  • SORBITAN MONOLAURATE (SORBİTAN MONOLAURAT)

    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 emulsifiers, wetting agents, and viscosity modifiers.

  • Sorbitan - Wikipedia

    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.

  • Glycerol monostearate - Wikipedia

    Glycerol monostearate, commonly known as GMS, is a monoglyceride commonly used as an emulsifier in foods. It takes the form of a white, odorless, and sweet-tasting flaky powder that is hygroscopic. Chemically it is the glycerol ester of stearic acid.
