    Abstract: Method for preparing an active-containing starch matrix and the free flowing, dry powder that results from such a process. The active ingredients can be released (deposited) onto a surface by normal triggering mechanisms, which include the action of a liquid or by friction or rubbing. The fixative systems described herein provide the ability to control high load levels and protection of the active while still being able to delivery this to a substrate when triggered. Additionally, ingredients incompatible and reactive with each other can be blended together as sold/used as a one piece system and no reactions will occur until the matrix is broken or triggered.
