Macrocyclic Ketone Composition for Low-Dose Malodor Counteraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing malodor counteracting (MOC) compositions are ineffective against powerful malodors found in body, residential, and pet environments due to the need for excessive amounts of masking compounds to achieve a noticeable effect, as the chemicals responsible for these odors are detectable at very low levels.
Innovation Solution
A compound of formula [specifically defined as 4,8-cyclododecadien-1-one and its stereoisomers, used in a mixture with varying (E,E)/(E,Z) ratios, is employed to effectively counteract malodors by releasing into the air or over the source, acting through mechanisms of odor suppression and/or masking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional MOC compositions are used to mask malodors, then some odor suppression effect is achieved, but excessive amounts of masking compounds are required to obtain a noticeable effect
Solution Approach 1:
The patent changes the chemical structure parameters of the masking compound by introducing a specific macrocyclic ketone structure with defined stereochemistry (E,E)/(E,Z) ratios. This structural parameter change enables the compound to achieve superior malodor counteracting effectiveness at lower concentrations compared to traditional masking compounds, directly resolving the contradiction between effectiveness and quantity required.
2Reliability
If excessive amounts of MOC compositions are applied to achieve acceptable malodor counteracting action, then malodor suppression improves, but the complexity and dosage requirements of the composition increase
Solution Approach 1:
The patent specifies precise stereochemical parameters ((E,E)/(E,Z) ratio between 20/80 and 99.5/0.5) of the macrocyclic ketone compound to optimize its malodor counteracting performance. This parameter optimization allows the compound to achieve high effectiveness at lower dosages, reducing composition complexity and dosage requirements while maintaining or improving malodor suppression capability.
