摘要：
The invention relates to an oil-in-water emulsion including, for 100% of the weight thereof: 5 to 55 wt % of an oil phase (P1) consisting of at least one oil and/or at least one wax； 0.06 to 4.5 wt % of at least one cross-linked anionic polyelectrolyte resulting from the polymerization of at least one monomer having a strong acid function, said monomer being partially or totally salified 2-methyl 2-[(1-oxo 2-propenyl) amino] 1-propanesulfonic acid, with at least one neutral monomer selected from the N,N-dialkyl acrylamides, wherein each of the alkyl groups comprise between one and four carbon atoms, and at least one monomer of formula (I), where R is a straight or branched alkyl radical comprising eight to twenty carbon atoms and n is a number no smaller than one and no larger than twenty, in the presence of at least one cross-linking agent； and 0.0025 to 1 wt % of xanthan gum (GX)； 0.0025 to 1 wt % acacia gum (GA)； 38.5 to 94.835 wt % of a cosmetically acceptable aqueous phase (P2), said aqueous phase (P) including, for 100% of the weight thereof, 1 to 10 wt % of at least one dissolved salt (S), and said composition (C1) being further characterized in that the weight ratio between the xanthan gum (GX) and the acacia gum (GA) is greater no less than 1/3 and no greater than 3/1. The invention also relates to the method for preparing such compositions, and to the use thereof in cosmetics.Emulsion de type huile-dans-eau, comprenant pour 100% de sa masse: - de 5% à 55% massique d'une phase grasse (P1) constituée d'au moins une huile et/ou d'au moins une cire, - de 0,06% à 4,5% massique d'au moins un polyélectrolyte anionique réticulé (PA) issu de la polymérisation d'au moins un monomère possédant une fonction acide fort, ledit monomère étant l'acide 2-méthyl 2-[(1-oxo 2-propènyl) amino] 1-propanesulfoniquepartiellement ou totalement salifiée, avec au moins un monomère neutre choisi parmi les N,N-dialkyl acrylamides, dans lesquels chacun des groupes alkyle comportent ent
