C12-15 Pareth-12

What is C12-15 Pareth-12?

C12-15 Pareth-12 is a nonionic surfactant produced by reacting a blend of synthetic C12-15 fatty alcohols with 12 molecules of ethylene oxide, creating a water-soluble compound with a hydrophobic tail and hydrophilic head. Commonly found in rinse-off cleansers, shampoos, body washes, and leave-on emulsions like lotions, it works by reducing surface tension between oil and water, allowing dirt and oils to be rinsed away effectively. As an emulsifier, it forms a protective film at the oil-water interface, preventing separation and ensuring product stability and even application. This ingredient supports the creation of lightweight, non-greasy formulas suitable for daily use across various formulations.
