Silver Zeolite Deodorant Composition for Yellowing Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing absorbent articles using silver zeolite for deodorant performance face challenges in improving deodorant efficacy and preventing yellowing over time.
Innovation Solution
Incorporating a sulfur compound with silver zeolite in a deodorant composition for absorbent articles, either with or without a water-absorbent resin, enhances deodorant performance and suppresses yellowing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If silver zeolite is used as a deodorant component, then deodorant performance is improved, but the deodorant composition turns yellow over time
Solution Approach 1:
A sulfur compound is introduced as an intermediary substance that interacts with silver zeolite to prevent yellowing. The sulfur compound acts as a mediator that maintains the stability of silver zeolite, preventing its oxidation and subsequent yellowing while preserving its deodorant functionality.
Solution Approach 2:
The invention creates a composite deodorant composition by combining silver zeolite with a sulfur compound. This composite material leverages the deodorant properties of silver zeolite while the sulfur compound provides stabilization, preventing yellowing through their synergistic interaction.
2Reliability
If silver zeolite is used to suppress odor generation, then deodorant efficacy is enhanced, but yellowing occurs reducing commercial value
Solution Approach 1:
The sulfur compound serves as a protective intermediary that extends the color stability duration of silver zeolite. By introducing this intermediary substance, the composition maintains its original color for longer periods while retaining enhanced deodorant efficacy.
Solution Approach 2:
The invention changes the chemical environment parameters by adding a sulfur compound, which alters the oxidation resistance of silver zeolite. This parameter change prevents the yellowing reaction, thereby extending the duration of color stability without compromising deodorant performance.
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 combination of silver zeolite and sulfur compound improves deodorant performance and prevents yellowing for up to 14 days, reducing ammonia generation to low levels.
Implementation Method 1
silver zeolite and a sulfur compound are jointly used, deodorant performance is improved
Implementation Method 2
when silver zeolite and a sulfur compound are jointly used, it is possible to suppress yellowing of the deodorant composition over time
