Encapsulation of oleophilic substances and compositions produced thereby
摘要:
Multiple micro-encapsulations of a high concentration oleophilic substance using heat to set the primary particle renders the composition suitable for the production of free-flowing powders or beadlets. Microencapsulation involves forming an emulsion out of the oleophilic substance and a polymer, and then use heat setting and/or cross-linking the polymer encapsulates the oleophilic composition. This process is then repeated with a second polymer or third polymer, and with or without cross-linked via the same or different mechanism to further protect the oleophilic substance.
