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 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.


alpha-Ionone	beta-Ionone

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