Citronellal
Citronellal is a naturally occurring aromatic compound most famously found in citronella, lemon eucalyptus, and other citrusy botanicals.
It is celebrated for its bright, zesty, and green character that evokes freshly crushed lemon leaves with a subtle herbal twist.
In perfumery, citronellal is highly valued for its refreshing, aldehydic citrus note that feels both uplifting and clean.
It adds a sparkling top note that enhances freshness in colognes, fougères, and citrus accords, while also blending beautifully with lavender, neroli, and woody bases.
Its unique balance of lemony brightness and leafy greenness makes citronellal a versatile ingredient, bringing crisp clarity to compositions and providing an energising, natural freshness that lingers.
