CDEA 85% chemical name is coconut oil fatty acid diethanolamide, abbreviated as CDEA. 6501 belongs to non-ionic surfactants and has no cloud point. It is a viscous liquid with a pale yellow to amber color, easily soluble in water, and has good functions such as foaming, foam stabilization, penetration and stain removal, and resistance to hard water.
There are two common processing methods for CDEA 85%:
(1) The direct reaction between refined oil and diethanolamine, also known as one-step method. In practical applications, alkyl alcohol amides are usually made from fatty acids (FA) and excess diethanolamine (DEA) (1:2, 1:1.5 types) to ensure complete reaction of fatty acids. The resulting product is an equimolar amide DEA complex with good water solubility. This method has a low cost, but the product color is deep, and the content of alkyl alcohol amide is only about 70%, so it lacks competitiveness in the international market. Currently, small and medium-sized manufacturers in China mostly use this method. (2) The ester exchange reaction between coconut oil and alcohol produces lauric acid ester, which then reacts with diethanolamine to produce the product Also known as two-step method. At present, large domestic and foreign enterprises adopt the advanced methyl ester method, which has a low reaction temperature, produces products with light color, good transparency, and high thickening performance. The content of diethanolamide lauric acid can reach over 85%. And ours is made using the second method, with a 1:1 source of food grade coconut oil. The production process is as follows:
Coconut oleic acid diethanolamide has properties such as wetting, washing, emulsifying, and softening, and has a good foam stabilizing effect on anionic surfactants. It is an essential ingredient in various cosmetics such as liquid detergents, liquid soaps, shampoos, cleaning agents, and facial cleansers. When used with soap, it has good resistance to hard water. It can also be used as an emulsion stabilizer for cream products, with high stability at low temperatures, good flowability, active ingredient content ≥ 85%, and no jelly formation at low temperatures.
