Product Application of Sodium lauryl ether sulfate CAS#68585-34-2
SLES（CAS#68585-34-2）is a widely used petroleum‑derived ingredient in cosmetic formulations. It delivers rich foaming action to lift and remove oils and residues from hair. Shampoos containing SLES lather quickly during use; SLES‑free formulas produce minimal or no foam. SLES is safe for general use and provides highly effective cleansing compared to alternative surfactants. However, it may be harsh for some hair types and could cause scalp irritation with prolonged frequent use.
