Laureth-21
Laureth-21 is a synthetic polymer derived from lauryl alcohol and ethylene oxide, functioning as a surfactant and emulsifier. It helps to cleanse the skin and hair by reducing surface tension, allowing oil and dirt to be washed away. It also aids in stabilizing formulations by blending immiscible ingredients.
