Synthesis and Production Technology of Horse Dea Surfactant by Amidation of Ot Fatty Acids With Diethanolamine

Ethanolamides of horse fatty acids are one of the most important classes of nitrogen-containing nonionic surfactants. These products are widely used as components of detergents, foaming agents, and stabilizers in cosmetic preparations, wetting agents and antistatic agents, dispersants, corrosion inhibitors, etc. The conditions for the formation of nanoscale and submicron emulsions and the factors affecting the phase inversion temperature (SIT) and phase inversion composition (SIS) are analyzed. The purpose of the research: to obtain amides with nonionic foaming properties in the presence of diethanolamines with fatty acids extracted from horse fat. According to the experiment, amidation was carried out using 400 grams of horse fatty acid (1.5 mol), 157.6 grams of diethanolamine (1.5 mol), and 3% of the Al ₂ O ₃ catalyst (i.e., 12 grams) relative to the total mass of fatty acid, as per the reaction mechanism. The HLB values of the Horse DEA surfactant obtained from the study were compared with other DEAs. In conclusion, the Horse DEA created in this scientific work has good solubility in oily environments with a DEA value of less than 10, demonstrating its properties as a local substitute for the widely used Coconut DEA product for shampoo products.
