Its scent profile is more refined and less sharp than raw petitgrain, making it ideal for balanced compositions.

Chemistry, Properties & Perfumer Guide

The Chemistry

Petitgrain oils, saponified, are derived from the hydrolysis of petitgrain oil, primarily composed of linalool and linalyl acetate. The saponification process breaks down esters into alcohols and acids, altering the scent profile. This synthetic modification enhances stability and solubility in aqueous formulations. The resulting mixture retains the key olfactory characteristics of petitgrain but with a smoother, less aggressive profile.
