Cyclohexane Derivatives for Odor Note Modification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The flavor and fragrance industry lacks compounds that can enhance, modify, or improve odor notes, limiting the creation of new fragrances for perfumes, personal care products, and household items.
Innovation Solution
The use of specific organic compounds of formula (I), where R1 signifies -CH3, CH2CH3, or -CH2CH2CH3, and R2, R3, and R4 have specific definitions, as flavor and fragrance materials, either alone or in combination with other known odorant molecules, in formulations that include diluents and auxiliary agents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional flavor and fragrance compounds are used, then existing fragrance formulations can be maintained, but the ability to enhance, modify, or improve odor notes is limited
Solution Approach 1:
The patent applies parameter changes by systematically varying the molecular structure of fragrance compounds through different substituent groups (R1-R6) at specific positions on the cyclohexane ring. By changing parameters such as methyl, ethyl, propyl groups at position 2 and hydroxy, methoxy, acetoxy groups at positions 3 and 4, the invention creates a series of derivatives with modified odor characteristics, thereby enhancing adaptability while maintaining a manageable quantity of compounds.
2Adaptability or versatility
If new organic compounds are developed to improve fragrance capabilities, then odor note enhancement is achieved, but formulation complexity increases
Solution Approach 1:
The patent applies universality by designing a core cyclohexane structure (1-acetyl-2-substituted-3,4-disubstituted-cyclohexane) that serves as a universal platform for multiple fragrance applications. This multi-functional core structure can accommodate various substituent combinations to achieve different odor notes, reducing formulation complexity while maintaining enhancement capabilities across multiple product types.
Solution Approach 2:
The patent applies local quality by introducing specific functional groups at particular positions on the cyclohexane ring to achieve localized odor modifications. For example, placing hydroxy or acetoxy groups at positions 3 and 4 while maintaining a substituent at position 2 creates specific odor characteristics without requiring complete restructuring of the entire molecule, thereby managing complexity while achieving targeted odor enhancement.
3Reliability
If specific organic compounds of formula (I) are used to enhance odor notes, then fragrance improvement is achieved, but the concentration range for optimal performance must be precisely controlled
Solution Approach 1:
The patent applies parameter changes by establishing an optimal concentration range (0.0001-10 wt-%) for the fragrance compounds in formulations. This parameter optimization ensures reliable fragrance improvement while providing a broad enough range to accommodate manufacturing variations without requiring extreme precision, thus balancing effectiveness with manufacturing feasibility.
