rosemary concrete

Rosemary concrete is a natural aromatic extract obtained from the leaves of Rosmarinus officinalis, commonly known as rosemary. This concrete appears as a semi-solid, waxy substance with a strong herbal odor characteristic of the rosemary herb. It is sometimes referred to by synonyms such as rosmarinus officinalis concrete, rosemary oil, or rosemary leaf oil. The material is produced through solvent extraction of rosemary leaves, resulting in a concentrated aromatic product that captures the essential scent profile of the plant. Rosemary concrete serves as a raw material in fragrance compositions and is valued for its fresh, green, and slightly camphoraceous notes. It is typically sourced from cultivated rosemary plants across Mediterranean regions.

Rosemary concrete occurs naturally as an extract from the leaves of the rosemary plant, Rosmarinus officinalis. The distinctive herbal aroma arises from this botanical origin. It finds primary application as a fragrance agent in perfumery and scented cosmetic products due to its fresh and green odor characteristics. The compound's usage in formulations is guided by industry standards including IFRA (International Fragrance Association) regulations, which recommend maximum usage levels up to 5% in fragrance concentrates. Rosemary concrete is not advised for flavor use due to its composition and regulatory considerations. Its application enhances herbal and natural scent accords and is commonly used to evoke aromatic freshness in various personal care products.

Rosemary concrete exhibits a semi-solid consistency at ambient temperature, attributable to its waxy nature following solvent extraction from plant material. It is lipophilic, enabling good solubility in oils and alcohols, which facilitates its incorporation into fragrance compositions. The material's odor profile, identified as strongly herbal, results from a complex mixture of terpene and phenolic constituents. Toxicology data indicate low acute toxicity via dermal and oral routes, with oral rat LD50 values around 5000 mg/kg and dermal rabbit LD50 values exceeding 10000 mg/kg, suggesting a wide margin for safe use in controlled concentrations. The compound's physical and chemical stability allows it to retain aromatic properties during formulation but requires appropriate storage conditions to prevent degradation.
