Science

Mechanism of Action

This ingredient reduces the interfacial tension between immiscible phases, allowing oil and water to form stable emulsions due to its balanced lipophilic and hydrophilic molecular structure. On the skin, it acts as an emollient by forming a protective layer that helps to reduce transepidermal water loss, thereby maintaining skin moisture, enhancing elasticity, and reinforcing the skin's natural barrier.

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that PEG Stearates, including related compounds, are safe for use in cosmetic formulations. This assessment was reaffirmed in 2005, and a previous caveat regarding use on damaged skin was removed in 2010, indicating broad safety. Typical concentrations in use are often below 4%, with some applications safely reaching up to 25% without observed irritation or sensitization.
