Description

Citronellal is a classic citrus aroma chemical with a fresh, lemony-green and aldehydic character. It has a distinctive clean quality with subtle rosy, herbal and citronella-like nuances, making it an important material for creating natural-looking citrus and fresh-green effects. Compared with Citral, Citronellal is generally less sweet and fruity, giving it a sharper and greener character.

In perfumery, Citronellal is widely used to brighten fragrance openings and add freshness to citrus, floral, green and aromatic compositions. It is particularly useful in lemon, lime, grapefruit, citronella, lemongrass and fresh herbal accords. It can also act as a bridge between citrus top notes and floral heart materials, especially rose and geranium-type compositions. Its strong character means that relatively small quantities can have a noticeable effect on the overall fragrance profile.

Perfumers' Tip

Citronellal is powerful, so begin with a small amount when constructing an accord. Combine it with Citral and citrus oils for a bright lemon effect, or with Citronellol and Geraniol to create a fresh citrus-rosy character.
