According to the present invention there is provided composition in the form of an oil-in-water emulsion having a viscosity of between 15,000 cP and 45,000 cP at 23 °C, having a pH of between 2 and 6 and comprising: (i) at least 1.6% of at least one cross-linked anionic polyelectrolyte resulting from the polymerisation of partially or completely salified 2-methyl 2-[(1-oxo 2-propenyl)amino] 1-propane sulfonic acid, with at least one neutral monomer chosen from the N,N-dialkyl acrylamides, wherein each of the alkyl groups comprises between one and four carbon atoms, and at least one monomer of formula (B):wherein R represents a linear or branched alkyl radical comprising eight to twenty carbon atoms and n represents a number greater than or equal to one and less than or equal to twenty, in the presence of at least one cross-linking agent； (ii) at least 4% of at least one polysorbate； (iii) at least 0.1% of at least one polysaccharide gum； and (iv) between 6% and 30% water.The present invention also provides a composition as defined above obtainable by a process comprising the following steps: (a) in one vessel, homogenising the polysaccharide gum (iii) into the aqueous phase comprising the water at a temperature of between 60 °C and 90 °C； (b) in a vessel separate from that in (a), homogenising the cross-linked anionic polyelectrolyte (i) and the polysorbate (ii) into the oil phase at a temperature of between 60 °C and 90 °C； and (c) combining the ingredients of (a) with the ingredients of (b) through homogenisation at a temperature of between 60 °C and 90 °C.
