Sorbitan monopalmitate

A series of sorbitol-based nonionic surfactants are used ia foods as water-ia-oil emulsifiers and defoamers. They are produced by reaction of fatty acids with sorbitol. During reaction, cycHc dehydration as well as esterification (primary hydroxyl group) occurs so that the hydrophilic portion is not only sorbitol but also its mono- and dianhydride. The product known as sorbitan monostearate [1338-41 -6] for example, is a mixture of partial stearic and palmitic acid esters (sorbitan monopalmitate [26266-57-9]) of sorbitol, 1,5-anhydro-D-glucitol [154-58-8] 1,4-sorbitan [27299-12-3] and isosorbide [652-67-5]. Sorbitan esters, such as the foregoing and also sorbitan monolaurate [1338-39-2] and sorbitan monooleate [1338-43-8], can be further modified by reaction with ethylene oxide to produce ethoxylated sorbitan esters, also nonionic detergents FDA approved for food use.

The stabilizer, gelled in the presence of ferric ions, is aptly selected from a hydro-lyzate of a copolymer of a vinyl monomer and an unsatd acid anhydride, or a water-sol acrylic polymer. Thus a preblend of AN I3O, aq HN03(60%) 60, NaNOg 10, MeOCH CH2-maleic anhydride copolymer hydrolyzate 6, and Fe2(S04)3 1 part was maintained at 43° and mixed with.a blend of paraffin 8, sorbitan monopalmitate 5, and mineral oil. 1 part, maintained at 32°. During mixing, sufficient air was introduced to yield a compn having a d...

Sorbitan monolaurate, sorbitan monopalmitate and sorbitan trioleate have also been used at concentrations of 0.01-0.05% w/v in the preparation of an emulsion for intramuscular administration. See Table IV.
