ABSTRACT:
An emulsifier composition including an ester selected from the group consisting of: pentaerythritol, dipentaerythritol, tripentaerythritol, and mixtures thereof; at least one alkoxylated nonionic emulsifier; and less than 10% by weight water, where partial glycerides may be present in an amount of less than 10% by weight, based on the amount of component (a) present in the composition, is provided. A process for the production of an emulsion, including dispersing the emulsifier composition in an oil phase; heating the emulsifier composition dispersed in the oil phase to a temperature above the phase inversion temperature thereof; heating an aqueous phase to a temperature above the phase inversion temperature thereof; and stirring the oil phase with the aqueous phase and cooling to room temperature is also provided. A cosmetic composition including the emulsifier composition is also provided.
