Sorbitan Esters & Polysorbates

Sorbitan esters and Polysorbates as nonionics offer many advantages over ionic surfactants including increase stability, enhance flexibility and provide wider compatibility. They are stable in mild acids, alkalis and electrolytes and do not react with ionic ingredients or actives. They are used as emulsifiers, foamers, defoamers, dispersants, lubricants, solubilizers, stabilizers, viscosifiers, diluents, wetting agents etc. Sorbitan Esters Sorbitan esters are nonionic surfactants that can be mixed with polysorbates in varying proportions to produce emulsions with a variety of textures and consistencies. They can dissolve in a variety of organic solvents as well as hot oil to create water in oil (W/O) emulsions. They are non-toxic and biodegradable, which can be used in foods, pharmaceuticals, cosmetics, textiles industry, and so on. Polysorbates Polysorbates (also known as Ethoxylated Sorbitan Esters) are formed by condensation of residual hydroxyl groups in sorbita...
