Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current malodour counteracting methods fail to effectively neutralize a wide variety of malodours through chemical reactions without compromising sensorial properties, and many compounds used have unpleasant odours, making them unsuitable for household and cosmetic products.
Innovation Solution
A composition comprising hexanal, 3,7-dimethylocta-2,6-dienal, and 2,6-dimethyl-5-heptenal, in specific weight ratios, that neutralizes malodours by chemical reaction in both gaseous and liquid phases, maintaining pleasant sensorial properties and being suitable for use in articles and products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If compounds with high malodour neutralization capacity are used, then malodour elimination is improved, but the compounds themselves have unpleasant odours that compromise their use in consumer products
Solution Approach 1:
The patent combines three different aldehyde compounds (hexanal, 3,7-dimethylocta-2,6-dienal, and 2,6-dimethyl-5-heptenal) in specific ratios to create a composite composition. This composite approach allows the mixture to neutralize a broad spectrum of malodours through complementary chemical reactions while the combined sensorial profile remains pleasant, overcoming the limitation of individual compounds having unpleasant odours.
Solution Approach 2:
The patent optimizes the concentration parameters of each aldehyde compound within specific ranges (hexanal: 0.1-4%, 3,7-dimethylocta-2,6-dienal: 5-25%, 2,6-dimethyl-5-heptenal: 1-8%) to achieve the desired balance between malodour neutralization efficiency and pleasant sensorial properties. By carefully controlling these compositional parameters, the invention resolves the contradiction between effectiveness and acceptability.
2Device complexity
If a single compound is used to neutralize malodours, then the composition is simple, but it cannot neutralize all types of functional groups in malodour molecules
Solution Approach 1:
The invention uses a composite of three aldehyde compounds, each capable of reacting with different functional groups in malodour molecules (amines, thiols, sulphides, acids, aldehydes, and esters). This composite structure provides broad-spectrum neutralization capability while maintaining relative compositional simplicity with only three key ingredients in optimized ratios.
Solution Approach 2:
The aldehyde group functional present in all three compounds provides a universal mechanism for neutralizing various malodour functional groups through chemical reactions. Each compound in the composition contributes to multiple neutralization pathways, giving the composition multi-functional capability to handle diverse malodour types.
