METHACRYLOYLOXYETHYLTRIMONIUM CHLORIDE.

Questionable / NOT REPORTED

METHACRYLOYLOXYETHYLTRIMONIUM CHLORIDE is a cationic monomer primarily utilized as a building block for polymers that impart conditioning benefits to skin and hair. Its inherent positive charge allows it to effectively bind to negatively charged surfaces, contributing to film-forming and antistatic properties in cosmetic formulations.

Science

Mechanism of Action

Possessing a quaternary ammonium structure, this ingredient carries a permanent cationic charge, enabling strong electrostatic adsorption to negatively charged biological surfaces such as keratin in the skin. This mechanism is crucial for synthesizing conditioning polymers that enhance skin softness and smoothness, while also functioning as a surface-active agent.

Not reviewed
Sensitization risk Moderate

Direct safety assessments for METHACRYLOYLOXYETHYLTRIMONIUM CHLORIDE by CIR or SCCS are not available. However, a 72% aqueous solution of this ingredient carries hazard statements indicating it can cause skin irritation (H315) and serious eye irritation (H319). For related quaternary ammonium compounds, such as Cetrimonium Chloride, the SCCS has established concentration limits, for instance, up to 1.0% in leave-on hair products and 0.5% in leave-on facial creams.

Verdict

Questionable

While METHACRYLOYLOXYETHYLTRIMONIUM CHLORIDE is an effective monomer for creating beneficial conditioning polymers, the raw ingredient itself carries significant irritation warnings and lacks direct, specific safety and efficacy data for topical skin application, necessitating cautious formulation.
