Polybutene is generally a lower-concern ingredient for seborrheic dermatitis. It adds gloss, binding and thickness to a formula and is not a treatment.

It is a synthetic hydrocarbon polymer rather than a fatty acid or triglyceride oil, and no applicable ingredient-specific Malassezia concern was found. A sticky or highly occlusive finished product may still feel uncomfortable for some users, so texture, cleansing and the rest of the ingredient list remain relevant.
