Abstract

Procedure for preparing a stable emulsion, characterized in that it comprises a hydrophobic oil phase and an aqueous phase, and in which the hydrophobic oil phase is made up of cholesteric liquid crystalline materials, while the aqueous part is made up of preferably proteinic film-forming colloids. and especially gelatin, whose aqueous and oily phases are prepared independently, by hot dispersion of their respective materials, before homogeneously joining to form the stable emulsion.
