Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for eco-friendly fabric softeners that utilize plant-based ingredients to provide transparency and performance comparable to traditional synthetic softeners, while maintaining softness and fragrance.
Innovation Solution
A fabric softener composition comprising a polyhydric alcohol (e.g., glycerin), a nonionic cellulose ether (e.g., hydroxyethyl cellulose), and a plant-based softening agent such as isopropyl palmitate or cationic wheat protein, with a pH maintained by organic acids like lactic acid, to achieve clarity and softening efficacy.

Engineering Contradiction Analysis
1Object-affected harmful factors
If plant-based ingredients are used in fabric softeners, then eco-friendliness is improved, but transparency and performance comparable to synthetic products deteriorate
Solution Approach 1:
The patent applies composite materials by combining multiple plant-based ingredients (polyhydric alcohol, nonionic cellulose ether, plasticizer, and cationic surfactant) to create a formulation that achieves both transparency and softening performance. This composite approach allows the synergistic interaction of different plant-derived components to overcome the limitations of individual plant-based ingredients.
Solution Approach 2:
The patent utilizes parameter changes by carefully controlling the pH of the formulation within a specific range (2-4) using organic acids. This pH adjustment optimizes the performance and transparency of the plant-based softener, demonstrating how modifying chemical parameters can enhance both eco-friendliness and functional performance.
2Stability of the object's composition
If plant-based softening agents are used, then sustainability is improved, but softening ability and appearance quality worsen
Solution Approach 1:
The patent applies local quality by assigning specific functions to different components within the formulation. The polyhydric alcohol and nonionic cellulose ether provide thickening and stabilization, the plasticizer contributes to transparency and softness, and the cationic surfactant delivers the primary softening action. This functional differentiation allows each component to optimize its local contribution to overall performance.
Solution Approach 2:
The patent employs parameter changes by adjusting the pH to a specific range (2-4) and controlling the concentration of each ingredient to achieve both sustainable plant-based composition and high-quality appearance and softening performance.
3Reliability
If conventional synthetic ingredients are used, then performance is improved, but environmental sustainability worsens
Solution Approach 1:
The patent applies parameter changes by adjusting the pH of the plant-based formulation to match the optimal performance range of conventional softeners. This pH optimization ensures that plant-based ingredients can deliver comparable softening performance while maintaining environmental sustainability.
Solution Approach 2:
The patent uses composite materials by combining multiple plant-based components to replicate the complex functionality of synthetic ingredients. This composite plant-based system achieves performance parity with conventional softeners while eliminating synthetic chemicals and improving environmental sustainability.
