Chemistry, Properties & Perfumer Guide
The Chemistry
Cedryl methyl ether is a synthetic aromatic ether derived from cedarwood components. While not found in nature, it mimics the woody character of natural cedarwood constituents. The compound is typically synthesized through methylation of cedrol or related cedarwood alcohol derivatives. Its molecular structure features an ether linkage that contributes to its stability and moderate volatility in fragrance applications.

| “Its odor type is not exactly a rare one, and it tends to put rather narrow limits to the application of this ether. It will inevitably de- tract from the amount of sweetness already present in a composition, but it is stable and non-discoloring in soaps and powders, etc.”📖 Arctander | |
