METHOXYETHYL ACRYLATE.

Avoid CAS 3121-61-7 / FILM FORMING

Methoxyethyl Acrylate is a reactive monomer primarily utilized in industrial polymer synthesis. In cosmetic applications, it serves as a foundational building block for various acrylate copolymers, contributing to their film-forming capabilities.

Science

As a monomer, Methoxyethyl Acrylate undergoes polymerization to create larger copolymer structures. These resulting copolymers form a thin, protective film on the skin or hair, which can provide effects such as improved adhesion, hold, or occlusion.

Safety

CIR Status
Insufficient data
Sensitization risk High

The CIR Expert Panel has not evaluated Methoxyethyl Acrylate as a standalone cosmetic ingredient; however, the acrylate copolymers derived from it are deemed safe when formulated with very low residual monomer concentrations, typically below 20 ppm. As a monomer, GHS classifications highlight it as a hazardous substance, indicating flammability, toxicity upon ingestion or inhalation, severe skin and eye damage, allergic sensitization potential, and suspicion of genetic defects or harm to fertility/unborn child. Regulatory bodies like the FDA have historically expressed concerns and taken action against the use of similar liquid acrylate monomers in consumer products due to severe adverse reactions.

Our Assessment

Avoid

Due to severe hazard classifications including high irritancy and reproductive toxicity risks, direct use of Methoxyethyl Acrylate in skincare formulations is strictly contraindicated.
