Fragrance Composition Hexanal Malodor Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fragrance compositions fail to effectively reduce discomfort caused by hexanal-based malodors such as body, scalp, and bathroom odors without masking them with strong scents, limiting the range of scent tones and providing insufficient deodorizing effects.
Innovation Solution
A fragrance composition incorporating specific compounds like 3-(menthoxy)propane-1,2-diol, ethyl 3-mercapto-2-methylbutyrate, and essential oils like bergamot and cedar leaf oil, combined with additional fragrance components, to effectively reduce hexanal odor intensity across various malodors.

Engineering Contradiction Analysis
1Object-affected harmful factors
If strong-scent fragrance components (spearmint oil, peppermint oil, menthol, menthone, isomenthone, carvone) are used to mask malodor, then the malodor is covered, but the range of product scents is limited and the deodorizing effect is not sensually sufficient
Solution Approach 1:
The patent changes the chemical parameters of the fragrance composition by introducing specific compounds (3-(menthoxy)propane-1,2-diol, ethyl 3-mercapto-2-methylbutyrate, dimethyl-2-(1-phenylethyl)cyclopropylmethanol, 5-cyclohexadecenone, ethyl 2,2,6-trimethylcyclohexane-1-carboxylate) that interact with hexanal at the molecular level. This shifts the mechanism from simple masking to chemical modification, expanding scent options beyond traditional strong fragrances.
Solution Approach 2:
The patent creates a composite fragrance system combining multiple specific compounds working synergistically. This composite approach allows diverse scent profiles (floral, fruity, woody, fresh) to be achieved while maintaining effective deodorizing performance, resolving the limitation of single-tone strong scents.
2Object-affected harmful factors
If strong-scent fragrance components are used to mask malodor, then the malodor is covered, but the deodorizing effect is not sensually sufficient
Solution Approach 1:
The patent introduces specific fragrance compounds as intermediaries that chemically interact with hexanal molecules. These compounds (particularly 3-(menthoxy)propane-1,2-diol and ethyl 3-mercapto-2-methylbutyrate) act as mediators that bind to or react with hexanal, transforming the malodor mechanism from surface-level masking to deep-level chemical intervention, ensuring reliable and sensual deodorizing效果.
Solution Approach 2:
The patent modifies the chemical parameters of the fragrance system by using compounds with specific molecular structures and properties that enhance interaction with hexanal. This parameter optimization ensures consistent and reliable deodorizing performance across different application conditions.
3Adaptability or versatility
If traditional fragrance components are used, then the scent tone is limited to peppermint and herbs, but diverse scent tones are needed for different applications
Solution Approach 1:
The patent makes the fragrance composition universally applicable across multiple scent categories (floral, fruity, woody, fresh) while maintaining effective hexanal control. The specific compounds introduced can work across different fragrance families, allowing one composition to serve multiple application needs without sacrificing malodor control performance.
Solution Approach 2:
The patent creates a composite fragrance system that integrates multiple scent-profile compounds with proven hexanal-interaction capabilities. This allows formulation of diverse scent tones while maintaining reliable deodorizing function, as the composite structure ensures at least one active component will effectively control malodor regardless of the dominant scent profile.
