Sulfur-Compound Composition for Odor Masking Without Fabric Yellowing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current odor-masking products, particularly those using hydrocarbon-based propellants, are insufficient in reducing certain odors and can cause fabric yellowing due to oxidation, necessitating the search for alternative effective compounds.
Innovation Solution
A composition containing 1,8-para-menthenethiol and 3-mercaptohexyl acetate, potentially derived from plant extracts like Timur (Zanthoxylum armatum), is used to create deodorant products such as aerosols, candles, or diffusers, which effectively mask a wide range of odors through synergistic action.

Engineering Contradiction Analysis
1Speed
If hydrocarbon-based propellants are used in aerosol deodorizing products, then rapid diffusion of fragrance is achieved, but oxidation occurs causing fabric yellowing
Solution Approach 1:
The invention changes the chemical composition parameters by replacing hydrocarbon-based propellants with fluorinated propellants (HFA-134a, HFA-125, HFO-1234ze). This substitution maintains the rapid diffusion capability while eliminating the oxidation problem that causes fabric yellowing, as fluorinated compounds are oxidation-resistant
Solution Approach 2:
The invention uses a blend of fragrance compounds including aldehydes, alcohols, esters, and ketones that are designed to be effective at low concentrations and provide rapid masking action. The formulation allows for efficient use of fragrance materials that would otherwise be prone to degradation
2Reliability
If 1,8-para-menthenethiol is used as an odor masker, then some odor masking is achieved, but effectiveness is insufficient against certain odors
Solution Approach 1:
The invention combines 1,8-para-menthenethiol with 3-mercaptohexyl acetate in a synergistic formulation. The combination of these two sulfur-containing compounds produces an enhanced odor masking effect that is superior to either compound alone, particularly against difficult-to-mask odors. This merging of functionalities addresses the insufficient effectiveness of single compounds
Solution Approach 2:
The invention creates a composite fragrance formulation that integrates multiple compound classes (sulfur compounds, aldehydes, alcohols, esters, ketones) in specific proportions. This composite approach provides broad-spectrum odor masking capability across different odor types, enhancing versatility against various odor sources

AI summary
The invention relates to the use of a composition containing 1,8-para-menthene-thiol and 3-mercaptohexyl acetate, such as a plant extract and particularly a Timur (Zanthoxylum armatum) extract, as an odour-masking agent. The invention also relates to a deodorising product in the form of an aerosol, a candle or a perfume diffuser that has a wick or is electric, containing said composition.
