Safety assessment of shoe insoles treated with various biocidal compositions

The article deals with the study of the antimicrobial activity of shoe insoles treated with biocidal compositions . Antimicrobial treatment was carried out in distilled water using the following chemical agents: polyvinyl alcohol (PVA), salicylic acid (SA), copper sulfate, urea, polyvinylpyrrolidone (PVP), benzoic acid. The antimicrobial activity of the modified materials was determined against test cultures - E. coli and molds p.Penicillium. It was found that the studied samples of shoe insoles have a stable antibacterial effect - the growth inhibition zone is from 2 mm to 4 mm, but there is no fungal resistance.
