DIETHYLAMINOETHYL METHACRYLATE.

Avoid CAS 105-16-8 / NAIL CONDITIONING

Diethylaminoethyl Methacrylate (DEAEMA) is a cationic, pH-responsive monomer primarily utilized as a raw material in polymer synthesis. Its polymeric form can provide film-forming and conditioning properties in cosmetic applications.

Summary

Film-forming agent Conditioning agent pH-responsive polymer

Science

Mechanism of Action

This ingredient's tertiary amine functionality renders it pH-responsive, allowing it to switch between hydrophobic and hydrophilic states. Protonation of its amine groups in acidic conditions enhances its solubilization and functional attributes.

Stability

This monomer requires a stabilizer (e.g., ~100 ppm PTZ) and should be stored under air below 35°C to prevent exothermic polymerization. Its solubility and properties are pH-responsive, with enhanced solubilization in acidic environments.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk High

The CIR Expert Panel deems it safe only when skin contact is strictly avoided, particularly in nail enhancement products, due to strong sensitization and irritancy potential. It is classified as an irritant and skin sensitizer.
