Cetyldimethyl(2-hydroxyethyl)ammonium bromide

Description:

Cetyldimethyl(2-hydroxyethyl)ammonium bromide, with the CAS number 20317-32-2, is a quaternary ammonium compound characterized by its surfactant properties. It typically appears as a white to off-white solid or a viscous liquid, depending on its formulation and temperature. This compound is amphiphilic, meaning it possesses both hydrophilic (water-attracting) and hydrophobic (water-repelling) regions, which makes it effective in reducing surface tension and stabilizing emulsions. It is commonly used in personal care products, such as shampoos and conditioners, due to its conditioning and antimicrobial properties. Additionally, it can function as a cationic surfactant, providing antibacterial effects and enhancing the texture of formulations. Cetyldimethyl(2-hydroxyethyl)ammonium bromide is soluble in water and can interact with various other ingredients in formulations, making it versatile in cosmetic and pharmaceutical applications. Safety data indicates that, while generally regarded as safe in appropriate concentrations, it should be handled with care to avoid skin and eye irritation.
