C12-15 Pareth-2

What is C12-15 Pareth-2?

C12-15 Pareth-2 is a synthetic nonionic surfactant derived from a blend of linear alcohols with 12 to 15 carbon atoms, ethoxylated with an average of two ethylene oxide units. This chemical modification enhances its water solubility and ability to interact with both oils and water. Commonly found in cleansers, shampoos, body washes, and emulsion-based products like lotions, it works by lowering surface tension at interfaces. This action disperses oils and dirt during cleansing and forms stable films that prevent separation of oil and water phases in formulations, resulting in smooth textures and effective product performance without harshness.
