Benzalkonium Chloride 80% (BKC 80%) Structure and Formula

Benzalkonium Chloride (BKC) is not a single-formula compound — it is a mixture of alkylbenzyldimethylammonium chlorides. Each molecule has a quaternary nitrogen centre carrying four substituents: a benzyl group (C₆H₅CH₂–), two methyl groups (CH₃), one long straight-chain alkyl group (R, ranging from octyl C₈ to octadecyl C₁₈), and a chloride counter-ion (Cl⁻). Because commercial BKC is a blend of alkyl chain lengths — typically dominated by C₁₂ (dodecyl), C₁₄ (tetradecyl), and C₁₆ (hexadecyl) homologs — the technical product does not have one single molecular formula or molecular weight; instead it has the average molecular weight (354.0 g/mol for BKC 80%'s typical C₁₂–C₁₆ distribution) and a formula range shown below.

General (mixture) formula

C₆H₅CH₂N(CH₃)₂RCl, where R = a straight-chain alkyl group from C₈H₁₇ to C₁₈H₃₇

Searches for a single fixed formula such as "C22H40ClN" for Benzalkonium Chloride refer to one specific alkyl-chain homolog within the BKC family — C22H40ClN corresponds to the C14 (tetradecyl / myristyl) dimethylbenzylammonium chloride homolog, CAS 139-08-2, not the CAS 8001-54-5 technical mixture sold commercially. The table below lists the exact formula for each common homolog so the correct one can be identified for regulatory or formulation cross-referencing.

Alkyl Chain	Homolog Name	CAS No.	Molecular Formula	Mol. Weight
C₈ (octyl)	Octyldimethylbenzylammonium chloride	959-55-7	C₁₇H₃₀ClN	283.9 g/mol
C₁₀ (decyl)	Decyldimethylbenzylammonium chloride	17301-53-0	C₁₉H₃₄ClN	311.9 g/mol
C₁₂ (dodecyl / lauryl) — dominant homolog	Dodecyldimethylbenzylammonium chloride	139-07-1	C₂₁H₃₈ClN	340.0 g/mol
C₁₄ (tetradecyl / myristyl)	Tetradecyldimethylbenzylammonium chloride	139-08-2	C₂₂H₄₀ClN	354.0 g/mol
C₁₆ (hexadecyl / cetyl)	Hexadecyldimethylbenzylammonium chloride	122-18-9	C₂₄H₄₄ClN	382.1 g/mol

Frequently Asked Questions

What is Benzalkonium Chloride 80% (BKC 80%) and who uses it?+

Benzalkonium Chloride 80% is a high-active 80% aqueous concentrate of Alkyl Dimethyl Benzyl Ammonium Chloride (ADBAC, CAS 8001-54-5) — the same active substance as BKC 50% but at higher concentration. It is the export-economical grade preferred by global disinfectant brands, sanitiser blenders, cosmetic preservation houses, water-treatment chemical companies, and EPA-registered formulators who dilute on-site to 50%, 25%, 10%, or final-use concentrations. Bulk buyers shipping internationally choose 80% to reduce freight cost per kilogram of active matter shipped.

Why choose BKC 80% over BKC 50%?+

BKC 80% delivers 60% more active quat per kilogram of shipped product than BKC 50% — the freight saving on ocean exports to Latin America, Africa, and the Middle East is significant. It also requires less storage volume on-site. The trade-offs: BKC 80% is more viscous, may form a soft gel below 15°C (warm storage 20–25°C is recommended), and requires gentle warming or vigorous mixing to dilute into water. Choose 80% if you dilute on-site or pay high freight per kg. Choose 50% if you formulate as-is or pump the product directly through metering equipment at room temperature.

