Science
Mechanism of Action
As a natural wax, Ouricury Cera primarily acts as a film-former, antistat, and viscosity modifier in cosmetic formulations, enhancing texture and stability. While the wax itself chiefly contributes these physical attributes, the parent plant, Syagrus coronata, contains beneficial compounds such as lauric acid, capric acid, and caprylic acid. These fatty acids are recognized for their antibacterial properties, achieved by disrupting bacterial cell membranes and interfering with cellular processes. Furthermore, extracts and oils from Syagrus coronata have demonstrated antioxidant and anti-inflammatory activities, suggesting a potential for broader skin benefits.

Key findings
- 01 An extract of Syagrus coronata demonstrated potent antimicrobial activity, inhibiting the growth of Leishmania amazonensis promastigotes, achieving 100% unviability after 60 minutes at a concentration of 50 µg/mL. It also significantly reduced the association index between macrophages and amastigotes of L. amazonensis by 70.4% at 33 µg/mL, and increased nitric oxide (NO) production by 158.3%.
- 02 The essential oil of Syagrus coronata exhibited antibiofilm activity against Staphylococcus aureus, with significant reductions in biofilm cell viability observed at concentrations exceeding 156 µg/mL, and reductions in the biofilm matrix at 312 and 624 µg/mL.
- 03 Syagrus coronata fixed oil (ScFO) administered orally in mice showed notable antinociceptive (pain-reducing) effects, decreasing abdominal writhing by up to 51.78% at 100 mg/kg. It also demonstrated anti-inflammatory potential, reducing ear edema by 63.76% and decreasing leukocyte and neutrophil migration, along with reducing IL-1β and TNF-α production at 100 mg/kg in acute inflammation and arthritis models.

Dusting Analysis
While Ouricury Cera is a functional wax, the active benefits (antimicrobial, anti-inflammatory, antioxidant) are primarily demonstrated by extracts and oils from the Syagrus coronata plant rather than the wax itself. Claims related to these active benefits should specify the source material (extract/oil) to avoid misrepresentation of the wax's direct efficacy.
The Formula
Formulation
Stability
Ouricury wax is a hard vegetable wax with a melting point ranging from 79-94 °C. It is hydrophobic and typically found as a thin layer on plant leaves, indicating good natural stability.
Conflicts
- In formulation with other waxes, particularly in polishes, concentrations exceeding approximately 16% of the total wax content can negatively impact gel strength and body strength, potentially leading to cloudiness or settling.
- Ouricury wax naturally possesses a greenish-brown color that is challenging to bleach, which is a key consideration for formulations desiring a light or clear final product.
Safety
Safety Profile
No specific safety assessments for Ouricury Cera have been conducted by CIR, SCCS, or FDA. However, Ouricury oil (from Syagrus coronata) demonstrated safety in acute oral toxicity studies in mice at 2000 mg/kg, showing no mortality or behavioral abnormalities over 14 days.

Verdict
Ouricury Cera is a valuable natural wax, providing excellent textural and film-forming benefits to formulations while offering a low risk of irritation or comedogenicity, with potential supportive antioxidant and antibacterial properties derived from its plant origin.
