Bourgeonal opens with a burst of fresh, watery lily-of-the-valley — clean, dewy, and immediately recognisable. A bright aldehydic edge rides on top, giving it sparkle without harshness. Underneath, a quiet woody-sandalwood depth anchors the freshness and extends the drydown. This is the muguet note you build accords around. It slots naturally into aldehydic florals, green bouquets, and fresh compositions where you need a clean floral heart. Pair it with Hedione and hydroxycitronellal for a convincing lily-of-the-valley that reads as lifelike, not soapy. With Lilial no longer available in the EU, Bourgeonal covers similar muguet territory with its own greener, more openly aldehydic character. Evaluate from a 10% dilution; neat, the aldehydic top can mislead. Avoid pairing with Aldehyde C-11 (Undecanal) — it suppresses the muguet.
