HYGIENIC PRODUCT WITH ANTIMICROBIAL AND ANTIFUNGAL PROPERTIES Russian patent published in 2011 - IPC A61L15/16 B82B1/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine and hygiene, particularly, to hygienic products showing adsorbent properties in relation to various liquids. The hygienic product with antimicrobial and antifungal properties contains at least one adsorbent layer in the form of a dry cellulose mass produced by water system treatment of biocide based on bentonite powder nanoparticles intercalated by silver (Ag⁺) and/or copper (Cu^{2 +}) ions and at the amount of metal in the powder 2.0-8.0 wt %. The cellulose mass is flaked cellulose of the density 100-800 kg/m³. A copolymer of the molecular weight 3000 to 500000 based on hydrolysed vegetable protein with silanol groups or polyvinylpyrrolidone engrafted to end or lateral amino groups is additionally introduced in the biocide water system . The treatment process requires the following proportions of copolymer: bentonite powder: water: flaked cellulose, as (4·10^-3-15·10^-3):(4·10^-3-15·10^-3):(0,5:2,5):1 (weight fractions), and in the equal proportions of copolymer: bentonite powder in the water system.

EFFECT: hygienic product under the invention has effective service characteristics of adsorption time, absorption capacity of the adsorbent layer and prolonged antimicrobial and antifungal action.
