Science
Mechanism of Action
As a polymer, Polyethylene Naphthalate likely functions in skincare by forming a physical film, creating a protective barrier on the skin's surface. Furthermore, it possesses intrinsic UV absorption capabilities up to approximately 383nm, a material property that could theoretically enhance a product's overall UV protection or safeguard the formulation itself from photodegradation.

Stability
Polyethylene Naphthalate exhibits notable resistance to hydrolysis, particularly under alkaline or very hot aqueous conditions, contributing to its overall stability in various formulations.
Safety
Safety Profile
No specific Cosmetic Ingredient Review (CIR) or Scientific Committee on Consumer Safety (SCCS) assessment has been conducted for Polyethylene Naphthalate as a cosmetic ingredient. Industrial safety data indicates that direct skin contact is not expected to result in significant irritation, and no critical hazards are noted for the material itself. It is also approved for use in food contact articles under US FDA regulations.
