SUNFLOWER SEED OIL POLYGLYCERYL-6 ESTERS.

Valuable CAS - / EMULSION STABILISING, SURFACTANT - EMULSIFYING

Sunflower Seed Oil Polyglyceryl-6 Esters is an advanced derivative of sunflower seed oil, engineered to enhance emulsification, skin conditioning, and moisturization. It effectively stabilizes oil-in-water formulations while delivering essential fatty acids and antioxidants to support skin barrier integrity and hydration.

emollient emulsifying skin conditioning surfactant emulsion stabilising

Science

Mechanism of Action

This ingredient is formed through the transesterification of sunflower seed oil with Polyglyceryl-6, which amplifies its amphiphilic properties. It functions as both a surfactant and an emulsion stabilizer, enabling the stable blending of oil and water phases in formulations. On the skin, its sunflower seed oil component provides a rich source of linoleic acid and Vitamin E. Linoleic acid is critical for reinforcing the skin barrier, mitigating transepidermal water loss (TEWL), and stimulating ceramide and other lipid synthesis. Vitamin E contributes antioxidant and anti-inflammatory benefits. Together, these components help form a protective film on the skin's surface, enhancing hydration and preventing moisture evaporation.

Stability

This ingredient is readily soluble in oils and organic solvents, and dispersible in water, facilitating its integration into diverse cosmetic formulations. Being an amphiphilic, non-ionic, and water-dispersible oil, it serves as an effective emulsion stabilizer, contributing to enhanced product stability. While specific pH stability data for this exact ester are not extensively detailed, related sunflower oil derivatives have shown stability in acidic pH ranges (approximately 3.5 ± 0.1) over a 90-day period.
