ABSTRACT:
Cyclic siloxanes that contain releasable active ingredients are described. The active ingredient can be an alcohol or enolizable carbonyl-containing compound such as a ketone, aldehyde, or ester. The product siloxanes are useful in a variety of personal and household care products where slow or controlled release of active ingredient is desired. A preferred embodiment utilizes substituents that when released as active ingredients are fragrant.
