Science
Mechanism of Action
This ingredient functions by significantly reducing the surface tension of cosmetic formulations, which facilitates the even application and spread of products. As an emulsifier, it plays a critical role in stabilizing immiscible liquids like oil and water, ensuring homogeneous mixtures. Its cleansing action stems from its ability to interact with skin impurities, aiding their removal and contributing to a clean epidermal surface.

The Formula
Formulation
Stability
Formulations containing TEA-PALMITATE are typically alkaline, with the Triethanolamine base exhibiting a pH range of 10-12, which can contribute to overall product stability. It is critically important to formulate without N-nitrosating agents to prevent the formation of potentially harmful nitrosamines.

Safety
Safety Profile
The CIR Expert Panel considers TEA-PALMITATE safe for cosmetic use under specific conditions, primarily when formulated to be non-irritating. For leave-on products, concentrations must not exceed 5%. Formulators must avoid combining this ingredient with N-nitrosating agents to prevent the generation of potentially carcinogenic nitrosamines. The SCCS also approves its use with similar restrictions, and it holds FDA approval as an indirect food additive.
