Dodecyltrimethylammonium Bromide (1231-Br/DTAB)
CAS 1119-94-4
Dodecyltrimethylammonium Bromide (CAS 1119-94-4) is a high-performance cationic surfactant manufactured under strict ISO quality standards. Available as a white to pale yellow crystalline powder or in concentrated aqueous solutions (25%-50% active matter), it features high purity (≥98%), low free amine content, and a neutral pH range of 6.0-8.0 (1% solution). This versatile product is widely utilized as a core ingredient in industrial and institutional disinfectants due to its broad-spectrum antimicrobial efficacy. In personal care, it serves as an effective conditioning and antistatic agent in hair and skincare formulations. For research and material science, DTAB functions as a critical protein denaturant, cell lysis agent, and template for synthesizing mesoporous nanomaterials.
>> Main Uses
Dodecyltrimethylammonium Bromide (1231-Br/DTAB, CAS 1119-94-4) is a versatile cationic surfactant with broad utility across multiple sectors. Primarily, it serves as a highly effective active ingredient in industrial and institutional disinfectants, sanitizers, and algicides, providing reliable broad-spectrum antimicrobial action for surface and water treatment. In personal care and cosmetics, its conditioning properties make it essential in shampoos, conditioners, and skincare products for detangling, softening, and antistatic benefits. For scientific applications, DTAB is a fundamental reagent in biochemical research as a standard protein denaturant and cell lysis agent, while in material science, it acts as a key structure-directing template for synthesizing ordered mesoporous nanomaterials like MCM-41 silica. Additionally, its functionality extends to industrial processes as a softener and dye-leveling agent in textiles, a phase-transfer catalyst in organic synthesis, and a modifier in analytical chemistry.
