Patent ID: 10172974

Abstract:
In one aspect, compositions are described herein. In some embodiments, a composition described herein comprises the reaction product of (i) an alkoxylated or alkenoxylated citric acid, citrate, or ester of citric acid, and optionally a non-alkoxylated and non-alkenoxylated citric acid, citrate, or ester of citric acid, with (ii) a polyol. Additionally, in some cases, a composition described herein comprises the reaction product of (i) and (ii) above and (iii) one or more additional monomers. In some cases, the composition is cross-linked by the use of one or more oxidants such as sodium periodate (NaIO4) and/or silver nitrate (AgNO3), which can be reduced into a reduced oxidant that provides short-term antimicrobial activity. Such a composition can have both short-term and long-term antibiotic and antifungal activity.
