Science
Mechanism of Action
As an emulsifying agent, Trideceth-18 facilitates the stable blending of disparate oil and water phases within a formulation, preventing separation and maintaining product integrity. Concurrently, its surfactant properties enable it to lower surface tension, enhancing the spreadability of products and contributing to the effective removal of impurities from skin and hair.

Stability
While no specific optimal pH range for Trideceth-18 stability has been identified, its nature as a polyethylene glycol (PEG) derivative suggests general PEG stability considerations may apply, though explicit data for this specific compound is not available.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has determined Trideceth ingredients, including Trideceth-18, to be safe when formulated to be non-irritating. Improper formulation can lead to skin irritation. Manufacturers must also control for residual 1,4-dioxane, a potential by-product of the ethoxylation process, through rigorous purification steps. The FDA permits its use as an indirect food additive, such as defoaming agents.
