Product Description
What is Dioctyl Dimethyl Ammonium Chloride?
Dioctyl Dimethyl Ammonium Chloride (DODMAC), a quaternary ammonium compound, serves various purposes, including as a disinfectant, surfactant, and fabric softener. Acclaimed for its robust antimicrobial efficacy, it demonstrates remarkable effectiveness in combating both gram-positive and gram-negative bacteria. This versatility makes it highly beneficial in applications such as water treatment, cleaning products, and textile processing.
Preparation Method:
DODMAC is synthesized through quaternization, where dimethylamine reacts with octyl chloride under controlled conditions (50°C–80°C) in a solvent like ethanol. The reaction produces DODMAC as the main product, which is then purified via washing and drying. Its excellent emulsifying and antistatic properties make it versatile for industrial and personal care applications.

User Asked Question:
Q: What distinguishes DODMAC from Cetrimonium Chloride?
A: Dioctyl Dimethyl Ammonium Chloride (DODMAC) and Cetrimonium Chloride are both quaternary ammonium compounds but serve different functions. DODMAC is primarily used in industrial cleaning and water treatment, while Cetrimonium Chloride is mainly used in hair care products as a conditioning agent and antistatic agent. DODMAC excels in cleaning and water treatment applications, whereas Cetrimonium Chloride is widely found in cosmetics and personal care products.
