Bottom-Heavy Fragrance Composition with Volatility Modulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fragrance compositions with high levels of low and moderate-volatility fragrance materials often result in a harsh perception, especially when these materials are natural and overdosed.
Innovation Solution
A fragrance composition with a bottom-heavy construction, featuring a fragrance component comprising at least one low volatile fragrance material, one moderate volatile fragrance material, and one high volatile fragrance material, along with a substantially non-odorous fragrance modulator, which allows for overdosing of low and moderate volatility materials without harshness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If high levels of low and moderate-volatility fragrance materials are used, then the fragrance profile is dominated by these materials, but the composition is perceived as harsh and unpleasant
Solution Approach 1:
The patent introduces a specifically formulated blend of high-volatility fragrance materials acting as an intermediary component that mediates between the low/moderate-volatility materials and the user's perception. This intermediary blend includes citrus notes, aquatic notes, and other light fragrance materials that soften the harsh perception while allowing the bottom-heavy construction to maintain its dominant character profile.
Solution Approach 2:
The patent applies parameter changes by adjusting the volatility distribution parameters of the fragrance composition. Specifically, it maintains low-volatility materials at greater than 30 wt% of the fragrance component while introducing high-volatility materials at controlled levels (0.1-30 wt%) to modify the evaporation profile and perception characteristics, thereby changing the temporal release pattern of the fragrance.
2Quantity of substance
If low-volatility fragrance materials are overdosed, then the bottom-heavy fragrance profile is achieved, but the composition becomes harsh to professional evaluators
Solution Approach 1:
The patent segments the fragrance composition into distinct volatility-based layers: a bottom layer of low-volatility materials (>30 wt% of fragrance component), a middle layer of moderate-volatility materials, and a top layer of high-volatility materials (0.1-30 wt%). This segmentation allows each layer to perform its specific function while maintaining overall harmony and acceptability to professional evaluators.
Solution Approach 2:
The patent creates a composite fragrance material system combining low-volatility base notes with high-volatility top notes in a unified composition. This composite approach integrates materials with different volatility characteristics to achieve a balanced profile that maintains the desired bottom-heavy character while ensuring professional acceptability through the contributing high-volatility components.

AI summary
According to various embodiments, a composition includes a fragrance component present in an amount of from about 0.04 wt % to about 30 wt %, relative to the total weight of the composition. The fragrance component includes at least one low volatile fragrance material present in an amount greater than 30 wt %, relative to the total weight of the fragrance component. This can be defined as a bottom-heavy fragrance. The fragrance component further includes at least one moderate volatile fragrance material present in an amount of from about 30 wt % to about 70 wt %, relative to the total weight of the fragrance component. The fragrance component further includes at least one high volatile fragrance material present in an amount of from about 0.1 wt % to about 30 wt % relative to the total weight of the fragrance component.
