Abstract Stable multiple emulsions, containing an emul- sifier mixture comprising - a first, hydrophobic emulsifier (emulsifier A), or a mixture of several such emulsifiers, having the following properties: - it must be very readily soluble in the oil phase of the emulsion at the preparation temperature of the emulsion - it must not be soluble in water to give an isotropic solution below approximately 50° - it must be soluble in water to give an isotropic solution in the temperature range between approximately 50° to the preparation temperature of the emulsion and - it must act primarily as a w/o emulsifier in the temperature range between approximately 50° to the preparation temperature of the emulsion - and a second, hydrophilic emulsifier (emulsifier B), or a mixture of several such emulsifiers, having the following properties: - it must be soluble in water to give an isotropic solution - its solubility in the temperature range between approximately 50° to the preparation temperature of the emulsion must be essen- tially stable.
