Laureth-5
What is Laureth-5?
Laureth-5 is a polyoxyethylene ether derived from lauryl alcohol, a saturated C12 fatty alcohol often obtained from coconut or palm sources, ethoxylated with five ethylene oxide units to enhance solubility and functionality. This synthetic non-ionic compound belongs to the laureth family of surfactants widely incorporated into rinse-off products such as shampoos, shower gels, and facial cleansers, as well as leave-on items like moisturizers and makeup removers. It operates by lowering surface tension at interfaces, allowing water to mix with oils and soils for thorough removal during cleansing. In emulsified systems, Laureth-5 creates a protective barrier around droplets, ensuring product stability, uniform texture, and even distribution. Its balanced hydrophilic-lipophilic properties promote good rinsability and mild interaction with skin lipids, supporting formula performance without excessive disruption.
