What Cocamidopropyl Betaine does

Lifts oil and dirt from skin and hair
Builds a soft, creamy foam
Thickens liquid cleansers
Softens harsher cleansing ingredients

Cocamidopropyl Betaine is made from fatty acids taken from coconut oil, which are reacted with a second compound containing nitrogen to form a surfactant. Surfactants are cleansing ingredients that help water mix with oil and dirt. This one is called amphoteric, meaning it can carry a positive or negative charge depending on the pH of the formula, so it works across a wide range of product types.

Formulators mostly use it as a partner to stronger cleansers. Harsher ingredients such as sodium lauryl sulfate are often paired with it, because it softens their drying effect and adds a thick, creamy foam. It also thickens liquid formulas. In use, it feels slick and rinses clean for most people.

Good for

People looking for gentle shampoos, body washes and cleansers, including those with dry or sensitive skin who want a softer lather.

Be careful if

Nothing in particular for most skin types.

Frequently asked questions

Is Cocamidopropyl Betaine safe for sensitive skin?

It is generally well tolerated and is often used in gentle cleansers. Still, a small number of people react to it, so if your skin is very sensitive, try a small patch on your arm first and see how it feels over a day or two.

Is Cocamidopropyl Betaine the same as sulfates?

No. Sulfates such as sodium lauryl sulfate belong to a different chemical family. This ingredient is a betaine, and it is often paired with sulfates to soften them and build a richer foam. Check the full list if you want to avoid either.
