Abstract: An antimicrobial polymer composition comprising: (i) about 0.1 wt. % to about 50 wt. % of efficacy enhancing poly (isobutylene-co-maleic anhydride) polymer functionalized with (a) at least one pseudo cationic agent selected from the group consisting of functionalized and unfunctionalized primary, secondary or tertiary amines, (b) at least one compound selected from functionalized and unfunctionalized C1 to C12 alcohols and (c) at least one hydrophobic moiety selected from functionalized and unfunctionalized C4 to C20 amines; (ii) about 0.1 wt. % to about 50 wt. % of at least one neutralizing agent for enhancing efficacy of said polymer; and (iii) about 0.1 wt. % to about 99.9 wt. % of delivery system comprising at least one solvent. Also disclosed is a process for preparing the antimicrobial compositions and methods of use thereof.

Abstract: What is described herein is a synergistic preservative composition capable of providing broad spectrum antimicrobial activity comprising: (i) about 0.1 wt. % to about 99.9 wt. % of propylene carbonate; (ii) about 0.1 wt. % to about 99.9 wt. % of one or more organic compounds, and wherein, inclusion of each additional organic compound is capable of demonstrating cumulative synergistic effect; and (iii) optionally about 0.1 wt. % to 99.0 wt. % of one or more preservative compounds, and wherein, inclusion of each preservative compound is capable of demonstrating cumulative synergistic effect, wherein the Synergy Index (SI) value of the total composition is from about 0.05 to about 0.95. Also described is a process for preparing said composition and method of use of the same.
