Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Super absorbent polymers used in hygienic products like diapers face challenges in effectively inhibiting odor and bacteria growth, which degrade the afterfeel and generate additional odors over time, especially in pulpless or low-pulp products.
Innovation Solution
A composition of super absorbent polymer incorporating a base resin with a surface crosslink layer, an amino acetate-based chelating agent, and cysteine, which are added during specific steps of the polymerization process to enhance deodorization and odor masking capabilities without compromising absorption properties.

Engineering Contradiction Analysis
1Length of moving object
If super absorbent polymer is used in pulpless or low-pulp hygienic products, then thickness is reduced and hygiene is improved, but odor inhibition capability deteriorates
Solution Approach 1:
The patent combines super absorbent polymer with specific functional additives (metal salt, organic acid, polyphenol) to create a composite material that simultaneously provides absorption and odor inhibition capabilities, allowing thin-pulp products to maintain both thickness reduction benefits and odor control
Solution Approach 2:
The super absorbent polymer composition is designed to perform multiple functions: absorption, odor inhibition, and bacteria growth suppression, enabling a single material to address multiple requirements of thin-pulp hygienic products without compromising any individual function
