Sorbitan esters are nonionic lipophilic surfactants that are commonly used as water-in-oil (W/O) emulsifiers and stabilizers. Sorbitan fatty acid esters are produced by esterification of dehydrated sorbitol (sorbitan) with a variety of fatty acids. Sorbitol is a sugar alcohol that can be obtained by the reduction of glucose or derived from corn, potatoes, etc. The fatty acids commonly used to synthesize sorbitan esters include lauric acid, palmitic acid, stearic acid, and oleic acid.
As sorbitan esters have numerous functions, our range of surfactants is used in a variety of settings, for example, as an emulsifier in food, a stabilizer in a cosmetic cream formulation, or a cosolvent and antirust agent for petroleum and oil. These surfactants are sourced from vegetables and vegan friendly. They are safe and nontoxic as food additives when used according to regulations.
Our range of sorbitan esters has a hydrophilic-lipophilic balance (HLB) between 1.6 - 8.6, which make them dissolvable in polar organic solvents and oils. When used in combination with varying proportions of ethoxylated sorbitan esters (polysorbate) that have an HLB range between 10.0 – 16.7, it creates more versatile surfactants; which can produce W/O or oil-in-water (O/W) emulsions with varying levels of consistencies, expanding the possible applications of these surfactants.
