Deodorizer Composition for Absorbent Articles Without Yellowing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing absorbent articles using silver zeolite for odor control exhibit insufficient deodorant performance and yellowing over time, particularly when exposed to high humidity and temperature.
Innovation Solution
A deodorant composition combining silver zeolite with an organic antimicrobial and a water-absorbent resin, which suppresses yellowing and enhances deodorant performance, especially when retained at 70±2°C and 90±2% relative humidity for up to 3 days.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If silver zeolite is used as a deodorant component, then deodorant performance is improved, but the composition turns yellow over time
Solution Approach 1:
The patent combines silver zeolite with organic antimicrobial agents and water-absorbent resins to create a composite deodorant composition. This composite structure allows the silver zeolite to provide deodorant functionality while the other components suppress yellowing, resolving the contradiction between maintaining deodorant performance and preventing discoloration.
Solution Approach 2:
The organic antimicrobial agent acts as an intermediary substance that suppresses the yellowing effect of silver zeolite. By introducing this intermediate component, the harmful yellowing property is controlled while the beneficial deodorant performance is preserved.
2Reliability
If deodorant composition is retained at high temperature and humidity, then deodorant performance is maintained, but yellowing accelerates
Solution Approach 1:
The patent converts the harmful effect of high temperature and humidity (which accelerate yellowing) into a beneficial testing condition. By evaluating yellowing resistance under these accelerated conditions, the composition is optimized to maintain deodorant performance while resisting yellowing even when exposed to such environments during actual use.
Solution Approach 2:
The patent modifies the chemical composition parameters by incorporating specific organic antimicrobial agents and water-absorbent resins that change the overall properties of the deodorant composition. These parameter changes enable the material to resist yellowing under high temperature and humidity conditions while maintaining deodorant effectiveness.
3Device complexity
If silver zeolite is used without organic antimicrobial, then composition is simpler, but deodorant performance is insufficient
Solution Approach 1:
The patent merges silver zeolite with organic antimicrobial agents and water-absorbent resins into a unified deodorant composition. This combination creates a synergistic effect where the organic antimicrobial enhances the deodorant performance of silver zeolite, justifying the increased compositional complexity through improved functional reliability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition maintains effective deodorant performance while preventing yellowing, reducing ammonia generation, and improving odor control in absorbent articles like diapers and sanitary materials.
Implementation Method 1
silver zeolite and an organic antimicrobial are jointly used... better deodorant performance can be exhibited
Implementation Method 2
deodorant composition containing silver zeolite, an organic antimicrobial, and a water-absorbent resin... when retained at a temperature of 70±2° C. and a relative humidity of 90±2%
