Description

Domiphen Bromide is a versatile quaternary ammonium compound widely recognized for its potent antimicrobial and surfactant properties. This makes it an essential ingredient for formulators requiring effective biocidal action and surface activity. Key industries that rely on this compound include pharmaceuticals, personal care, and industrial disinfectants, where it serves as a critical component in preservative systems and sanitizing formulations.

Application

• Pharmaceutical Preservative: Used as an antimicrobial agent in topical formulations, eye drops, nasal sprays, and other multi-dose pharmaceutical preparations to prevent microbial contamination.
• Cosmetic & Personal Care Preservative: An effective ingredient in creams, lotions, shampoos, and other personal care products to extend shelf life and ensure product safety.
• Disinfectant & Sanitizer Formulations: A key active component in hospital-grade disinfectants, surface cleaners, and hand sanitizers due to its broad-spectrum efficacy against bacteria and fungi.
• Industrial Biocide: Employed in cooling water systems, fuel additives, and process streams to control microbial growth and biofouling.
• Ophthalmic Solutions: Serves as a preservative in contact lens solutions and other sterile irrigating solutions, valued for its compatibility and effectiveness at low concentrations.
• Research & Development: Used as a standard or reagent in microbiological studies and the development of new antimicrobial agents and preservative systems.

Quality Control

Our Domiphen Bromide is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets the high-purity standards required for pharmaceutical and cosmetic applications. A detailed Certificate of Analysis (COA), confirming identity, purity, and impurity profiles, is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality.
