  • Publication number: 20060154378
    Abstract: The invention provides a facile method for measuring the leaching of encapsulated active ingredient from application media. This is achieved by separating a container by a membrane permeable to encapsulated material, but not to capsules; pouring a solution of the application medium into a first part of the container; pouring a solution of the application medium and encapsulated active ingredient into a second part of the container; allowing the solutions in both parts of the container to reach equilibrium; and measuring the concentration of the active ingredient in the first part of the container by directly injecting the solution into a Gas Chromatograph or High Performance Liquid Chromatograph.
