Inverse latices self-invertible with respect to white mineral oils, squalane, hydrogenated polyisobutene, isohexadecane or isododecane and cosmetic, democosmetic, dermopharmaceutical or pharmaceutical compositions comprising them

A composition, comprising:

• an oil phase, an aqueous phase, at least one emulsifying agent of water-in-oil (W/O) type and at least one emulsifying agent of oil-in-water (O/W) type in the form of a self-invertible inverse latex comprising from 20% to 70% by weight of a branched or crosslinked polyelectrolyte, wherein
• a constituent solvent of the oil phase is selected from the group consisting of squalane and hydrogenated polyisobutene, and the polyelectrolyte is selected from the group, consisting of a homopolymer based on a monomer having a partially or completely salified strong acid functional group and a copolymer based on at least one monomer having a partially or completely salified strong acid functional group copolymerized with acrylamide with a crosslinking and/or branching agent of diallyloxyacetic acid or one of its salts;
• or
• the constituent solvent of the oil phase is selected from the group consisting of white mineral oils, isohexadecane, and isododecane, and the polyelectrolyte is a copolymer based on at least one monomer having a partially or completely salified strong acid functional group copolymerized with acrylamide with the crosslinking and/or branching agent being triallylamine.
