Sodium Laureth Sulfate (SLES) is a widely used surfactant and detergent in the cosmetics, personal care, and cleaning product industries. It is valued for its exceptional foaming and cleaning properties, making it a common ingredient in shampoos, body washes, toothpaste, and household cleaning agents. SLES effectively removes dirt, oils, and impurities, creating lathering and cleansing products that consumers often associate with a thorough and refreshing clean. Despite its effectiveness, there have been concerns about its potential to irritate sensitive skin, prompting some manufacturers to seek milder alternatives in their formulations.
