Multicyclic Compounds for Long-Lasting Fragrance via Microcapsule Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Perfumes with high volatility result in short-lasting fragrances, particularly for fruity and floral notes, which consumers desire to be long-lasting and substantive on surfaces like skin, hair, and hard surfaces.
Innovation Solution
Multicyclic compounds derived from cyclopentanone-based perfumery ingredients that slowly generate non-volatile, odorless compounds over time, providing a long-lasting fruity and floral scent when exposed to environmental conditions, such as humidity or light, leading to a prolonged fragrance release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If volatile fragrance compounds are used to provide fresh fruity and floral notes, then the odor is pleasant and appealing to consumers, but the fragrance evaporates rapidly and does not last long on surfaces
Solution Approach 1:
The patent applies preliminary action by incorporating fragrance compounds into microcapsules before application to the surface. The microcapsules are pre-formed and contain the volatile fragrance compounds, which are released gradually as the microcapsules break or degrade over time, providing sustained fragrance delivery rather than immediate evaporation.
Solution Approach 2:
The patent uses microcapsules with flexible shell structures to encapsulate volatile fragrance compounds. These thin film shells protect the volatile compounds from rapid evaporation while allowing controlled release over time, effectively extending the duration of fragrance perception without sacrificing the pleasant fruity and floral notes.
2Duration of action of moving object
If non-volatile compounds are used to extend fragrance duration, then the odor lasts longer on surfaces, but the fragrance intensity and freshness are reduced
Solution Approach 1:
The patent segments the fragrance delivery system into microcapsules containing volatile fragrance compounds. This segmentation allows a small amount of highly concentrated volatile fragrance to be distributed across many microcapsules, which are applied to the surface. As microcapsules break individually over time, they release their fragrance content, providing both extended duration and maintained intensity through cumulative release.
Solution Approach 2:
The patent changes the physical state and release parameters of fragrance compounds by encapsulating them in microcapsules. The microcapsule structure transforms the immediate evaporation behavior into a controlled, time-dependent release pattern, allowing the fragrance to maintain effective concentration levels over an extended period while still delivering the volatile compounds that provide freshness and appeal.
3Productivity
If traditional perfume compositions are applied to surfaces, then the initial odor perception is strong, but the fragrance fades quickly due to rapid evaporation of top notes
Solution Approach 1:
The patent implements periodic action through the staged release of fragrance compounds from microcapsules. As microcapsules break or degrade over time, they release their contents in periodic pulses, creating a sustained fragrance presence. This periodic release mechanism ensures that fresh fragrance notes continue to be delivered to the environment over an extended period, counteracting the rapid fading of traditional perfume top notes.
