Origin

Hydroxycitronellal is a synthetic compound produced through the chemical transformation of citronellal, which is itself derived from citronella or lemongrass oils. It does not occur naturally and is manufactured in controlled laboratory settings for use in perfumery.

Usage in Perfumery

Perfumers use hydroxycitronellal primarily in the heart of floral compositions, especially those aiming to evoke lily of the valley or muguet accords. It blends well with other floral notes, green notes, and light musks, and is valued for its ability to impart freshness and a naturalistic floral effect.
