The Formula
Formulation
Stability
Triethyl Phosphate exhibits high stability at ambient temperatures. In aqueous formulations, it remains stable at room temperature, though slow hydrolysis can occur at elevated temperatures. For optimal stability in water-based systems, pH monitoring is advisable. It maintains stability up to 180°C, but sustained exposure above this temperature should be avoided.
Conflicts
- Strong reducing agents (e.g., hydrides)
- Oxidizing agents (potential release of toxic phosphorus oxides)
- Prolonged exposure exceeding 180°C
Safety
Safety Profile
No dedicated safety assessment for cosmetic application to skin has been conducted by regulatory bodies such as CIR or SCCS. While recognized by the FDA as a food contact substance and an inert pesticide ingredient, Triethyl Phosphate is known to severely irritate the skin, eyes, and mucous membranes. It is classified as a moderate health hazard, with particular concern for skin and eye contact, and the potential for adverse effects from prolonged exposure.

Verdict
Due to its severe irritant potential and lack of demonstrated direct skin benefits as an active cosmetic ingredient, Triethyl Phosphate is strongly advised against for skincare formulations.
