4-Methyl-8-methylene-4,9-decadienal Encapsulation for Odor Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current perfumery technologies lack the use of 4-methyl-8-methylene-4,9-decadienal as a perfuming ingredient, which can impart aldehydic and floral notes, particularly evoking cardamom and lily of the valley, despite its potential in modifying odor properties.
Innovation Solution
4-methyl-8-methylene-4,9-decadienal, in the form of its stereoisomers or mixtures, is used as a perfuming ingredient in perfuming compositions and consumer products, blending harmoniously with floral or green-aldehyde types, and can be encapsulated to protect against premature decomposition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If 4-methyl-8-methylene-4,9-decadienal is used as a perfuming ingredient, then distinct aldehydic and floral notes are imparted, but the compound may be subject to premature decomposition
Solution Approach 1:
The patent applies preliminary action by encapsulating the 4-methyl-8-methylene-4,9-decadienal compound before its intended use in perfuming compositions. This encapsulation is performed in advance to prevent premature decomposition during storage and handling, ensuring the compound remains stable until it is released to provide its desired aldehydic and floral odor notes.
2Adaptability or versatility
If the compound is used to impart specific odor notes, then unique scent profile is achieved, but the dosage control becomes critical for harmonious blending
Solution Approach 1:
The patent applies parameter changes by carefully controlling the dosage concentration of 4-methyl-8-methylene-4,9-decadienal in perfuming compositions. By adjusting the amount of compound used, the inventors achieve harmonious blending with floral or green-aldehyde type compositions, allowing the compound to display either cardamom or lily of the valley notes depending on the specific dosage applied.
