Dodecyl trimethyl ammonium bromide CAS:1119-94-4

Dodecyl trimethyl ammonium bromide, also known as DTAB or DTB, is a quaternary ammonium compound commonly used as a surfactant or detergent. It is a white, solid powder that is soluble in water.

DTAB is often utilized in various industries and applications, including personal care products, pharmaceuticals, and research laboratories. It can act as a cleaning agent, emulsifier, foaming agent, or wetting agent.

In personal care products, DTAB can be found in shampoos, conditioners, soaps, and body washes. It helps to create a lather, increase product stability, and improve the spreadability of the formulation.

In pharmaceuticals, DTAB is used in the formulation of various drug delivery systems, including microemulsions, nanoemulsions, and liposomes. It aids in drug solubilization and stabilization, enhancing drug absorption and effectiveness.

In research laboratories, DTAB is frequently employed in biological and biochemical studies. It can be used for membrane protein extraction and purification, DNA extraction, and gene delivery systems.

Application and Effect

Surfactant: DTAB is a cationic surfactant, meaning it has a positively charged head group. It reduces surface tension and increases the wettability of liquids, allowing it to act as a detergent or cleaning agent.

Antimicrobial Agent: Due to its cationic nature, DTAB exhibits antimicrobial properties. It can disrupt bacterial cell membranes and inhibit the growth of various microorganisms, making it useful in disinfectants and sanitizing solutions.

Emulsifier: DTAB can form stable emulsions by reducing the interfacial tension between immiscible liquids. It is commonly used in emulsion polymerizations and the formulation of stable oil-in-water emulsions.

Phase Transfer Catalyst: DTAB can facilitate the transfer of species between immiscible phases, enabling reactions that would otherwise be hindered due to poor solubility. It is widely used in organic synthesis and extraction processes.

DNA Purification: DTAB is commonly used in DNA extraction procedures. It helps in precipitating and separating DNA from cellular debris and other contaminants, allowing for the isolation and purification of genetic material.

Cosmetics and Personal Care Products: DTAB is used in various cosmetic formulations, including shampoos, conditioners, and body washes. It acts as a foam enhancer, emulsifier, and stabilizer, improving the overall performance and feel of the product.

Pharmaceutical Formulations: DTAB can be found in pharmaceutical formulations, especially in drug delivery systems. It aids in solubilizing poorly soluble drugs and improving their absorption and bioavailability.
