EMSORB Sorbitan Fatty Acid Esters

EMSORB Sorbitan Fatty Acid Esters, or polyol esters, are created by the two basic mechanisms of dehydration and esterification. Sorbitol, with six hydroxyl groups, is dehydrated, undergoing ring closure with the loss of two hydroxyl groups. The cyclic sorbitan moiety is produced. Through the esterification reaction, hydrophobic fatty acids are combined with the sorbitan, thereby decreasing its hydrophilic attributes. The exact degree of hydrophllicity depends on the size and number (mono-, di-, tri-) of acid molecules added to one sorbitan molecule.

EMSORB Ethoxylated Sorbltan Esters are the hydrophilic counterparts to the hydrophobic EMSORB Sorbltan Fatty Acid Esters. Varying moles of ethylene oxide are added to the Sorbltan Patty Acid Ester to produce these materials. The more ethylene oxide added the more hydrophilic the molecule becomes as seen by its increased Hydrophile-Lipophile balance Value (HLB). 

EMSORB Ethoxylated Sorbltan Esters are based on oleic, stearic and lauric fatty acids. Their hydrophilic character makes these nonionic materials ideal for the preparation of oil-in-water (O/W) emulsions. They can emulsify mineral and vegetable oils, fats, solvents and waxes. When used as co-emulsifiers with the EMSORB Sorbltan Patty Acid Esters, a wide range of HLB values can be created to obtain the optimum value or required HLB for any desired emulsion, either oil-in-water or water-inoil. 

HENKEL CORP. EMERY GROUP EMSORB Sorbitan Fatty Acid Esters  

EMSORB Sorbitan Fatty Acid Esters are lipophilic emulsifiers and coupling agents serving as integral components of emulsif-iable Industrial mold release agents, textile fiber and yarn lubricants, and textile finishing softeners. They are widely used as surfactants and functional components in many kinds of Industrial and household products. 

These products are frequently used in conjunction with more hydrophilic emulsifiers, particularly their polyoxyethylene derivatives. When used alone or with other emulsifiers, they are very effective for the preparation of both W/O and O/W emulsions. 

Is an oil soluble emulsifier, coupling agent, lubricant, and softener for textile fibers and leather. It can be used with water soluble emulsifiers in formulating clear emulsif-iable concentrates of petroleum oils and waxes, natural fats and waxes, and alkyl esters. Small amounts will usually clarify (couple) such concentrates. EMSORB 2500 is also widely used in cosmetics and household products. 

Is a primary emulsifier for water in oil systems and an effective co-emulsifier for oil in water systems for mineral oil, fats, and waxes. It is also a versatile coupling agent for water soluble materials in O/W systems. Suggested applications include its use as a W/O emulsifier for consumer household aerosols and as an O/W co-emulsifier for cosmetics, industrial oils and textile oils.
