Sodium Acetate is generally a lower-concern ingredient for seborrheic dermatitis. It is usually present in a supporting amount to help manage product pH or fragrance, rather than acting as a treatment or rich skin-conditioning lipid.

No direct human seb derm or exact-name Malassezia evidence was found. The measured pH and overall formula are more relevant than the salt by itself. Stop using a product that repeatedly causes stinging, tightness or redness on inflamed skin.
