Product Description
What Is Dodecyl Dimethyl Benzyl Ammonium Chloride?
Dodecyl Dimethyl Benzyl Ammonium Chloride (DDBAC), a quaternary ammonium compound, is mainly used as a surfactant, antimicrobial agent, and disinfectant. It is widely employed in industrial cleaning, water treatment, and personal care products due to its effectiveness against bacteria, fungi, and viruses.
DDBAC is synthesized through a quaternization reaction between dodecyl dimethylamine and benzyl chloride. The reaction is conducted in a solvent, such as toluene or isopropanol, at temperatures between 60 and 80°C, with constant stirring to ensure uniformity throughout the process. After the reaction, the product is purified by filtration and washing to remove impurities, yielding a high-purity liquid or solid form.

User Asked Question:
Q: What is the difference between Dodecyl Dimethyl Benzyl Ammonium Chloride (DDBAC) and Dodecyltrimethylammonium Chloride (DTAC)?
A: DDBAC has a longer alkyl chain, offering better lubrication and antistatic properties, while DTAC has a shorter chain and is mainly used in surfactants and lubricants. DDBAC is ideal for cleaners, textile processing, and water treatment, while DTAC is more suitable for household cleaning and cosmetics. Additionally, DDBAC has better solubility in water, while DTAC is more soluble in organic solvents.
