Used primarily as a detergent cleansing agent. Can be derived from coconut. It’s considered gentle and effective as typically used in cosmetics products (typically facial or body cleansers and shampoos). Despite the name similarity, sodium laureth sulfate is NOT the same as sodium lauryl sulfate. The former is a milder cleansing agent due to a higher amount and different chemical structure of the fatty alcohols required to manufacture this cleansing agent. The safety of sodium laureth sulfate has been reviewed by numerous industry experts and deemed safe as used.
