Sodium Lauryl Ether Sulfate (SLES) is a widely used anionic surfactant known for its excellent foaming and cleansing properties. It is typically derived from ethoxylated lauryl alcohol and is available as a clear to slightly yellowish liquid. SLES is commonly used in personal care products such as shampoos, body washes, and facial cleansers, as well as in household cleaning agents and industrial detergents. Its ability to emulsify oils, suspend dirt, and generate rich lather makes it a key ingredient in formulations requiring effective surface activity. SLES is favored for being milder than its counterpart, sodium lauryl sulfate (SLS), and is often used in applications where skin sensitivity is a concern.
