yarrow oil

Yarrow oil, also known as achillea millefolium L. oil, is an essential oil extracted from the flowering herb of the yarrow plant, belonging to the Asteraceae family. It is recognized for its medium-strength herbal odor characterized by green tea, chamomile, rosemary, floral, creamy, fatty, woody, and weedy notes. The flavor profile similarly encompasses herbal, woody, tea, tobacco, hay, weedy, grassy, and beeswax nuances. Synonyms include achillea coronopifolia oil and milfoil oil (achillea millefolium). This oil is produced mainly through steam distillation of the aerial parts during flowering. The compound is indexed under PubChem and is sourced primarily from wild or cultivated yarrow plants in temperate regions.

Yarrow oil naturally occurs in the flowering herb of the Achillea millefolium plant. It is applied extensively as a flavor and fragrance agent in various formulations, imparting herbal and floral character. In cosmetics, it serves multiple roles including as an antidandruff, cleansing, refreshing, soothening, and perfuming agent, as well as a tonic. Its inclusion in chamomile-type odor applications is noted. Regulatory frameworks such as IFRA (Global) provide usage guidelines to ensure fragrance safety and limit sensitizing components. This oil's versatility in flavor and fragrance industries highlights its value in natural product formulations.

Yarrow oil exhibits a specific gravity of approximately 0.92 at 25 °C, indicative of its density relative to water. It has a flash point of 54 °C (129 °F), a parameter critical for handling and formulation safety considerations. The oil is soluble in alcohol and shows limited water solubility, estimated at around 332.1 mg/L at 25 °C. These characteristics influence its behavior in different matrices, affecting volatility, blending compatibility, and stability in finished products. The solubility profile supports its use in alcohol-based formulations typical in cosmetics and perfumery. Overall, its physicochemical traits support its function as an aromatic oil with moderate substantivity.
