METHOD OF PREPARING BIODECOMPOSABLE COMPOSITIONS BASED ON CELLULOSE ETHER

摘要

FIELD: chemistry. ^ SUBSTANCE: invention relates to a method of preparing compositions which are subject to biodecomposition based on methylcellulose, which can be used for cosmetic and medical purposes. The composition contains methylcelluose, a reagent for modifying rheological characteristics, a hygroscopic reagent and an antibacterial agent. The reagent for modifying rheological characteristics is selected from gelatine or casein. The hygroscopic reagent is selected from glycerine or polyethylene glycol. The antibacterial agent is silver nitrate. The composition also contains a plasticiser. The composition is prepared by mixing a colloidal gel of methylcellulose with the reagent for modifying rheological characteristics, the hygroscopic reagent and the antibacterial agent. ^ EFFECT: obtaining a composition for use as a cosmetic mask for skin or medical bandages and in production of packaging materials. ^ 2 cl, 2 ex
