Ingredient

Sodium Lauryl Sulfate (SLS)

Flagged in 7

Scout's take

The most aggressive mainstream surfactant; primary skin/scalp irritant. Unusual choice for a brand marketed as 'naturally derived' -- most clean brands use coco-glucoside or decyl glucoside. Despite the 'denotes plant or mineral origin' asterisk, plant-derived SLS is chemically identical to petroleum-derived SLS in irritation potential.

More from Scout's analyses

The most aggressive mainstream surfactant; primary skin/scalp irritant. Combined with SLES creates the harshest commercial cleansing system in widespread use.
