A soft, diffusive floral-green material with a fresh magnolia-like character and a subtle fruity-waxy undertone. Cleaner and less ionone-like than pseudoionone, it lends a natural, transparent floralcy reminiscent of freesia, muguet and cyclamen. Rounded and airy in feel, without the violet-woody nuance of the ionones.AI · claude-opus-4-7

The title ketone finds some use in rose compositions, where its peculiar oily softness lends very pleasant and natural notes, and also supports mildly green notes in the composition. It blends furthermore excellently with vetiver and labdanum, musks and lavender products, and it can justly be classified as a very versatile perfume chemical.
The title material is used in small amounts in berry flavors, fruit complexes, etc. at the rate of 1 to 15 ppm in the functional consumer products.
Although the material can be made by regulated hydrogenation of pseudo-ionone, this method may lead to a mixture of hexahydropseudo-ionone, tetrahydro-pseudoionone, and possible an isomer of geranyl acetone. Other methods use linalool plus acetic anhydride with sodium ethoxide, followed by regulated hydrogenation. It has also been prepared from geraniol via geranyl chloride.
