Abstract
Pre-moistened wiping articles are provided comprising a fibrous web impregnated with a liquid cleaning composition including an unstable dispersion of water, surfactant, and water insoluble polysaccharide particles such as natural starch and/or microcrystalline cellulose. Due to the instability of the dispersion the particles primarily reside on the surface of the fibers forming the fibrous web and are freely released from the web as a result of the mechanical and hydraulic forces associated with use of the article. The pre-moistened wiping articles are suitable for use in personal care applications including use as perineal wipes. Embodiments of the invention further include methods of making pre-moistened wiping articles comprising a fibrous web impregnated with the unstable dispersion.
