THE SCIENCE OF SCENT
What Makes Coumarin Special
Coumarin delivers a signature sweet, hay-like, vanilla-
tinged scent that's unmistakable. Found naturally in tonka 
beans, sweet clover, and grasses, this versatile compound 
has anchored fragrance design for decades.
While often synthetically produced for consistency and 
scale, coumarin's primary power lies in its olfactory impact
—elevating product experiences through carefully crafted 
aroma profiles.
