Don’t take our word for it. Here’s every fact on this site, with its evidence grade, its caveats, and a link to the source, so you can check us.
We start you on the strong ones: findings that have been replicated or come from one large, well-controlled study. Moderate and weak facts are here too, labeled for what they are. Use “Link to this fact” to share a single card.
Indoor air / Other evidence
On cotton and polyester, fabric held more fragrance on cotton than polyester at 1 hour (geraniol about 182 vs 50 µM/g, eugenol about 261 vs 59), but the musk stayed several times higher on cotton at every time point.
Weak evidence: The paper's highlight says the fibers recovered similar amounts; its own Table 3 shows the musk gap persists. Room temperature only, one cotton and one polyester T-shirt, n = 3.
