Malodor Reduction in Air Care via Lauryl Methacrylate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air care products often fail to completely eliminate malodors, relying on masking scented perfumes that lose potency over time, leaving residual malodor issues in various environments such as kitchens, bathrooms, and offices.
Innovation Solution
The use of a composition combining lauryl methacrylate as a malodor reducing component with freshening fragrance components, including volatile aldehydes, esters, and alcohols, which chemically neutralize and mask malodors, providing sustained odor reduction and freshness in air care products like reed diffusers, scented candles, and sprays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If scented perfumes are used to mask malodors, then the freshening effect is improved, but the malodor reduction effectiveness deteriorates over time as the perfume potency wears off
Solution Approach 1:
The invention segments the air care function into two distinct components: a malodor active ingredient (such as zinc ricinoleate, zinc stearate, or other metal soaps) for eliminating malodors, and a separate scented perfume for providing freshening effect. This segmentation allows each component to perform its specific function independently and continuously, rather than relying on a single masking perfume that depletes over time.
Solution Approach 2:
The composition combines multiple functional ingredients into a single air care product: the malodor active ingredient provides continuous malodor reduction through chemical neutralization, while the scented perfume simultaneously provides freshening and masking effects. This multi-functional composition ensures both malodor control and fresh scent are maintained throughout the product's lifespan.
2Reliability
If malodor active ingredients are used to reduce malodors, then the malodor elimination capability is improved, but the fragrance strength deteriorates
Solution Approach 1:
The invention merges the malodor active ingredient and scented perfume into a single integrated composition where both components work together. The malodor active ingredient (e.g., zinc ricinoleate at 0.1-10% or zinc stearate at 0.1-10%) provides chemical neutralization of malodors, while the scented perfume (at 0.1-20%) provides fragrance strength and freshening effect. The synergistic combination ensures that malodor elimination and fragrance strength are both maintained without one compromising the other.
3Device complexity
If common perfume ingredients are used with dual function (masking and malodor reduction), then the product complexity is reduced, but the malodor reduction effectiveness deteriorates
Solution Approach 1:
The invention applies local quality by selecting specific malodor active ingredients with proven effectiveness against particular malodor types. Different metal soaps (zinc ricinoleate, zinc stearate, calcium ricinoleate, etc.) are chosen based on their specific affinity for neutralizing different malodor molecules. This targeted approach ensures high malodor reduction effectiveness while maintaining relatively simple product formulations.
Applied Scientific Principles
