Reodorant

Care must be taken never to use a reodorant to mask or cover up a toxic concentration of gas.

Some new material, the mask or reodorant which has something in common with the unwanted odour is added, eg an acid odour can be built up to a fruity note.

Aromatics, sometimes referred to as reodorants, are added to fabric sizing to disguise the glue or casein smell, leaving the product with a fine fresh odor.
