Product Introduction:

Dodecylethyldimethylammonium Bromide (DEDAB) is a quaternary ammonium compound (QAC) that functions as a powerful cationic surfactant. It typically appears as a white to off-white crystalline powder. DEDAB features a dodecyl (lauryl, C12) alkyl chain, two methyl groups, and one ethyl group attached to a positively charged nitrogen center.

This amphiphilic structure, with its balanced hydrocarbon chain length, makes it an effective antimicrobial agent, conditioning agent, and emulsifier, widely used in various personal care formulations and other industrial applications.

Main Uses:

1. Antiseptics and Disinfectants: DEDAB exhibits broad-spectrum antimicrobial activity against bacteria, fungi, and some viruses. It is widely used in antiseptic formulations, disinfectants for surfaces, and sanitizers, particularly in medical, food processing, and general hygiene applications.

2. Cosmetics & Personal Care (Hair Conditioning): It is a valuable ingredient in hair conditioners, rinse-off treatments, and some shampoos. Its cationic charge allows it to strongly adsorb onto negatively charged hair surfaces, providing excellent conditioning, detangling, softness, shine, and antistatic benefits.

3. Phase Transfer Catalysis: Due to its lipophilic quaternary ammonium cation, DEDAB can function as a phase transfer catalyst, facilitating reactions between reactants in immiscible organic and aqueous phases by transporting anionic reagents into the organic phase.

4. Surfactant and Emulsifier: Its cationic surfactant properties make it suitable as an emulsifier in various formulations, helping to stabilize oil-in-water or water-in-oil emulsions. It can also act as a wetting agent in industrial processes.

5. Research Reagent: In laboratory settings, it is used as a research reagent for studying surface chemistry, colloidal systems, and membrane interactions, often as a model QAC.
