ionone
Very LowTechnical/Scientific
Definition
Meaning
A chemical compound with a violet-like scent, used in perfumery.
Any of several isomeric ketones derived from terpenes, primarily alpha-ionone and beta-ionone, which are aromatic substances found in various plants and are key components in the fragrance of violets and other flowers. Beta-ionone is also a precursor to vitamin A.
Linguistics
Semantic Notes
The term is almost exclusively used in chemistry, biochemistry, and perfumery. It refers to a specific class of organic compounds, not a general concept.

- Using it as a general term for any fragrance.

FAQ
Frequently Asked Questions
It can be both. Ionones occur naturally in many plants (like violets and raspberries) but are also synthesized industrially for use in perfumes and flavours.
They are structural isomers. Alpha-ionone has a more floral, violet scent, while beta-ionone is woodier and is a key chemical building block for vitamin A.
It is highly unlikely you would need to, unless you are specifically discussing chemistry or perfume formulation. It is a specialist term.
In the concentrations used in perfumes and food flavourings, ionones are generally recognized as safe. However, like many fragrance compounds, they can cause allergic reactions in some individuals.
