Sodium methylparaben is được sản xuất bởi reacting methylparaben with sodium hydroxide to form the water-soluble sodium salt. Its dramatically improved water độ hòa tan compared to the free acid form makes it particularly suitable for liquid and aqueous food systems where rapid and uniform dissolution is required. Sodium methylparaben dissociates in solution to release methylparaben, which provides antimicrobial activity against molds, yeasts, and bacteria.
It is effective across a wider pH range than many organic acid chất bảo quảns. It maintains efficacy from pH 3 to 9. Sodium methylparaben is commonly used in beverages, syrups, and liquid food sản phẩm where the limited độ hòa tan of free methylparaben would be problematic.
