Isobutyl Methyl Ketone

Description and usage notes:

Used to give an ethereal quality to fragrances, add ‘lift’ and is particularly useful where a fruity element is desired, where it can enhance the top note, giving a more juicy effect. Usage level is normally well below 1% of the fragrance concentrate.

Arctander describes it as having a: “Powerful and diffusive ethereal-fruity odor of poor tenacity.”
