Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hard surface cleaning compositions face a dilemma where adding perfume for fragrance compromises the shine and stability of the composition due to the need for increased surfactant levels for emulsification.
Innovation Solution
Incorporating polyalkylene glycol with a weight average molecular weight between 4,000 to 10,000 to stabilize perfume and enhance shine, allowing for higher perfume levels without compromising stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the level of perfume is increased to provide better fragrance, then the scent intensity is improved, but the composition stability deteriorates and more surfactant is required for emulsification
Solution Approach 1:
Polyalkylene glycol is introduced as an intermediary substance between perfume and water. It acts as a co-emulsifier that stabilizes the perfume emulsion, allowing higher perfume levels (0.1-5% by weight) without compromising composition stability. The polyalkylene glycol with molecular weight 2,000-12,000 specifically mediates the interaction between hydrophobic perfume molecules and aqueous environment.
2Stability of the object's composition
If the level of surfactant is increased to emulsify higher perfume levels, then the perfume emulsification is improved, but the shine of the cleaned surface deteriorates
Solution Approach 1:
The invention changes the chemical composition parameters by introducing polyalkylene glycol with specific molecular weight (2,000-12,000, preferably 4,000-10,000). This parameter change enables the system to maintain perfume emulsification at higher levels while avoiding the negative impact on surface shine that would result from increasing surfactant concentration.
3Quantity of substance
If the level of perfume is increased to provide better fragrance, then the scent intensity is improved, but the chemical stability of perfume raw materials deteriorates
Solution Approach 1:
Polyalkylene glycol serves as a protective intermediary that stabilizes perfume raw materials chemically. It prevents degradation of perfume components even at elevated concentrations (0.1-5% by weight), thereby maintaining both high scent intensity and chemical stability of the perfume formulation.
