Cocamide DEA, trade name Ninol, with CAS number 68603-42-9, is a non-ionic alkylolamide surfactant prepared by condensation of coconut oil with diethanolamine. This product has an active content of over 92%, and compared to conventional 80% grade products, it has more outstanding thickening efficiency, foam stability, and compatibility. It is a multifunctional additive widely used in household chemicals and industrial cleaning.
The molecular formula of this product is a mixture such as C₁₁H₂₃CON(CH₂CH₂OH)₂, with a molecular weight of about 287, belonging to a medium-viscosity non-ionic surfactant. Its HLB value is between 6 and 7, with both hydrophilicity and lipophilicity, easily dispersible and soluble in water, with a cloud point range of 80~90°C. Under the temperature conditions of conventional liquid detergent formulations, it can stably exert thickening and foam stabilizing effects.
Cocamide DEA 92% has good chemical stability, excellent alkali resistance and hard water resistance, and good compatibility with anionic, cationic, and amphoteric surfactants. Its foam is rich, fine, and stable, significantly improving the overall user experience of the formulation system.
