Embodiment Construction

[0006] The term "absorbent article" is used herein in a very broad sense and includes any article capable of receiving and / or absorbing and / or containing and / or retaining liquids and / or exudates, especially bodily fluids / exudates. An exemplary but non-exclusive absorbent article in the context of the present invention is a disposable absorbent article. The term "disposable" is used herein to describe articles that are not intended to be laundered, or otherwise stored or reused as articles (i.e. they are intended to be discarded after a single use and are preferably recycled, composted , or in other words in a manner compatible with the environment). Typical disposable absorbent articles according to the present invention are personal hygiene articles such as diapers, surgical and wound dressings and sweat pads, incontinence pads, and absorbent articles for feminine hygiene such as sanitary napkins, panty liners, vaginal tampons, interlabial devices, milk pads, etc. Absorbent...

Abstract

A composition for blocking blood-containing fluids is provided. The composition contains one or more hydratable non-deliquescent inorganic salts. In one embodiment, for example, the composition contains magnesium sulfate (MgSO 4 ). The composition may be placed in an absorbent core in an absorbent article to help block blood-containing fluids (e.g., menses exuded from the body).

Description

technical field [0001] The present invention relates to absorbent articles comprising hydratable insoluble inorganic salts that aid in the barrier of aqueous fluids containing blood, such as menses. Background technique [0002] Absorbent articles are known in the art. Typical examples for personal hygiene include sanitary napkins, panty liners, adult incontinence products, baby diapers, paper towels, toilet paper and facial tissues. Such articles are commonly used to absorb and retain bodily fluids and other exudates secreted by the human body. [0003] Fluid is often retained in absorbent articles within an absorbent element comprising absorbent material, often including superabsorbent material, such as absorbent gelling material (AGM), usually in finely divided form, such as usually in particulate form. Conventional superabsorbent materials known in the art for use in absorbent articles generally comprise water-insoluble, water-swellable, hydrogel-forming cross-linked a...
