What is Benzalkonium Chloride CAS 8001-54-5?

Benzalkonium Chloride, also called BAC or BKC, is a cationic quaternary ammonium compound with CAS 8001-54-5 and EC 616-786-9. It is a mixed alkyl benzyl dimethyl ammonium chloride system rather than a single pure molecule, and is normally supplied as an aqueous solution or concentrate.

Is Benzalkonium Chloride a single pure substance?

No. Commercial Benzalkonium Chloride is a mixture of alkyl benzyl dimethyl ammonium chlorides. Standard grades are often based mainly on C12 and C14 alkyl chains, so the alkyl distribution and active content are important product specifications, not just the CAS number.

What common Benzalkonium Chloride strengths are available?

Liquid grades commonly include about 50% and 80% active matter, while high-active powder forms are also available. Depending on grade, suppliers may specify active content, appearance, pH, free amine, color, and alkyl distribution, so the chosen strength should match the target formulation and use concentration.

What are the main uses of Benzalkonium Chloride?

It is used as a broad-spectrum antimicrobial and cationic surfactant in disinfectant concentrates, hard-surface sanitizers, industrial and institutional hygiene products, and water-treatment biocide or algaecide systems. In suitable products it is also used at low, controlled concentrations for preservative-related applications where local regulations permit.

Which compatibility issues should be checked with Benzalkonium Chloride?

Because BAC is cationic, it can be incompatible with anionic surfactants, soaps, and some complex anions, potentially reducing activity or causing separation. Formulators should check charge compatibility, dilution pH, and interaction with other actives before finalizing the formulation.

Benzalkonium Chloride CAS 8001-54-5

Benzalkonium Chloride is a quaternary ammonium compound widely used as a cationic surfactant and antimicrobial active in hygiene, cleaning, and related formulation systems. In commercial supply, it is typically handled as a solution-based product for formulation use rather than as a simple single-component pure substance. Supplier-side applications commonly focus on disinfectant concentrates, surface cleaning systems, sanitation products, and selected industrial formulations where cationic activity and formulation compatibility are required. Standard export supply can be arranged, with COA, TDS, and SDS available according to customer requirements. Polyhexamethylene Biguanide (PHMB) is a related polymeric antimicrobial active to compare where biguanide chemistry is required instead of a quaternary ammonium system.
