Ternary Cyclodextrin Mixture for Demographic-Specific Odor Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current deodorant compositions are inadequate in effectively addressing age and gender-specific body odors, as they fail to account for the varying chemical compositions of sweat across different life stages and genders, leading to inconsistent odor control.
Innovation Solution
A ternary mixture of α-, β-, and γ-cyclodextrins in specific weight ratios (2:1:1, 1:2:1, 1:1:2, and 1.5:0.5) is used to create an odour-absorbing composition that effectively controls and masks body odors in teenagers, adult men, women, and older individuals by optimizing the prevalence of each cyclodextrin type based on the user's category.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single type of cyclodextrin is used, then the composition is simple and easy to manufacture, but it can only absorb a limited spectrum of body odors
Solution Approach 1:
The patent combines three different types of cyclodextrins (α, β, and γ) into a single deodorant composition. Each cyclodextrin type has different cavity sizes that can accommodate various sized odor molecules, thereby expanding the overall odor absorption spectrum beyond what any single cyclodextrin type could achieve alone.
Solution Approach 2:
The invention uses a composite material system consisting of multiple cyclodextrin polymers with different structural properties. The specific ratios of α-cyclodextrin (0.1-2.0%), β-cyclodextrin (0.1-1.0%), and γ-cyclodextrin (0.1-0.5%) create a composite that leverages the unique absorption characteristics of each component to handle diverse odor molecules.
2Object-affected harmful factors
If antimicrobial agents and fragrances are used to control malodours, then odor masking is achieved, but the composition may cause skin irritation and does not address the root cause
Solution Approach 1:
Instead of using antimicrobial agents to kill bacteria or fragrances to mask odors, the patent employs cyclodextrins to bind with odor molecules through inclusion complexation. This converts the harmful odor molecules into benign complexes that can be easily removed, eliminating the need for potentially irritating chemicals while addressing the symptom without harming the skin.
Solution Approach 2:
Cyclodextrins act as intermediary molecules that facilitate the removal of odor molecules from the skin surface. The cyclodextrin cavity structure serves as a mediator that captures and sequesters odor molecules, preventing them from interacting with the skin and being perceived as unpleasant odors, without requiring direct contact between the skin and harsh antimicrobial or fragrance chemicals.
3Adaptability or versatility
If activated charcoal and zeolites are used as odour absorbers, then some odor control is achieved, but they lack specificity for different age and gender-related body odors
Solution Approach 1:
The patent applies the principle of local quality by assigning different cyclodextrin types to target specific odor profiles associated with different demographic groups. The composition can be tailored with specific ratios of α, β, and γ-cyclodextrins to address the unique odor characteristics of teenagers, adult men, adult women, and elderly individuals, providing localized optimization for each group's specific needs.
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 specific cyclodextrin ratios significantly enhance the composition's ability to absorb and mask body odors, as demonstrated by sniff tests showing improved odor control across different age and gender groups, with the best results achieved for teenagers, women, men, and elderly individuals.
Implementation Method 1
The use of cyclodextrins to absorb odours including body odours such as perspiration malodours, is well known. Solid and liquid deodorant composition comprising cyclodextrins are disclosed
