Laureth-12

What is Laureth-12?

Laureth-12 is a synthetic polyoxyethylene ether derived from lauryl alcohol, typically sourced from coconut or palm kernel oils, reacted with 12 moles of ethylene oxide. This process creates a water-soluble, non-ionic surfactant commonly used in rinse-off products like shampoos, body washes, and facial cleansers, as well as leave-on formulations such as lotions and creams. It functions by reducing surface tension, allowing better spreading and wetting of surfaces, while enabling the formation of micelles for effective dirt and oil removal during cleansing. As an emulsifier, it stabilizes oil-in-water emulsions by creating a protective film at the interface, preventing phase separation and ensuring smooth, consistent product textures. Its higher ethoxylation level contributes to milder performance compared to shorter-chain laureths, making it suitable for everyday personal care items.
