The invention relates to the use of a urease inhibitor in an absorbent article to maintain the pH of the wearer's skin in a range of 4.0 to 6.0, wherein the urease inhibitor is provided between the topsheet and the absorbent core and/or is provided in the absorbent core. The invention also relates to absorbent articles comprising a urease inhibitor.

The present invention protects a disposable hygienic article characterized in that it has a formulation that promotes the skin care through the use of natural compounds such as the cane wax extract, which has pharmacological properties such as healing and anti-inflammatory, the formulation may also contain agents that helps neutralize unpleasant odors such as chlorophyll, an antimicrobial agent such as grapefruit seeds extract and a fragrance.

[Problem] To provide an absorbent article further suppressing occurrence of malodor after absorbing body fluid,

[Solution] An absorbent article comprising a liquid permeable top sheet disposed on a skin surface side, a liquid impermeable back sheet disposed on an external surface side, and at least one water absorbent layer disposed between the top sheet and the back sheet, wherein the water absorbent layer includes a water absorbent resin powder, a deodorizing sheet supporting a polyphenol compound is disposed closer to the skin surface side than the back sheet, and a metal ion is substituted for a part of hydrogen atoms of phenolic hydroxy groups of the polyphenol compound.

The present disclosure relates to an absorbent article having a topsheet, a backsheet, an absorbent core, and a polyol and a urease inhibitor and methods for making the same.

The present disclosure relates to method for making an absorbent article comprising the step of applying a solution comprising a solvent and a urease inhibitor to the absorbent article and an absorbent article comprising a soluble urease inhibitor.

A method of manufacturing an absorbent article includes a paper making step in which, after forming a wet paper sheet from a source material and adding a fragrance material to the wet paper sheet, a pulp raw fabric sheet is obtained by dehydrating and drying the wet paper sheet; and a processing step of an absorbent article in which the pulp raw fabric sheet is defibrated and an absorbent body is manufactured by fiber stacking this defibrated fluff pulp.

The present disclosure relates, according to some embodiments, to an absorptive solid (e.g., an animal bedding) produced from a microcrop such as Lemna. An absorptive solid of the present disclosure may comprise (i) an odor-absorbing amount of chlorophyll, and (ii) a carbohydrate extracted from a microcrop, the carbohydrate itself comprising at least some of the odor-absorbing amount of chlorophyll. A process for generating an absorptive solid may comprise the actions of: (i) lysing a microcrop consisting of at least one photosynthetic aquatic species to generate a lysed microcrop; (ii) separating the lysed microcrop into a solid fraction and a juice fraction; (iii) separating the solid fraction to form a solid; and at least one of: (a) milling the solid to generate an absorptive powder, (b) shaping the solid to generate the absorptive pellet or an absorptive granule; and (c) extruding the solid to generate an absorptive extrudate.

A skin patch for delivering scent to a human nose includes a flexible base member configured to be adhered between a base of the nose and a vermillion border. The flexible base member defines an outer perimeter having a left edge, a right edge, an upper edge extending from the left edge to the right edge, and a lower edge opposite the upper edge and extending from the left edge to the right edge. The flexible base member includes a first side and a second side opposite the first side, the second side including a skin contact adhesive. A plurality of perforations through the flexible base member extend from the first side to the second side. The perforations are distributed across the flexible base member. A non-perforated section of the flexible base member carries a scented portion.

The present disclosure relates, according to some embodiments, to methods and systems for deriving odor- and moisture-absorbing products from a microcrop (e.g., photosynthetic aquatic species). More specifically, the present disclosure relates, in some embodiments, to forming an absorptive product from Lemna, including an animal litter, an animal bedding, a diaper product, a spill clean-up product, and any combination thereof. A process for forming an absorbent product from a microcrop may comprise the actions of (a) lysing the microcrop to generate a lysed microcrop; (b) separating the lysed microcrop into a solid fraction and a juice fraction; (c) processing the solid fraction to generate an absorbent solid; and/or (d) forming, by a shaping unit, the absorbent solid into pellets or granules that may be incorporated into the absorptive product. An absorptive product may have odor-reducing properties that are due in part to chlorophyll (e.g., from a microcrop).

A contact efficiency between a fragrance material and body fluid is increased, fragrance is effectively generated by a small amount of the fragrance material, and a manufacturing step is simplified.

Including an absorbent body (6) in which a defibrated fluff pulp (5), defibrated from a pulp raw fabric sheet (4), is fiber stacked, wherein a fragrance material (3) is added to the pulp raw fabric sheet (4) before being defibrated. A manufacturing method includes a paper making step of obtaining, after forming a wet paper sheet (2) from a source material (2) and adding a fragrance material (3) to the wet paper sheet (2), a pulp raw fabric sheet (4) by dehydrating and drying the wet paper sheet (2), and a processing step of an absorbent article of defibrating the pulp raw fabric sheet (4) and manufacturing an absorbent body (6) by fiber stacking this defibrated fluff pulp (5).
