Abstract
The invention relates to fine emulsions comprising at least one W/O emulsifier and at least one hydrophilic component, and to a process for their preparation. The fine emulsions are obtainable by converting a W/O preemulsion comprising at least one W/O emulsifier into an O/W fine emulsion by adding at least one hydrophilic component and, where appropriate, changing the temperature. Suitable W/O emulsifiers are preferably sorbitol esters. The fine emulsions are preferably spray emulsions for cosmetic and pharmaceutical applications.
