PEG-4 TRIMETHYLOLPROPANE TRIACRYLATE.

Avoid CAS 28961-43-5 / FILM FORMING

PEG-4 Trimethylolpropane Triacrylate is a synthetic polymer functioning primarily as a film-forming and binding agent. It is designed to create a continuous, adhesive film on surfaces, often leveraged in industrial and cosmetic formulations requiring robust adhesion and a protective layer.

Summary

Film-forming Binding

Science

Mechanism of Action

This ingredient forms a continuous, stable film upon application to skin, hair, or nails, acting as a structural binder. Its acrylate chemistry facilitates cross-linking, a mechanism crucial for its performance in systems requiring durable film integrity, such as UV-curable coatings.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Moderate

While PEG-4 itself was deemed safe by the CIR Expert Panel (up to 20% in manicure products), PEG-4 Trimethylolpropane Triacrylate has not undergone a dedicated CIR review. A critical safety concern stems from its un-PEGylated analog, Trimethylolpropane Triacrylate (TMPTA), which is classified as a Class 2 carcinogen by the European Chemicals Agency (ECHA) and has been prohibited in EU cosmetic products since December 1, 2023. Additionally, PEG compounds in general are advised against use on compromised or damaged skin due to the potential for enhanced dermal penetration and subsequent systemic exposure.

Our Assessment

Verdict

Avoid

Due to its unreviewed safety status, moderate irritancy, and the classification of its un-PEGylated counterpart as a Class 2 carcinogen prohibited in EU cosmetics, PEG-4 Trimethylolpropane Triacrylate should be avoided in precision skincare formulations.
