| 1. A process for the preparation of a composition in a liquid form at ambient temperature consisting of a fatty external phase
and a gelled aqueous internal phase representing about 60% up to about 98% by weight of said composition, said process consisting
of the steps of:
preparing a fatty phase;
preparing a gelled aqueous phase;
adding said fatty phase to said gelled aqueous phase, said gelled aqueous phase being about 60% to about 98% by weight of
said added phases; and
modifying said added phases to form a water-in-oil emulsion in a liquid form at ambient temperature consisting of said fatty
phase as the external phase and of said gelled aqueous as the internal phase, wherein,
said gelled aqueous phase comprises a polyelectrolyte polymer, water, and optionally one or more sunscreens, and
said fatty phase comprises one or more oils, a lipophilic emulsifying system comprising one or more emulsifying surfactants,
and optionally one or more sunscreens.
