How Melafleur is used
Used in muguet and fresh floral accords for an airy, green-melon lily of the valley.
Typical role: modifier (used in small amounts to change the character of a blend).
How Melafleur differs from similar materials
- Hivernal Neo
- Hivernal Neo is the more aldehydic, laundry-clean muguet; Melafleur is greener, with a melon and ozone air.
- Acetaldehyde Ethyl Linalyl Acetal
- The ethyl linalyl acetal is a herbal, fresh muguet from linalool; Melafleur is greener and more ozonic, with melon.
Each difference compares the published descriptions of the two materials. Smell varies with grade, supplier and dilution; compare them side by side on blotters before substituting one for another.
