(Benzalkonium Chloride)
 
The HESTERQUAT line BKC (Benzalkonium Chloride) are quaternary ammonium salts of the class of cationic surfactants, being a non-oxidizing biocide. It is widely used in producing household disinfectants, hospital, personal care and animal husbandry. In biocidal detergents, provide dual properties with high efficacy against bacteria, algae, fungi and enveloped viruses which can be used in concentrations (ppm) extremely low.

The line HESTERQUAT BKC is also penetrating and dispersing properties with the advantage of low toxicity, and being soluble in water makes its convenient use, and is not affected by water hardness.

The line HESTERQUAT BKC, can also be used as anti-mold agent, antistatic, emulsifying agent and changing fields in tissue and dyeing.

Textile industry

Solutions of benzalkonium chloride, the base is used as moth repellents and retarding the permanent dyeing acrylic fibers with cationic dyes.

Water treatment and wastewater pools
Enters the algaecides formulation.
 
Pisciculture
Reduces the need for harmful antibiotics in aquaculture, by improving hygiene. It is used in water treatment and localized sanitization, the removal of parasites and prevention of infectious diseases in fish and shellfish.
 
Wood protection
The global concern for the environment has led to increased replacement safely chlorinated biocides, and being biodegradable, has Benzalkonium chloride is increasingly being used in the product formulations for wood protection with excellent fungicidal properties and algaecides and highly effective against other bodies in combined formulations.
 
Tanneries

Alkyl Dimethyl Benzyl Ammonium Chloride

The HESTERQUAT BKC - 50, is a version of benzalkonium chloride in aqueous solution. He is best known, and widespread use, as a germicide, quaternary ammonium. Benzalkonium chloride, as generally mentioned, is obtained from the high purity fatty coconut oil fatty acids, to follow the rigid specification of the international pharmacopoeia. It is a stable product under a wide pH range, which means its dissolution and activity on any PH value. The absorption and thus the antimicrobial effect of HESTERQUAT BKC - 50, increases with increasing pH. In the table below it can be seen antimicrobial power relative to high pH, and the values given are low concentrations in mg / l of HESTERQUAT BKC-50, which reduces the number of microorganisms by a factor of 10,000 after 5 and 10 minutes, respectively.

Alkyl Dimethyl Benzyl Ammonium Chloride

He is best known, and widespread use, as a germicide, quaternary ammonium, is included in almost all pharmacopoeias and corresponds to the generic chemical notation "ALKYL DIMETHYL BENZYL AMMONIUM CHLORIDE OF".

Benzalkonium chloride, as generally mentioned, is obtained from the high purity fatty coconut oil fatty acids, to follow the rigid specifications of the International Pharmacopoeia, representing the radical ALKYL mixture of C8 H17 to C18 H37, In these coconut oil fatty acids are present in a constant proportion, and the radical corresponds to ALKYL mixture containing approximately 67% C12, 25% C14, 7% C16 and 1% C8 + C10 + C18. The phenolic coefficient of Benzalkonium Chloride of pharmacopoeia is Staphylococcus AUREOS, 275 and SALMONELLA typhosa, 250.

With the advent of modern technology, it was possible to distill and separate the fatty acids of coconut oil and enrich the mixture with the highest percentage of C14, this known as the most germicidal action and resistance to hard water
