PEG-6
Is PEG-6 safe for seborrheic dermatitis?
PEG-6 is generally a lower-concern ingredient for seborrheic dermatitis. It helps dissolve ingredients and hold water in a formula, and it is not an oil, free fatty acid or treatment for seb derm.
No direct human seb derm or ingredient-specific Malassezia evidence was found. PEG-6 is normally a supporting ingredient, so concentration, product type and the surrounding surfactants or preservatives matter more than the name on its own. A finished product can still sting irritated skin even when this ingredient has an accepted cosmetic role.

What is PEG-6 used for in skincare?
PEG-6 is a small, water-soluble polyethylene glycol used as a humectant and solvent. It can help keep other ingredients dissolved, improve spread and reduce moisture loss from the product itself. It is commonly found alongside water, glycerin, glycols, surfactants and preservative systems in cleansers, serums and creams.
