Cocamide DEA (Cocamide DEA), trade name Ninol, is a nonionic surfactant produced by condensation of coconut oil with diethanolamine, with CAS number 68603-42-9. Its active matter content is as high as 92%, and it appears as a light yellow to amber transparent viscous liquid. With its excellent thickening performance, efficient foam stabilization and foaming ability, good detergency, and emulsifying dispersibility, this product has become an indispensable multifunctional additive in the daily chemical and industrial cleaning fields.
The greatest technical advantage of this product lies in its nonionic nature—it is highly compatible with anionic, cationic, and amphoteric surfactants, offering strong formulation adaptability. At the same time, its resistance to alkali and hard water allows it to maintain stable performance in high-alkalinity and hard water environments, greatly expanding its application scenarios.
Functionally, Cocamide DEA can significantly increase system viscosity in the presence of salt, reducing the amount of thickener needed; it synergizes with anionic surfactants to markedly improve foam richness and persistence; it has good emulsifying ability for oily components, effectively removing grease and dirt, and enhancing the cleaning effect of formulations.

Formulation Compatibility Suggestions: Cocamide DEA is a nonionic surfactant that works best when compounded with anionic surfactants (such as AES, LAS), significantly improving system thickening response and foam performance. When used in salt-containing systems, the thickening effect is particularly prominent, effectively reducing the need for additional thickeners and lowering formulation costs.
Priority of Recommended Applications: As a preferred thickener and foam stabilizer in personal care formulations like shampoo and shower gel; as a secondary surfactant to enhance viscosity and grease removal in dishwashing detergents and hard surface cleaners; as an emulsifying dispersant in industrial degreasers, working synergistically with other primary surfactants. In textile and leather processing fields, it is recommended to use as a component of auxiliary formulations, with specific dosage determined by experiments based on process requirements.
Dosage Reference: According to the product database of Guoli Chemical, there is no standard value for recommended dosage. It is suggested that users determine the optimal addition ratio through experiments based on the target formulation system. Generally, in liquid detergent formulations, an addition range of 1%~5% can achieve significant thickening and foam stabilization effects.
