Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional polymer systems in fabric treatment compositions improve stability but compromise freshness, and existing formulations often result in instability and loss of benefits when multiple benefit agents are combined, such as silicones and fabric softeners, leading to reduced performance.
Innovation Solution
A composition featuring a polymeric mixture with a first polymer derived from saccharides and a second polymer, optimized with cationic, hydrophobic, and hydrophilic modifications, along with specific ratios and additives, to enhance stability and maintain the benefits of fabric softeners and perfumes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional polymer systems are used to improve stability, then stability is improved, but freshness is compromised
Solution Approach 1:
The patent combines a synthetic polymer with a polymer derived from saccharides to create a composite polymer system. This composite approach allows the formulation to achieve both stability (from the synthetic polymer) and freshness retention (from the saccharide-derived polymer), resolving the trade-off between these two properties that plagues traditional single-polymer systems.
Solution Approach 2:
The patent modifies the polymer system by changing its chemical composition parameters - specifically incorporating polymers derived from saccharides with specific structural characteristics. This parameter change in the polymer architecture enables the system to maintain stability while preserving freshness, overcoming the limitations of conventional polymer systems.
2Adaptability or versatility
If multiple benefit agents are combined in one treatment composition, then performance is enhanced, but instability and loss of benefits occur
Solution Approach 1:
The composite polymer system acts as a stabilizing matrix that can accommodate multiple benefit agents (fabric softeners, perfumes, silicones) while maintaining composition stability. The synergistic interaction between the synthetic and saccharide-derived polymers creates a compatible environment for multiple actives, preventing the instability that typically arises from combining multiple benefit agents.
3Adaptability or versatility
If fabric softener active is reduced to maintain perfume effectiveness, then perfume performance is improved, but feel benefit decreases
Solution Approach 1:
The composite polymer system enhances the efficiency of fabric softener active, allowing lower concentrations to achieve the same or better performance. This efficiency enhancement is attributed to the synergistic interaction between the two polymer types, which improves active hydration and promotes better diffusion and performance of the softener active at reduced levels.
