Odour profile

Powdery violet and orris with a soft woody undertone.

Key facts

Typical usage

Typical level in a fragrance concentrate: 2–15%. These are starting points, not limits. In finished products, dose the complete fragrance oil at the normal level for that product (for example around 15–25% in an alcohol perfume, 6–10% in candles and 1–3% in soap).

Blends well with

Heliotropin, Coumarin, Vanillin, Iso E Super, musks and rose notes. See all aroma chemicals.

Tips

• Add a little to rose or iris accords for a powdery finish.
• Works well with Iso E Super for a velvet woody-floral.
