Science
Mechanism of Action
Operating as a nonionic surfactant, POLYGLYCERYL-10 PENTASTEARATE enables the homogeneous dispersion of oil and water phases, ensuring product consistency and stability. On the skin, it forms a thin, protective film that reduces transepidermal water loss, thereby boosting hydration and promoting a smoother skin texture. Additionally, it contributes to formulation viscosity as a thickener and aids in component dispersion.

Stability
This lipophilic, nonionic surfactant demonstrates robust stability against both salt and acid, making it suitable for various formulations. It presents as a waxy solid, typically melting between 55.0°C and 58.0°C, and is incorporated into the oil phase. Its strong hygroscopic properties facilitate easy dispersibility in water and enable the creation of stable oil-in-water (O/W) emulsions and lamellar structures by effectively trapping water.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel assessed 274 polyglyceryl fatty acid esters, including Polyglyceryl-10 Pentastearate, concluding they are safe for cosmetic use at current practices and concentrations when formulated to be non-irritating. While no specific maximum concentration for Polyglyceryl-10 Pentastearate was established, regulatory bodies like the U.S. FDA and the EU's Cosmetic Directive permit its use, subject to general cosmetic ingredient limitations.
