  • Composition comprising an iodide and a derivative of hyaluronic acid with an oxidative effect, method of preparation thereof and use thereof
    Patent number: 11425907
    Abstract: An antimicrobial composition is provided. The composition comprises a chloramid of hyaluronic acid or of modified hyaluronic acid. The chloramid has an amidic group (—NH—CO—). The hydrogens of the amidic group are substituted by chlorine atoms according to the structural formula —NCl—CO—. The composition further comprises an iodide. The substitution degree of the hyaluronic acid or of the modified hyaluronic acid by chlorine is in an amount of from 50% to 100%.

  • ANTIMICROBIAL COMPOSITION COMPRISING A POLYSACCHARIDE, A STABILIZING AGENT AND TRIIODIDE, METHOD OF PREPARATION THEREOF AND USE THEREOF
    Publication number: 20200179445
    Abstract: A composition having antimicrobial activity is provided. The composition comprises a polysaccharide, a stabilizer, and a triiodide, where the triiodide decomposition to iodide and volatile iodine can be significantly suppressed by the presence of the stabilizer. Methods of preparing and using the composition and devices prepared therewith are also disclosed. As compared to liquid forms comprising triiodide, stabilized solid forms can be used for a much wider range of applications due to their shape stability and a significantly smaller volume and weight of total material.
