Abstract

This article focuses on investigating the masking of the malodor iso-valeric acid (IVA), a compound associated with unpleasant human sweat odors, using sub-threshold concentrations of various masking agents. Using Sniff olfactometry (SO) with brief 70 ms stimulations, the study tested seven perfume raw materials (PRMs) individually and in mixtures to assess their ability to reduce IVA recognition among nine subjects. Results showed that single masking agents decreased IVA recognition probability by 14–72%, while a mixture of six sub-threshold masking agents reduced recognition by 96%, effectively rendering IVA unrecognizable. The study distinguishes between "odor covering" (using supra-threshold pleasant odors) and "odor masking" (using sub-threshold amounts), discusses dose-dependent effects, habituation to IVA, and proposes potential receptor-level and neural coding mechanisms underlying odor masking.
