Description

Benzoic Acid, 4-Hydroxy-, Ethyl Ester, Mixt. With Methyl 4-Hydroxybenzoate And Propyl 4-Hydroxybenzoate is a defined mixture of parabens, a class of synthetic preservatives widely recognized for their efficacy against a broad spectrum of microorganisms. This synergistic blend offers enhanced antimicrobial activity and solubility profiles compared to single esters, making it a powerful tool for product stabilization. It is a critical ingredient for manufacturers in the cosmetics, personal care, pharmaceutical, and food industries seeking reliable, long-term protection against spoilage and contamination.

Application

• Cosmetic & Personal Care Preservative: Primary use in creams, lotions, shampoos, conditioners, and makeup to prevent microbial growth and extend shelf life.
• Pharmaceutical Formulations: Used as a preservative in topical ointments, creams, liquid oral preparations, and parenteral products where multi-ester blends are specified.
• Food & Beverage Industry: Employed as an antimicrobial agent (E214, E218, E216) in certain foodstuffs, sauces, and beverages, subject to regional regulatory approvals.
• Industrial Applications: Serves as a preservative in adhesives, industrial coatings, and functional fluids susceptible to biodeterioration.
• Animal Feed Additive: Used to preserve feed quality and prevent mold growth in stored feed products.
