The same material may also be designated polyoxyethylene glycol 400 stearate or macrogol stearate 400 in which case, the number 400 refers to the average molecular weight of the polymer chain.

Non-ionic Polyethylene glycol stearate - polyoxyethylene monostearate (Myrj), Sorbitan esters (Spans) and their ethoxylates (Tweens), Poloxamers (polyoxyethy-lene-polyoxypropylene block copolymers). 

Polyoxyethylene fatty acid esters are produced by the reaction of polyethylene glycols with fatty adds. The commercial products are waxy solids which include Carbowax 4000 (Mono) Stearate. Some of the products act as plasticizers and lubricants for plastics. The polyethylene glycols are soluble in water. 

Materials that are solubilized in polyethylene glycol can be solubilized in the polyoxyethylene chains on the surface of a nonionic micelle. Ismail, Gouda, and Motawi found that the micellar partition coefficients of barbiturates in polysorbates 20, 40, 60, and 80 is a function of the solute substituents and is proportional to the octanol-water partition coefficient of the barbiturate. Similarly, Ikeda, Kato, and Tukamoto showed that the solubilization of alkyl barbiturates by polyoxyethylene lauryl ether is not dependent upon the number of carbons in the substituents. Since the different polysorbates contain different aliphatic groups, the rather small dependence of solubilization upon polysorbate number (i.e., upon alkyl chain length) suggests that the barbiturates are not solubilized primarily in the hydrocarbon portion of the micelle. Gouda, Ismail, and Motawi showed that the solubilization of barbiturates in polyoxyethylene stearates is proportional to the number of polyoxyethylene units in the surfactant.
