Rosmarinus Officinalis (Rosemary) Leaf Oil

Rosmarinus Officinalis Leaf Oil is a steam-distilled essential oil from Mediterranean rosemary plants, characterized by its fresh, herbaceous aroma and high content of bioactive compounds including rosmarinic acid, carnosol, and 1,8-cineole. Formulators value it not only for its distinctive fragrance but also for its potent antioxidant properties that can help stabilize formulations and protect against lipid oxidation, making it particularly useful in natural and preservative-free products. Its antimicrobial activity and scalp-stimulating properties make it especially popular in hair care formulations, though its potency requires careful usage levels (typically 0.1-1%) to avoid skin sensitization.
