Didecyl dimethyl ammonium chloride Chemical Properties,Uses,Production

Description

Didecyldimethylammonium chloride is a quaternary ammonium compound used as detergent/disinfectant in hospitals, as algicide in swimming pools, and as a fungicide and against termites in wood. This compound caused contact dermatitis in a hospital employee, also sensitive to glyoxal and bis-(aminopropyl)- laurylamine.

Chemical Properties

Liquid

Uses

Didecyl Dimethyl Ammonium Chloride is a compound that exhibits some fungacidal and antimirobial functions. It can be used as general purpose disinfectant, sanitizer; mildew preventative in commercial laundries; water treatment in cooling towers and oil field flood waters; wood preservative.

Definition

ChEBI: Didecyldimethylammonium chloride is an organic molecular entity.

Flammability and Explosibility

Flammable

Agricultural Uses

Biocide, Fungicide, Bactericide, Herbicide, Algaecide, Algaecide, Bacteriocide, Fungistat, Microbiocide, Microbiostat disinfectant, Viricide, Tuberculocide, Molluscide, Insecticide: General purpose disinfectant used on hard, nonporous surfaces as a sanitizer; mildew preventative, wood preservative, and to kill algae, phytopathogenic fungi, phytopathogenic bacteria. An active ingredient in a large number of disinfectant products registered with USEPA and labeled with a claim to inactivate “avian influenza A” viruses on hard surfaces.

Trade name

ALIQUAT 203; BARDAC® 22; BARDAC® 2250, 2270, 2280

Contact allergens

This quaternary ammonium compound is used as a detergent-disinfectant in hospitals, as an algaecide in swimming pools, as a fungicide, and against termites in wood. We observed severe contact dermatitis in a slaughterhouse worker using a liquid soap containing this product (personal observation). Immediate-type manifestations like urticaria and dyspnoea have been reported.

Synthesis

In the presence of potassium iodide, chlorodecane reacts with methylamine to produce bis-decyl methyl tertiary amine, which is then reacted with chloromethane under pressure in a medium of water and isopropanol, heated and pressurized, to produce a product of bis-decyldimethylammonium chloride.
