Sodium Laureth Sulfate
Excellent Cleaning Efficiency: Sodium Laureth Sulfate (SLES) significantly lowers the surface tension of water, enabling superior removal of dirt and contaminants.
Rich and Stable Foaming: Due to its distinct molecular configuration, SLES generates abundant and stable foam, making it a preferred choice in personal care and cleaning formulations.
Hard Water Tolerance: It maintains high effectiveness in hard water conditions, ensuring reliable performance across various water qualities.
Broad Emulsifying Capacity: With its efficient emulsifying properties, SLES is widely used in diverse products including cosmetics, shampoos, soaps, and detergents.
Sodium Laureth Sulfate (CAS #3088-31-1) is an anionic surfactant valued for its outstanding cleaning, emulsifying, foaming, and hard water resistance properties. Its molecular architecture incorporates hydrophobic long-chain alkyl groups, hydrophilic polyoxyethylene ether chains, and sodium sulfate ester groups. This structure enables the compound to effectively reduce surface tension in aqueous solutions, promote micelle formation, and deliver high performance in cleansing, emulsification, and foam generation.

Sodium Lauryl Polyether Sulfate (SLES) is an anionic surfactant widely employed in household and personal care products, industrial processes, and pharmaceutical formulations. It acts as a key cleansing and foaming agent in products such as shampoos, body washes, and detergents. Within industrial settings—including textiles, petroleum, and paper manufacturing—SLES functions as a leveling agent, an additive in drilling fluids, an emulsifier, and in other specialized roles.
