Bardac^® LF 18-50 WT is synergistic with oxidizing biocides and prevents algae growth, lowering the need for halogens. Bardac^® LF 18-50 WT is compatible with anionic scale and corrosion inhibitors, which can result in a decrease of operating costs.  Bardac^® LF 18-50 WT is water soluble and is not a dermal sensitizer.

Bardac^® LF 18-50 WT is low-foaming tendency compared to other ADBAC-based products.  Low-foam is an advantage in recirculating cooling systems and decorative fountains.

• Active ingredient: 50% Dioctyl Dimethyl Ammonium Chloride
• Available in drums, IBC’s and bulk

Bardac LF 18-50 WT Product Information Document

The Bardac^® 2250 product shows a broad spectrum of activity against both gram-positive and gram-negative bacteria and is also effective on fungi and viruses, including those that are enveloped. Showing a high tolerance to hard water (above 350ppm), it remains active in the presence of heavy organic soiling. Its impressive surfactant and wetting properties make it one of the multipurpose biocides of choice for cooling systems and swimming pool water treatment as part of formulations.

This Bardac^® 2250 product displays synergistic effects in combination with aldehydes and complexing agents, such as EDTA, but is incompatible with anionic detergents. It is registered in a large number of countries for numerous applications, including water treatment applications as well as hygiene and material protection applications.

Please check local regulations or consult your Lonza representative for further information.

• Contains 50% solution of Dialkyl Dimethyl Ammonium Chloride (DDAC)
• Shows a high tolerance to hard water (above 350ppm)
• Available in drums, IBC’s and bulk

Barquat^® CB50 (50% active ingredient) and CB80 (80% active ingredient) products are blends of Alkyl Dimethyl Benzyl Ammoniumchlorides. Showing a broad-activity spectrum, the products are effective as micro-biocides, however are less effective as an algaecide and fungicide. Carbon chains (being centred in particular on C12 and C14) offer an interesting profile as a bactericide due to the adsorption of its cationic radical on the anionic bacterial cell surface, leading to the disorganization of the cytoplasmic membrane.

Available in drums and IBC’s.

The Barquat^® DM range is a grade of Alkyl Dimethyl Benzyl Ammonium Chlorides acting as an effective algaecide and biocide, which has 50% (DM50) or 80% (DM80) actives, respectively.

Their well-defined carbon chain distribution makes Barquat^® DM50 and DM80 products effective for biological corrosion control and for sulphate-reducing bacteria in water systems.

Available in drums and IBC’s.

When used as an active ingredient in water treatment formulations, these products have been found to provide effective biocidal action against a broad spectrum of microbial organisms such as bacteria, fungi, viruses and algae. This “first” generation quaternary ammonium compound delivers potent germicidal action in cooling water applications. The Barquat^® MB50 and MB80 products are blends of Alkyl Dimethyl Benzyl Ammonium Chlorides. 

Available in drums, IBC’s and bulk.

The Barquat^® 1552 solution is a mixed Alkyl chain Dimethyl Benzyl and Dialkyl Methyl Benzyl Ammonium Chloride that can be used in a variety of water treatment applications. When used as an active ingredient in a formulation such as a hard surface disinfectant and/or certain types of water treatment applications, this product is effective as a broad-spectrum biocide against microbial organisms such as bacteria, fungi, viruses and algae.

Available in totes and bulk.

The Carboshield^® 1000E product is comprised of a blend of didecyl dimethyl ammonium carbonate and didecyl dimethyl ammonium bicarbonate. Unlike traditional chloride quaternaries, this non-chloride quaternary provides excellent corrosion inhibition properties on steel, aluminum, iron, brass and copper.  

It can be used as a cationic surfactant, a thin film forming corrosion inhibitor or a wetting/dispersion agent. It is hard-water tolerant and requires little or no additional sequestering agents for effective performance. The Carboshield^® 1000E product is compatible with numerous nonionic surfactants as well as many dyes and fragrances.

• Water miscible and can be emulsified in oil
• Amenable to aqueous (freshwater and seawater) and non-aqueous systems
• Exhibits effective inhibition properties for steel, aluminum, iron, brass and copper
• Can be used in the oil and gas industry
• To be dosed via metering pumps
• Available in drums, IBC’s and bulk
