Coconut Oil Diethanolamide (CDEA), also known by its CAS number 68603-42-9 and numerous synonyms including Cocamide DEA, is a chemical compound that plays a significant role across various industries, most notably in personal care and household cleaning products. Its multifaceted properties stem from its unique chemical structure and synthesis process, making it a valuable ingredient for formulators worldwide. Understanding these aspects is key for any B2B professional involved in chemical sourcing and product development.

The synthesis of CDEA typically involves the condensation reaction between fatty acids derived from coconut oil and diethanolamine. This reaction can occur in molar ratios of 1:1 or 1:2. The specific ratio influences the quality of the final product. For instance, a 1:1 molar ratio generally yields higher quality diethanolamides with lower levels of residual ethylene glycol and free diethanolamine, making them suitable for more demanding applications and often requiring lower concentrations in formulations. The reaction is typically carried out at elevated temperatures, up to 170°C, often in the presence of an alkaline catalyst. This controlled process ensures the desired chemical transformation occurs efficiently and safely, with manufacturers focusing on optimizing yields and purity.

The resulting CDEA is typically described as a viscous, yellow to amber liquid. Its physical form and other chemical properties are critical to its functionality as a surfactant. Key characteristics include:

  • Excellent Surfactant Properties: CDEA exhibits remarkable wetting, washing, and emulsifying capabilities. It effectively reduces surface tension, allowing liquids to spread and penetrate more easily.
  • Foam Stabilization: Perhaps its most recognized attribute, CDEA is a potent foam booster and stabilizer. It works synergistically with anionic surfactants to create a dense, stable lather that enhances the user experience in products like shampoos and soaps.
  • Thickening and Viscosity Control: CDEA is an effective viscosity builder. It contributes significantly to the desired thickness and consistency of liquid formulations, such as liquid detergents and cleansers, improving their handling and application.
  • Mildness and Skin Compatibility: Derived from coconut oil, CDEA is generally considered mild and less irritating to the skin compared to some other surfactants. This makes it a preferred ingredient for sensitive skin formulations and baby products.
  • Hard Water Tolerance: When formulated with soap, CDEA can improve its performance in hard water conditions, reducing the formation of soap scum.

The applications of CDEA are diverse, driven by these beneficial properties. In the personal care industry, it is a staple in shampoos, body washes, hand soaps, and facial cleansers. It's also found in hair conditioners, lipsticks, and hair dyes, acting as an emulsifier and texturizer. The household cleaning sector heavily relies on CDEA for liquid detergents, dishwashing liquids, and various surface cleaners, where its thickening and foaming properties are highly valued. Beyond these consumer-facing markets, CDEA serves important roles in the textile industry as a fabric softener and detergent, and in certain industrial applications as a corrosion inhibitor in metalworking fluids and as an emulsifying agent in printing inks.

For businesses looking to buy Coconut Diethanolamide, understanding these fundamental properties and synthesis methods empowers informed procurement decisions. Reliable manufacturers and suppliers, particularly those offering competitive prices from regions like China, are crucial for ensuring a consistent supply of this vital chemical raw material. By partnering with experienced suppliers of CAS 68603-42-9, formulators can confidently integrate CDEA into their product development, leveraging its proven performance benefits.
