Propyl Paraben Sodium – Water-Soluble Cosmetic Preservative

Every well-crafted cosmetic formulation deserves protection that works as hard as the actives inside it. Propyl Paraben Sodium is a trusted, water-soluble preservative that guards your products against the invisible threats of bacterial, yeast, and mold contamination — quietly extending shelf life and maintaining the integrity of your formulation from the first use to the last.

As the sodium salt of Propyl Paraben, it offers a key advantage over its parent compound: significantly improved solubility in water-based systems. This means faster, more uniform incorporation into aqueous formulations, with no need for elevated temperatures or additional solvents. It simply dissolves, distributes, and gets to work.

Key Benefits

• Broad-Spectrum Antimicrobial – effective against bacteria, yeast, and mold across a wide range of formulation types
• Water-Soluble – dissolves easily in aqueous systems for uniform distribution without extra processing
• Extends Shelf Life – prevents microbial spoilage and maintains product safety over time
• Stable & Reliable – consistent preservative performance across a broad pH range
• Versatile – compatible with a wide variety of cosmetic and pharmaceutical formulations

Applications

• Creams, lotions & moisturizers
• Serums & gel formulations
• Shampoos & hair conditioners

Formulation Tips

Add to the water phase during formulation for easy dissolution. Works synergistically with other parabens (such as Methyl Paraben Sodium) for broader antimicrobial coverage. Always conduct Preservative Efficacy Testing (PET) on your final formulation to confirm adequate protection. Ensure your formulation pH falls within the effective range of 4–8 for optimal performance.
