Biodegradable polymer dispersion for controlled infusion and slow release of hydrophobic ingredients
Developing biodegradable, water-dispersed polymer systems for short-life coatings that can incorporate and slowly release hydrophobic active ingredients. The approach uses soft biodegradable hydrophobic polymers with film-forming behavior at 50–55% solids, enabling uptake of over 10% hydrophobic liquids. Optional use of hollow inorganic carriers under 5 µm can increase load capacity. Intended for controlled-release coating applications and further dispersion and release-threshold testing.
Overview
The solution focuses on developing biodegradable polymer dispersions for short-life coatings. The polymers are designed to incorporate hydrophobic active ingredients and enable slow release when applied as a coating. Using soft biodegradable hydrophobic polymers dispersed in water, the system achieves film-forming capability at solid concentrations of 50–55%. This formulation supports uptake of more than 10% of hydrophobic active liquids, enabling gradual release of the active ingredient after coating.
