1、What is benzalkonium chloride？
Benzalkonium chloride (BZK, BKC, BAK, BAC), also known as alkyl dimethyl bromide amine (ADBAC), trade name Zephiran, is a cationic surfactant. It is an organic salt, divided into quaternary ammonium compounds. 3 main uses of ADBAC are biocides, cationic surfactants, and phase transfer agents. ABAC is a mixture of alkyl bromide amine; alkyl has various even alkyl chains.
Benzalkonium chloride is a quaternary
ammonium preservative and disinfectant. Its role and use are similar to other
cationic surfactants. It can also be used as an antibacterial preservative for
pharmaceutical products.
There are many non-bleach products on the
market, and one good alternative is quaternary ammonium compounds (Quat), of
which benzalkonium chloride is an example. It does not remove limescale from
showers and toilets. It is just bleach. Even when used as a bleaching agent, it
can damage fabrics because it weakens the fabric.
Oil and gas.
Biocorrosion is the main danger in the oil
and gas production industry. Benzalkonium chloride (BAC50 and BAC80) is used to
control the activity of sulfate-reducing bacteria (SRB) in waters rich in
sulfates, causing a buildup of ferrous sulfide, which causes pitting of steel
equipment and piping.SRB is also associated with good acidification, leading to
the release of toxic H2S gas. Other applications of benzalkonium chloride
include improving oil recovery efficiency through demulsification and mud
breaking.
Disinfectant and detergent-disinfectant
manufacturing.
Due to its non-toxic, non-corrosive,
non-contaminating, and non-polluting properties, benzalkonium chloride is a
major active use in disinfectants and disinfectant prescriptions for
healthcare, personal hygiene, public sector safeguarding agriculture, and food
supply. BAC50 and BAC80 safely incorporate germicidal and cleaning properties
into hygiene products, enhancing penetration, removing dirt, and disinfecting
surfaces.
Pharmaceuticals and Cosmetics.
Benzalkonium chloride has a margin of
safety for use in a wide range of leave-on skin disinfectants and infant
hygiene wipes. BAC50 is widely used as a preservative in ophthalmic,
rhinological, and otologic agents and an emollient and adsorbent in optimized
formulations.
Water treatment.
Benzalkonium chloride-based formulations
are used in water sewage treatment and swimming pool algae removal.
Aquaculture.
Benzalkonium chloride improves sanitary
conditions and reduces the need for antibiotics in aquaculture. Benzalkonium
chloride is used for water treatment, removal of fish parasites, general site
disinfection, and prevention of infectious fish and shellfish diseases.
Wood protection.
World environmental issues are safer in
wood protection, with biodegradable benzalkonium chloride replacing persistent
chlorinated biocides. Bioactive carbon has excellent bactericidal and
algae-solubilizing properties and is also very effective against other complex
organisms.
Pulp and paper industry.
Benzalkonium chloride is a general biocide
used for slime control and odor management in pulp mills. It can improve paper
handling and give strength and antistatic properties to paper products.
Textile industry.
Benzalkonium chloride is used to protect
natural fibers from molds and fungi and as an insect repellent. Dyeing acrylic
fibers with cationic dyes is also a permanent delaying agent.
Leather industry.
Benzalkonium chloride inhibits the growth
of leather molds and mildew and promotes the softening, wetting,, and leather
dyeing.
Horticulture and household.
Benzalkonium chloride is very effective
against molds, mildews, mosses, fungi and algae and can be used to clean and
prepare all types of surfaces: greenhouses, roofs, paths, wood preparation.
Chemical industry.
Quaternary ammonium compounds are used in
chemical applications in the chemical industry, such as precipitating agents,
oil/water, and air/water interfaces for their ability to position themselves as
phase transfer catalysts, emulsifiers/re-emulsifiers, etc.
Polymers and Coatings.
Quaternary ammonium compounds are widely
used in the coatings industry (paints, wood treatment, electronics, etc.) as
antistatic agents, emulsifiers, and preservatives).
