Absorbent Article Odor Control Without Solvent Carriers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing odor control compositions for feminine hygiene pads require solvent carriers, which increase manufacturing complexity and risk of fire, and can negatively impact visual signals and inks on packaging materials.
Innovation Solution
An odor control composition comprising methylated beta-cyclodextrin, a cyclodextrin-compatible surfactant, a preservative, and a fragrance, applied in an aqueous-based formulation without a solvent carrier, ensuring stability and effective odor control while maintaining visual signals and ink integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If solvent carrier is used in odor control composition, then the composition can be applied easily and dries well on feminine hygiene article, but manufacturing complexity increases and fire risk increases
Solution Approach 1:
The patent removes the solvent carrier from the odor control composition, extracting the problematic element that causes manufacturing complexity and fire risk while retaining the essential odor control function through alternative application methods
Solution Approach 2:
The patent changes the physical and chemical parameters of the composition by eliminating the solvent phase, transforming it from a solvent-based formulation to a solvent-free or water-based formulation that maintains applicability without requiring evaporation and abatement systems
2Ease of operation
If solvent carrier is used in odor control composition, then the composition can be applied easily, but fire risk increases
Solution Approach 1:
The patent eliminates the flammable solvent carrier, converting a harmful element (fire risk) into a benefit (safer manufacturing and handling) while maintaining or improving the composition's effectiveness through alternative formulation approaches
3Ease of operation
If solvent carrier is used in odor control composition, then the composition can be applied easily, but visual signals and inks on packaging materials are negatively impacted
Solution Approach 1:
The patent removes the solvent carrier that causes degradation of visual signals and inks, extracting the harmful element while preserving the composition's ability to control odor through alternative delivery mechanisms
