Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not provided a specific safety assessment for NORBORNANEDIAMINE/RESORCINOL DIGLYCIDYL ETHER CROSSPOLYMER. While the safety profile of a crosspolymer can differ significantly from its individual monomers, one precursor, Diglycidyl Resorcinol Ether, is classified by the European Chemicals Agency (ECHA) and PubChem as a potential carcinogen (Carc. 1B or 2), an irritant to skin and eyes, and a potential sensitizer that may cause allergic skin reactions and genetic defects. Despite these serious concerns regarding the monomer, the Environmental Working Group (EWG) Skin Deep database rates the crosspolymer itself with 'LOW' concern for cancer, allergies & immunotoxicity, and developmental toxicity. The Scientific Committee on Consumer Safety (SCCS) has not issued an opinion on this specific crosspolymer.

Verdict
Due to the severe safety concerns associated with a key monomer and the absence of comprehensive safety evaluations for the crosspolymer by established expert panels, its inclusion in precision skincare formulations is highly questionable.
