Biodegradable polyesteramines for sustainable high-performance cleaning systems
Introducing biodegradable polyesteramines, synthesized from bio-based diacids and amino alcohols, offering a sustainable alternative to polyquaterniums. These polymers ensure superior deposition and biodegradability, aligning with global sustainability goals.
Overview
The University of North Texas BioDiscovery Institute presents innovative biodegradable polyesteramines designed for high-performance cleaning systems. These polymers are synthesized through the polycondensation of bio-based diacids, such as succinic acid, and amino alcohols like N-methyldiethanolamine. The resulting biodegradable polyesteramines offer an eco-friendly substitute for traditional polyquaterniums, featuring a robust positive charge and exceptional deposition capabilities on diverse surfaces. This solution not only enhances cleaning efficiency but also supports environmental sustainability with over 60% biodegradability within 28 days.
