Science
Mechanism of Action
This ingredient functions by reducing the surface tension of water, allowing for better spreading of detergents and facilitating the removal of impurities from skin and hair. As a foam booster, it enhances the aesthetic and functional quality of lather. Its emulsifying properties help maintain the stability of oil-in-water mixtures, preventing separation over time. It also contributes to product opacity and imparts conditioning benefits to hair.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel deemed diethanolamides, including Tallowamide DEA, safe for use under specific conditions: formulations must be non-irritating, and free Diethanolamine (DEA) levels must not exceed established safe limits. Usage in cosmetic products capable of forming N-nitroso compounds should be avoided. While related diethanolamides are used up to 50% in cosmetics, typical concentrations range from 1-25%. The EU Cosmetics Directive also imposes restrictions on its use.
