Science
Mechanism of Action
As a polyethylene glycol (PEG) ether, Laureth-6 primarily functions by reducing the surface tension of liquids, which effectively aids in dislodging and removing dirt and oils from the skin. Additionally, it acts as an emulsifier to create stable blends of oil and water, and as a solubilizer, enhancing the dispersion of oil-soluble ingredients in aqueous solutions.

Stability
As a non-ionic surfactant, Laureth-6 generally exhibits robust stability across various formulations. While related Laureth-6 Carboxylic Acid shows pH-dependent ionic behavior, Laureth-6 itself remains non-ionic.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) panel has deemed Laureth-6 safe for use in cosmetics, provided formulations are non-irritating. However, significant concerns exist regarding potential contamination from toxic impurities, specifically Ethylene Oxide and 1,4-Dioxane, which are byproducts of the ethoxylation process.
