Science
Mechanism of Action
As a crosslinked polymer, Polyurea Crosspolymer-2 functions by forming a stable, non-occlusive film on the skin's surface, which can aid in product longevity and a smooth finish. Its polymeric structure also allows it to modify the rheological properties of formulations, acting as an absorbent, emulsion stabilizer, suspending agent, and viscosity enhancer.

Stability
Crosslinked polymers, including Polyurea Crosspolymer-2, typically exhibit superior chemical stability and reduced solubility compared to their non-crosslinked counterparts. Polyurea systems are also generally more resistant to high pH (alkaline) conditions than polyurethane systems.
Safety
Safety Profile
The CIR Expert Panel concluded that related crosslinked alkyl acrylates are safe under current practices, provided they are not polymerized in benzene. For ingredients polymerized using benzene, safety data were insufficient. A specific assessment by the Australian Industrial Chemicals Introduction Scheme (AICIS) determined Polyurea Crosspolymer-2 to be non-irritating to rabbit skin (OECD TG 404) and eyes (OECD TG 405), and demonstrated low in-vitro phototoxicity. Given its high molecular weight, it is not anticipated to permeate biological membranes or bioaccumulate.
