摘要：
The invention relates to a composition (C1) in the form of an oil-in-water emulsion, including, for 100% of the weight thereof: 5 to 55 wt % of an oil phase (Pl) 0.025 to 3.75 wt % of at least one cross-linked anionic polyelectrolyte (PA) resulting from the polymerization of partially or completely salified 2-methyl 2-[(1-oxo 2-propenyl) amino] 1-propanesulfonic acid, with at least one neutral monomer selected from acrylamide, (2-hydroxy ethyl) acrylate, and N,N-dialkyl arylamides, wherein each of the alkyl groups comprise between one and four carbon atoms, and at least one monomer of formula (I), where R is an 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 a cross-linking agent 0.025 to 3.75 wt % of a galactomannan (GM) having a degree of substitution (DS) of approximately 1/3 37.5 to 94.95 wt % of a cosmetically acceptable aqueous phase (P2), said aqueous phase (P2) including, for 100% of the weight thereof, 1 to 25 wt % of a salt (S), the weight ratio between the galactomannan (GM) and the cross-linked anionic polyelectrolyte being no less than to 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.Composition (C1) se présentant sous la forme dune émulsion de type huile-dans-eau, comprenant pour 100% de sa masse: - De 5% à 55% massique dune phase grasse (P1) - De 0,025% à 3,75% massique dau moins un polyélectrolyte anionique réticulé (PA) issu de la polymérisation de lacide 2-méthyl 2-[(1-oxo 2-propènyl) amino] 1-propanesulfonique partiellement ou totalement salifiée, avec au moins un monomère neutre choisi parmi lacrylamide, lacrylate de (2-hydroxy éthyle), les N,N-dialkyl acrylamides, dans lesquels chacun des groupes alkyle comportent entre un et quatre atomes de carbones, et au moins un monomère de formule (I) : dans laquelle R représente un radical alkyle comportant de huit à vingt at
