Abstract: Sucrose esters such as sucrose laurate and sucrose dilaurate are notoriously difficult to emulsify in an oil-in-water emulsion and tend to destabilize these types of emulsions. It has now been found that combining a sucrose ester with certain hydrophobically modified aqueous rheology modifier and non-ionic stearic acid derivative emulsifiers can greatly improve emulsion stability.
