We can also offer kinds of natural non ionic surfactantfor sale, if you have needs, please contact us.
Sorbitan esterand 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.
