Organoleptic Properties:
Odor Type: green
Odor Strength:high ,
recommend smelling in a 0.10 % solution or less
green leafy nutty
Odor Description:at 0.10 % in dipropylene glycol. green leafy nutty
Odor and/or flavor descriptions from others (if found).
Pell Wall Perfumes
Leafy Pyrazine
Odor Description:green-leafy, grass, natural, nutty
As with all pyrazines this is used in tiny traces Leafy Pyrazine at 0.1% in DPG is quite nutty-brown smelling but on further dilution a green and leafy odour is realised. Mainly used in flavour work it can add original green notes to fragrance Even at this dilution this is a strong material that can enhance or contribute to green notes, diffusion and naturalness.
