PEG-12
Is PEG-12 safe for seborrheic dermatitis?
PEG-12 is generally a lower-concern ingredient for seborrheic dermatitis. It acts mainly as a water-soluble humectant, solvent or texture helper and is not a fatty oil or treatment for the condition.
No direct human seb derm or ingredient-specific Malassezia evidence was found. PEG-12 is usually present to make the complete formula work and feel better, so the product's other ingredients and final format are more useful than this name alone. Even a technically suitable formula should be stopped if it repeatedly stings inflamed skin.

What is PEG-12 used for in skincare?
