Cellulose materials modified by antiseptics and their antimicrobial properties

Adsorption properties of dressing cellulose materials with respect to surfactant antiseptics were studied. These antiseptics are a complex of the copolymer of N-vinylpyrrolidone and crotonic acid with dimethylbenzylalkylammonium chloride (a synthetic polymer with a wide spectrum of antimicrobial effect) and its low molecular weight analogue (dimethylbenzylalkylammonium chloride). It was established that cellulose materials reversibly adsorb mentioned surfactant antiseptics depending on their concentration in the initial solutions. Maximum release of surfactant antiseptics is achieved at solutions at pH = 7.0. Microbiological tests of cellulose materials modified by antiseptics have shown that they exhibit antimicrobial activity. These results can be used in medical practice in clinics for imparting antimicrobial properties to dressing materials.
