ABSTRACT:
The present invention describes a means for fixing skin care ingredients on the surface of non-woven webs and cellulosic mats. The active ingredients can be released (deposited) onto the skin by normal triggering mechanisms, which include the action of water or urine or by friction or rubbing. The fixative systems described herein provide the ability to control high load levels while not interfering with the wettabliity of the fabric or paper. Additionally, incompatible/reactive ingredients can be treated onto the same web and are kept as separate particles fixed to the surface until released.
