Science
Mechanism of Action
Pimenta racemosa leaf powder exerts its effects primarily through its essential oil and phenolic constituents. Terpenes like abietic acid and lupeol mediate its anti-inflammatory action by modulating neutrophil migration. Phenolic compounds, notably eugenol and hydrocarbon monoterpenes, provide antioxidant benefits by scavenging free radicals. Eugenol further contributes to its antimicrobial, antibacterial, and antiseptic qualities, aiding in acne prevention and impurity removal. Additionally, the ingredient demonstrates moderate inhibition of tyrosinase, an enzyme involved in melanin production, and possesses astringent qualities that may help prevent the appearance of fine lines, wrinkles, and skin sagginess.

Key findings
- 01 Topical application of Pimenta racemosa var. ozua aqueous extract significantly reduced TPA-induced ear edema in rats in a dose-dependent manner (0.5 to 3 mg per ear), indicating anti-inflammatory effects.
- 02 An 80% aqueous methanol extract of P. racemosa leaves demonstrated notable anti-inflammatory and antinociceptive effects in animal models (125 to 500 mg/kg b.wt.), alongside potent radical scavenging activity (SC50 = 4.6 μg/mL).
- 03 Pimenta racemosa leaf essential oil exhibited moderate inhibitory activity against tyrosinase (38.83 mg KAE/g), an enzyme crucial for melanin synthesis.
- 04 Essential oils from Pimenta racemosa effectively inhibited the growth of various microorganisms (MIC values from 20 to 400 μL/mL), highlighting its antimicrobial potential.

The Formula
Formulation
Stability
Active components include both oil-soluble essential oil constituents (predominantly eugenol at 57.84% to 70.87%, β-myrcene, D-limonene) and water-soluble phenolic compounds, contributing to its dual solubility profile and broad biological activity.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not evaluated this ingredient. EWG indicates that Pimenta Racemosa Leaf/Fruit Oil is allowed in EWG VERIFIED products but with restrictions, particularly for inhalable forms due to respiratory concerns. The International Fragrance Association (IFRA) restricts the use of eugenol (Max. Found: 40.00 %) and methyl eugenol (Max. Found: 1.4 %) due to their potential as sensitizers, both of which are prominent components. Acute toxicity studies on Pimenta racemosa var. ozua aqueous leaf extract reported moderate toxicity (LD50: 287 ± 12.9 mg residue/kg). Further toxicological, in vivo, and clinical studies are recommended for Pimenta racemosa leaf oil. The ingredient is compliant with EU Regulation (EC) 1272/2008 CLP Regulation regarding CMR category 1A or 1B substances.
