Science
Mechanism of Action
Upon application, this crosspolymer forms an occlusive yet flexible film over the skin, hair, or nails. This film functions as a protective barrier, contributing to product longevity, wear resistance, and potentially enhancing the delivery or retention of other active ingredients on the surface.

Safety Profile
While the Cosmetic Ingredient Review (CIR) has generally deemed categories of crosspolymers safe, there is no specific CIR assessment for this particular diisocyanate crosspolymer. There is a potential for irritation from residual isocyanate monomers or degradation products, and prolonged exposure may lead to sensitization. Despite these specific concerns, INCI Beauty reports 'No penalty' across all categories for this ingredient.
