Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fragrance compositions struggle to maintain stability and uniform evaporation rates while incorporating high levels of water and fragrance ingredients without surfactants, often leading to phase separation and aesthetic issues.
Innovation Solution
A composition comprising isopropylidene glycerol and water, with a maximum water content determined by Equation 1 (W(%)=(63±30)exp((−0.38±0.025)(ClogP)), ensuring stability and homogeneous distribution of fragrance ingredients, even at high water levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high levels of water and fragrance ingredients are incorporated without surfactants, then the composition achieves renewable feedstock usage and reduced solvent content, but phase separation occurs leading to aesthetic issues and instability
Solution Approach 1:
The patent introduces isopropylidene glycerol as an intermediary substance that mediates between water and fragrance ingredients. This solvent acts as a bridge, enabling miscibility between polar water molecules and non-polar fragrance compounds without requiring surfactants. The isopropylidene glycerol molecules interact with both water and fragrance ingredients through their dual polarity characteristics, preventing phase separation while maintaining composition stability.
Solution Approach 2:
The patent changes the chemical parameter of the solvent system by replacing conventional petrochemical solvents with isopropylidene glycerol, a renewable feedstock derivative. This parameter change in solvent chemistry enables the system to achieve both high water content (reducing VOCs) and fragrance solubility without phase separation, resolving the contradiction between environmental sustainability and composition stability.
2Productivity
If conventional petrochemical solvents are used, then uniform evaporation rate is achieved, but renewable feedstock usage and sustainability are compromised
Solution Approach 1:
The patent changes the origin parameter of the solvent from non-renewable petrochemical sources to renewable feedstocks through the use of isopropylidene glycerol. This renewable solvent maintains the necessary evaporation characteristics while improving the sustainability profile of the composition, allowing uniform fragrance release without compromising environmental credentials.
Solution Approach 2:
The patent adopts a renewable, biodegradable solvent (isopropylidene glycerol) that can be sustainably produced and replaced, replacing persistent petrochemical solvents. This approach prioritizes renewable resources that can be continuously replenished, aligning with sustainability goals while maintaining functional performance.
3Stability of the object's composition
If surfactants are added to maintain stability with high water content, then composition homogeneity is improved, but the complexity and potential harmful factors increase
Solution Approach 1:
The patent extracts and eliminates surfactants from the composition by using isopropylidene glycerol as an alternative solvent system. This removal of harmful surfactant components is achieved by substituting the need for surface-active agents with a renewable glycerol derivative that provides solubility and stability through different chemical mechanisms, thereby reducing harmful factors while maintaining homogeneity.
