Abstract
There is disclosed the process of incorporating a deodorant powder (of various mechanisms of action) into a hydrophilic, swellable, water-insoluble absorbent crosslinked polymer, which swellable polymer is coated on a thin, flexible, substrate e.g. a non-woven web, a paper tissue, or a water-insensitive film, and the resultant flexible structure which contain the deodorant powders, held in a dust-free stable manner, and their use as one or more components of body fluid absorbent structures such as sanitary napkins.
Claims1
A thin, flexible substrate in the form of a paper tissue or a water insensitive film, coated with a hydrophilic, water-insoluble, water-swellable cross-linked film forming polymeric material containing a powdered deodorant immobilized in a dust-free manner by being completely or partially encapsulated in said polymeric material.
