Sodium Laureth Sulphate (SLES) is a high-performance anionic surfactant known for its excellent cleansing, foaming, emulsifying, and wetting properties. Derived from ethoxylated lauryl alcohol, SLES is milder than SLS (Sodium Lauryl Sulfate) and is widely used in personal care products, household cleaners, and industrial formulations.
It is highly effective at removing oil, dirt, and impurities while being gentle on skin and hair, making it ideal for shampoos, body washes, hand washes, toothpaste, and facial cleansers.
