Science
Mechanism of Action
This compound functions by polymerizing to form homopolymers or copolymers, which then create a thin, cohesive film on surfaces. In topical applications, this film contributes to a hydrophobic barrier, improving product adherence and resilience, while also offering flexible and conformable properties.

Stability
Ethylhexyl Methacrylate exhibits high hydrolytic stability, showing negligible degradation at neutral pH (7.4) and a low hydrolysis rate under mildly alkaline conditions (pH 10). Acid-catalyzed hydrolysis is generally slower. However, it is sensitive to heat and light, which can induce polymerization. To prevent this, storage must always be under air (oxygen is vital for stabilizer function) and at temperatures not exceeding 35 °C.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed Ethylhexyl Methacrylate safe for use in nail enhancement products, provided that direct skin contact is strictly avoided due to its recognized sensitizing potential. This determination was reconfirmed in 2021-2022. There is no established maximum concentration for direct skin application in cosmetics, as contact is explicitly advised against. The FDA permits its use as an indirect food additive in coatings.
