Sodium Lauroyl Methyl Isethionate is NOT the same as (SLS) Sodium laureth sulfate (which is considered harsh). So what is it?
Sodium Lauroyl Methyl Isethionate is a supportive ingredient and is a "co-surfactant". Surfactants are needed in products to emulsify oils, create lather and suspend all that nasty stuff we want to wash away. It's very mild and gentle ingredient and because of its BIG molecular size, it doesn't penetrate the skin. Bottom line, it's very safe, non-toxic, doesn't irritate and is biodegradable.
