Mechanism of Action
This ingredient functions through a dual mechanism. The PEG (Polyethylene Glycol) component actively draws and retains moisture in the stratum corneum by forming hydrogen bonds with water molecules, thereby providing lasting hydration and reducing trans-epidermal water loss by creating a protective barrier. Simultaneously, the Triolein moiety acts as an emollient, effectively lubricating the skin's surface, diminishing flaking, and improving its visual appearance. Additionally, Triolein can enhance the penetration of other active ingredients into the skin, while the molecule as a whole reduces surface tension to stabilize complex emulsions.

Stability
Triolein is generally stable but shows sensitivity to air and light exposure. PEG esters, while relatively stable as a class, contain ether oxygens and ester bonds that may be susceptible to enzymatic cleavage under certain conditions.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that PEGylated alkyl glycerides, including TRIOLEIN PEG-6 ESTERS, are safe for use in current cosmetic practices and concentrations, provided they are formulated to be non-irritating. This supersedes previous concentration limits. Triolein itself is considered safe for cosmetic use and holds FDA approval as an indirect food additive.
