Volatile Aldehyde Malodor Neutralization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current malodor control products are ineffective in quickly neutralizing a broad range of malodors, particularly amine-based and sulfur-based odors like fish and urine, and may overpower scents rather than genuinely neutralizing them.
Innovation Solution
A malodor control composition comprising a mixture of volatile aldehydes, such as 2-ethoxy benzylaldehyde and thiophene carboxaldehyde, in combination with an acid catalyst, which reacts with malodors to form thiol acetals and hemiacetals, effectively reducing their intensity without overpowering desired perfumes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional malodor control products are used, then they may mask odors with perfume, but they fail to effectively neutralize amine-based and sulfur-based malodors
Solution Approach 1:
The patent changes the chemical parameters of the composition by using specific volatile aldehydes (1% to 5% by weight) combined with a weak acid catalyst (pKa 4.0 to 6.0) to enable chemical neutralization rather than masking, effectively reducing amine and sulfur malodors without relying on overpowering perfumes
Solution Approach 2:
The patent creates a composite malodor control composition combining volatile aldehydes with a weak acid catalyst, where the synergistic interaction between these components enables effective neutralization of diverse malodors while maintaining pleasant scent characteristics
2Reliability
If conventional malodor products are applied, then they provide some odor control, but they require extended time to noticeably reduce malodors
Solution Approach 1:
The patent changes the reaction kinetics by incorporating a weak acid catalyst that accelerates the neutralization reaction between volatile aldehydes and malodorous compounds, reducing the time required to achieve noticeable malodor reduction
Solution Approach 2:
The composition is designed to act immediately upon contact with malodors, with the pre-formulated volatile aldehydes and acid catalyst ready to react, eliminating delays associated with product activation or gradual release mechanisms
3Adaptability or versatility
If a broad spectrum of malodors is targeted, then diverse malodor types must be addressed, but existing products cannot effectively handle both amine-based and sulfur-based odors
Solution Approach 1:
The patent creates a universal malodor control composition where volatile aldehydes react with both amine-based and sulfur-based malodors through different chemical mechanisms (Schiff base formation with amines, thiol acetal formation with sulfur compounds), enabling single-product effectiveness across diverse malodor types
Solution Approach 2:
The weak acid catalyst acts as an intermediary that facilitates the reaction between volatile aldehydes and various malodorous compounds, enhancing the neutralization mechanism for both amine and sulfur-based odors through catalytic action
