DISODIUM PHOSPHATE
Is DISODIUM PHOSPHATE safe for seborrheic dermatitis?
Disodium Phosphate is not usually an ingredient that raises a specific seborrheic-dermatitis concern. It is mainly used in small amounts to help control a product's pH and stability, not to act directly on skin or treat a flare.
No direct human seb derm or ingredient-specific Malassezia evidence was found for this page. That does not prove every formula will suit you, because pH, preservatives and the rest of the product can still affect inflamed skin. Focus on how the finished product feels and stop if it repeatedly stings or increases redness.

What is DISODIUM PHOSPHATE used for in skincare?
Disodium Phosphate is an inorganic salt that formulators use mainly as a buffer. A buffer helps keep a product within its intended pH range as it is manufactured, stored and used. It may also support formula stability, but it is not included as a moisturiser or seb derm treatment.
