Properties:
Alkyl Dimethyl Benzyl Ammonium Chloride is a kind of cationic surfactant, belonging to nonoxidizing boicide. 
It can efficiently withhold algae propagation and sludge reproduction. 
Alkyl Dimethyl Benzyl Ammonium Chloride also has dispersing and penetrating properties, can penetrate and remove sludge and algae, has advantages of low toxicity, no toxicity accumulation, soluble in water, convenient in use, unaffected by water hardness. 
Alkyl Dimethyl Benzyl Ammonium Chloride can be also used as anti-mildew agent, antistatic agent, emulsifying agent and amendment agent in woven and dyeing fields.

Alkyl Dimethyl Benzyl Ammonium Chloride is commonly used as a surfactant and antibacterial agent, and is commonly found in household cleaning products.


Benzalkonium chlorides (BACs) are chemicals with widespread applications due to their broad-spectrum antimicrobial properties against bacteria, fungi, and viruses

Benzalkonium chloride is an organic salt used in cleaning agents, classified as a quaternary ammonium cationic detergent. 

Benzalkonium chlorides (BACs), also known as alkyl dimethyl benzyl ammonium chlorides, alkyl dimethyl (phenylmethyl) quaternary ammonium chlorides, ammonium alkyl dimethyl (phenylmethyl) chlorides, or ammonium alkyl dimethyl benzyl chlorides, are a class of quaternary ammonium compounds (QACs). 
They are usually commercialized as a mixture of compounds with different lengths for the alkyl chain, ranging from C8 to C18, with higher biocide activity for C12 and C14 derivatives

BACs are also among the most common active ingredients in disinfectants (4) used in residential, industrial (7), agricultural, and clinical settings


Alkyl Dimethyl Benzyl Ammonium Chloride is primarily used as a preservative and antimicrobial agent, and secondarily used as a surfactant. Alkyldimethylbenzylammonium chloride works by killing microorganisms and inhibiting their future growth, and for this reason frequently appears as an ingredient in antibacterial hand wipes, antiseptic creams and anti-itch ointments. In cosmetics, its antimicrobial properties are employed to protect products from spoiling. It’s mostly used in personal care products like rash creme, foot odor powder, facial lotion, cleanser, makeup and sunscreen.

The mechanism of bactericidal/microbicidal action is thought to be due to disruption of intermolecular interactions. This can cause dissociation of cellular membrane lipid bilayers, which compromises cellular permeability controls and induces leakage of cellular contents. is a quaternary ammonium antiseptic and disinfectant with actions and uses similar to those of other cationic surfactants. Alkyldimethylbenzylammonium chloride is also used as an antimicrobial preservative for pharmaceutical products. For most multidose aqueous nasal, ophthalmic and otic products, Alkyldimethylbenzylammonium chloride is the preservative of choice. It has been used in eye drops as a preservative since the 1950’s and it is still the most common preservative used in ophthalmic solutions at a concentration of 0.01–0.02%. It is an effective bactericidal and fungicidal agent that helps to minimise the growth of organisms in multidose containers

Alkyldimethylbenzylammonium chloride is further used as a preservative in more than 200 medicinal products for the nasal route of administration and about 10 preparations for inhalation use are authorised on EU markets based on the additional survey performed amongst a limited number of member states. Only a few medicinal products containing Alkyldimethylbenzylammonium chloride are intended for other routes of administrations i.e. cutaneous, oral, oromucosal, rectal, vaginal and parenteral use.


Alkyl Dimethyl Benzyl Ammonium Chloride is a quaternary ammonium compound and it is the most commonly used antimicrobial preservative.

Usage Methods:
As nonoxidizing boicide, dosage of 50-100mg/L is preferred; as sludge remover, 200-300mg/L is preferred, adequate organosilyl antifoaming agent should be added for this purpose. 
This product can be used together with other fungicidal such as isothiazolinones, glutaraldehyde, dithionitrile methane for synergism, but cannot be used together with chlorophenols. 
If sewage is appeared after thrown of this product in circulating cool water, the sewage should be filtered or blown off in time to prevent their deposit in bottom of collecting tank after froth disappearance.
No blending with anion surfactant.

Package and Storage: 25kg or 200kg in plastic barrel, or confirmed by clients. Storage for two year in room shady and dry place.

Safety Protection: A little smell of almond, no visible stimulation to skin. When contacted, flush with water.
