PEG-8
Is PEG-8 safe for seborrheic dermatitis?
PEG-8 is generally a lower-concern ingredient for seborrheic dermatitis in a properly formulated cosmetic. It helps hold water and dissolve ingredients. It is not an active intended to treat a flare.
No applicable evidence found for this page shows that PEG-8 feeds Malassezia. PEG-8 on its own is also different from PEG ingredients attached to fatty acids or oils, so the names should not be treated as interchangeable. Judge the complete formula and stop if irritation repeatedly increases.

What is PEG-8 used for in skincare?
PEG-8 is a small polyethylene glycol used as a humectant and solvent. It helps water-based ingredients remain distributed and can improve moisture retention or product texture. Its formulation role is distinct from fatty-acid PEG esters that have longer ingredient names.
