Science
Mechanism of Action
This ingredient primarily functions as a nonionic surfactant and emulsifier, enabling the stable dispersion of immiscible oil and water phases to form consistent emulsions. On the skin, it delivers a softening and lubricating effect as an emollient. As a derivative of Polyethylene Glycol (PEG), it contributes to skin hydration by drawing and retaining moisture, thus acting as a humectant. PEGs can also facilitate the penetration of other ingredients into the skin, with the extent influenced by factors like molecular weight and skin condition.

Stability
PEG Stearates demonstrate good stability against heat, acids, and bases. Related compounds show stability across a broad pH range, typically between 3.5 and 9.0.
Safety
Safety Profile
The Expert Panel for Cosmetic Ingredient Safety (CIR) concluded that PEG Stearates, including PEG-36 Stearate, are safe for use in cosmetics, reaffirming its conclusion in 2005. The CIR Panel specifically removed the prior caveat against using PEGs on damaged skin. This ingredient is also listed in the FDA's Voluntary Cosmetic Registration Program (VCRP).
