Polyethylene glycol fatty acid diester

The EMEREST/TRYDET Ethoxylated Fatty Acids and Polyethylene Glycol Fatty Acid Esters are nonionic, specialized, mono and diesters of various fatty acids. These products can be prepared by the condensation or addition of ethylene oxide to a fatty acid at the site of its active hydrogen or by esterification of the fatty acid with polyethylene glycol. The chemical composition of the monoester product is represented by the general formula R-C0-(0-CH2CH2)n-OH where "R-CO"...

Such materials therefore usually contain free polyethylene glycol and diester in equimolar proportions. The spread of EO chain lengths is similar to that in alkylphenol ethoxylates. If they are made by esterification of polyethylene glycol, the spread of EO chain lengths obviously depends on the composition of the starting material, and the product always contains unreacted free fatty acid as well as diester and polyethylene glycol [2].

Direct ethoxylation of fatty acids and fats with conventional catalysts yields a complex mixture of mono- and diesters, as well as various polyethylene glycols as by-products, with a wide range in the number of polyethylene glycol units. Despite the inhomogeneity of the composition of the final product, they have found a wide use as emulsifiers in food, feed and technical applications and detailed studies of their emulsification and solubility/dispersibility properties have been carried out [57-59],...

These can be considered to be esters of fatty acids and polyethylene glycol, although they are generally made by direct addition of EO to the acid. They contain, besides the main monoester ingredient, diester, free acid, and free PEG. This class includes tall oil ethoxylates. Tall oil fatty acids are linear, long-chain, and unsaturated, being obtained by distillation of tall oil, a water-insoluble, ether-soluble fraction of pulp mill waste (3).
