Non-Volatile Precursor Compounds for Long-Lasting Floral Odor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing perfumes and perfumed articles have limited longevity due to the high volatility of their fragrance components, resulting in a short-lasting odor perception, particularly for fresh green, floral, and fruity notes.
Innovation Solution
The use of specific compounds of formula (I), which are non-volatile and essentially odorless, that slowly generate α,β-unsaturated aldehydes or ketones and thiols over time, providing a long-lasting floral and fruity odor when applied to surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If volatile fragrance compounds are used to provide fresh green, floral, and fruity notes, then the desired odor character is achieved, but the duration of odor perception is limited
Solution Approach 1:
The patent applies preliminary action by incorporating non-volatile precursor compounds (sulfones, sulfonates, or sulfoxones) into the perfume composition before application. These precursors are deposited onto the skin in advance and then slowly convert into the desired volatile fragrance compounds over time, providing a long-lasting odor effect without the initial volatility problem
Solution Approach 2:
The patent uses non-volatile sulfur-containing compounds as intermediary substances that serve as precursors. These intermediaries are applied to the skin and gradually transform into the actual fragrance molecules through oxidation and hydrolysis reactions, mediating between the need for long-lasting presence and the need for volatile odor release
2Duration of action of moving object
If non-volatile compounds are used to extend odor duration, then the longevity is improved, but the compounds are essentially odorless without slow generation of fragrance
Solution Approach 1:
The patent applies self-service by designing precursor compounds that automatically transform into fragrance molecules through reactions with components naturally present on the skin (such as enzymes, moisture, or oxygen). The compounds self-generate the desired odor without requiring external triggers or additional ingredients, providing both longevity and fragrance character
Solution Approach 2:
The patent utilizes parameter changes by controlling the chemical transformation of precursor compounds through changes in molecular structure, oxidation state, and hydrolysis rate. The precursors are designed with specific functional groups that undergo controlled chemical changes over time, transitioning from non-volatile, odorless states to volatile, fragrant states, thereby achieving both long duration and desired odor character
