What it does

Sodium sulfate is a simple mineral salt. Small amounts thicken surfactant blends and it bulks out bath salts and powders. CosIng lists it as bulking and viscosity controlling.

It is a mineral salt, not a cleansing sulfate, so the sulfate-free check ignores it. It affects none of the six checks.
