Abstract: An absorbent article having a void space for receiving bodily exudates comprises an elongate slit opening in communication with the void space. The elongate slit opening includes elasticated region disposed along longitudinal side edges of the slit opening which maintain longitudinal and lateral alignment and Z-direction proximity with a point of discharge on a wearer during use. The elasticated regions contain stored elastic energy producing tensile forces which are distributed laterally away from the slit opening enabling the edges to deflect and allow bodily exudates to pass through the slit opening to the void space.

Abstract: Absorbent article comprising an absorbent core with a crotch region and at least one waist region, whereby said crotch region has a lower ultimate fluid storage capability than at least one waist region. The article further has an improved fluid handling performance such as an acquisition rate of at least 0.6 ml in the fourth gush.

Abstract: A cleansing preparation is provided in the form of an oil-in-water emulsion. The oil phase particles have a median particle diameter by volume of not more than 1 &mgr;m, and a preservative is present in at least the aqueous phase. A method is described of making this preparation, in which a coarse emulsion is formed, the coarse emulsion is homogenized, and the homogenized emulsion is diluted by an aqueous dilution liquid containing the preservative. Cleansing articles, for example baby wipes can be made in which a substrate carries the cleansing preparation.

Abstract: The present invention relates to the selection of materials which are particularly useful as fluid distribution material for being used in disposable absorbent articles by being characterized in that they have a wicking time of less than 120 seconds and a cumulative flux of more than 0.075 grams/cm2/second for said preferential fluid distribution direction at 12.4 cm height, when applying the Vertical Wicking Test. A further useful selection criteria for such materials is a non-isotropic fluid distribution behavior, expressed in that the wicking time in the preferential distribution direction is less than 80% of the wicking time of perpendicular direction at 8.3 cm height, when applying the same test.
Abstract: An apertured polymeric film web having a first surface, a second surface generally parallel to and spaced apart from said first surface, and a plurality of fluid passageways extending between the first surface and the second surface to place the first surface and the second surface in fluid communication with one another. The web is formed of a polymeric film comprising at least one bulk modified layer, the bulk modified layer comprising a substantially homogeneous, stabilized dispersion comprising a comparatively low surface energy material in a polymeric material. The comparatively low surface energy material, referred to herein as a hydrophobic additive, imparts hydrophobicity to the web's first surface, thereby promoting enhanced effectiveness in transporting fluid away from the first surface of the web, particularly when used in combination with a hydrophilic adhesive applied to the web's second surface in a topsheet system of the present invention.

Abstract: Web materials which have two or more skin care compositions disposed thereon. The skin care compositions are transferable to the wearer's skin by normal contact and/or wearer motion and/or body heat. The skin care compositions disclosed in the present invention are selected to maintain and/or improve the skin health of the wearer upon transfer during use, for example, to provide a skin protective barrier or a therapeutic benefit; to minimize the abrasion between the cuffs and skin in the area where the cuffs contact the wearer's skin, resulting in less skin irritation; to improve BM clean up on the skin, or to improve the barrier properties of the cuffs. Web materials of the present invention have a wide range of potential uses in both durable and disposable articles, but are particularly well suited for use in disposable absorbent articles such as disposable diapers, incontinent briefs, training pants, sanitary napkins, and the like.

Abstract: An apertured, compression-resistant web is disclosed, the web comprising a first surface having a plurality of microapertures forming volcano-shaped surface aberrations, a second surface generally parallel to and spaced apart from the first surface. A plurality of fluid passageways extend between the first surface and the second surface to place the first surface and the second surface in fluid communication with one another. The web is formed of a multilayer polymeric film comprising at least one rigid layer and at least one substantially less rigid layer joined to the rigid layer. In a preferred embodiment, a rigid layer has an elastic modulus of at least 120 kpsi a substantially less rigid layer has an elastic modulus of not greater than 75 kpsi. The multilayer film is preferably formed by coextuding a rigid layer comprising a blend of polystyrene and polypropylene, and a substantially less rigid layer comprising a blend of LDPE and LLDPE.
Abstract: The present invention relates to wet wipes (1) for use in wiping surfaces in the home and in industry, in addition to their use on the human body such as for baby wipes, make-up removal and other skin care applications. The wet wipes are folded and interleaved with one another (40, 50) to provide an improved stacking configuration whereby each wipe can be readily singly separated from the wet wipe stack by the consumer.
