Product Description
Sodium Laureth Sulfate (SLES) is a high-performaleic-anhydride.html">mance anionic surfactant. It offers outstanding detergency, emulsification, foaming capacity, and hard-water resistance. Its molecular structure combines lipophilic alkyl chains, hydrophilic polyoxyethylene ether segments, and sodium sulfate ester groups, allowing it to effectively lower water surface tension, form stable micelles, and deliver strong cleaning, emulsifying, and foaming effects.
