Answer 1

Besides the scent, they also contain chemical that “fix” the scent to the skin, so that it is released more slowly into the air. Traditionally, it was something called ambergris, which is from sperm whale vomit (literally). Now it’s just synthetic chemicals, since it is generally frowned upon to kill whales for their puke.
