  Sorbitan esters are nonionic lipophilic surfactants that are commonly used as water-in-oil (W/O) emulsifiers and stabilizers. Sorbitan fatty acid esters are produced by esterification of dehydrated sorbitol (sorbitan) with a variety of fatty acids. Sorbitol is a sugar alcohol that can be obtained by the reduction of glucose or derived from corn, potatoes, etc. The fatty acids commonly used to synthesize sorbitan esters include lauric acid, palmitic acid, stearic acid, and oleic acid.   Sorbitan esters used as non ionic surfactants are effective for various functions. Our range of surfactants is used in a variety of settings, for example, as an emulsifier in food, a stabilizer in a cosmetic cream formulation, or a cosolvent and antirust agent for petroleum and oil. These surfactants are sourced from vegetables and vegan friendly. They are safe and nontoxic as food additives when used according to regulations.   Our range of sorbitan esters has a hydrophilic-lipophilic ba...

  Polysorbate 80, also known as polyoxyethylene sorbitan monooleate, consists of sorbitol, ethylene oxide, and oleic acid. It has a molecular formula of C 64 H 124 O 26 . At room temperature, it is in the form of pale-yellow to amber oily liquid. It is an O/W emulsifier with a polysorbate 80 HLB value of 15.0.

Polyethylene glycol sorbitan monooleate  is a surfactant with numerous applications in food, pharmaceutical, and cosmetics; other than that, it can also use as an emulsifier for culture medium to reduce the surface tension of the medium, which enhances the growth of cells. Polyethylene sorbitan monooleate is also widely used in industrial productions such as use as a wetting agent and dispersant for photographic film making; as a stabilizer and foaming agent for polyurethane foaming plastic.  Huana is one of the leading polysorbate 80 suppliers and manufacturers in China, feel free to contac...

  What is Monostearate   Ⅰ. Introduction of sodium monostearate Sorbitan monostearate is a brown waxy substance that is insoluble in water, can disperse in hot water and soluble in hot oil, fatty acids and various organic solvents. It is resistant to acid and alkaline, and has good stability against metal ions. Sorbitan monostearate is compatible with nonionic, most anionic and cationic surfactants. It has numerous properties including emulsifying, dispersing, thickening and lubricating and more.   Sorbitan monostearate is an ester mixture of sorbitan and stearic acid. It is prepared by dehydratation of sorbitol and esterisificaiton with stearic acid under alkaline catalysis. It can also be prepared by direct estificaiton of sorbitol and stearic acid at 180 - 280°C.     Ⅱ. Functions of sorbitan monostearate: 1. As a W/O food emulsifier, sorbitan monostearate can be used alone or in combination with polysorbate 60, polysorbate 80 and polysorbate 65.   2. Acc...
