GENERAL DESCRIPTION & APPLICATIONS

Ionone is a member of terpene, naturally occurring unsaturated hydrocarbons whose carbon skeletons are composed exclusively of isoprene C5 units (CH₂=C(CH₃)-CH=CH₂), consisting of five carbon atoms attached to eight hydrogen atoms (C₅H₈). The stepwise distillation with water and carbonates yields terpenes. Ionone is one of major aroma components of rose oil absolute which is the most widely used essential oil in perfumery. The major contributors to the perfuming ingredients of rose oil are rose ketones and rose oxide.

Rose ketones are the precursors of many important flavors and fragrances and being used in the creation of new type perfumes.

Ionone is a clear to yellowish liquid; boiling point 126 - 128 C at 12 mmHg; soluble in alcohol, ether, and mineral oil. It is used is used in perfumery, flavoring, and vitamin A (retinol) production for cosmetics and toiletries. beta isomer shows a less floral odour than the alpha.

It has good substantivity and is used in all areas of perfumery. (Olfactive Note: Floral, Woody, Raspberry Seed, Violet).
