Science
Mechanism of Action
This copolymer forms a continuous, ultra-thin protective film on the skin's surface, acting as a barrier against environmental aggressors such as chemical exposure, UV radiation, and pollution. Additionally, it enhances viscosity in non-aqueous systems, stabilizing formulations and contributing to a smooth, even texture.

Stability
The copolymer maintains stability under normal storage conditions, demonstrating compatibility with a wide range of cosmetic products due to its generally neutral pH. Protection from excessive heat and moisture is recommended.
Safety
Safety Profile
The CIR Expert Panel deemed this ingredient safe for use in nail product formulations, specifically at concentrations up to 12%. However, there is insufficient data to definitively determine its safety for inclusion in other cosmetic formulation types. While recognized as a polymer of low concern for cosmetic nail products by NICNAS, a significant number of contact allergy cases resulting in dermatitis have been documented.
