Description

Propyl 4-Hydroxybenzoate EP, NF, FCC

Propyl 4-Hydroxybenzoate EP, NF, FCC is a high-purity preservative used in pharmaceutical, nutraceutical, cosmetic, and food applications for its broad-spectrum antimicrobial activity. Compliant with European Pharmacopoeia (EP), National Formulary (NF), and Food Chemicals Codex (FCC) standards, it is widely used to inhibit the growth of molds, yeasts, and certain bacteria in aqueous and semi-solid systems.
Propyl 4-Hydroxybenzoate is chemically designated as Propyl 4-Hydroxybenzoate. It appears as a white or almost white crystalline powder that is sparingly soluble in water and freely soluble in alcohol and organic solvents. Its physicochemical properties make it especially useful in preserved formulations requiring long-term stability.
In pharmaceutical and related applications, Propyl 4-Hydroxybenzoate EP, NF, FCC is used in:
• Oral liquid and semi-solid dosage forms as a preservative
• Topical creams, gels, lotions, and ointments
• Cosmetic and personal care products
• Food and nutraceutical formulations requiring antimicrobial protection
• Combination preservative systems with Methyl 4-Hydroxybenzoate
• Research involving preservative efficacy and formulation stability
Propyl 4-Hydroxybenzoate EP, NF, FCC functions by disrupting microbial membrane transport processes and inhibiting growth of spoilage organisms. It is often used in combination with other parabens to broaden preservative effectiveness across diverse pH ranges and formulation types.
