Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not specifically evaluated this exact copolymer. However, for structurally related trimellitic anhydride copolymers, the CIR determined that data were insufficient to establish safety for cosmetic applications beyond nail products. Furthermore, EWG highlights that this ingredient has not undergone safety assessment by an industry panel and raises concerns regarding potential contamination with Ethylene Oxide and 1,4-Dioxane, which are common byproducts of ethoxylation. Its inclusion in EWG VERIFIED products is restricted without adequate scientific substantiation.

Verdict
Due to the absence of specific safety assessments for skin applications, insufficient data for non-nail cosmetic use, and potential contamination concerns, this ingredient's suitability for precision skincare formulations is highly questionable.
