Abstract
The present invention describes stable water-in-oil emulsions comprising the following components: water, oil, a labile compound of interest, a stabilizing agent and an emulsifier. The labile compound present in the water phase is stabilized by addition of a stabilizing agent which preferably is a polyol. Specific emulsifiers are described which give rise to stable emulsions in the presence of high amounts of a polyol.
