Abstract
Herein we describe a method for the reduction of pollution in aquatic systems by incorporating polyhydroxyalkanoate microbeads into personal care formulations such as exfoliants, cosmetics, and toothpaste. Suitable polyhydroxyalkanoate microbeads are biodegradable, have an average size of less than 400 microns, and sink rapidly in aquatic environments.
