used as a disinfectant. Despite these recommendations, when applied to oil emulsions at the above and above concentrations, it did not demonstrate the desired cure effect.
Vyššie uvedené nedostatky sú odstránené antimikrobiálnym prípravkom do emulgacných olejov a do emulzií olejov s cídny mi účinkami voči baktériám, hubám a riasam, ktorého podstatou je , že pozostáva zo zmesi formaldehydu a kvartérnych amoniových solí všeobecného vzorca (I)The above-mentioned drawbacks are eliminated by an antimicrobial preparation for emulsifying oils and for emulsions of oils having a beneficial effect on bacteria, fungi and algae, which consists of a mixture of formaldehyde and quaternary ammonium salts of the general formula (I)

Antimikrobiálny prípravok može ďalej obsahovat až do 75 %hmot. poloformálu alebo 2átky vytvárajuce poloformál.The antimicrobial composition may further comprise up to 75% by weight of the composition. or a semi-formal substance.
Takýto prípravok má dlhotrvajúcu posobnost. Je nekorozívny a jeho účinok v porovnatelných koncentráciach je podstatné vyšší. Použitím biocídu podlá vynálezu spolu so známými biocídnymi látkami ako sú poloformály (poloacetáty) sa zvyšuje cídna účinnost zmesi.Such a formulation has a long-lasting flexibility. It is non-corrosive and its effect at comparable concentrations is substantially higher. The use of a biocide according to the invention together with known biocidal substances such as semi-forms (semi-acetates) increases the overall effectiveness of the composition.
