heather absolute

Heather absolute is a fragrance absolute known for its herbal scent, primarily used in fragrance agents and soluble in alcohol but not water.

General Material Description

Heather absolute is a type of fragrance absolute derived through solvent extraction that provides a characteristic herbal odor reminiscent of the heather plant. It is classified as an absolute due to its concentrated aromatic composition and typically appears as a viscous liquid. Known synonyms include "heather absolute (for fragrance) (Robertet)". Its chemical profile imparts a green, herbal note that is valued in perfumery for adding naturalistic plant nuances. The compound is documented in controlled-vocabulary sources such as PubChem. Heather absolute is generally obtained from the flowering tops of the heather plant and is prized for its distinctive olfactory properties in fragrance formulations.

Occurrence, Applicability & Potential Uses

Biologically, heather absolute originates from the flowers of the Calluna vulgaris species, commonly known as heather, which is native to Europe and Asia. Its principal application lies in the fragrance industry where it serves as a natural scent ingredient, enhancing herbal and green notes in perfume creations. The International Fragrance Association, IFRA (Global), provides guidance on the safe use of heather absolute specifically for fragrance purposes, with no recommended levels for flavor use as it is not intended for ingestion. This absolute contributes to complex compositions emphasizing natural floral and herbal characteristics.

Physico-Chemical Properties Summary

Heather absolute exhibits solubility in alcohol solvents, making it compatible with typical fragrance solvents and enhancing its integration into perfume bases. It is not soluble in water, which influences formulation strategies, especially when blending with aqueous components. The viscous nature and herbal scent profile are characteristic of its chemical constituents extracted from plant material. These physical and chemical traits assist perfumers in balancing heather absolute with other ingredients to achieve desired olfactory effects without compromising stability and miscibility.
