Alicyclic Alcohol Composition for Lasting Floral-Woody Diffusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a demand for alicyclic alcohols with complex scents including floral notes of muguet, jasmine, and rose, along with a soft woody note in a lasting scent, to enhance fragrance compositions and impart diffusibility to floral and woody notes.
Innovation Solution
Synthesis and blending of specific alicyclic alcohols, such as (4-isopropyl-2-methylcyclohexyl) methanol and (2-isopropyl-4-methylcyclohexyl) methanol, in compositions with a total content of 95 mass% or higher, and a mass ratio of 85/15 to 98/2, to create a fragrance composition with enhanced floral and woody notes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional alicyclic alcohols are used as fragrance ingredients, then basic floral scents are achieved, but complex scents with lasting properties and good diffusibility are not obtained
Solution Approach 1:
The patent combines multiple alicyclic alcohol compounds with specific chemical structures (Formulae 1-3) to create a composite fragrance composition. This composite approach integrates different molecular structures that individually contribute to floral notes, woody notes, and diffusibility, achieving a complex scent profile with lasting properties that single compounds cannot provide
Solution Approach 2:
The patent optimizes specific parameters including the content ratios of different alicyclic alcohols (Formulae 1-3), molecular structure characteristics (isopropyl, methyl, and hydroxymethyl groups), and physical properties to achieve the desired balance of lasting scent and diffusibility. By adjusting these parameters, the composition achieves both reliability in lasting properties and versatility in scent complexity
2Adaptability or versatility
If new fragrance compounds are developed to achieve complex scents, then novel fragrance profiles are obtained, but excellent lasting scent properties may be compromised
Solution Approach 1:
The patent creates a composite formulation combining multiple alicyclic alcohol compounds (Formulae 1-3) where each component contributes different aspects of the fragrance profile. This composite structure allows the novel fragrance profile to be achieved while the synergistic combination provides the lasting scent properties that individual novel compounds might lack
Solution Approach 2:
The patent assigns specific functional roles to different components within the composition: certain alicyclic alcohols provide floral notes, others provide woody notes, and the specific molecular structures contribute to either lasting properties or diffusibility. This local quality differentiation within the composite allows simultaneous achievement of novelty and durability
