Title: Concrete

Concrete is a highly concentrated, waxy substance obtained through solvent extraction of botanical materials. This fragrant material is created by immersing plant materials, such as flowers, leaves, or roots, in a solvent like hexane. The solvent dissolves the aromatic compounds, along with waxes and other lipophilic (fat-loving) substances. After the solvent is evaporated, what remains is a semi-solid, waxy substance known as concrete.

Concretes are known for their rich, full-bodied aroma, capturing a wide spectrum of the plant's scent profile, including some of the more delicate and volatile top notes that may be lost in steam distillation. They are typically used as an intermediary product in the production of absolutes, which are further refined to remove the waxes and non-fragrant components.

Due to their concentrated nature, concretes are used sparingly in natural perfumery, providing depth and longevity to fragrance compositions. They are particularly valued for their ability to impart a true-to-nature scent, closely resembling the aroma of the fresh plant material. Concretes can be used directly in perfumery or further processed to obtain an absolute, which is a more refined and liquid form of the essence.

In summary, concrete is a solvent-extracted, waxy substance from botanical materials, prized for its rich and authentic aromatic properties in natural perfumery.
