Is Sodium Laureth Sulfate safe?

Sodium Laureth Sulfate carries moderate concerns worth knowing about (irritation).

In plain language

The gentler cousin of SLS used in most mainstream shampoos and washes. Its manufacturing can leave trace 1,4-dioxane, which reputable makers strip out — an issue of quality control rather than the ingredient itself.
