Potassium Propylparaben

Product Description

Potassium Propylparaben is the water-soluble potassium salt of propylparaben, manufactured in our professional facility to provide an efficient preservation solution for high-water-content cosmetic systems. By converting the standard ester into its salt form, we significantly increase its solubility in aqueous phases while maintaining its potent antimicrobial mechanism of disrupting microbial membrane integrity. This ingredient is a vital commercial asset for formulators who require the proven reliability of parabens in cold-process formulations where rapid dissolution and high stability are paramount.

Product Specification

• INCI Name: Potassium Propylparaben
• CAS No.: 35285-69-9
• Chemical Name: Potassium Propyl 4-hydroxybenzoate
• Product Type: Preservative / Chemical
• Appearance: White crystalline powder
• Purity (Assay): ≥ 99.0%
• Solubility: Highly soluble in water
• Water Content: ≤ 5.0%

Key Benefits & Applications

• Excellent Water Solubility: Ideal for aqueous formulations where standard propylparaben is difficult to incorporate, eliminating the need for heating or organic solvents.
• Broad-Spectrum Fungistatic Activity: Specifically targets yeasts and molds, providing a robust second line of defense in complex microbial control strategies.
• Low Concentration Efficacy: Delivers high preservative power at low usage levels, minimizing the potential for skin irritation while ensuring product safety.
• Cold Process Compatibility: Perfect for heat-sensitive active ingredients, as it can be easily integrated into the formulation at room temperature.
• Applications: Extensively used in water-based serums, clear shampoos, facial toners, and lightweight hydrogels.

Formulation Guidelines

• Suggested Dosage: 0.01% – 0.1% (Concentration based on active Propylparaben content).
• pH Stability: Maintains maximum stability and efficacy within a pH range of 4.0 – 8.0.
• Processing: Directly add to the water phase with gentle stirring; dissolution is rapid even at room temperature.
• Compatibility: Highly compatible with a wide array of surfactants and thickening agents; however, monitor the final pH as it may slightly increase the alkalinity of the solution.
• Synergy: Combine with Sodium Hyaluronate to balance the preservative system with deep hydration, minimizing the risk of dryness and enhancing the overall skin comfort of the formulation.
