Perfuming Composition for Long-Lasting Strawberry Odor Solubility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing perfuming compositions struggle to maintain long-lasting strawberry odor due to the volatility of oct-2-ene-4-one, and 2-(alkylsulfonyl)octan-4-one compounds are difficult to dissolve in fragrance oils at high concentrations without dilution, limiting their olfactive impact.
Innovation Solution
A perfuming composition comprising a 2-(alkylsulfonyl)octan-4-one compound dissolved in an oil phase with perfumery raw materials at a concentration of at least 5 wt.%, using solvents like gamma-nonalactone and Hedione® to ensure full solubility at room temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If 2-(alkylsulfonyl)octan-4-one compounds are used to provide long-lasting strawberry odor, then the duration of action is improved, but the solubility in fragrance oils deteriorates
Solution Approach 1:
The patent changes the chemical parameters of the solvent system by selecting specific solvents (gamma-nonalactone, Hedione®, dipropylene glycol, isopropyl myristate) with appropriate solubility characteristics to dissolve 2-(alkylsulfonyl)octan-4-one compounds at high concentrations (≥5 wt.%) at room temperature, resolving the solubility issue while maintaining the long-lasting odor effect
Solution Approach 2:
The patent creates a composite perfuming composition by combining 2-(alkylsulfonyl)octan-4-one compounds with a multi-component solvent system, where the synergistic interaction between different solvents enables high-concentration dissolution at room temperature, thus achieving both long duration and good solubility
2Ease of operation
If 2-(alkylsulfonyl)octan-4-one compounds are dissolved in solvent before addition, then the ease of operation is improved, but the concentration in final product deteriorates
Solution Approach 1:
The patent uses a pre-formulated solvent system as an intermediary vehicle that can dissolve 2-(alkylsulfonyl)octan-4-one compounds at high concentrations (≥5 wt.%) at room temperature. This intermediary solution enables easy mixing and handling while maintaining high active compound concentration in the final perfuming composition, avoiding the need for heating or extensive stirring
3Illumination intensity
If high concentration of 2-(alkylsulfonyl)octan-4-one is used to ensure olfactive impact, then the intensity is improved, but the difficulty of dissolution deteriorates
Solution Approach 1:
The patent changes the physical parameters of the dissolution process by selecting solvents with appropriate boiling points and solubility characteristics that enable dissolution of high concentrations (≥5 wt.%) of 2-(alkylsulfonyl)octan-4-one at room temperature, eliminating the need for heating or intensive mechanical stirring while maintaining high olfactive impact
