SODIUM PHOSPHATE
Is SODIUM PHOSPHATE safe for seborrheic dermatitis?
Sodium Phosphate is not automatically unsafe for seborrheic dermatitis, but it is not a proven treatment either. In skincare it is mainly a buffer that helps keep formula pH stable, even when a database also lists broader cosmetic functions.
No applicable exact-ingredient human seb derm or Malassezia evidence was found. The final pH and the rest of the formula determine comfort, so do not interpret an anti-seborrheic function label as evidence that Sodium Phosphate alone will improve a flare.

What is SODIUM PHOSPHATE used for in skincare?
Sodium Phosphate is an inorganic salt used mainly to buffer and stabilise the pH of water-based formulas. A stable pH can help preservatives and other ingredients work as intended, but the salt itself is usually a supporting formulation ingredient rather than the reason a product is effective.
