Ionone Beta (β-Ionone) is a classic perfumery material with a violet–woody–ripe-fruity profile that feels soft and elegant. It opens with powdery purple-petal facets, then shifts into sun-ripened fruit (apricot, plum, peach) over a fine dry-wood nuance, leaving a warm, clean, and long-lasting trail.
In compositions, Ionone Beta is an excellent bridge between the heart and the base: it fleshes out floral–fruity accords while adding a dry-woody frame that stabilizes and balances diffusion. Its projection is gentle yet deep, lending a smooth, polished, modern character and taming harsh edges in the top notes.
Performance is reliable on skin and fabric, extending the life of the heart and rounding the overall structure. It blends well across multiple carriers (alcohol, hydroalcoholic bases, waxes, oils), is stable with most fixatives, and is easy to dose-ideal for skin-scent musks, classical florals, and contemporary fruit-wood signatures.
Belonging to the ionone/carotenoid family, it conveys a natural “sun-warmed fruit” tonality with a distinct violet pollen softness. At the right level, Ionone Beta smooths rough contours and imparts a subtle “soft-focus” finish to the fragrance.
Widely applicable in fine fragrance, body care, hair care, and home care, its agreeable, approachable character makes it easy for consumers to love. Used within the intended creative brief and relevant standards, Ionone Beta brings refined depth, quiet luxury, and everyday wearability.
