Mechanism of Action
As a non-ionic oil-in-water (O/W) emulsifier and surfactant, Trideceth-3 functions by presenting molecules with both lipophilic (oil-attracting) and hydrophilic (water-attracting) characteristics. This amphiphilic structure effectively reduces the interfacial tension between oil and water, facilitating the formation of stable, finely dispersed emulsions and aiding in the solubilization or dispersion of substances that typically do not mix. It is chemically derived from the ethoxylation of tridecyl alcohol.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed Trideceth ingredients, including Trideceth-3, safe for use in cosmetic products when formulated to be non-irritating. Extensive safety assessments, including developmental, reproductive toxicity, and mutagenicity studies, yielded negative results. Trace amounts of 1,4-dioxane, a byproduct of the ethoxylation process, should be diligently controlled through purification. Furthermore, the FDA recognizes Trideceth ingredients as Generally Recognized as Safe (GRAS) for certain food additive applications.
