  • Publication number: 20120023693
    Abstract: A cleaning pad has a facing layer joined to a backsheet, and an absorbent core disposed between the facing layer and backsheet. The facing layer is an integral sheet having a first region comprising a plurality of apertures, and a second region comprising a plurality of raised protrusions. The two different regions provide dual functionalities of absorbing (or distributing) liquid, such as a cleaner, and scrubbing, respectively.

  • Patent number: 7179007
    Abstract: The present invention provides a semi-enclosed applicator for distributing a substance onto a target surface. The applicator has a first side, a second side, and an internal cavity between the first and second sides. The applicator further includes at least one opening, such that the internal cavity is externally accessible, and the applicator further comprises: (a) a material comprising absorbent and substantially non-absorbent fibers on one of the first and second sides; (b) an absorbent core on the other of the first and second sides; and (c) a substantially fluid-impervious barrier layer within the internal cavity adjacent the absorbent core. The applicator includes at least one opening, such that the internal cavity is externally accessible, and the applicator further comprises: (a) a substantially fluid-impervious barrier layer within the internal cavity adjacent one of the sides; and (b) a rupturable fluid-containing reservoir located between the barrier layer and the side.

  • Patent number: 6753063
    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.

  • Patent number: 6149926
    Abstract: The present invention relates to cosmetic applicators comprised of a sheet of porous or absorbent material which is impregnated with an oil-in-water emulsion composition. The oil-in-water emulsion compositions comprises an oil phase comprising from about 0.1% to about 5% by weight of the emulsion composition of an oil-soluble moisturizing agent, dispersed in an aqueous phase. The oil-soluble moisturizer has a mean particle size ranging from about 0.05 to about 7 microns. The oil-in-water emulsion comprises from about 0.1% to about 5% by weight of the emulsion of a surfactant and from about 0.05% to about 5% by weight of the emulsion of particulates. The viscosity of the oil-in-water emulsion composition ranges from about 1 to about 500 centipoise.
