Pharmaceutical drug manufacturers have explored the use of biodegradable amphiphilic block copolymers for encapsulating APIs to improve their solubility in water and bioavailability, given the biodegradability and biocompatibility of these materials for drug delivery applications.

While previously employed in cosmetics for specialized purposes, the high cost and complex encapsulation process involving organic solvents posed challenges. Threessentials has addressed these hurdles by pioneering an economically feasible and sustainable encapsulation method utilizing block copolymers without the need for organic solvents, surfactants, alcohols, or high-energy inputs, thus democratizing access to this technology for mainstream users.
