Description

Heptadecyltrimethylammonium Bromide is a high-purity quaternary ammonium salt (quat) surfactant and cationic agent. This compound is valued for its potent antimicrobial properties and ability to modify surface charges, making it a critical functional additive in advanced formulations. It is primarily sought by manufacturers in the pharmaceutical, personal care, and specialty chemical industries for applications requiring reliable biocidal activity or cationic conditioning.

Application

• Pharmaceutical Intermediate & Biocide: Used in the synthesis of antiseptic and disinfectant formulations, including those for surgical scrubs and wound care products.
• Personal Care & Cosmetics: Acts as a conditioning agent and preservative in hair conditioners, skin creams, and other leave-on or rinse-off formulations.
• Textile & Fabric Softener: Serves as a key cationic softener and antistatic agent for textiles, providing a soft hand feel and reducing static cling.
• Industrial Biocide: Employed in cooling water systems, paper mills, and oilfield operations for microbial control and as a slimicide.
• Analytical Chemistry & Research: Utilized as a phase-transfer catalyst (PTC) in organic synthesis and as a reagent in various laboratory research applications.
• Surface Modification & Nanotechnology: Functions as a cationic surfactant for stabilizing nanoparticles and modifying the surface properties of materials like silica and clays.

Quality Control

Our Heptadecyltrimethylammonium Bromide is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay by HPLC and identification by FT-IR, to ensure it meets precise specifications for purity and performance. A comprehensive Certificate of Analysis (COA) documenting identity, purity, and related substances 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, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
