Токсико-бактеріологічні властивості нового дезінфікуючого засобу "Аеросан"
The article presents the test results of studying of toxicological and bacteriological peculiarities of new home disinfectant Aerosan containing active substances such as benzalkonium chloride, polyhexamethyl -eneguanidine and hydrogen peroxide. The toxicity parameters of native and working solutions of disinfectant were provided. The results concerning the efficacy of disinfectant in respect to museum microorganism strains, bactericidal dilution, bactericidal concentration and phenol coefficient were demonstrated. The conducted tests showed that according to State Standard 12.1.007-76 native solution of disinfectant belongs to the 2<sup>nd</sup> class of toxicity (highly toxic substances) and working solution - to the 4<sup>th</sup> one (less toxic substances). It was determined that bactericidal concentration of disinfectant at exposure of 10 and 30 minutes was equal 0.37 and 0.27% for E.coli and for S.aureus - 0.72 and 0.52 %, respectively. The bactericidal dilution of disinfectant concerning test-culture is slightly higher in comparison to bactericidal dilution of phenol and average phenol coefficient was 1.39 units for E.coli and 1 - for S.aureus. It was demonstrated that disinfectant Aerosan possesses high disinfective peculiarities in vitro to test cultures E.coli and S.aureus and can be applied for conducting of wet and aerosol disinfection of animal husbandries.
