Method of diminishing urine odor and article functioning to diminish urine odor

Abstract

This invention relates to a method to decrease the urine fetid odor and a device to lower the urine fetid odor. The present invention provides a method to decrease the urine fetid odor by using a substance that reacts with aldehydes. Furthermore, the present invention relates to a device which comprises a substance that reacts with aldehydes to decrease the urine fetid odor, and in particular to a liquid absorbing device. The substance that reacts with aldehydes includes such as organic amines, organic amine salts, substance that reacts with excreta to generate organic amines, vinegar amine chemical compound, and chemical compounds containing hydrogen sulphur base.

Description

technical field [0001] The invention relates to a method for reducing urine odor and articles with the function of reducing urine odor. More specifically, the present invention relates to a method for reducing urine odor of body fluid-absorbent articles such as diapers, and a body fluid-absorbent article having a urine odor-reducing function. Background technique [0002] Bodily fluid absorbent articles such as paper diapers absorb excrement such as urine, and people are looking for countermeasures against the unpleasant odor generated when they are used or discarded after use. [0003] Many attempts have been made in the past to reduce urine odor, and the proposed methods include porous material adsorption method, bactericide method, and method of neutralizing odor components with acid or alkali. [0004] Most of them propose to utilize physical adsorption technology, for example, some use zeolite (Japanese Patent Opening Clearance 49-23493, Real Opening Clearance 55-75318...

AI Technical Summary

Problems solved by technology

[0005] However, there is a problem that the physical adsorption of porous substances, etc., has a limited adsorption capacity, and it is often possible to reversibly emit odors, and the deodorization speed is slow, and the absorbent article wets the micropores immediately after absorbing urine, etc. Adsorption capacity is also not effectively utilized, so its deodorizing effect is actually difficult to confirm

[0008] However, the present inventors have found that the smell of ammonia is not felt when the diaper is actually changed, and that the smell of urine does not disappear even though an antibacterial agent is added to fresh urine; In other words, the discomfort of urine odor when wearing and changing absorbent articles cannot be reduced by this method

[0009] In addition, for the purpose of deodorizing absorbent articles such as diapers, cation-exchange fibers having a deodorizing effect (JP-A-5-212094), deodorizing components containing pyrolignic acid (JP-A-9-276330), etc. have been proposed. proposal, but the status quo is that an effective countermeasure to eliminate unpleasant odors has not yet been found
