Description

Hexadecylguanidine Monohydrochloride is a cationic surfactant and antimicrobial agent derived from the combination of a long-chain alkyl group and a guanidine moiety. This compound is valued for its potent biocidal and surface-active properties, making it a critical functional ingredient in formulations requiring dual-action performance. It is primarily utilized by manufacturers in the disinfectant, personal care, and industrial preservation sectors.

Application

• Broad-Spectrum Disinfectants & Sanitizers: Effective active ingredient in formulations for hard surface, skin, and instrument disinfectants.
• Cosmetic & Personal Care Preservation: Used as a preservative in creams, lotions, and shampoos to inhibit microbial growth.
• Industrial Biocides: Incorporated into cooling water systems, metalworking fluids, and paints to prevent bacterial and fungal contamination.
• Agricultural Formulations: Serves as a component in pesticide and fungicide formulations for its surfactant and efficacy-enhancing properties.
• Textile & Leather Processing: Acts as a softening agent and antimicrobial treatment for fabrics and hides.
• Research & Development: Used as a biochemical tool and reference standard in microbiological and surface chemistry studies.

Quality Control

Our Hexadecylguanidine Monohydrochloride is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and performance. A Certificate of Analysis (COA) documenting key parameters such as assay, impurity profile, and microbiological status is provided with every 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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect quality.
