What TEA-Dodecylbenzenesulfonate does

Cleans by lifting oil and dirt
Makes a rich, bubbly lather
Helps the wash spread and rinse evenly

TEA-Dodecylbenzenesulfonate is an anionic surfactant, a type of cleansing ingredient that loosens oil and dirt so water can carry them away. It is made by reacting dodecylbenzene sulfonic acid, a benzene ring with a 12-carbon chain attached, with triethanolamine, a mild alkaline base. The result is a salt that dissolves easily in water and builds foam quickly.

Formulators use it in shampoos and cleansers because it gives a rich lather and strong cleaning power. Its strength is also its limit. It can feel drying on skin or hair, especially with frequent use, so many formulas pair it with milder surfactants and conditioning ingredients. Rinse it off well.

Good for

Suits people who want a rich, bubbly cleanse in shampoo or body wash, and it works best when fully rinsed away.

Frequently asked questions

Is TEA-Dodecylbenzenesulfonate harsh?

It is a strong cleanser, so it can feel stripping on dry or sensitive skin and hair. Most people tolerate it well when it is rinsed away fully. If your scalp or skin feels tight after washing, a gentler surfactant or a conditioner may suit you better.

Is it the same as sodium lauryl sulfate?

They are related but not identical. Both are anionic surfactants that foam and clean well. TEA-Dodecylbenzenesulfonate uses a benzene ring in its structure, while sodium lauryl sulfate has a straight carbon chain. Both are used in shampoos and cleansers.
