Science

Mechanism of Action

This ingredient leverages the natural properties of sunflower oil, delivering multiple skin benefits. Rich in Vitamin E, it provides antioxidative and anti-inflammatory protection, guarding against environmental stressors and premature skin aging. Its lecithin content aids in fortifying the skin's hydrolipid layer, while a high linoleic acid concentration facilitates easy skin penetration. This action contributes to maintaining a robust skin barrier, reducing transepidermal water loss (TEWL), and stimulating ceramide production for enhanced skin smoothness and deep hydration.

Stability

This ingredient functions as an effective emulsifier, enabling stable oil-in-water mixtures. While an explicit optimal pH range for the ingredient itself is not defined, emulsions containing similar esters have exhibited potential instability at acidic pH values (approximately 3.1-3.5) and elevated temperatures (e.g., 40°C) over time, primarily due to the hydrolysis of fatty acid esters.
