What it is

Rosemary leaf oil is steam-distilled from Rosmarinus officinalis, now botanically reclassified as Salvia rosmarinus. Depending on chemotype it is rich in 1,8-cineole, camphor, alpha-pinene and limonene. It should not be confused with rosemary leaf extract, which contains the antioxidants carnosic acid and rosmarinic acid and behaves quite differently.

What it does well

  • Contributes mild antioxidant activity

    Rosemary compounds scavenge free radicals in laboratory tests, though the non-volatile extract is a far better antioxidant than the essential oil. At fragrance levels the contribution is small.

    Limited evidence

Worth knowing

  • Contains several declared allergens even though the oil itself is not listed

    Rosemary oil is not named in the EU fragrance-allergen list, but its limonene, linalool, camphor and pinene content can push those individual substances over the labelling threshold. Camphor and pinene both joined the list under Regulation (EU) 2023/1545.

    Matters most toPeople with a terpene or fragrance allergy who are checking labels.

Where the EU stands

No specific restriction

Rosemary leaf oil is not listed in Annex II or on the Annex III fragrance-allergen labelling list, so there is no maximum concentration and no direct labelling obligation. Individual constituents such as Limonene, Linalool, Camphor and Pinene must still be declared if they exceed the thresholds.
