Is PEG-150 a Good Ingredient?

Rated Fair: it's useful mainly as a texture builder and solubilizing aid with limited direct skin benefit, so its performance gains stay formulation-focused. Mild, concentration-dependent irritation or tackiness can also occur in sensitive users, which keeps it below Good.
