Frequently asked questions

Is methosulfate a sulfate like SLS?
No, methosulfate is not the same as sodium lauryl sulfate (SLS) or sodium laureth sulfate (SLES). While both are surfactants, methosulfate is typically used as a conditioning agent and is generally considered milder than the cleansing sulfates.
