Odor-Reducing Alcohols for Low-Fragrance Odor Neutralization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for reducing unpleasant odors, such as those from human perspiration, animal waste, cooking, and tobacco smoke, are inadequate as they often rely on masking the odor with fragrant substances, which limits the choice of fragrance types and can be ineffective in completely eliminating the odor.
Innovation Solution
The use of specific alcohols of formula (1) or mixtures thereof, which interact with olfactory receptors to misperceive the odor, reducing its intensity without adding a significant fragrance, allowing for a broader range of fragrance options and effective odor neutralization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If fragrant substances are used to mask unpleasant odors, then the odor is reduced, but the choice of fragrance types is limited and the odor is not completely eliminated
Solution Approach 1:
The patent introduces a specific intermediary substance (2-acetyl-1,2,3,4,6,7,8-octahydro-2,3,8,8-tetramethylnaphtaline or iso E super) that acts as a mediator between the unpleasant odor and the olfactory receptors. This substance selectively interacts with the receptors to reduce the perception of unpleasant odors without imposing a strong fragrance of its own, thereby allowing a broader range of fragrance types to be used in the composition.
2Object-affected harmful factors
If strong fragrant substances are used to reduce unpleasant odors, then the odor is masked, but the preparation has its own strong fragrance that may not suit all applications
Solution Approach 1:
The patent applies the principle of local quality by using a substance with very specific and selective olfactory properties. The iso E super has a particular molecular structure that allows it to interact selectively with certain olfactory receptors responsible for detecting unpleasant odors, while having minimal interaction with receptors that detect pleasant fragrances. This creates a localized effect on odor perception without imposing a strong overall fragrance.
3Object-affected harmful factors
If conventional perfume oils are used to combat unpleasant odors, then the odor is masked, but the consumer choice of fragrance types is restricted
Solution Approach 1:
The patent segments the odor control function from the fragrance function. Instead of using substances that perform both functions (masking odor and providing fragrance), the invention uses a dedicated odor-reducing substance (iso E super) that specifically targets unpleasant odor molecules, thereby separating the odor control mechanism from the fragrance provision mechanism. This allows different fragrance types to be independently selected and combined with the odor-reducing substance.
