Abstract
The present invention deals with novel emulsifiers. The compounds are esters made by the reaction of sorbitol and meadowfoam acids. The introduction of the unsaturated highly stable meadowfoam acid portion of the molecule into the compounds of the present invention results in improved emulsification efficiency, improved oxidative stability and improved liquidity of the esters.
