  • Encapsulation of oleophilic substances and compositions produced thereby
    Patent number: 6150086
    Abstract: 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.
    Type: Grant
    Filed: November 12, 1999
    Date of Patent: November 21, 2000
    Assignee: Roche Vitamins Inc.
    Inventors: Stasia Boyle, Kuei-Tu Chang
