TETRASODIUM ETIDRONATE
Is TETRASODIUM ETIDRONATE safe for seborrheic dermatitis?
Tetrasodium Etidronate is generally a lower-concern ingredient for seborrheic dermatitis in a properly formulated cosmetic. It mainly protects the formula from metal-related changes and is not intended to treat the skin condition.
No applicable evidence found for this page shows that Tetrasodium Etidronate feeds Malassezia or improves a flare. Its presence usually says more about product stability than skin activity. Judge the complete formula and stop if it repeatedly causes burning, itching or redness.

What is TETRASODIUM ETIDRONATE used for in skincare?
Tetrasodium Etidronate is a chelating agent that binds trace metal ions. Formulators use it to help preserve colour, odour, clarity and performance, especially in soaps and water-based products. It works behind the scenes as a stabiliser and should not be confused with an exfoliant, antifungal active or treatment ingredient.
