Alpha Ionone (CAS# 127-41-3) is a synthetic aroma chemical from the ionone family, renowned for its characteristic violet–orris floral note. Its scent profile combines soft violet petals, powdery orris, a hint of dry tea, light fruity nuances, and a gentle woody warmth. The overall effect is elegant and refined, with a classic floral character that still feels contemporary and versatile.

In perfumery, Alpha Ionone is used to build or reinforce violet and orris themes, as well as to modernize rose accords and other floral hearts. At low dosages, it softens sharp floral notes and creates a smooth bridge between citrus, floral, and woody components. At higher levels, Alpha Ionone can become a clearly defined violet–orris facet, ideal for floral, floral-powdery, chypre, and certain modern woody compositions.

Thanks to its good substantivity on skin and various bases, Alpha Ionone is widely used not only in fine fragrances but also in fragranced personal care, cosmetic products, soaps, detergents, and home care formulations. Its powdery violet character conveys a sense of cleanliness, grooming, and subtle romanticism, adding perceived quality and sophistication to the finished product.

With its distinctive yet flexible profile, Alpha Ionone is considered a near “must-have” in the perfumer’s palette, especially when working on violet, orris, modern rose structures, or whenever a refined, powdery floral touch is needed to complete and polish a fragrance.
