Abstract: A detergent composition having a plasma-induced, water-soluble coating for controlling solubility, chemical stability, and physical properties is disclosed. A process for making such a detergent composition is also disclosed which involves subjecting a detergent material to a plasma glow zone in which an organic hydrophilic monomer is introduced such that it ultimately deposits on the detergent material to form a water-soluble coating. The detergent compositions are particulate or non-particulate and can be used for laundry, dishwashing, or other similar applications.

Abstract: A dispenser for moist tissue is provided including a housing formed of two housing sections for a moist tissue roll and a dispenser slit having a stepped inner surface configuration. The dispenser is positioned for use on a vertical or horizontal surface by supports attached to a housing section.
Abstract: Granular detergent compositions and in particular low density, phosphate containing detergent compositions comprise a specific bleaching system containing hydrophobic peracid bleach and hydrophilic peracid bleach and a peroxide source. These detergent compositions have specific low levels of available oxygen from hydrophobic aid hydrophilic peroxyacid bleach, specific ratios of available oxygen from the hydrophobic peracid bleach to the hydrophilic peracid bleach and specific ratios of available oxygen of the peroxide source to the available oxygen of the peracids. These specific mixed bleach systems are useful for sanitization or reduction of bacterial activity.

Abstract: The present invention discloses dry effervescent granules comprising an acid, carbonate source and optionally a binder, wherein said acid, carbonate source and optionally binder are in close physical proximity. The invention also discloses granular compositions, containing effervescence material comprising an acid and a carbonate source, which has an effervescence index (EI) of at least 50. The granular compositions may be obtainable by incorporating said pre-formed dry effervescent granules into said granular compositions, especially detergent compositions. Improved effervescence is obtained when diluting these granular detergent compositions with water to obtain a washing/soaking liquor, resulting thereby in improved dissolution/dispensing characteristic and improved stain removal performance on soiled fabrics.

Abstract: A composition having a plasma-induced, graft polymerized, water-soluble coating for controlling solubility, chemical stability and physical properties is disclosed. A process for making such a composition is also disclosed which involves subjecting a particulate material to plasma after which a water-soluble organic monomer is graft polymerized onto at least a portion of the particulate material. The compositions are particulate or non-particulate in form and can be used in shampoos, skin care and other cosmetic products, deodorant products, laundry, dishwashing, or other similar detergent products.
Abstract: The present invention relates to a flushable fibrous structure that is particularly useful as a disposable tissue product and as a component (e.g., topsheets) for absorbent articles such as catamenial pads, diapers, incontinent articles and the like. The invention specifically relates to a flushable fibrous structure that has an in-use wet tensile strength of at least about 100 g/in. and a disposal wet tensile strength of not more than about 30 g/in. The invention also relates to absorbent articles comprising the fibrous structures, and methods for making the structures.

Abstract: A lotion composition for imparting a soft, lubricious, lotion-like feel when applied to tissue paper in amounts as low as from about 5 to about 15% by weight, and tissue paper treated with such lotion compositions are disclosed. The lotion composition comprises plastic or fluid emollient such as petrolatum, or a mixture of petrolatum with alkyl ethoxylate emollient, an immobilizing agent such as a fatty alcohol or fatty acid to immobilize the emollient on the surface of the tissue paper web and optionally a hydrophilic surfactant to improve wettability when applied to toilet tissue. Because less lotion is required to impart the desired soft, lotion-like feel benefits, detrimental effects on the tensile strength and caliper of the lotioned paper are minimized or avoided.

Abstract: The present invention is directed to a box (10) for containing tissues, comprising at least one opening (11) located on at least one side of the box, under which a dispensing insert (14) is positioned so that it covers at least partially said opening of the box, said dispensing insert further comprising a cut-out portion (15) or a dispensing slot with at least two portions (16) that contact the border of the box opening, said box being characterized in that the dispensing insert is made out of material with high resilience, so that after being bent it is capable of coming back to its initial shape on its own, without losing its elastic properties.
Abstract: A dispenser for moist tissue is provided including a housing formed of two housing sections for a moist tissue roll, a dispenser slit having a stepped inner surface configuration and a retaining latch. The retaining latch limits the degree of opening of the housing sections which are joined by a hinge. The dispenser is positioned for use by two arms attached to a housing section.
Abstract: Paper products having high initial wet strengths are disclosed. The paper products comprise cellulosic fibers having free aldehyde groups, which fibers are combined with a water-soluble polymer having functional groups that are reacted with the aldehyde groups to form bonds joining the fibers.
In a preferred embodiment, the cellulosic fibers contain a polysaccharide in which the hydroxyl groups of at least a portion of the repeating units of the polysaccharide are cis-hydroxyl groups, preferred repeating units being mannose and/or galactose. Similarly, the water-soluble polymer is preferably a polysaccharide in which the hydroxyl groups of at least a portion of the repeating units of the polysaccharide are cis-hydroxyl groups. Preferred polysaccharides are derived from one or more sugars selected from mannose, galactose, allose, altrose, gulose, talose and lyxose.

Abstract: An absorbent article, such as a diaper, containing cuffs with a skin care composition disposed thereon. The skin care composition disposed on the cuffs is transferable to the wearers skin by normal contact and/or wearer motion and/or body heat. The cuffs are at least partially assembled using an oil resistant adhesive that is both material friendly and process friendly.

Abstract: Tissue paper webs useful in the manufacture of soft, tissue products such as wipes and facial tissues, and processes for making the webs are described. The tissue paper webs include papermaking fibers, an antimigration material and an emollient lotion. Preferred antimigration materials include quaternary ammonium compounds. Preferred emollient lotions include a hydrocarbon emollient. The preferred process for making the preferred invention includes providing the antimigration material to the papermaking furnish and depositing the emollient lotion onto at least one surface of the dried tissue web that includes an antimigration material.
