Definicija

Dewy lily-of-the-valley, green and aqueous. A single molecule that smells like wet flowers on a cold morning — sharp, clean, with a metallic freshness.

Miris

Intensely dewy, green-floral, with a lily-of-the-valley character that is more aqueous and metallic than hydroxycitronellal. At low doses: fresh, transparent, wet petals. At high doses: sharp, almost cucumber-aldehydic. Less sweet than hydroxyisohexyl 3-cyclohexene carboxaldehyde (HICC), less powdery than butylphenyl methylpropional, with a clean coldness unique to this molecule.

Detaljno

Bourgeonal (3-(4-tert-butylphenyl)propanal, CAS 18127-01-0) is a synthetic aldehyde with a powerful lily-of-the-valley character. It is a common muguet chemical in contemporary use, known for strong diffusion and realistic dewy-floral effect.

The scent is intensely green-floral, watery, and slightly metallic — like crushing a fresh stem of lily-of-the-valley between wet fingers. It is more aqueous than hydroxycitronellal (the classic muguet molecule) and less creamy, with a colder, more transparent quality. At high concentrations it becomes almost cucumber-like.

Bourgeonal is also notable for its role in reproductive biology research: it acts as a chemoattractant for human sperm cells, which carry olfactory receptors that respond to this specific molecule. This discovery, published in Science in 2003, made it briefly famous outside perfumery circles.

Zanimljivosti

In 2003, researchers at Ruhr University Bochum showed that human sperm cells carry an olfactory receptor, hOR17-4, that bourgeonal activates strongly, and that sperm swim towards bourgeonal in laboratory tests. The authors concluded that the receptor may play a part in fertilization.

U parfemima

Bourgeonal is a heart note and a key building block for muguet (lily-of-the-valley) accords. It provides the dewy, aqueous quality that makes synthetic muguet compositions convincing. Works alongside Hydroxycitronellal, butylphenyl methylpropional (banned in the EU, CosIng II/1666), and hydroxyisohexyl 3-cyclohexene carboxaldehyde (HICC; banned in the EU, Annex II entry 1380, Regulation (EU) 2017/1410). Its strong diffusion makes it useful at low concentrations as a freshness booster in floral, green, and aquatic compositions.
