Grisalva (iff) smells like a rich, animalic amber with leather undertones.

IFF: The character of ambergris captured in a single chemical of remarkable strength. diffusive and long lasting. excellent performance/cost ratio
Grisalva is the ethyl analogue of ambrox, discovered by iff in the 1960's. generally, incorporation of an ethyl group in place of a methyl group increases the intensity of the parent chemical. one of the main key characteristics of grisalva is its exceptional diffusion.
