Comparison of Pentasodium Pentetate (DTPA-5Na) 40% vs 50% Concentration

The main difference between Pentasodium Pentetate (DTPA-5Na, 40%) and Pentasodium Pentetate (DTPA-5Na, 50%) is the concentration of the active ingredient.

• Pentasodium Pentetate (DTPA-5Na, 40%): Contains 40% active matter in an aqueous solution.
• Pentasodium Pentetate (DTPA-5Na, 50%): Contains 50% active matter in an aqueous solution.

Both products share the same INCI Name (Pentasodium Pentetate) and serve the same function as a chelating agent, which helps stabilize formulations by binding with metal ions. They are commonly used in permanent hair dye products and other cosmetic formulations that require a strong chelator.

There are no other different functional ingredients between the two; the choice between them depends on your desired concentration in the final formulation and ease of use. If you switch from the 40% version to the 50% version, you would need to adjust the dosage downward to maintain the same level of active chelating agent in your recipe.

Usage and Properties:

• Solubility: Both are water-soluble.
• Appearance: Both are liquid.
• Mixing: Can be mixed directly into the water phase of the formulation.
