The marriage of sparkling aldehydes and delicate flowers creates a family of soft, often powdery, abstract florals. Aldehydes are found naturally in rose and citrus oils, but in such minute amounts that they have to be re-created in the laboratory. Their natural scent is not pleasant: some have a sharp, metallic fragrance, others the burnt, waxy aroma of a just snuffed candle. Add them to flowers, however, and their subtle magic makes the blossoms sing. Their soprano notes are muted by the powdery accents of iris and vanilla to create a fragrance that is both soft and flowery. - Michael Edwards Fragrance Wheel
