Cocamide DEA (CAS No.: 68603-42-9), also known as 6501, Ninol, or coconut fatty acid diethanolamide, is a nonionic alkanolamide surfactant synthesized from natural coconut oil. The product has a molecular weight of approximately 280-300, with a molecular formula represented by mixtures such as C11H23CON(CH2CH2OH)2. Its HLB value ranges from 3.6 to 5.8, cloud point exceeds 100°C, making it a typical water-in-oil emulsifier while also exhibiting excellent water solubility.
This product belongs to Guoli Chemical's 6501-80% specification, meaning its active matter content is controlled at a high concentration of 78.0%~82.0%. Compared to common 1:1 type or 1:2 type 6501 on the market, it offers significantly higher thickening efficiency. The amine value of the product is 120~160 mgKOH/g, hydroxyl value is 220~280 mgKOH/g, and both acid value and saponification value are controlled at low levels (≤5 and ≤10 mgKOH/g, respectively), indicating complete raw material reaction, low impurity content, and high product purity.
In terms of compatibility, this product has good compatibility with anionic, cationic, and amphoteric surfactants. Especially when compounded with main surfactants such as AES (sodium alcohol ether sulfate) and LAS (linear alkylbenzene sulfonate), it exhibits significant synergistic thickening effects, making it an indispensable core additive in washing, care, and cleaning formulations.
