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.

Product Description

Benzalkonium Chloride (BAC/BKC) CAS 8001-54-5 is a cationic quaternary ammonium compound with EC 616-786-9.

Synonyms: Alkyldimethylbenzylammonium chloride; Alkylbenzyldimethylammonium chloride; BAC; BKC.

CAS: 8001-54-5.

Molecular formula: Not applicable (mixed alkyl benzyl dimethyl ammonium chloride system).

It is normally supplied as a clear to slightly yellow aqueous solution or concentrate.

Commercial Benzalkonium Chloride is a mixture of alkyl benzyl dimethyl ammonium chlorides rather than a single pure molecule.

Common commercial strengths include about 50% and 80% active matter, with high-active powder forms also available.

It is used as a broad-spectrum antimicrobial and cationic surfactant in disinfectant and hygiene formulations.

It is commonly selected for disinfectant concentrates, hard-surface sanitizers, and industrial and institutional hygiene products.

It can also be used in water-treatment biocide or algaecide systems at suitable concentrations.

Confirm active content, alkyl distribution, appearance, pH, free amine, and color for the chosen grade.

As a cationic compound, check compatibility with anionic surfactants, soaps, and some complex anions.

Store in tightly closed original containers in a cool, dry, well-ventilated area away from direct sunlight and heat.

Use appropriate PPE and prevent spills or contamination.

Confirm packaging suitable for the concentration and order quantity, and follow the current SDS.

Every batch is checked for active content, appearance, pH, free amine, and color, with COA/TDS/SDS supplied per grade.

Confirm active content, alkyl distribution, packaging, and grade as required.
