Science
Mechanism of Action
This ingredient operates on the skin by adhering exogenous lipids to intercorneocyte clusters, thereby improving the skin's barrier properties and hydration. It forms a protective film on the skin's surface, effectively reducing transepidermal water loss and preventing dehydration. Furthermore, it acts as a surfactant, lowering the surface tension of the stratum corneum to facilitate the removal of dirt and impurities, and its sesame oil origin contributes to antioxidant and anti-inflammatory effects.

Stability
The molecular structure, combining fatty acids from sesame oil with Polyglyceryl-6, confers inherent stability and functional versatility. This allows it to enhance the texture and overall stability of cosmetic formulations. While specific optimal pH ranges were not identified, the acid value of its base sesame oil influences its pH-related quality.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel assessed a group of 274 polyglyceryl fatty acid esters, including SESAME OIL POLYGLYCERYL-6 ESTERS, concluding they are safe for cosmetic use at current concentrations when formulated to be non-irritating. While no specific maximum concentration was provided for this exact ester, related polyglyceryl fatty acid esters have been noted in leave-on formulations at concentrations up to 39-40%. It is generally considered safe and non-irritating.
