  • Publication number: 20140127309
    Abstract: The present invention meets one or more of the above needs and is a composition comprising plurality of capsules wherein the capsules comprise: a core of one or more highly polar liquids; one or more polar active materials dissolved in or dispersed in one or more highly polar liquids; a mixture of one or more polymers and one of more highly polar liquids; or a mixture of one or more polymers, one or more highly polar liquids and one or more polar active materials, and a shell comprising, particles in a polymer matrix or particles; wherein the thickness of the shell is sufficient to prevent passage of the highly polar liquid or the active material through the shell or to control the rate passage of the highly polar liquid or the active material through the shell with the proviso that the one or more polymers may be located in the core, in the polymer matrix of the shell or both.
