Stable multiple emulsions contain a mixture of emulsifiers consisting of (i) a first, hydrophobic emulsifier (emulsifier A) or several such emulsifiers mixed, having the following properties: it must be highly soluble in the oil phase of the emulsion at the manufacturing temperature of the emulsion; it may not be isotropically soluble in water below approximately 50 DEG ; it may be isotropically soluble in the water at temperatures between approximately 50 DEG and the manufacturing temperature of the emulsion; it must act primarily as a W/O emulsifier at temperatures between approximately 50 DEG and the manufacturing temperature of the emulsion; and (ii) a second, hydrophilic emulsifier (emulsifier B) or several such emulsifiers mixed, having the following properties: it must be isotropically soluble in water; its solubility at temperatures between approximately 50 DEG and the manufacturing temperature of the emulsion must be substantially stable.
