Capmul products are mono-, di- and triglyceride emulsifiers prepared through the glycerolysis of select fats and oils. They can be prepared by esterification of glycerin with specific fatty acids. They are lipophilic, insoluble in water and soluble in oils at elevated temperatures. They are used to produce stable emulsions and to modify viscosity. Capmul MCM has excellent solvent properties.
Caprol® polyglycerol esters (PGE’s) are generally prepared by esterification of select polyglycerol molecules with fatty acids or by alcoholysis of a vegetable oil with a polyglycerol. Their wide HLB range make them suitable for both w/o and o/w systems. PGE molecular weights vary from low to high and their form at room temperature ranges from a viscous liquid to a brittle solid. PGE’s are also useful as emulsifiers, foaming agents, solubilizers, clouding agents, crystallization inhibitors, glossers and suspending agents. They prevent agglomeration in several cosmetic applications including physical sun screen agents.
