Malodor counteracting compositions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing malodor counteractants are highly volatile and unable to effectively neutralize odors for an extended period, failing to provide long-lasting odor control.
Innovation Solution
Development of malodor counteracting compositions that include a malodor counteractant with a backbone and reactive end groups, combined with a stabilizer to prevent self-polymerization, resulting in a stable and effective solution for neutralizing thiol- or amine-based malodors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If highly volatile malodor counteractants are used, then immediate odor neutralization is achieved, but the duration of action is short
Solution Approach 1:
The malodor counteractant is segmented into two functional parts: a volatile head group (α,β-unsaturated carbonyl) that provides immediate odor neutralization, and a non-volatile backbone (polymer, oligomer, or surfactant) that provides prolonged duration. This segmentation allows each component to fulfill its specific function - the volatile head reacts quickly with malodors while the non-volatile backbone remains on the surface extended period
Solution Approach 2:
The invention uses composite material structure by combining volatile and non-volatile components into a single malodor counteractant molecule. The composite structure integrates the rapid-action properties of volatile compounds with the long-lasting properties of non-volatile substances, achieving both immediate effectiveness and extended duration of odor control
2Stability of the object's composition
If stabilizers are added to prevent self-polymerization, then stability is improved, but composition complexity increases
Solution Approach 1:
A stabilizer is introduced as an intermediary substance that prevents self-polymerization of the α,β-unsaturated carbonyl groups. The stabilizer acts as a mediator that interferes with the polymerization reaction between counteractant molecules, thereby maintaining composition stability and preventing degradation over time
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

AI summary
A malodor counteracting composition contains a malodor counteractant that is capable of neutralizing a malodor and a stabilizer that is capable of decreasing or preventing self-polymerization of the malodor counteractant. The malodor counteractant has a backbone and one or more reactive end groups that are covalently attached to the backbone, the backbone has a molecular weight of 100 to 50,000 Daltons, and the one or more reactive end groups each have an α,β-unsaturated carbonyl group. Also disclosed are consumer, industrial or textile products containing the malodor counteracting composition and methods of neutralizing malodor using the composition.
