摘要:
A triggerable composition for two-stage, controlled release of a functional active chemical includes an encapsulation material for encapsulating a betaine ester or betaine ester derivative including a functional active. The encapsulation material is triggerable to release the betaine ester or betaine ester derivative at a first stage upon the occurrence with an environmental stimulus, such as a pH change, an enzymatic change, and a temperature change. The betaine ester or betaine ester derivative of a functional active with at least one hydroxyl group releases the functional active through a hydrolysis reaction upon contact with an aqueous medium.
