CDEA Chemical, commonly known as Cocamide DEA, is an important ingredient used in a wide variety of personal care and household cleaning products. It acts as a foaming, stabilizing, and thickening agent that helps products such as shampoos, soaps, and detergents form stable and creamy foam. The term CDEA stands for Cocamide Diethanolamine, which is produced by reacting fatty acids derived from coconut oil with diethanolamine.
In today’s world, where almost everyone uses cleansing products daily, CDEA Chemical plays a major role in enhancing their quality and performance. It improves texture, makes foam last longer, and provides a smoother feel when applied. In this complete guide, we’ll explore everything about CDEA Chemical — its formula, properties, manufacturing process, and practical applications in daily life and industries.
Chemical Formula and Structure of CDEA Chemical
The chemical formula of CDEA Chemical is CH₃(CH₂)nC(O)N(CH₂CH₂OH)₂, where n varies depending on the type of fatty acid obtained from coconut oil. Its molecular structure contains both hydrophilic (water-attracting) and hydrophobic (oil-attracting) sections. This unique combination makes it a surfactant, allowing it to mix oil and water easily.
CDEA appears as a thick, pale yellow liquid that blends smoothly with other surfactants and dissolves well in water. Because it is partly derived from natural coconut oil, CDEA Chemical is considered milder and gentler compared to many synthetic surfactants, making it ideal for personal care formulations.
How is CDEA Chemical Manufactured?
The production of CDEA Chemical involves a reaction between coconut oil fatty acids and diethanolamine. The ingredients are heated together under specific conditions, leading to the formation of Cocamide DEA and water as a byproduct.
The simplified reaction is as follows:
Coconut oil fatty acids + Diethanolamine → Cocamide DEA + Water
After the reaction, the mixture is purified to remove unwanted residues, leaving behind a clean, yellowish, and viscous liquid. Manufacturers prefer CDEA Chemical because it is affordable, stable, and provides consistent results in a wide range of products.
