Cocamide DEA (Diethanolamine)

Cocamide DEA 85% – Foam Booster and Viscosity Enhancer

Cocamide DEA 85% is a nonionic surfactant derived from coconut fatty acids and diethanolamine. It is widely used in household cleaning and personal care formulations because of its foam-boosting, foam-stabilizing, and viscosity-enhancing properties. It is commonly incorporated into shampoos, liquid hand washes, dishwashing liquids, and other detergent formulations to improve product performance and consistency. The designation “85%” refers to the supplier's specified grade or concentration and should be verified against the product's Technical Data Sheet (TDS) and Certificate of Analysis (COA).

Chemical Properties and Functions: Cocamide DEA is valued for its ability to improve the quality and stability of foam in surfactant-based formulations. When combined with primary surfactants such as Sodium Laureth Sulfate (SLES) or Linear Alkylbenzene Sulfonate (LABSA)-based systems, it can enhance lather and help produce a richer, longer-lasting foam. It also acts as a viscosity modifier, helping formulators achieve the desired thickness in liquid cleansing products. Its nonionic character allows it to work alongside many anionic and amphoteric surfactants, although compatibility and performance depend on the complete formulation.
