Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current perfumery compositions face challenges in achieving sufficient solubility, olfactory performance, and skin safety due to the use of solubilizing agents like vicinal diols and ethanol, which often result in greasy textures, irritation, and environmental concerns.
Innovation Solution
A perfume complex comprising 15-45% perfume, 15-50% isopentyldiol, and 15-30% C12-13 pareth-9, without water and ethanol, forming a stable, low-tack, and transparent composition suitable for various olfactory families, ensuring compatibility and prolonged olfactory perception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If vicinal diols or other solubilizing agents are used to ensure sufficient solubility of perfume in water, then solubility is improved, but the composition becomes greasy and tacky with skin irritation
Solution Approach 1:
The invention extracts and eliminates the harmful solubilizing agents (vicinal diols, ethanol, surfactants) from the composition while maintaining perfume solubility through an alternative water-free approach using a specific perfume-to-water ratio and co-solvents like isosorbide or solketal that do not cause irritation or greasy texture
Solution Approach 2:
The invention changes the fundamental parameter of water content from traditional aqueous formulations to a water-free or low-water composition, using controlled amounts of water (0-10%) combined with specific co-solvents to achieve solubility without the harmful effects of conventional solubilizing agents
2Stability of the object's composition
If ethanol is used as a solvent to achieve good olfactory performance and solubility, then perfume solubility and volatility are improved, but environmental harm and regulatory compliance issues arise
Solution Approach 1:
The invention converts the traditional role of ethanol as a solvent into a water-free or low-water formulation using environmentally benign co-solvents like isosorbide or solketal, which provide similar solubility and volatility benefits without VOC emissions, thereby transforming an harmful formulation approach into an environmentally friendly one
Solution Approach 2:
The invention changes the solvent composition parameter by replacing ethanol with water-free formulations using isosorbide or solketal as primary co-solvents, maintaining the necessary solubility and volatility characteristics while eliminating harmful VOC emissions
3Quantity of substance
If high perfume dosage is used to ensure olfactory performance, then scent intensity is improved, but solubility and stability become problematic
Solution Approach 1:
The invention introduces isosorbide or solketal as intermediary co-solvents that facilitate the solubility of high perfume dosages in water-free or low-water formulations, acting as a bridge between the perfume ingredients and the aqueous medium to maintain stability at elevated perfume concentrations
