PENTAERYTHRITYL TETRAACRYLATE.

Avoid CAS 1245638-61-2 ; 4986-89-4 / FILM FORMING

PENTAERYTHRITYL TETRAACRYLATE is a highly reactive, multifunctional acrylate monomer designed to form robust, crosslinked polymer networks. This polymerization, typically initiated by UV light or free radicals, imparts significant hardness, chemical resistance, and mechanical strength to the resulting material.

Summary

Science

Mechanism of Action

This ingredient functions by rapid polymerization, forming densely crosslinked polymer networks. Its multifunctional acrylate structure allows it to react quickly, predominantly via free-radical and UV-curing mechanisms. The resulting polymeric structure is characterized by enhanced mechanical properties, including increased hardness and resistance to chemical degradation.

Stability

Polymerization can occur slowly at room temperature and is significantly accelerated by heat, contamination, an oxygen-free environment, free radicals, peroxides, and depletion of stabilizing inhibitors. This reaction can be exothermic and difficult to control. For optimal stability, storage should be maintained below 38°C in sealed original containers, protected from physical damage, direct sunlight, and UV light. Regular monitoring of inhibitor levels (e.g., 4-methoxyphenol/MEHQ at 300-400 ppm) and dissolved oxygen content is critical.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk High

PENTAERYTHRITYL TETRAACRYLATE is categorized as a hazardous substance. It is known to cause skin irritation, serious eye damage, and allergic skin reactions (sensitization). It is identified as a weak skin sensitizer, with a potential for cross-sensitization to other acrylates and methacrylates. It is crucial to note that while Pentaerythrityl Tetraester compounds (a distinct chemical class) have been deemed safe by CIR, PENTAERYTHRITYL TETRAACRYLATE itself, an acrylate monomer, has not undergone specific CIR review.

Our Assessment

Verdict

Avoid

Due to its classification as a hazardous substance, high risk of skin irritation, serious eye damage, and strong potential for allergic skin sensitization, PENTAERYTHRITYL TETRAACRYLATE is unequivocally unsuitable for precision skincare formulations.
