Science
Mechanism of Action
As an anionic surfactant, TEA-Laureth Sulfate effectively cleanses the skin by lowering surface tension, allowing it to emulsify and lift away oils, impurities, and pollutants. Its hydrophilic ethoxylate groups facilitate interaction with water, while the lipophilic chain binds to oily residues, enabling their easy rinse-off. This action results in thorough cleansing and rich lather formation.

Stability
TEA-Laureth Sulfate exhibits stability across alkaline, weak acid, and hard water conditions. However, it is susceptible to hydrolysis and instability when exposed to strong acidic environments.
Conflicts
- strong acids
- N-nitrosating agents
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel deemed TEA-Laureth Sulfate safe for use under specific conditions: formulations must be non-irritating, and free diethanolamine levels must not exceed current industry practices. Crucially, it should not be incorporated into products where N-nitroso compounds could potentially form, as the presence of Triethanolamine (TEA) can facilitate N-nitrosamine generation if N-nitrosating agents are present.
