Science

Mechanism of Action

As a modified ester of sunflower oil, this ingredient primarily functions as an emollient, promoting skin smoothness and hydration while strengthening the skin's natural barrier. It is understood to confer the antioxidant and anti-inflammatory benefits associated with Vitamin E, safeguarding skin cells from oxidative damage and premature aging. Its notable linoleic acid content is crucial for maintaining the skin's hydrolipid layer, optimizing moisture retention, and exerting anti-inflammatory effects upon topical application. Furthermore, it may contribute to a balanced skin microbiota, supporting overall dermal health and potentially aiding in wound recovery.

Stability

Emulsions containing this ingredient demonstrate optimal stability at an acidic pH range, specifically between 3.4 and 3.5. Stability can be compromised at higher temperatures (e.g., 40°C), where a decrease in pH may occur due to the hydrolysis of fatty acid esters. To prevent oxidation and the potential formation of toxic aldehydes, it is crucial to store the ingredient in a cool, dry, and light-protected environment.
