2. Solutions for diffuse emissions of masking and neutralizing agents

How to navigate the commercial dialectic? Most product suppliers talk about odor neutralization, precipitation or even odor destruction. But on the one hand, it's hard to imagine a product being effective on every type of odor, or on all families of odor compounds, and on the other, the type of neutralization is not always specified. Is it physico-chemical neutralization? Or olfactory neutralization? Or worse, is it simply masking?

A neutralizer in the physico-chemical sense reduces the concentration of an odorous compound, a neutralizer in the olfactory sense reduces the number of odor units (see § ), while a masking agent is made up solely of pleasant-smelling compounds (lemon, strawberry, etc.) which are intended to outweigh the unpleasant odor.
