GAULTHERIA PROCUMBENS LEAF OIL.

Valuable CAS 90045-28-6 / FRAGRANCE, PERFUMING

Gaultheria Procumbens Leaf Oil, extracted from the Wintergreen plant, is a potent botanical known for its remarkably high methyl salicylate content (96.9–100%). This precise composition delivers significant anti-inflammatory, analgesic, and antimicrobial benefits, making it a powerful, albeit carefully managed, asset in targeted skincare formulations.

Science

Mechanism of Action

The primary mechanism of Gaultheria Procumbens Leaf Oil stems from its concentrated methyl salicylate, which provides aspirin-like effects upon topical application. It absorbs into the skin to reduce localized pain, swelling, and muscle tension by inducing a warming sensation and enhancing blood circulation. Beyond its analgesic properties, it acts as an effective antimicrobial agent against bacteria and fungi, offers astringent benefits by constricting pores, and helps regulate excess oil and minimize skin redness. Additionally, the oil contributes antioxidant and photoprotective activities, promoting cellular renewal through purifying and exfoliating actions.

Caution
Sensitization risk High

Wintergreen oil is considered possibly safe for topical use when adequately diluted, though a high irritancy potential exists, and some individuals may experience irritation. Internal consumption is strictly contraindicated due to the extreme toxicity of methyl salicylate; ingestion of as little as 6 mL can be fatal. It complies with EU regulations (EC) No 1223/2009 for cosmetic application.
