Science
Mechanism of Action
This ingredient functions by significantly lowering the surface tension between immiscible oil and water phases, thereby facilitating the creation and maintenance of stable emulsions, particularly those where water is dispersed within oil. As a PEG derivative, it possesses humectant properties, potentially enhancing skin hydration by forming hydrogen bonds with water molecules, which can support the skin's natural barrier and mitigate transepidermal water loss. Furthermore, it acts as a solubilizer, enabling the integration of oil-soluble compounds into aqueous solutions.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed sorbitan esters, including PEG-12 Sorbitan Trioleate, safe for use in cosmetics, a conclusion reaffirmed in 1985 and 2002. For the broader category of PEG Sorbitan/Sorbitol Fatty Acid Esters, the CIR Panel specifies safe use up to a maximum concentration of 25%, with the important caveat that they should not be applied to compromised or damaged skin. Related ingredients like PEG-2 Sorbitan Trioleate and PEG-20 Sorbitan Trioleate (Polysorbate 85) are recognized as safe by the FDA for certain food applications.
