Sorbitan monostearate is primarily used as an emulsifier to keep water and oils mixed. Sorbitan monostearate is used in the manufacture of food and healthcare products and is a non-ionic surfactant with emulsifying, dispersing, and wetting properties .
Test preparation— Transfer about 50mg of Glyceryl Monostearate,accurately weighed,to a glass-stoppered,25-mLconical flask,add by pipet 5mLof Internal standard solution,and mix to dissolve.Immerse the flask in a water bath maintained at a temperature between 45 and 50,and volatilize the chloroform with the aid of a stream of nitrogen.Add 3mLof Propionating reagent,and heat at 75 for 30minutes .
Sorbitan is a mixture of isomeric organic compounds derived from the dehydration of sorbitol and is an intermediate in the conversion of sorbitol to isosorbide. Sorbitan is primarily used in the production of surfactants such as polysorbates; which are important emulsifying agents, with a total annual demand of more than 10000 tons in 2012.

D-Sorbitol is a sugar alcohol that is commonly used as a sugar substitute.;Target: D-Sorbitol occurs naturally and is also produced synthetically from glucose. The food industry uses D-sorbitol as an additive in the form of a sweetener, humectant, emulsifier, thickener, or dietary supplement.
Manufacture: Sorbitol is produced by hydrogenation of a sugar solution using a nickel or ruthenium catalyst. Using ion exchange, the crude sorbitol solution is then …

Sorbitol can be used as a laxative when taken orally or as an enema. Sorbitol works as a laxative by drawing water into the large intestine, stimulating bowel movements. Sorbitol has been determined safe for use by the elderly, although it is not recommended without the advice of a doctor.
The term sorbitan describes the anhydride form of sorbitol, whose fatty acids are lipophilic whereas sorbitol body is hydrophilic. This bifunctionality in one molecule provides the basic properties useful in cleaners, detergents, polymer additives, and textile industry as …
