Эффективность изучали на культуре кишечной палочки E. coli. Определено оптимальное процентное соотношение химического состава для получения ДС на основе альдегидов, аминов, хлорсодержащих веществ: дидециламмоний хлорид -9,8%; глутаровый альдегид -9,7%; глиоксаль 7,7%; дистиллированная вода 66,8%; вспомогательные компоненты – 6%. Выявлено, что наибольшее влияние на эффективность дезинфектанта оказывают парные взаимодействия компонентов, а не содержание компонентов по отдельности. Исключение составляет дистиллированная вода. При соблюдении указанных условий, гибель E. сoli составляет 98,1±1,6% (найдено в эксперименте). Теоретически рассчитанное значение (по уравнению) составило 95,4%. Отклонение экспериментально найденной величины от теоретической составило 2,75%, что свидетельствует об адекватности модели.Изучение нового сконструированного дезинфицирующего средства (ДС) позволило сделать заключение об эффективности для: St. аureus ATCC 6538, начиная с концентрации 0,25% при экспозиции 60 минут; Y. pestis EV и V. cholerae 0I 75-М в концентрации не менее 2% экспозиции 60 минут; C. аlbicans АТСС 10231 в концентрации 0,5% при воздействии 15 минут; B. anthracis Ценковского 4% раствор экспозиция 60 минут. ДС по степени воздействия на организм, токсичность относится к 3 классу умеренно опасных веществ при введении в желудок и 4 классу малоопасных веществ при нанесении на кожу.</p></abstract><trans-abstract xml:lang="en"><p>This article discusses the effect of the concentration of active components on the effectiveness of disinfectants with using of the rotatable central compositional design of the experiment. Efficacy studied on E. coli culture. There was determinate optimal percentage of the chemical composition for obtaining disinfectants based on aldehydes, amines, chlorine-containing substances: Didecylammonium chloride -9.8%; Glutaraldehyde -9.7%; glyoxal 7.7%; distilled water - 66.8%; auxiliary components - 6%. It was found that the greatest influence on the effectiveness of the disinfectant is exerted by the pairwise interactions of the components and not the content of the components separately. The exception is distilled water. Under these conditions, the death of E. coli is 98.1 ± 1.6% (found in the experiment). The theoretically calculated value (according to the equation) was 95.4%. The deviation of the experimentally found value from the theoretical was 2.75%, which indicates the adequacy of the model.The study of a new designed disinfectant allowed us to conclude that it is effective for: St. аureus ATCC 6538 starting at concentration of 0, 25% with an exposure of 60 minutes; Y. pestis EV и V. cholerae 0I 75- М at concentration of at least 2% of the exposure for 60 minutes; C. аlbicans АТСС 10231 at a concentration of 0.5% when exposed to 15 minutes; B. anthracis Tsenkovsky 4% solution for 60 minutes. DS according to the degree of exposure to the body, toxicity belongs to the 3rd class of moderately hazardous substances when introduced into the stomach and the 4th class of low-hazard substances when applied to the skin.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дезинфицирующие средства</kwd><kwd>антисептические препараты</kwd><kwd>токсичность</kwd><kwd>умеренно опасные вещества</kwd><kwd>эффективность дезинфектанта</kwd></kwd-group><kwd-group xml:lang="en"><kwd>disinfectants</kwd><kwd>antiseptic drugs</kwd><kwd>toxicity</kwd><kwd>moderately dangerous substances</kwd><kwd>the effectiveness of the  disinfectant</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Гельфанд Б.Р.
