Product Description
Sodium Laureth Sulfate (SLES) is a highly effective anionic surfactant known for its excellent foaming and cleansing properties. It appears as a white to light yellow viscous paste or gel, is readily soluble in water of any hardness, and is stable across a wide pH range. SLES is non-corrosive and does not exhibit alkaline characteristics. It is compatible with anionic, non-ionic, and amphoteric surfactants, but not with cationic types. The product is hygroscopic and should be stored in sealed containers to avoid moisture absorption.
