Abstract
The present invention relates to personal cleansing wipes articles which have superior softness, feel and cleansing properties. The wipes of the present invention comprise a substrate and an aqueous liquid cleansing composition which is coated onto or impregnated into said substrate to the extent of from about 100% to about 400% by weight of the substrate. The substrate is a single-layer, nonwoven substrate which is formed from hydroentangled fibers. Upon a substantial portion of a base surface comprising the substrate there exists a three-dimensional pattern comprising a plurality of discrete, raised fibrous regions. The raised fibrous regions have a density which is substantially the same as the density of the base surface. The raised fibrous regions are joined to the base surface by a fibrous transition region. The aqueous liquid cleansing composition comprises an effective amount of a cleansing surfactant.
