Science
Mechanism of Action
This ingredient functions as an emollient, actively contributing to skin suppleness and a smooth texture. It creates a breathable film on the skin's surface, which is vital for maintaining the skin barrier, reducing transepidermal water loss, and offering protection against environmental factors. Additionally, it acts as a plasticizer, aids in the uniform dispersion and dissolution of pigments, and can increase the viscosity of emulsion-based formulations, imparting lubricity and a cushioning feel.

Stability
Triethylhexyl Trimellitate maintains stability under recommended storage conditions, specifically at room temperature, in tightly sealed containers, and protected from direct sunlight or excessive heat. It exhibits heat tolerance up to 80°C. Hydrolysis is an identified environmental degradation pathway, with decreased stability observed at higher pH levels; for instance, a related trioctyl trimellitate showed half-lives of 120 days at pH 7 and 12 days at pH 8.
Safety
Safety Profile
The CIR Expert Panel has determined that trialkyl trimellitates, including Triethylhexyl Trimellitate, are safe under current conditions of use and concentration, provided formulations are non-irritating. Although some sources suggest it as a potential endocrine disrupting compound, the CIR's in vitro tests indicated no affinity for ERα and no estrogenic activity. Its utilization in cosmetic formulations is supported by FDA VCRP data.
