Description

Sodium Methylparaben is the sodium salt of methylparaben, a widely used synthetic preservative. It offers superior water solubility compared to its parent compound, making it an efficient and versatile antimicrobial agent in aqueous formulations. This product is essential for manufacturers requiring broad-spectrum protection against bacteria, yeast, and molds. It is a critical ingredient for the personal care, pharmaceutical, and food industries to ensure product safety and extend shelf life.

Application

• Personal Care & Cosmetics: Primary preservative in shampoos, conditioners, lotions, creams, and liquid soaps.
• Pharmaceuticals: Used as an antimicrobial preservative in topical ointments, liquid oral medications, and parenteral formulations.
• Food & Beverage: Employed as a food additive (E219) to preserve flavorings, sauces, and certain beverages.
• Industrial Applications: Acts as a preservative in adhesives, paints, and other water-based industrial products.

Quality Control

Our Sodium Methylparaben is manufactured under strict quality management systems. It can be produced to meet various pharmacopoeial standards, including USP-NF, EP, and JP, as well as food-grade specifications like FCC. Every batch undergoes rigorous analytical testing to ensure identity, purity, and performance. A comprehensive Certificate of Analysis (COA) is provided with each shipment to guarantee compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture.
