Microencapsulated delivery vehicle having an aqueous core
 
Amundson et al of Kimberly-Clark, Wisconsin, developed a microencapsulated delivery vehicle suitable for use in personal care products, such as wet wipes. This includes an aqueous core of an encapsulating activator, a matrix material, such as water, and an active agent that may or may not be surrounded by a hydrophobic wax material.  A surfactant is introduced into a liquid solution containing a crosslinkable compound.  Once in the liquid solution, the encapsulating activator reacts with the crosslinkable compound to form an encapsulation layer that surrounds the aqueous core composition.  After a sufficient time has passed, the encapsulated aqueous core composition containing the active agent is removed from the liquid solution.  The encapsulated aqueous core may then be subjected to one or more further processing steps to introduce additional layers of encapsulation onto the formed shell.  These layers may include, for example, a moisture protective layer to reduce the potential for deactivation of the active agent due to leaking of the agent from the capsule into the product, and a fugitive layer to impart mechanical strength to the capsule.
