The essence of sweet orange is obtained by cold expression of the zest of orange. It is mainly made of limonene. Orange is found in Eaux de Cologne because it releases a fresh smell, very sour and sweet. It belongs to the citrus olfactory family. Its notes are light, therefore more volatile, and are generally associated with more animal notes to fix them. Orange is often used in top notes as in our perfume made of amber so or in kilim for its sweet facets.
