Didecyl dimethyl ammonium chloride Usage And Synthesis

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

Bardac(R) 22 is a quaternary ammonium based antimicrobial used as a bacteriostat, deodorant, disinfectant and(or) a microbiocide.

Uses

Uniquat(R) 2250 is an effective cationic surfactant that can be used in a variety of cleaning systems.

Uses

Didecyl Dimethyl Ammonium Chloride is a compound that exhibits some fungacidal and antimirobial functions.

Uses

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.

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.
