IONONE BETA (β-Ionone) – floral-woody note (violet/iris) with fruity accents

BETA IONONE (β-Ionone)
A key ingredient in violet-iris accords with fruity and woody nuances. Its profile combines floral and powdery notes of violet/iris, woody and earthy touches, and a fruity base of raspberry/cassis, ideal for adding roundness and body to compositions. It is a heart-base note with good staying power.

How to use it

• Perfect in violet reconstructions and in floral-fruity accords (blackcurrant, blackberry), where it gives an elegant powdery effect.
• Excellent binder in olfactory pyramids; excellent in combination with Bergamot OE , Hedione® and β-Damascone for “tea” accords.
• It pairs well with α-Ionone and fruity aromachemicals (e.g., frambinone/fructone) to create a convincing raspberry effect; also popular in classic “lipstick” notes.
