Science
Mechanism of Action
The copolymer forms an imperceptible, continuous film upon application, which adheres to the skin's surface. This film acts as a physical barrier, contributing to product longevity, enhancing makeup durability, and improving overall spreadability. It also provides a degree of protection, limiting potential damage from environmental factors such as UV rays, chemicals, and pollution.

The Formula
Formulation
Stability
The precursor monomer, 2-ethylhexyl acrylate, requires storage in an oxygenated environment below 35°C to inhibit spontaneous polymerization. During formulation, the copolymer can be effectively incorporated into the hot oil phase or dispersed with solvents such as glycerin, propylene glycol, alcohol, or neutralized hot water. Slow sifting with robust agitation is recommended for optimal mixing.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Panel has deemed Ethylhexyl Acrylate/Methyl Methacrylate Copolymer, among other acrylate copolymers, safe for use in cosmetic applications, provided the final formulation is non-irritating. It is important to note the potential presence of residual monomers, including 2-ethylhexyl acrylate, methyl methacrylate, methacrylic acid, and acrylic acid, which necessitate careful formulation practices.
