Definitions

  • the present invention relates to a combination of a carrier material and a preparation which contains a quaternary ammonium compound (QAV) as an antimicrobial active ingredient, in particular a quaternary ammonium impregnated cleaning substrate for surface disinfection while avoiding the carryover of microorganisms.
  • QAV quaternary ammonium compound
  • cleaning substrates impregnated with an antimicrobial composition are used.
  • the cleaning substrates are used in the form of wipes, fleeces, sponges or mops and consist of cellulose-containing fibers, fibers of synthetic polymers or composite materials of these fibers.
  • antimicrobial agents for surface disinfection peroxide-containing compounds aldehydes, guanidines or quaternary ammonium compounds are known.
  • cleaning substrates may be impregnated with the antimicrobial solutions and stored in suitable containers until needed, especially for cleaning substrates in the form of cleaning wipes
  • a disadvantage is that they accelerate the decomposition or adsorption of the active ingredients used, for example, WO 2009/138888 describes the accelerated degradation of peroxide- and peracid-containing substances when cellulose-containing moist wipes are impregnated with these substances
  • WO 2009/138888 describes the accelerated degradation of peroxide- and peracid-containing substances when cellulose-containing moist wipes are impregnated with these substances
  • a hydrophobic substrate containing synthetic melt-extrudable polymers is recommended.
  • EP 2 443 925 describes the use of surface disinfecting substrates which are produced from polypropylene.
  • EP 2 443 924 describes the use of synthetic materials as a substrate to reduce the adsorption of antimicrobial agents.
  • the synthetic materials are preferably polypropylene and polyethylene terephthalate.
  • EP 1 661 586 mentions that wipes used for surface disinfection and consisting predominantly of cellulose-containing fibers can not fully provide the desired disinfecting performance, since the antimicrobial active substance, especially if they are quaternary ammonium compounds, is present in one adsorbed considerable extent. It is concluded that the adsorption of conventional disinfectants can be reduced by the use of plastic cloths made of special plastic materials. In this case, this effect should be particularly pronounced in disinfectant solutions containing quaternary ammonium compounds, as they have a particularly strong tendency to mount on cellulose-containing fibers.
  • the object of the present invention was therefore to provide a substrate for effective surface disinfection while reducing cross-contamination.
  • Another advantage of the present invention is reduced cost in the manufacturing process of the cleaning substrates when cellulosic based materials can be used.
  • the wiping tests are carried out over four fields (so-called "4-field test"), whereby only the first field is contaminated with testing organisms
  • the exposure time t is at least 1 minute and at most either 5 minutes or 60 minutes
  • An exposure time of no more than 5 minutes is selected if the cleaning substrate to be tested is intended to disinfect surfaces in contact with patients and / or Candida albicans Medical personnel may come or are frequently touched by different people, which can lead to the transmission of microorganisms to the patient.
  • fields 1-4 are run over within one second at a unit weight applied to the standard cloth or cleaning substrate to be tested.
  • the unit weight is turned over and the four fields are crossed in reverse order within the next second.
  • the detection of colony-forming units (CFU) from each of the test fields 1-4 is carried out by cotton swab method according to EN 16615: 2015.
  • the reduction R is calculated.
  • the number of surviving cells at the end of the reaction time t for the cleaning substrate to be tested (N a ) is compared with the values of the control experiment.
  • the control value Da is determined by drying the same aliquot of inoculum on a separate test area and determining the number of test organisms after the corresponding time t.
  • the germ reduction is then given in logarithmic values and is calculated according to the following equation
  • the logarithmic value obtained for R is referred to as the reduction factor RF.
  • the carrier material of the cleaning substrates according to the invention consists of a cellulose-based substance and a plastic.
  • the cellulose-based material may be pulp, cotton or viscose.
  • the plastic is selected from the group of polyolefins.
  • the polyolefin may be a polymer of ethylene, propylene, 1-butene and / or isobutene, preferably polypropylene.
  • a particularly preferred embodiment is a carrier material of polypropylene and viscose.
  • the carrier materials may be in the form of nonwovens, textile fabrics, wipes, mops or sponges.
  • the antimicrobial agents used according to the invention are quaternary ammonium compounds (QAC).
  • QAVs are benzalkonium chloride, didecyldimethylammonium chloride, dioctyldimethylammonium chloride, tetradecyldimethylethylammoniumethosulfate, benzyl-C 12-16 -alkyldimethylammonium chloride, C 12-14 -alkyl [(ethylphenyl) methyl] dimethylammonium chlorides, cetrimonium bromide, cetrimonium chloride, cetylpyridinium chloride (1-hexadecylpyridinium chloride ), Didecylmethyl (oxyethyl) ammonium propionate, decylisononyldimethylammonium chloride and meconium acetyl sulfate.
