What Cocamidopropyl Hydroxysultaine does

Cleans oil and dirt from skin and hair
Creates a soft, stable foam
Works across a wide pH range

Cocamidopropyl Hydroxysultaine is made from fatty acids taken from coconut oil, joined to an amine-based chain and given a sulfonate group. It is an amphoteric surfactant, a cleansing agent whose molecule carries both a positive and a negative charge. The name hints at its origin: 'cocamido' points to coconut.

Formulators use it alongside other cleansers. It helps lift oil and dirt, builds a dense, creamy foam, and softens the feel of a wash. It works across a wide range of pH levels, which gives makers flexibility. In a rinse, it tends to feel smooth rather than squeaky.

Good for

Anyone looking for an everyday face wash, body wash or shampoo that cleans well without a harsh feel.

Frequently asked questions

Is Cocamidopropyl Hydroxysultaine gentle on sensitive skin?

It is generally considered a gentle cleansing ingredient. Like any surfactant, how a wash feels depends on the whole formula and your own skin. If a product stings or feels tight, rinse well, stop using it, and check with a dermatologist.

Is it a sulfate?

No. Sulfates such as sodium lauryl sulfate have a different structure. This ingredient contains a sulfonate group, which is a different sulfur-based group from the sulfate in those cleansers. It is often chosen as a milder alternative to sulfate cleansers.
