Sorbitan Stearate (Sorbitan Monostearate) is an ester of sorbitan with Stearic acid, an excellent water-in-oil emulsifier with an HLB value of 4.7. It is also known under the trade name Crill 3 NF.
Combined with polysorbates (polyoxyethylene sorbitan fatty acid esters), Sorbitan Stearate is also an effective co-emulsifier in oil-in-water systems. Manipulation of their ratio yields emulsifying systems of various HLB values, allowing for the emulsification of many cosmetic and pharmaceutical ingredients.
In addition, Sorbitan Stearate is used as a solubilizing agent. It is listed in 21CFR 172.842 2 for use as a multi-purpose food additive. So, it is a safe ingredient for skin care applications.
