Volatile Aldehyde Mixture for Rapid 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 sulfur-based odors like garlic, and often require time before noticeable reduction, leading to consumer doubt in their efficacy.
Innovation Solution
A malodor control composition comprising a mixture of two or more volatile aldehydes, such as 2-ethoxy benzylaldehyde, 2-isopropyl-5-methyl-2-hexenal, and cinnamic aldehyde, which effectively neutralizes amine and sulfur-based malodors by chemical reaction, achieving at least 20% neutralization within specific time frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional malodor control products are used, then they may mask odors, 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 a mixture of volatile aldehydes with specific vapor pressure ranges (0.001-0.100 torr at 25°C) and specific chemical structures. This parameter optimization enables effective neutralization of both amine-based and sulfur-based malodors, resolving the contradiction between reliability on specific malodor types and versatility across broad ranges.
Solution Approach 2:
The invention uses a composite formulation combining multiple volatile aldehydes (such as 2-ethoxy benzylaldehyde, 2-isopropyl-5-methyl-2-hexenal, cinnamic aldehyde, and others) in specific combinations. This composite approach allows the composition to effectively neutralize diverse malodor types including amine-based, sulfur-based, and other difficult-to-combat odors, achieving both reliability and versatility.
2Reliability
If conventional malodor control products are applied, then they may eventually reduce malodors, but the time required creates consumer doubt as to efficacy
Solution Approach 1:
The volatile aldehydes in the composition are pre-positioned in a ready-to-react state with vapor pressures optimized for immediate volatilization upon application. This preliminary preparation enables the composition to begin neutralizing malodors almost instantly, achieving noticeable reduction within seconds to minutes rather than requiring extended time periods, thereby eliminating consumer doubt about efficacy.
Solution Approach 2:
By optimizing the vapor pressure parameters of the selected aldehydes to fall within the specific range of 0.001-0.100 torr at 25°C, the invention ensures rapid volatilization and immediate availability of active ingredients for malodor neutralization. This parameter control enables fast action while maintaining sustained effectiveness.
3Ease of operation
If strong perfumes are added to mask malodors, then odor coverage may improve, but the perfume overwhelms and masks the effectiveness of malodor neutralization
Solution Approach 1:
The invention converts the potential harm of strong perfumes into a benefit by using the volatile aldehydes themselves as the primary active ingredients that provide both malodor neutralization and pleasant fragrance. The aldehydes react with malodorous compounds to neutralize them while simultaneously providing a fresh, pleasant scent, eliminating the need for separate strong perfumes that would mask rather than neutralize.
Solution Approach 2:
The volatile aldehydes perform multiple functions simultaneously: they neutralize malodors through chemical reaction, provide pleasant fragrance, and create a fresh scent profile. This multi-functionality eliminates the need for separate perfume components, ensuring that odor coverage is achieved through genuine neutralization rather than masking.
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 rapidly reduces amine-based malodors by 20% in under 40 seconds and sulfur-based malodors by 20% in 30 minutes, providing a genuine neutralization rather than masking, as demonstrated by gas chromatographic analysis and sensory tests.
