Odor-Reducing Alcohol Compositions Without Fragrance Masking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for reducing unpleasant odors, such as those from human sweat, animal feces, and kitchen smells, often rely on masking with fragrances, which can limit the use of perfumes and products due to the need for specific scents and may not effectively neutralize odors without leaving a significant fragrance impression.
Innovation Solution
The use of a single alcohol or a mixture of alcohols of the formula (I), where one radical is hydrogen and the other is an acyl radical with 2 to 6 carbon atoms, to neutralize unpleasant odors without masking them with a distinct scent, allowing for the combination with various fragrances to create a wide range of scent options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If fragrance mixtures are used to mask unpleasant odors, then the odor is covered, but the selection of perfume types is limited and the fragrance itself becomes noticeable
Solution Approach 1:
The patent introduces a specific intermediary substance (2-acetyl-1,2,3,4,6,7,8-octahydro-2,3,8,8-tetramethylnaphthalene) that mediates between the unpleasant odor and the fragrance. This substance reduces unpleasant odors through a different mechanism than traditional fragrances, allowing it to work synergistically with various perfume types without competing for olfactory dominance, thus resolving the contradiction between odor reduction effectiveness and perfume selection versatility
2Object-affected harmful factors
If traditional fragrance mixtures are used to reduce unpleasant odors, then the odor is masked, but the fragrance leaves a significant scent impression
Solution Approach 1:
The patent employs a substance that creates an olfactory illusion rather than simply masking the original scent. This 'copying' approach tricks the olfactory system into perceiving reduced unpleasantness without replacing the original fragrance profile, allowing the true scent characteristics to remain while the unpleasant aspects are neutralized
3Object-affected harmful factors
If specially developed perfume oils are used to reduce unpleasant odors, then the odor is reduced, but the perfume has its own specific scent type limiting versatility
Solution Approach 1:
The patent identifies a substance with universal applicability that can be combined with any fragrance type or applied alone. This multi-functional substance works across diverse product categories (personal care, household cleaners, industrial products) and combines with various perfume oils without creating conflicts, thereby achieving both effective odor reduction and broad versatility
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
These alcohols effectively reduce unpleasant odors by interacting with olfactory receptors, creating an olfactory illusion that eliminates the perceived odor, and can be used in various products without discoloration or separation, offering a wide selection of fragrance types for odor-neutralizing and perfuming applications.
Implementation Method 1
These alcohols effectively reduce unpleasant odors by interacting with olfactory receptors, creating an olfactory illusion that eliminates the perceived odor

AI summary
The use described is (i)(a) of a single alcohol of formula (I) or (i)(b) of a mixture comprising or consisting of two or more different alcohols of formula (I), wherein one of the two residues Ra or Rb represents hydrogen and the other residue Ra or Rb represents an acyl residue with 2 to 6 C atoms, for the reduction of an odor or as an auxiliary substance for the reduction of an odor.
