Dimethyldioctadecylammonium bromide

Description:

Dimethyldioctadecylammonium bromide, with the CAS number 3700-67-2, is a quaternary ammonium compound characterized by its long hydrophobic alkyl chains and a positively charged nitrogen atom. This compound typically appears as a white to off-white solid or powder and is soluble in organic solvents while being less soluble in water, reflecting its amphiphilic nature. It is commonly used as a surfactant, emulsifier, and antimicrobial agent in various applications, including pharmaceuticals, cosmetics, and industrial processes. The presence of two octadecyl groups contributes to its surface-active properties, allowing it to reduce surface tension and stabilize emulsions. Additionally, its quaternary ammonium structure imparts biocidal properties, making it effective against a range of microorganisms. However, its use must be carefully managed due to potential environmental and health impacts associated with quaternary ammonium compounds. Overall, dimethyldioctadecylammonium bromide is valued for its versatility in formulations requiring both surfactant and antimicrobial functions.

Dimethyldioctadecylammonium bromide

CAS: 3700-67-2

Dimethyldioctadecylammonium bromide is a cationic surfactant that is used as an antimicrobial agent. It has been shown to be effective against gram-positive and gram-negative bacteria and fungi. Dimethyldioctadecylammonium bromide also has the ability to bind to human immunoglobulin, which may be due to its disulfide bond structure. This surfactant has been shown to have biological properties in a model system, including optimum concentration and thermal expansion. The surface glycoprotein of the bacterium Pseudomonas aeruginosa is not affected by this surfactant, but it does show preferential binding for the protein that coats Staphylococcus aureus
