Silica microcapsules, each of which includes a shell, and a core containing one or more organic compounds inside the shell, a softener composition containing the silica microcapsules, and a method of producing the silica microcapsules is described. In the silica microcapsules, the shell contains silica as a constituent component, and the organic compound contains a primary alcohol.

The present invention relates to nanocapsules, nanocapsule substrate mixtures and processes of making and using same. Such nanocapsule substrate mixtures can provide biological articles such as teeth, bones, and tissues as well as nonbiological articles such as ceramics and polymers, with self-healing capabilities and/or antimicrobial properties. Applicants' nanocapsules allow for a high packing density as well as good mechanical and physical properties that provide the desired performance in each desired application.

Disclosed is a composition including controlled release particles, wherein each of the controlled release particles includes: (a) a core including at least one hydrophobic active ingredient; and (b) a wall at least partially surrounding the core and including: (i) an organofunctional silane; (ii) an epoxy; (iii) an amine; (iv) an isocyanate; (v) an epoxide curing agent; wherein the controlled release particles are effective to retain the at least one hydrophobic active ingredient upon exposure to water and effective to release the at least one hydrophobic active ingredient in response to friction. A method for preparing the composition is also disclosed.
