Propyl p-Hydroxybenzoate, commonly known as Propyl Paraben or by its CAS number 94-13-3, is a chemical compound with a significant role in various industries due to its unique properties. NINGBO INNO PHARMCHEM CO.,LTD. is a key supplier of this versatile ingredient, and this article explores its chemical characteristics and wide-ranging applications.

Chemically, Propyl Paraben is the n-propyl ester of p-hydroxybenzoic acid. It typically presents as a white crystalline powder, with a melting point between 95-98°C. Its molecular formula is C10H12O3, and it possesses a molecular weight of approximately 180.20 g/mol. A key characteristic is its low volatility, contributing to its stability in various formulations. The compound is synthesized through the esterification of 4-hydroxybenzoic acid with propanol, a process that involves an acidic catalyst. This method ensures a high purity product, meeting the stringent specifications required for its use as a chemical reagent.

The primary utility of Propyl Paraben lies in its potent preservative capabilities. It acts as a broad-spectrum bactericide, effective against a range of microorganisms including gram-positive bacteria, feminine germs, and saccharomycetes. This antimicrobial action is crucial for extending the shelf life of products by preventing microbial spoilage. The low application concentration required, typically 0.2% to 0.5%, makes it an economically viable and efficient preservative solution. Many consumers are looking to buy Propyl Paraben for its efficacy and affordability.

The applications of Propyl Paraben are extensive. In the cosmetic industry, it is a widely used ingredient in products such as lotions, creams, shampoos, and makeup to prevent bacterial and fungal growth. Its stability across a broad pH range (4.5–7.5) is advantageous for maintaining product integrity. Similarly, in the food industry, Propyl Paraben serves as a food additive, preserving baked goods, beverages, and other processed foods. Its role in inhibiting mold and yeast growth is vital for food safety and quality. The use of propyl paraben as a food preservative is a critical aspect of food manufacturing.

Furthermore, Propyl Paraben finds significant use in the pharmaceutical sector. It acts as a preservative in various drug formulations, including oral medications, syrups, and topical preparations. Its ability to maintain the sterility and efficacy of pharmaceutical products is crucial for patient health. The identification test for Propyl Paraben confirms its suitability for pharmaceutical grade applications. The market for propyl paraben in pharmaceutical manufacturing is robust.
