Alkyldimethylethylbenzyl Ammonium Chloride

Updated: 2026-07-31

Overview

Alkyldimethylethylbenzylammonium chloride (ADBAC) is a quaternary ammonium compound known for its antimicrobial and surfactant properties. It is commonly used in disinfectants, sanitizers, and fabric softeners due to its ability to disrupt microbial cell membranes. This compound is part of the benzalkonium chloride family, which includes several variants with differing alkyl chain lengths. ADBAC is particularly valued for its stability and effectiveness in both industrial and household applications.

Physical and Chemical Properties

ADBAC is typically a colorless to pale yellow liquid with a mild odor. It is highly soluble in water and alcohol, making it easy to formulate into various solutions. The compound exhibits cationic properties, which contribute to its antimicrobial activity. Its density is approximately 0.98 g/cm³, and it is stable under normal storage conditions. However, it should be protected from extreme temperatures and direct sunlight to maintain its efficacy.

Main Applications

ADBAC is widely used in the production of disinfectants and sanitizers for healthcare, food processing, and household cleaning. Its ability to kill bacteria, viruses, and fungi makes it a key ingredient in many antimicrobial products. In addition to its disinfectant properties, ADBAC is used as a fabric softener and antistatic agent in the textile industry. Its surfactant properties also make it useful in industrial cleaning formulations.

Safety and Storage

ADBAC should be handled with care to avoid skin and eye irritation. Proper personal protective equipment (PPE), such as gloves and goggles, is recommended when working with this compound. Storage should be in a cool, dry place away from direct sunlight. Containers should be tightly sealed to prevent contamination and evaporation. In case of spills, absorb with inert material and dispose of according to local regulations.

B2B Procurement Guide

When procuring ADBAC, buyers should verify the CAS number (8001-54-5) to ensure they are receiving the correct compound. Purity levels should also be confirmed, as they can vary between suppliers. It is advisable to source from reputable suppliers who provide certifications such as ISO or GMP. Prices typically range from $10 to $50 per kg, depending on quantity and purity. Bulk purchases may offer cost savings for large-scale industrial users.