  • Particularly preferred is a mixture of didecyldimethylammonium chloride, benzyl-Ci2-i6-alkyldimethylammonium chloride and C 12-14 - Alkyl [(ethylphenyl) methyl] dimethylammonium chloride used as an antimicrobial agent, which is sold as a solution in isopropanol (16/16/16) under the trade name Bardac ® .
  • the abovementioned carrier materials are preferably impregnated with aqueous or aqueous-alcoholic solutions of the QACs. Particular preference is given to using aqueous isopropanol, n-propanol and / or ethylhexylglycerol solutions, the alcohol content usually being from 0.1 to 15, preferably from 1.0 to 10,% by volume.
  • the impregnation of the carrier materials can be carried out immediately before use or else the cleaning substrates, preferably in the form of wipes, are stored after impregnation in suitable containers until use (so-called "ready-to-use" cleaning substrates).
  • the efficiency of the combination according to the invention in the disinfection of surfaces and prevention of carryover of microorganisms can be checked as follows.
  • the content of QACs in the combinations according to the invention is determined after one week of storage at room temperature (23 + 2 ° C.) by pressing out the impregnated cleaning substrates and subsequent measurement of the active ingredient content in the collected solution.
  • the content of active substance was determined beforehand directly in the solution containing the quaternary ammonium compounds.
  • the content of QACs when using a solution of didecyldimethylammonium chloride, benzyl-C 12-16 -alkyldimethylammonium chloride and C 12-14 -alkyl [(ethylphenyl) -methyl] dimethylammonium chloride is determined by potentiometric two-phase titration (Titrino 721, from Metrohm).
  • Teitrino 721 Surfactrode Resistant from Metrohm and as reference electrode Double Junction from Metrohm, which is filled with a 0.4 molar tetraethylammonium bromide solution (Metrohm), is used as the electrode.
  • the titration is carried out against a solution of 0.004 mol / L sodium dodecyl sulfate.
  • the salary is calculated as follows:
  • a cleaning substrate which may consist of 45% polypropylene and 55% viscose impregnated with a solution of didecyldimethylammonium chloride, benzyl-C 12-16 -alkyldimethylammonium chloride and C 12-14 -alkyl [(ethylphenyl) methyl] dimethylammonium chloride
  • the cleaning substrates which consist of a combination of quaternary ammonium compounds with cellulose and polyolefin-containing substrates, can be used for the disinfection of surfaces. They are particularly suitable for the disinfection of inanimate surfaces. The effectiveness in the surface disinfection is checked against the standard cloth, which was also soaked with QACs, according to EN 16615: 2015.
  • the determination of the respective number of colony-forming units was carried out by plating a 0.5 ml aliquot from the dilution stages 10 °, 10 "1 and 10 " 2 on CSA (casein soybean meal peptone agar) and subsequent incubation at 36 + 1 ° C. To determine the reduction factor of the cleaning cloth (RF cloth), this value obtained is also compared with the value of the control experiment (Da).
  • the box comes with a lid locked.
  • the pure drug solution and after a 1 week the hand-squeezed out of the tissues solution is examined.
  • the 200 wipes stored at room temperature 23 + 2 ° C are removed from the can. Subsequently, the two ends of the roll of cloth are rotated against each other and collected the solution expressed thereby in a screw jar.
  • the 15 cloths stored at room temperature of 23 + 2 ° C are removed from the glass and the 15 cloths are pressed out by hand through a funnel and the solution is collected.
  • the solutions are investigated with regard to their active ingredient content as described in Example 1.
  • the standard cloth has an active ingredient loss of 74.36% (see Fig. 1).
  • Example 3 The effectiveness of the cloths impregnated with a solution of didecyldimethylammonium chloride, benzyl-C 12-16 -alkyldimethylammonium chloride and C 12-14 -alkyl [(ethylphenyl) methyl] dimethylammonium chloride, which consist of 45% PP and 55% viscose, or with this solution impregnated standard cloth, is determined in the quantitative germ carrier test according to EN 16615: 2015 against the test organism Pseudomonas aeruginosa. Recoverable colony-forming units are detected after surface disinfection with one of the two cloths to be tested on the four test fields.
  • Tab.l Effectiveness of a cleaning cloth made of 45% PP and 55% viscose compared to a standard cloth in surface disinfection according to EN 16615: 2015 and reduction of the colony-forming units in the cloths after completion of wiping, impregnation with a solution of didecyldimethylammonium chloride, benzyl -Ci2-i6-alkyldimethyl-ammonium chloride and Ci2-i4-alkyl [(ethylphenyl) methyl] dimethylammonium chloride
