The present invention relates to topical compositions in the form of an oil-in-water (O/W) emulsion comprising an oil phase dispersed in an aqueous phase in the presence of a sucrose fatty ester surfactant, characterized in that the topical composition further comprises a phosphate ester co-surfactant. Furthermore, the invention relates to the use of a phosphate ester surfactant to reduce the viscosity of a topical composition in the form of an O/W emulsion comprising an oil phase dispersed in an aqueous phase in the presence of a sucrose fatty ester surfactant.
