Concrete Candle Olibanum

Olibanum, also known as Frankincense is obtained from trees of the genus Boswellia. Olibanum has a fresh balsamic, somewhat green, woody and spicy fragrance with a fruity top note.

Concrete, in perfumery, is a semi-solid mass obtained by solvent extraction of fresh plant material.

Fresh plant material is extracted with nonpolar solvents (e. g., benzene, toluene, hexane, petroleum ether). On evaporation of the solvent, a semi-solid residue of essential oils, waxes, resins and other lipophilic (oil-soluble) plant chemicals remains.
