The Full Story

A synthetic material designed to provide ozonic, fresh-metallic character in perfumery compositions. This material captures the electric, rain-fresh quality of ozone without the reactive instability of actual ozone.

The scent is sharp, fresh, and metallic — evoking the smell of air after a thunderstorm or near a waterfall. There is a clean, almost antiseptic quality and a subtle wateriness. Such materials are essential to the aquatic-marine fragrance family.

Did You Know?

Did you know?
The fresh smell after rain — petrichor — was named by Australian mineralogists Bear and Thomas in 1964, from the Greek 'petra' (stone) and 'ichor' (the fluid that flows through the veins of gods in Greek mythology).
