Product Overview

Propyl Paraben Sodium is the sodium salt of propyl paraben, widely used as an antimicrobial preservative in pharmaceutical, cosmetic, and personal care formulations. It offers excellent protection against molds and yeasts and is often used in combination with other parabens to achieve broad-spectrum preservation. Due to its good solubility in water compared to propyl paraben, Propyl Paraben Sodium is especially suitable for aqueous formulations.
