Cyclopropane Fragrance Composition for Diffusive Lasting Citrus Notes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of compounds that effectively impart a floral or citrus-like odor with high diffusibility, long-lasting quality, and stability for use in various cosmetic, pharmaceutical, and food products, with existing substances failing to meet these requirements.
Innovation Solution
A compound with a cyclopropane ring, specifically synthesized through methods involving allyl alcohol derivatives and cyclopropane formation, is used to create a flavor and/or fragrance composition that provides a strong floral or citrus-like odor, excellent diffusibility, and long-lasting characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional flavor and fragrance compounds are used, then basic odor functionality is provided, but high diffusibility, long-lasting quality, and stability are insufficient
Solution Approach 1:
The patent modifies the chemical structure by introducing a cyclopropane ring with specific substituents (aromatic group, hydroxyl group, and various alkyl groups) to change the physical and chemical parameters of the molecule. This structural modification results in improved diffusibility, odor quality, stability, and longevity simultaneously, resolving the contradiction between reliability and adaptability.
2Adaptability or versatility
If existing cyclopropane compounds are used, then some odor characteristics are achieved, but the combination of floral/citrus-like odor with high diffusibility and long-lasting quality is not satisfied
Solution Approach 1:
The patent creates a composite molecular structure combining a cyclopropane ring with aromatic groups, hydroxyl groups, and various alkyl substituents. This composite structure integrates multiple functional groups that work together to provide both the desired floral/citrus-like odor quality and the long-lasting characteristics, resolving the contradiction between odor quality and duration.
