Description

Sodium Paraben is the sodium salt of para-hydroxybenzoic acid, a widely used and highly effective preservative. Its primary value lies in its broad-spectrum antimicrobial activity against molds, yeasts, and bacteria, ensuring product stability and shelf-life extension. This compound is essential for manufacturers in the cosmetics, personal care, pharmaceutical, and food industries seeking a reliable and water-soluble preservative solution.

Application

• Cosmetics & Personal Care: A key preservative in creams, lotions, shampoos, conditioners, and makeup to prevent microbial spoilage.
• Pharmaceuticals: Used as an antimicrobial agent in topical ointments, liquid formulations, and parenteral products.
• Food & Beverage: Employed as a food additive (E219) to preserve flavorings, sauces, pickles, and certain beverages.
• Industrial Applications: Acts as a preservative in adhesives, glues, and other aqueous-based industrial products.
• Animal Feed: Used to prevent mold growth in feed ingredients and finished products.
