Starch Granule Encapsulation Carrier
CAS Number: 9005-25-8
Modified corn or tapioca starch is used as a biodegradable granule carrier and encapsulation matrix in soil-applied pesticide granules (GR) and slow-release formulations. Starch provides a controlled-release matrix through physical encapsulation of active ingredients, moderating their release rate in soil environments and reducing leaching and runoff risks. As a natural polymer, starch-based carriers support biodegradable formulation strategies and meet the growing demand for environmentally responsible agrochemical products.
