A study of 57 customers at a second-hand clothing store found higher reported spending during a linen-scent period. Comparing it with another similarly pleasant scent highlights the meanings connecting scent and products.

Fifty-eight people evaluated recycled-material bottles containing unscented shampoo. The relationship between odor pleasantness and willingness to buy reveals packaging challenges that environmental information alone did not resolve.

Researchers washed T-shirts worn by 31 people and dried them in two environments. Changes in odor compounds and bacteria offer clues to why smells return after washing.

Does the release of odor compounds absorbed from artificial sweat depend on clothing material? A study of six fibers from 30 minutes to 24 hours explores differences between materials, times, and compounds.

Can adding vanilla aroma make milk taste sweeter without more sugar? A study in which 108 people evaluated 18 formulations examined the two-way relationship between sweetness and vanilla flavor, and the difference between synergy and liking.

Adding fragrance diffusers may increase airborne compounds without increasing perceived strength proportionally. A study comparing zero to five electric diffusers also examined the difference between readily measured compounds and those responsible for perceived scent.
