Hydrolysable profragrances increased measured fragrance concentrations above cotton after one and three days, without testing perceived strength or consumer preference.

Researchers coated activated carbon with titanium dioxide and a polymer, tested adsorption of five odor compounds, and evaluated a WAC-containing spray in eight people over six hours.

Improved cultured-cell assays revealed receptors for grapefruit and other signature odorants. Ambrox stereoisomers also showed why more than one receptor can matter.

A study found that peppermint and other oils harmonized better with model fecal odor than floral extracts. Combining them with receptor-suppressing materials was explored to reduce unpleasantness in complex model odors.
