Mechanism of Action
As a surfactant, LAURETH-38 functions by reducing the interfacial tension between immiscible phases, such as oil and water. This allows it to effectively emulsify, helping to blend ingredients, cleanse by lifting dirt and oil, and solubilize hydrophobic substances into aqueous solutions.

Stability
LAURETH ingredients typically exhibit good water solubility, which tends to increase with higher ethylene oxide unit counts. Based on related ethoxylated alcohols, LAURETH-38 is inferred to be unstable and susceptible to hydrolysis in strong acidic environments. A neutral pH, such as 7.4 (as noted for Laureth-12 solutions), is generally suitable for maintaining its stability.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed LAURETH-38 and similar Laureth ingredients safe for use in cosmetics, provided they are formulated to be non-irritating. These compounds possess the potential to cause skin irritation, with effects increasing proportionally with concentration. Due to its ethoxylation process, trace amounts of 1,4-dioxane, a by-product, may be present and should be strictly controlled through purification to meet safety standards.
