Trademarked toy scent
Hasbro obtained a U.S. trademark registration in 2018 for the specific scent of Play-Doh, treating the smell itself as a brand identifier for its modeling compound. The registered description refers to a sweet, slightly musky, vanilla-like fragrance with cherry overtones combined with the smell of salted, wheat-based dough.