How do I dilute BKC 80% to make BKC 50% or final-use concentration?+

To make BKC 50% from BKC 80%: blend 62.5 kg of BKC 80% with 37.5 kg of demineralised water (mass ratio) — yields 100 kg of BKC 50%. For final-use disinfectant of 0.1%–0.4% active, dilute 1.25–5.0 g of BKC 80% per litre of water (1 part BKC 80% in 200–800 parts water). Always add BKC concentrate to water (not water to concentrate) to avoid heat spots, use demineralised or low-hardness water (avoids Ca/Mg precipitation), and gently warm BKC 80% to 25–30°C if it has gelled. Validate final active content by titration (BS EN 16370 or USP <081>) before commercial use.

Is BKC 80% from Vasudev Chemo Pharma equivalent to Lonza Bardac® 2280, Stepan BTC® 8358, or Nouryon Maquat® 4480-E?+

Yes. Our BKC 80% is functionally equivalent to Lonza Bardac® 2280, Stepan BTC® 8358, Nouryon (AkzoNobel) Maquat® 4480-E, and Pilot Lonzabac® 80% — all 80% ADBAC concentrates with C₁₂–C₁₆ alkyl distribution. Our typical alkyl ratio (C₁₂ 40–50% / C₁₄ 30–40% / C₁₆ 10–20%) matches the global formulation reference standard used by EPA-registered disinfectant brands and formulators. Customers cross-qualifying our product report drop-in replacement performance in surface disinfection, water-treatment, and preservative applications. We provide spec-comparison documents and trial samples (1–5 kg) on request.

How should BKC 80% be stored to prevent gelation?+

BKC 80% should be stored between 15°C and 40°C in sealed HDPE drums or IBCs, away from direct sunlight. Below 15°C, BKC 80% becomes viscous and can form a soft gel that takes time to redissolve. If gelation occurs, gently warm the drum to 25–30°C for 24–48 hours and roll/agitate to homogenise — the product fully recovers without loss of activity. For winter storage in cold climates (Russia, northern Europe, northern China), insulated warehousing or heated bulk-tank storage is recommended. Shelf life is 24 months in original sealed packaging.

What is the freight saving when buying BKC 80% versus BKC 50%?+

BKC 80% contains 1.6× more active matter per kilogram than BKC 50% (80% vs 50% active). For an order of 10 MT of active quat: BKC 50% requires 20 MT of shipped product (10/0.5); BKC 80% requires 12.5 MT (10/0.8). The 7.5 MT freight saving per order is significant — typically USD 600–1,500 saving on ocean freight to Latin America or West Africa, or USD 300–700 on Middle East shipments. Add storage-space savings on-site and the total cost-of-ownership advantage of 80% over 50% is meaningful for bulk formulators.

What grades of BKC 80% are available?+

BKC 80% is supplied in three grades, identical to BKC 50%: (1) Industrial / Technical Grade for cleaning concentrates, water treatment, and oilfield biocide blending; (2) Cosmetic Grade (CTFA-compliant, INCI: Benzalkonium Chloride) for cosmetic preservative formulators who dilute to use concentration; (3) Disinfectant Grade suitable for EPA-registered formulators producing hospital, food-contact, and pharmaceutical surface sanitisers. All grades produced at our ISO 9001:2015, GMP, and Halal certified facility in Gujarat, India, with full COA, SDS, TDS, Halal, and GMP documentation.

Is BKC 80% compatible with anionic surfactants?+

No. Like BKC 50%, BKC 80% is a cationic surfactant and is generally incompatible with anionic surfactants — LABSA, SLES, SLS, sodium cumene sulfonate (SCS), sodium xylene sulfonate (SXS), and most soap systems. Mixing forms an insoluble ion-pair complex that precipitates and destroys biocidal activity. BKC IS compatible with nonionic surfactants (alcohol ethoxylates, APGs, Tween), amphoteric surfactants (cocamidopropyl betaine when pH > IEP), and other cationic/quat systems. Pre-test all formulations for clarity, stability, and biocidal performance before scale-up.

What is the typical dosage of BKC 80% in disinfectant formulations?+

For ready-to-use surface disinfectants (0.1%–0.4% active): use 0.125%–0.5% BKC 80% in finished formulation.
