treemoss concrete

Treemoss concrete is a natural concrete extract derived from lichens of the species Pseudevernia furfuraceae and Evernia furfuracea. This material presents as a viscous, dark resinous substance with a characteristic woody and tar-like odor that evokes forest moss and earthy notes. Known also as cedarmoss concrete or evernia furfuracea lichen concrete, it serves primarily as a perfuming agent in fragrances. The compound is sourced through solvent extraction of the lichens, resulting in a concentrated aromatic material used in the fragrance industry for its unique scent profile. Detailed chemical information and classifications can be accessed via its PubChem entry. Its natural origin and complex aroma profile make it a favored ingredient for creating woody, mossy accords in perfumery.

Treemoss concrete naturally occurs in lichens belonging to the species Pseudevernia furfuraceae and Evernia furfuracea, which grow primarily in temperate forest regions. In perfumery, it is valued for imparting woody and mossy scent characteristics that contribute to forest-like and earthy fragrance compositions. Its use is primarily as a fragrance agent, adding depth and complexity to fine fragrances and personal care products such as perfumes and colognes. The ingredient is subject to usage restrictions outlined in IFRA (Global) standards to ensure dermal safety due to its sensitization potential. Its applications extend to household care items where natural woody notes are desired, though flavor use is not recommended.

Treemoss concrete is a dense, viscous substance with a dark coloration typical of natural concretes extracted from lichens. Its chemical composition contributes to a woody, tar-like odor profile characteristic of forest moss materials. Stability and solubility properties facilitate its incorporation into fragrance matrices, typically blending well in oil bases and alcohol solutions. Lack of significant volatility at ambient conditions allows the aroma to persist over time in finished products. The compound's physical and chemical nature requires careful handling to maintain fragrance integrity during formulation and storage, aligning with regulatory safety parameters related to dermal sensitization risks.

	Notes:
IFRA FLAVOR REQUIREMENTS:
Due to the possible ingestion of small amounts of fragrance ingredients from their use in products in Categories 1 and 6, materials must not only comply with IFRA Standards but must also be recognized as safe as a flavoring ingredient as defined by the IOFI Code of Practice (www.iofi.org). For more details see chapter 1 of the Guidance for the use of IFRA Standards.
Recommendation for treemoss concrete flavor usage levels up to:
	not for flavor use.
