Abstract
Disclosed are articles useful in cleansing, and particularly wet-like cleansing wipes and toilet tissue. These articles are essentially dry to the touch prior to use, but deliver liquid when subjected to in-use shear and compressive forces. In one aspect, the articles of the present invention comprise a carrier and an emulsion applied to the carrier, the emulsion comprising a continuous external nonpolar phase and an internal polar phase dispersed in the external nonpolar phase, wherein the article is capable of retaining fluid prior to use. In another aspect, the emulsion-treated articles exhibit improved ability to release fluid when subjected to in-use pressures. The articles of the present invention offer a number of significant advantages over prior cleaning products when in the form of wet-like cleansing wipes such as those used for cleaning of hardsurfaces (e.g., floors, countertops, sinks, bathtubs, toilets, and the like) and wet-like toilet tissue. The articles can in general be used in any applications requiring the delivery of polar materials, in particular water and water-soluble or dispersible actives.
