Octadecyldimethylbenzylammonium Bromide (1827-Br/ODBAB)
CAS 22546-65-2
Octadecyldimethylbenzylammonium Bromide (CAS 22546-65-2) is a high-purity quaternary ammonium compound featuring a long C18 alkyl chain and a benzyl functional group. This cationic surfactant exhibits excellent surface activity, antistatic properties, and biocidal effects, making it a versatile ingredient across multiple industries. In personal care formulations, it serves as a premium hair conditioning and antistatic agent, improving wet and dry combing while reducing static fly-away. In material science, it functions as an effective organoclay modifier through ion exchange, enhancing the dispersion and compatibility of bentonite in polymer matrices for high-performance nanocomposites. Additionally, it finds broad industrial applications as a phase transfer catalyst in organic synthesis, an emulsifier for asphalt and silicone oils, and a protein flocculant in biochemical separation processes. The compound is typically supplied as a white to off-white crystalline powder with high purity and excellent stability under normal storage conditions.
>> Main Uses
