thyme concrete

Thyme concrete is a natural extract obtained from the plant Thymus vulgaris. This substance appears as a semi-solid aromatic mass with a characteristic herbal odor, closely resembling thyme herb in scent profile. Synonyms include "thymus vulgaris concrete," emphasizing its botanical origin. The compound is classified as a concrete, a type of aromatic extraction capturing lipophilic fragrant substances. It is extensively studied and cataloged in chemical registries such as PubChem, which provides structural and physicochemical data. Thyme concretes are traditionally derived by solvent extraction from fresh thyme flowers and leaves, concentrating the essential aromatic compounds while retaining characteristic herbaceous olfactory notes.

Thyme concrete originates biologically from the thyme plant, Thymus vulgaris, a member of the Lamiaceae family known for its aromatic leaves. The extract captures a blend of volatile and non-volatile constituents responsible for thyme's distinctive herbal aroma. Its primary application lies in the fragrance industry, where it serves as a natural aromatic ingredient imparting herbal and green notes. Thyme concrete is generally designated for fragrance use rather than flavor applications, consistent with IFRA (Global) standards, which provide guidelines to ensure safe usage levels in consumer products. Its potent herbal character supports its inclusion in perfumes, soaps, and aromatic preparations requiring a natural herbal scent.

Thyme concrete is characterized by its semi-solid consistency at ambient temperature, typically exhibiting a viscous texture rich in aromatic compounds soluble in lipids. The compound contains a complex mixture of terpenes, phenolic derivatives, and other volatile substances, which lend it a robust and persistent herbal odor. Its physicochemical profile supports its solubility in organic solvents and fats, making it suitable for fragrance formulation. Thyme concrete's stability and odor profile depend on storage conditions, with susceptibility to oxidation influencing shelf life. The absence of identified hazards simplifies handling precautions, although regulatory guidance limits its usage to fragrance formulations.
