Chemistry & Uses

Uses in perfumery :

According to its olfactive weakness, this woody and ambery molecule is less used than some others. Amberketal® can be used in woody-ambergris notes and especially in functionnal products thanks to its stability.

Year of discovery :

Discovered in 1953.

Natural availability :

Amberketal® is not available in its natural state.

Isomerism :

Amberketal has got five asymmetric carbons, forming a few possible isomers. Nevertheless, only a mix of these isomers is used in perfumery.

Synthesis precursor :

Amberketal® is not a precursor to the synthesis of another compound of olfactory interest.

Synthesis route :

Amberketal® is synthesized from manool, a natural component extracted from ''pink pine '' tree Halocarpus biformis, growing in New-Zealand. One of Manool's double bond is epoxidized, subsequent oxydative degradation of the allyl alcohol function into a ketone, and an intramolecular acetalization, giving birth to the final ketal function.

Stability :

Stable in perfumes and diverse functional bases, except very acid products and bleach.

Other comments :

Most of the time, Amberketal® is diluted at around 10% in Isopropyl Myristate or Dipropylene Glycol for solubility and use reasons.
