Decyltrimethylammonium bromide CAS 2082-84-0 Typical Properties

Product Introduction:

Decyltrimethylammonium bromide (DTAB) is a quaternary ammonium compound (QAC) that functions as a cationic surfactant. It typically appears as a white crystalline powder. DTAB is characterized by its decyl (10-carbon) alkyl chain and a trimethylammonium head group, which is positively charged. This amphiphilic structure allows it to reduce surface tension and form micelles in aqueous solutions, making it useful in a wide array of applications, from industrial processes to personal care products and scientific research.

Main Uses:

1. Surfactant and Emulsifier: DTAB is primarily used as a cationic surfactant. It effectively lowers surface and interfacial tension, making it suitable for use as an emulsifier, wetting agent, and dispersant in various formulations.

2. Antimicrobial Agent and Disinfectant: Like many quaternary ammonium compounds, DTAB exhibits antimicrobial properties. It is incorporated into disinfectants, sanitizers, and antiseptic formulations due to its ability to disrupt bacterial cell membranes.

3. Cosmetics and Personal Care Products: It is used in cosmetics and personal care products as a conditioning agent (e.g., in hair conditioners), an antistatic agent, and a mild antimicrobial preservative.

4. Analytical Reagent and Research: In analytical chemistry and biochemistry, DTAB is frequently used in laboratory settings. It serves as a model cationic surfactant for studying micelle formation, protein solubilization, DNA complexation, and drug delivery systems. It is often employed in chromatography and electrophoresis.

5. Corrosion Inhibitor: Cationic surfactants can adsorb onto metal surfaces, forming a protective film that inhibits corrosion in certain environments.
