Diethanolamine

What Diethanolamine is & what it does

Diethanolamine, often abbreviated DEA, is an organic compound used in cosmetics mainly as a pH adjuster and as a building block for surfactants and emulsifiers. It helps neutralize acidic ingredients and stabilize formulas. Free DEA has drawn scrutiny over impurity concerns, so its use has declined and it is typically limited to low levels under modern formulation standards. It is used as a functional processing aid rather than an active skincare ingredient.
