What it does
Methyl 2-octynoate, also called methyl heptine carbonate, is a fragrance ester with a sharp green, violet-leaf note. It is one of the 26 fragrance ingredients the EU requires to be listed by name above trace levels because sensitization has been documented, and the fragrance industry's own IFRA standards additionally cap its use level. It is a scent ingredient with no function for the skin.
