High-Quality Propyl Paraben (CAS Number: 94-13-3) -99% Purity Guaranteed, Fully Compliant with BP and USP Pharmacopoeial Standards for Cosmetic and P

Propylparaben More Info

Propylparaben (CAS 94-13-3), also known as propyl 4-hydroxybenzoate, is a synthetic ester of para-hydroxybenzoic acid. As a member of the paraben family, it is widely utilized as a preservative due to its broad-spectrum antimicrobial activity. Its molecular structure combines a hydrophilic phenolic group with a lipophilic propyl ester chain, enabling effective action against fungi, yeast, and bacteria. This compound is characterized by its white crystalline powder form and stability under typical storage conditions.

Mechanism of Antimicrobial Action

Propylparaben functions by disrupting microbial cell membrane integrity and inhibiting key enzymatic processes. Its lipophilic nature allows it to penetrate microbial cell walls, interfering with membrane transport and mitochondrial function. Studies indicate it effectively inhibits ATPase activity and nutrient uptake in target microorganisms. This dual mechanism ensures reliable preservation while maintaining compatibility with a wide range of formulations.

Industrial Applications and Uses

As a versatile preservative, Propylparaben is extensively employed in cosmetics, pharmaceuticals, and food products. In cosmetic formulations, it ensures the stability of creams, lotions, and shampoos by preventing microbial contamination. Pharmaceutical applications include its use in topical ointments, oral suspensions, and parenteral formulations. In the food industry, it serves as an additive to extend the shelf life of baked goods, beverages, and processed foods.

Synergistic Formulation Advantages

Propylparaben demonstrates enhanced efficacy when combined with other preservatives such as methylparaben or butylparaben. These synergistic combinations allow for lower usage concentrations while broadening the spectrum of antimicrobial activity. Its compatibility with diverse ingredients—including emulsifiers, surfactants, and active compounds—makes it a flexible choice for complex formulations. Additionally, it remains stable across a wide pH range, ensuring performance in varying product environments.

Quality Specifications and Compliance

Our Propylparaben meets stringent international standards, including USP, EP, and JP grades. Key specifications include a purity level of ≥99.5%, with controlled limits for impurities such as heavy metals and residual solvents. Each batch is accompanied by a Certificate of Analysis, ensuring transparency and compliance with global regulatory requirements. Our manufacturing processes adhere to GMP guidelines, guaranteeing consistency and reliability for industrial applications.

Safety Profile and Regulatory Status

Propylparaben is globally approved for use in cosmetics, pharmaceuticals, and food within established concentration limits. Regulatory bodies such as the FDA, EFSA, and SCCS have evaluated its safety, confirming its suitability for topical and oral applications. While debates about parabens persist, current scientific consensus supports its safety in regulated concentrations. We provide comprehensive toxicological data and regulatory guidance to assist customers in compliant product development.

Packaging and Storage Recommendations

To maintain stability and efficacy, Propylparaben should be stored in a cool, dry place away from direct sunlight. We offer packaging options ranging from 1 kg aluminum bags to 25 kg fiber drums, all designed to prevent moisture absorption and contamination. Proper handling includes the use of gloves and masks to minimize dust inhalation during industrial processing.
