Benzethonium Chloride is a broad-spectrum, highly efficient, low-irritation, and stable quaternary ammonium cationic surfactant. Combining the triple functions of germicidal, preservative, and surfactant properties, it is widely used in pharmaceuticals, daily chemicals, disinfection, and personal care, serving as a core raw material for high-end disinfection and preservation systems.
Product Advantages
1.Broad-Spectrum & High Efficiency: Effective against Gram-positive/negative bacteria, fungi, and enveloped viruses, providing long-lasting bacteriostasis for 4–8 hours.
2.Low Irritation & High Safety: Significantly less irritating to the skin than Benzalkonium Chloride; mucosal-friendly and compliant with pharmacopoeia and cosmetic standards.
3.Excellent Stability: Strong formulation compatibility, resistant to decomposition, long shelf life, and suitable for various dosage forms.
4.Multifunctional: Combines germicidal, preservative, and surfactant properties in one, simplifying formulations and reducing costs.
