Sodium Coco-Sulfate

Sodium Coco-Sulfate (SCS) is an anionic cleanser made by sulfating coconut-derived fatty alcohols and neutralizing them into a sodium salt. It's a strong and bubbly cleanser and closely realted to SLS.

This ingredient works by grabbing onto oil, dirt, and grime so they can be rinsed away. It also helps add foam for a big-lather feel.

Like other members of the alkyl sulfate family, these surfactants can be drying or irritating. This is especially true if your skin barrier is already stressed, the product is very concentrated, or if you leave the ingredient on for too long.

One research paper comparing SCS vs SLS found SCS may score a bit more on the "milder" side for irritation measures, but it still interacts strongly with skin lipids which can cause barrier disruption.

SCS tends to be the best in rinse-off products.
