Benzalkonium Chloride 50% is an aqueous solution composed primarily of alkylbenzyldimethylammonium chlorides, offering a pH range of approximately 6-8 when diluted to a 10% solution. Its specific gravity ranges from 0.96 to 1.00 at 25°C, indicating its density relative to water. BKC acts as a cationic surfactant, effectively reducing surface tension, and works as a phase-transfer agent. Buyers need to consider the concentration and formulation compatibility, ensuring it aligns with the intended use. This grade is ideal for standard applications, offering a balance of efficacy and ease of use, and is commonly available in larger industrial packaging like 200 kg drums.
