Science
Mechanism of Action
This ingredient operates via multiple pathways to enhance skin health. It functions as an antioxidant, neutralizing reactive oxygen species to mitigate oxidative stress. Its anti-inflammatory action targets key pathways like nuclear factor-kappa B and Mitogen-activated protein kinase, which can help soothe irritated skin. Sodium Ursolate promotes collagen synthesis and inhibits matrix metalloproteinases, thereby combating photoaging and preserving skin elasticity. Furthermore, it supports wound healing by stimulating keratinocyte proliferation and extracellular matrix remodeling, potentially regulating skin lipid metabolism to improve barrier function and hydration. It also influences collagen homeostasis by both inhibiting its production via TGF-β/Smad impairment and stimulating its degradation through MMP-1 via the MAPK pathway, indicating a complex role in collagen remodeling.

The Formula
Formulation
Stability
Ursolic Acid Na-Salt natural exhibits stability for two years when stored optimally in dry, sealed, and light-protected conditions at temperatures between 10°C and 25°C. For dissolution, moderate heating up to 40°C with stirring is advised, particularly in solvents like Ethanol, Phenethyl Alcohol, Pentylene Glycol, and Propylene Glycol, where it shows approximately 1% solubility. Prior dispersion in oil is a feasible formulation approach, as it is nearly insoluble in water.
Safety
Safety Profile
The pure raw material (Ursolic Acid Na-Salt natural) has been identified as irritating to the eyes. However, it is generally regarded as non-hazardous at typical concentrations used in cosmetic formulations. While Ursolic acid, its parent compound, has demonstrated high safety in intravenous clinical trials, this data cannot be directly extrapolated to the topical application safety profile of Sodium Ursolate.
