Sodium Methyl Paraben
Sodium Methyl Paraben is the sodium salt of methylparaben, a widely used preservative in cosmetics, pharmaceuticals, and food. It is a white, odorless, crystalline powder that is water-soluble and effective against a broad spectrum of bacteria, molds, and yeasts. As a paraben derivative, it helps prevent microbial contamination and extends shelf life. It is often preferred over methylparaben in formulations where water solubility is required.
