Citronellal has a bright, sparkling aroma that evokes a feeling of freshness and vitality.
The scent is like a breath of invigorating citrus, mixed with a subtle sweetness and a hint of greenness, that stimulates your senses.
It is a monoterpene and an aldehyde (aldehyde of citronellol) and is a major constituent of citronella oil, which is often used as an insect repellent.
Citronellal is slightly less sweet-fruity than Citral.
Citronellal is a staple in fine perfumery, valued for its fresh, lemony-green scent and its ability to bring brightness and lift to fragrance compositions.
