Propyl Paraben

Propyl Paraben is an antimicrobial preservative belonging to the ester family of p-hydroxybenzoic acid. It is more lipophilic (oil-soluble) than Methyl Paraben, making it particularly effective in the oil phases of emulsions and creams. It is widely recognized for its strong efficacy against molds and yeasts. As a staple in the pharmaceutical industry, it ensures the long-term microbial stability and safety of liquid and semi-solid medicinal preparations.

The product conforms to the specified requirements of the United States Pharmacopeia (USP), European Pharmacopoeia (EP), and/or British Pharmacopoeia (BP).
A detailed CoA is issued with every batch, outlining potency, purity profile, and microbiological testing verification.
A comprehensive Drug Master File is available to support registration submissions to regulatory authorities worldwide.
Production takes place in certified facilities that strictly adhere to current Good Manufacturing Practices (cGMP).
Functional Category:
Antimicrobial Preservative.
Chemical Formula:
C10H12O3.
Appearance:
White crystalline powder; odorless and practically tasteless.
Solubility:
Very slightly soluble in water; freely soluble in organic solvents such as ethanol, propylene glycol, and oils/fats.
Emulsions (Creams & Lotions)

Medical dermatological creams.

Due to its lipophilic nature, it concentrates in the oil phase to prevent fungal growth within the emulsion.

Oral Liquid Formulations

Solutions and suspensions.

Typically used in a 1:10 ratio with Methyl Paraben to achieve a "synergistic effect" covering a broad microbial spectrum.

Cosmeceuticals

Sunscreens and moisturizing medicated lotions.

Ensures the chemical and microbial stability of the product over long storage periods.

Parenterals (Injections)

Multi-dose injection vials.

Prevents accidental microbial contamination that may occur during repeated dosage withdrawals.

Regulatory Compliance

The product fully complies with the requirements specified in the United States Pharmacopeia (USP), the European Pharmacopoeia (EP), and/or food standards (FCC).

Synergistic Performance

When combined with Methyl Paraben, it provides a comprehensive preservative system that targets both Gram-positive/Gram-negative bacteria and fungi.

Chemical Purity

Rigorous testing for p-hydroxybenzoic acid and related impurities to ensure a superior safety profile.

Stability

Highly stable and resistant to hydrolysis under standard pharmaceutical manufacturing conditions.
