One of the most significant classes of nonionic surfactants containing nitrogen is ethanolamides of horse fatty acids. The conditions for the formation of nanoscale and submicron emulsions and the factors influencing the phase inversion temperature (SIT) and phase inversion composition (SIS) are examined. 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. Finding amides with nonionic foaming qualities in the presence of diethanolamines containing fatty acids extracted from horse fat is the aim of the study. In accordance with the reaction mechanism, amidation was performed using 400 grams of horse fatty acid (1.5 mol), 157.6 grams of diethanolamine (1.5 mol), and 3% of the Al2O3 catalyst (i.e., 12 grams) in relation to the total mass of fatty acid. The study’s Horse DEA surfactant’s HLB values were contrasted with those of other DEAs. As a local alternative to the popular Coconut DEA product for shampoo products, the Horse DEA developed in this scientific work has good solubility in oily environments with a DEA value of less than 10.
