The present inventions relates to a disposable absorbent articles, including diapers and sanitary napkins, comprising a bleach activator system for controlling odors associated with bodily fluids. The bleach activator system may comprise a peroxygen bleach compound (including a source of hydrogen peroxide) and a bleach activator compound capable of generating a peroxyacid in-situ within the absorbent article.

Disposable absorbent articles comprising odor controlling materials

This invention is directed to a process for making solid, typically particulate, water-swellable material comprising coated water-swellable, preferably hydrogel-forming polymers, which are coated with a coating agent, which is such that it does not rupture when the polymers swell in a liquid, e.g., water or saline water. Hereto, the coating agent is extensible in wet state and comprises thereto a wet-extensible material that has a tensile stress at break in the wet state of at least 1 MPa. Typically, the coating agent comprises thereto an elastomeric polymeric material. The invention also relates to solid (particulate) water-swellable material obtainable by the process of the invention.

Process for making water-swellable material comprising coated water-swellable polymers

An absorbent article may comprise a topsheet, a backsheet joined with the topsheet, an absorbent core interposed between the topsheet and backsheet; and one or more article elements selected from the group consisting of an anal cuff, an elasticized topsheet, a fastening system, a leg cuff, a waist elastic feature, a side panel, an ear, and combinations thereof. The article elements may comprise a slow recovery stretch laminate exhibiting an unload force at 37&#xb0; C. of about 0.16 N/(g/m) or greater and a percent of initial strain after 15 seconds of recovery at 22&#xb0; C. of about 10% or greater.

Absorbent articles comprising a slow recovery stretch laminate

This invention is directed to coated water-swellable materials, typically solid, particulate, water-swellable materials, i.e. materials that comprise hydrogel-forming polymers, whereof at least a part is coated with a coating, which substantially does not break when the polymers swell, as set out in the method herein. Said coating is present at a level of at least 1% by weight of the water-swellable material. The coating comprises preferably an elastomeric polymeric material. The invention also relates products, e.g., disposable absorbent articles, comprising such coated water-swellable material.

Coated water-swellable material comprising hydrogel forming polymers

An absorbent article comprising at least one topsheet; a liquid impervious backsheet joined with the topsheet; an absorbent core interposed between the topsheet and backsheet; and a slow recovery elastomer. The slow recovery elastomer exhibits a normalized unload force at 37&#xb0; C. of greater than about 0.04N and at least about 20% post elongation strain at 22&#xb0; C. after 15 seconds of recovery.

Absorbent articles comprising a slow recovery elastomer

This invention is directed to a process for making solid, typically particulate, water-swellable material comprising coated water-swellable, preferably hydrogel-forming polymers, which are coated with a coating agent, which is such that it does not rupture when the polymers swell in a liquid, e.g., water or saline water. Hereto, the coating agent is extensible in wet state and comprises thereto a wet-extensible material that has a wet-elongation of at least 400%, or even more preferably at least 500%, and preferably a tensile stress at break in the wet state of at least 1 MPa. Typically, the coating agent comprises thereto an elastomeric polymeric material. The invention also relates to solid (particulate) water-swellable material obtainable by the process of the invention.

Coated water-swellable material

This invention is directed to absorbent structures and preferred absorbent articles, comprising solid, typically particulate, water-swellable material that comprises coated water-swellable, preferably hydrogel-forming polymers, which are coated with a coating agent, which is such that it does not rupture when the polymers swell in a liquid, e.g., water or saline water. Hereto, the coating agent is extensible in wet state and comprises thereto a wet-extensible material that has a tensile stress at break in the wet state of at least 1 MPa. Typically, the coating agent comprises thereto an elastomeric polymeric material.

Coated water-swellable material comprising hydrogel-forming polymeric core and polymeric coating agent

This invention is directed to an absorbent structure comprising a solid, typically particulate, water-swellable material that comprises coated water-swellable, preferably hydrogel-forming polymers, which are coated with a coating agent, which is such that it does not rupture when the polymers swell in a liquid, e.g., water or saline water. Hereto, the coating agent is extensible in wet state and comprises thereto a wet-extensible material that has a wet-elongation of at least 400% or even at least 500%, and preferably a tensile stress at break in the wet state of at least 1 MPa. Typically, the coating agent comprises thereto an elastomeric polymeric material.

Absorbent article comprising coated water-swellable material

Disclosed are thin until wet materials that are suitable for use as acquisition members for absorbent articles (e.g., diapers, catamenial products, and adult incontinence devices). Preferred materials according to the present invention are either: 1) fibrous assemblies that utilize wet strength means to stabilize the material or 2) compressed regenerated cellulosic sponges so that, when the material is saturated with an aqueous fluid, it has an expanded wet density of between about 0.04 grams/cm and about 0.4 grams/cm and an expanded capillary desorption height of less than about 25 cm and a temporary binding means that helps maintain the material at a compressed dry density between about 0.06 grams/cm and about 1.2 grams/cm until the material is exposed to an aqueous fluid. The ratio of the compressed dry density to the expanded wet density is also greater than about 1.5:1. A suitable process for making the materials and absorbent structures using the materials are also disclosed.

Thin until wet structures for acquiring aqueous fluids

This application relates to microporous, open-celled polymeric foam materials with physical characteristics that make them suitable for a variety of uses produced from high internal phase emulsions (HIPEs). This application particularly relates to oxidatively stable emulsifiers used to stabilize the HIPE and the foams produced from such HIPEs.
