Description

Adoxal® (chemical name: 2,6,10-trimethyl-9-undecenal) is a synthetic fragrance ingredient used to impart aqueous, ozonic, and juicy fruity notes to fragrance compositions. Its profile is very similar to Calone®, another widely used ingredient in the fragrance industry. This ingredient helps create fresh, clean scents reminiscent of sea breeze and crisp fruit, making it ideal for marine and aquatic fragrance compositions. Its molecular structure allows perfumers to build stable scent profiles with distinctive notes of freshness.

Additional information

The ozonic properties of Adoxal® can recreate the sensation of a sea breeze or fresh air after rain, bringing a clean, renewing quality to fragrances.
Adoxal® is often used as a core ingredient in marine and aquatic fragrances, shaping the distinctive character of many popular fresh perfumes released since the 1990s.
Adoxal® belongs to the aldehyde family, a class of chemical compounds that revolutionized modern perfumery by enabling innovative scent profiles that natural ingredients alone cannot achieve.
