Comedogenic Rating

This ingredient is not typically evaluated for comedogenicity, and no standardized rating is available.

Generally regarded as low toxicity once polymerized, but film-formers can cause dryness or mild irritation in sensitive areas. Avoid direct eye contact and discontinue use if irritation occurs.

Is Bis(Glycidoxyphenyl)Propane/Bisaminomethylnorbornane Copolymer a Good Ingredient?

It provides film formation and wear improvement, but documented skin benefits are modest and performance depends on the formulation, which keeps it at Fair. Minor irritation is possible, particularly around the eyes.
