Perfuming Composition Using Contrasting Accords to Prevent Olfactory Habituation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The perfume industry faces challenges in maintaining fragrance intensity and longevity over time due to perfume habituation and adaptation, where consumers experience a decrease in perceived scent intensity as they become accustomed to the fragrance.
Innovation Solution
A perfume composition comprising at least two contrasting perfume accords with specific volatility ranges and weight ratios, where each accord is designed to be perceived at different times, providing a sequential olfactory experience that enhances and prolongs the fragrance perception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a single perfume accord is used, then the fragrance composition is simple, but the perceived intensity decreases over time due to habituation and adaptation
Solution Approach 1:
The perfume composition is segmented into multiple distinct perfume accords (first accord with first olfactive note, second accord with second olfactive note) that are perceived at different times. This segmentation prevents habituation by continuously presenting new olfactory stimuli, thereby maintaining perceived intensity and extending the duration of interesting fragrance perception.
Solution Approach 2:
The fragrance composition employs periodic action through the sequential perception of contrasting olfactive notes at different time points. The first olfactive note is perceived at a first time, the second olfactive note at a second time, creating a temporal rhythm that prevents adaptation and maintains consumer interest over extended periods.
2Reliability
If contrasting perfume accords are used to prevent habituation, then the perceived intensity and longevity are improved, but the composition complexity increases
Solution Approach 1:
Different regions of the fragrance experience (different time points) are assigned different olfactive qualities. The first perfume accord provides a first olfactive note at an initial time, while the second perfume accord provides a contrasting second olfactive note at a later time. This local differentiation in olfactive quality prevents habituation while maintaining overall composition coherence.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition significantly increases perceived fragrance intensity and longevity by alternating olfactory notes, reducing habituation and adaptation, and maintaining a noticeable scent over an extended period.
Implementation Method 1
a first perfume accord comprises perfuming compounds having a volatility ranging from 70,000 to 100 μg/l in air, wherein a second perfume accord comprises perfuming compounds having a volatility ranging from 99 to 50 μg/l in air
Data Source
AI summary
The present disclosure provides fragrance compositions having an olfactive profile that changes with time. The fragrance compositions include at least two contrasting perfume accords. The at least two contrasting perfume accords provide an olfactory modulating effect, such that the fragrance compositions deliver a desirable scent with increased perceived intensity and improved longevity of perception.
