Treemoss

Treemoss has a complex, earthy, and slightly bitter scent profile with deep woody, damp forest floor, and mossy green nuances. It offers a rich, dark, and slightly musty aroma that evokes the dampness of an ancient forest, with hints of bark, wet wood, and a slightly smoky undertone.

Origin and Extraction

Treemoss is a natural ingredient derived from various species of lichen that grow on tree bark, primarily in temperate and boreal forest regions. Traditionally, it was extracted through solvent extraction methods, though due to IFRA restrictions, synthetic alternatives are now more commonly used in modern perfumery.

History and Culture

Treemoss has been used in perfumery since the late 19th century, becoming particularly prominent in the classic chypre fragrances of the early 20th century. It was a key ingredient in iconic perfumes like Mitsouko by Guerlain and Miss Dior. However, due to potential skin sensitization concerns, its use has been significantly restricted by IFRA regulations in recent decades, leading to increased use of synthetic alternatives.

Chemistry and Molecular Structure

Treemoss contains complex compounds including evernic acid, usnic acid, and various phenolic compounds. These molecules contribute to its distinctive earthy, slightly bitter scent profile and provide its characteristic fixative properties in perfumery. The molecular structure includes various terpenes and polyphenols that create its unique olfactory characteristics.
