DITRIMETHYLOLPROPANE TRIACRYLATE.

Avoid / FILM FORMING

DITRIMETHYLOLPROPANE TRIACRYLATE is a trifunctional acrylate ester monomer primarily known for its ability to polymerize under UV or electron beam irradiation, forming hard, resistant films. However, its comprehensive safety profile, including carcinogenic potential and high sensitization risk, renders it unsuitable for precision skincare formulations.

Summary

Filmforming Cross-linking Agent Reactive Diluent

Science

Mechanism of Action

This ingredient functions as a reactive diluent, film-former, and cross-linking agent. Upon exposure to UV light or electron beam irradiation, it undergoes polymerization, creating a robust, cured film. This process imparts desirable characteristics such as enhanced hardness, strong adhesion, and increased resistance to the final material.

Stability

DITRIMETHYLOLPROPANE TRIACRYLATE exhibits chemical stability under standard ambient conditions. However, it is hygroscopic, sensitive to light, and prone to spontaneous polymerization when exposed to direct sunlight and heat. Stability can be enhanced with the addition of monomethyl ester of hydroquinone.

Safety Profile

CIR Status
Not reviewed
Sensitization risk High

Extensive safety concerns surround DITRIMETHYLOLPROPANE TRIACRYLATE. It is classified by the International Agency for Research on Cancer (IARC) as Group 2B, indicating it is possibly carcinogenic to humans, and is listed under California's Proposition 65 as 'Known to cause cancer'. As of November 2023, mixtures containing 1% or more by weight are classified as carcinogen category 2 (H351). Consequently, its use in cosmetics is strictly prohibited by EU Cosmetics Regulation. Furthermore, it is a potent sensitizer and irritant; studies in guinea pigs demonstrated mild to moderate skin sensitization at 0.5% concentration, with an intradermal sensitivity concentration for 50% of subjects at 5.4%. It is explicitly known to cause skin irritation (H315), serious eye irritation (H319), and may cause an allergic skin reaction (H317). Sensitivity has also been reported in occupational settings.
