Wet Wipe Cleansing Composition Balancing Soil Removal and Sensory Feel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Synthetic wet wipes with high cleansing composition loads suffer from reduced absorbent capacity and adhesive interactions, leading to smeared soils rather than effective removal, compromising cleaning performance while aiming for good sensory perception.
Innovation Solution
A cleansing composition comprising glucomannan, xanthan gum, and carrageenan, with a peak complex viscosity of 0.8 Pa·s to 7.0 Pa·s, is used in a wet wipe, enhancing adhesive interactions between the soil and the wipe without compromising sensory perception by using low glucomannan concentrations and synergy enhancing agents like xanthan gum.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the wet wipe is loaded with more cleansing composition to provide the same sensory perception as natural fiber wipes, then the sensory perception is improved, but the adhesive interactions between soil and substrate are reduced, causing soil to smear rather than be removed
Solution Approach 1:
The patent changes the rheological parameters of the cleansing composition by incorporating shear-thinning polymers (xanthan gum, guar gum, carbomer) that exhibit non-Newtonian fluid behavior. This allows the composition to have high viscosity at rest (providing sensory perception and adhesion) but low viscosity during wiping motion (enabling soil removal). The specific parameter changes include viscosity as a function of shear rate, yielding stress, and gel structure that maintain adhesive properties without compromising cleaning effectiveness
Solution Approach 2:
The patent uses composite material systems combining multiple polymers (xanthan gum, guar gum, carbomer) with surfactants and other cleansing agents. This composite approach creates a synergistic effect where the polymer network provides structural integrity and adhesion while the surfactant system enables soil detachment and emulsification, resolving the contradiction between maintaining sensory perception and achieving effective soil removal
2Ease of operation
If the wet wipe is loaded with more cleansing composition to improve sensory perception, then the sensory perception is improved, but the absorbent capacity of the wipe is reduced as more of the wipe structure is filled with liquid
Solution Approach 1:
The patent changes the physical state and rheological parameters of the cleansing composition by using shear-thinning polymers that form gel structures. These gels have high viscosity and yield stress at rest, providing sensory perception similar to natural fiber wipes, but exhibit shear-thinning behavior during use that allows the wipe to absorb additional liquid and maintain absorbent capacity. The key parameter changes involve viscosity-shear rate relationships and gel network formation that optimize both sensory and absorbent properties
