Citronellal

Citronellal is a widely used fragrance ingredient valued in perfumery for its fresh, lemony, and slightly green character. Its scent profile is typically described as bright, crisp, and naturally citrusy, evoking the aroma of lemongrass and citronella, with subtle floral and herbaceous nuances that add complexity to its freshness.

The material usually appears as a clear, colorless to pale liquid with low viscosity, and is appreciated for its strong diffusion and lively freshness in fragrance compositions. Its character is clean and vibrant, making it particularly effective for creating a sharp and natural citrus impact in the top of a fragrance.

Citronellal is especially valued for its ability to deliver a natural, green-citrus freshness that feels both refreshing and slightly aromatic, bridging the gap between citrus and herbal accords. It is naturally present in essential oils such as citronella and eucalyptus citriodora, which contributes to its characteristic profile.

In practical perfumery, Citronellal is frequently used to build citrus, green, and aromatic accords, while also adding freshness and lift to cologne-style and modern clean fragrances. It blends particularly well with lemon, lime, bergamot, lavender, eucalyptus, and green notes, making it a key component in fresh citrus perfumes, aromatic compositions, and functional fragrances.
