Cyclopentanol Compounds for Complex Fragrance Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The fragrance industry faces challenges in predicting the sensory activities of chemical structures, making it difficult to identify desirable fragrance chemicals for creating new perfumes and personal care products, as small differences in chemical structures can result in significant variations in odor profiles.
Innovation Solution
The development of novel cyclopentanols represented by specific formulas, which can be used to enhance, improve, or modify fragrances in perfumes, colognes, and personal care products, offering powerful and complex fragrance effects such as fresh, citrusy, and green notes with woodiness and earthy undertones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If small differences in chemical structures are made, then odor profiles vary significantly, but it becomes difficult to predict sensory activities
Solution Approach 1:
The patent systematically varies specific structural parameters of cyclopentanol compounds (substituent types, positions, and configurations) to achieve desired odor profiles. By changing R1 and R2 groups in Formula I, R3 and R4 in Formula II, and R5 and R6 in Formula III, the invention creates predictable structure-odor relationships that resolve the unpredictability issue while maintaining versatile fragrance characteristics
2Adaptability or versatility
If novel chemical structures are developed to create new fragrances, then fragrance diversity is improved, but identification of desirable fragrance chemicals becomes more challenging
Solution Approach 1:
The patent divides the fragrance development process into systematic segments: (1) defining specific cyclopentanol core structures, (2) systematically varying substituent groups (R1-R6) according to defined formulas, (3) evaluating sensory properties of each variant. This segmented approach transforms the challenging task of identifying desirable fragrance chemicals into a structured process with predictable outcomes
3Reliability
If cyclopentanols with specific structures are used to enhance fragrance, then fragrance performance is improved, but complexity of chemical structure increases
Solution Approach 1:
The patent applies local quality by introducing specific substituents (R1-R6 groups) at particular positions on the cyclopentanol core structure. Each substituent location and type is carefully selected to provide specific fragrance characteristics (fresh, citrusy, green notes with woodiness and earthy undertones) while maintaining overall structural manageability through the defined formulaic framework
