Problems solved by technology

[0010] However, although so-called deodorants show a certain degree of deodorizing effect by chemical reaction or adsorption of odorous components, it is usually not confirmed that they are very effective in deodorizing unpleasant odors of urine, nor can they suppress Decomposition or spoilage of organic matter caused by microorganisms or fungi
On the other hand, although so-called antibacterial agents can suppress bad odors caused by decomposition or putrefaction, they cannot be confirmed to be very effective in deodorizing newly excreted urine
In addition, only some general deodorant compounds are added to ordinary water-absorbent resins. When such water-absorbent resins are used in absorbent articles such as paper diapers, it may not be necessary to impart deodorant performance to the entire diaper. fully
[0011] Therefore, the above-mentioned conventional method for improving deodorization may not be able to exert sufficient effect in actual use, and it cannot be said to be ideal for absorbent articles using a water-absorbent resin produced by the conventional method.

Embodiment approach 1

[0040] First, a description will be given of a water absorbent composition obtained by combining a semi-fermented tea extract and / or a fermented tea extract, a surface-treated water absorbent resin, and / or a water absorbent resin having specific physical properties.

[0041] In the embodiment of the present invention, the water-absorbent resin refers to a polymer that is cross-linked only inside, and / or a polymer that is cross-linked inside and on the surface. In particular, the so-called surface-treated water-absorbent resin refers to a polymer that is cross-linked inside and on the surface.

[0042] As the water-absorbent resin in this embodiment, a water-absorbent resin having the following characteristics (i) and / or (ii) is used:

[0043] (i) It is preferable that the surface portion and / or its peripheral portion is surface-treated with a cross-linking agent (that is, the surface portion and / or its peripheral portion are cross-linked by a cross-linking agent obtained by re...

Embodiment approach 2

[0123] The following describes a particulate water-absorbing agent composition (particulate water-absorbing resin composition) having three characteristics of (1) a specific neutralization rate; (2) a specific particle diameter; and (3) a specific plant component.

[0124] First, the water absorbent resin used in this embodiment will be described.

[0125] (I) Water absorbent resin

[0126] The water-absorbent resin used in this embodiment is a water-swellable water-insoluble cross-linked polymer that can form a hydrogel. For example, the so-called water-swellability means that it must be able to absorb more than 5 times its own weight in ion-exchanged water, A large amount of water of 50 times to 1000 times is preferred; their determination methods are in accordance with the provisions of the examples.

[0127] As the water-absorbent resin in this embodiment, it is necessary to use a water-absorbent resin (A) having a cross-linked structure obtained by polymerizing an acid g...

Embodiment 1～7 and comparative example 1～7

[0224] Take out 50ml from the human urine mixture collected by 10 adults, and add it to a 120ml polypropylene cup with a cover (manufactured by Tera Oka Co., Ltd., pack エエ一ス, caliber (mm) × lower diameter (mm) × height (mm) = 58×54×74), and then add 2.0 g of water-absorbing resin (or water-absorbing agent composition) to form swelling gel. The human urine is the human urine within 2 hours after excretion. Cover the container, keep the swelling gel at 37°C, and open the lid after 1 minute (initial) and 3 hours and 6 hours after absorbing the liquid, and place a group of 20 adults at a position about 3cm from the upper part of the cup Smell the odor to judge the deodorizing effect.

[0225] The judgment is based on: 1 no odor; 2 almost no odor; 3 perceivable but tolerable odor; 4 strong odor; 5 strong odor. value. The same operation as above was performed on a cup containing no water-absorbing resin (or water-absorbing agent composition) and only human urine, as a standard pr...

Abstract

A water-absorbent composition includes: a specific plant extract; a water-absorbent resin whose surface portion and / or periphery thereof is treated; and / or a water-absorbent resin having a specific property. Specifically, it is preferable to use a water-absorbent resin having three characteristics: (1) a specific neutralization rate, (2) a specific particle diameter, and (3) a specific plant extract. The water-absorbent composition has a superior deodorant performance and an absorbent characteristic when the water-absorbent composition is used (provided) in an absorbing product such as a paper diaper, thereby providing a superior deodorant performance and a superior absorbent characteristic to the foregoing absorbing product.

Description

technical field [0001] The present invention relates to a water absorbent composition, a method for producing the same, an absorbent body, and an absorbent article. More specifically, the present invention relates to a hygienic material having particularly excellent deodorizing (taste) performance and excellent absorption characteristics when used in an absorbent body of hygienic material, and imparting particularly excellent deodorizing performance and excellent absorption characteristics to said hygienic material. The water-absorbing agent composition of the absorption characteristic and its production method, absorbent body and absorbent article, and the hygienic material is disposable diaper, sanitary napkin, incontinence liner and the like. Background technique [0002] In recent years, water-absorbent resins have been used as one of the constituent materials (main constituent materials) in sanitary materials (absorbent articles) such as disp...
