Cetyldimethylethylammonium Bromide, identified by CAS number 124-03-8, is a compound that plays a significant role as a chemical auxiliary in numerous industrial applications. As a cationic surfactant, its molecular structure allows it to interact effectively with various surfaces and molecules, making it a valuable component for formulators and R&D scientists. Understanding the scientific basis of its utility is crucial for anyone looking to buy this versatile chemical.

At its core, Cetyldimethylethylammonium Bromide is a quaternary ammonium salt. This structure grants it amphiphilic properties, meaning it possesses both hydrophilic (water-loving) and hydrophobic (water-repelling) parts. This dual nature is what makes it an excellent surfactant, enabling it to reduce surface tension and create stable emulsions or dispersions. The cationic charge on the nitrogen atom further dictates its behavior, allowing it to adsorb onto negatively charged surfaces, which is key to its function as an antistatic agent and its antimicrobial activity.

Key Scientific Properties and Applications

The efficacy of Cetyldimethylethylammonium Bromide as a chemical auxiliary is rooted in its chemical and physical properties:

  • Surfactant Properties: Its primary role as a surfactant allows it to act as an emulsifier, stabilizer, and wetting agent. This is critical in creating homogenous mixtures in products like cosmetics, paints, and agricultural formulations.
  • Antimicrobial Activity: The cationic head group can disrupt the cell membranes of microorganisms, leading to cell death. This makes it an effective disinfectant and preservative, essential for products requiring microbial control. If you are looking to purchase a potent antimicrobial agent, this compound is a strong candidate.
  • Antistatic Functionality: By attracting moisture to surfaces and dissipating electrical charges, it prevents static build-up in plastics, synthetic fibers, and other materials. This is a vital application in industries where static discharge can be problematic.
  • Flocculation: In wastewater treatment or industrial separation processes, it can aggregate fine particles, aiding in their removal from liquid streams.

For researchers and product developers, sourcing high-quality Cetyldimethylethylammonium Bromide from a reliable manufacturer or supplier is critical. The availability of pure material ensures predictable performance in these applications. When considering where to buy CAS 124-03-8, prioritizing suppliers that offer technical data and consistent quality is key. Partnering with an experienced chemical manufacturer ensures you get the precise chemical auxiliary you need for your innovative formulations, often at a competitive price.
