Preservative compositions comprising renewably-based, biodegradable 1,3-propanediol

Abstract

Disclosed herein are preservative compositions comprising 1,3-propanediol, wherein the 1,3-propanediol in said composition has a bio-based carbon content of about 1% to 100%. In addition, it is preferred that the 1,3-propanediol be biologically-derived, and wherein upon biodegradation, the biologically-derived 1,3-propanediol contributes no anthropogenic CO2 emissions to the atmosphere.
