SODIUM POLYNAPHTHALENESULFONATE
Is SODIUM POLYNAPHTHALENESULFONATE safe for seborrheic dermatitis?
There is not enough seborrheic-dermatitis-specific evidence to label Sodium Polynaphthalenesulfonate clearly helpful or harmful. It is a formula stabiliser and dispersing surfactant, not a fatty oil or treatment active.
No applicable human seb derm or ingredient-specific Malassezia study was found. Its effect depends mainly on concentration and the complete cleansing or gel system, so judge the finished product by whether it leaves inflamed skin comfortable rather than tight, itchy or red.

What is SODIUM POLYNAPHTHALENESULFONATE used for in skincare?
Sodium Polynaphthalenesulfonate is a water-soluble synthetic polymer used to keep particles or pigments evenly dispersed, help gels form and improve the flow and stability of complex formulas. It can also act as a hydrotrope or supporting cleanser ingredient rather than the main skin-active component.
