The invention provides high molecular weight polymers used in small amounts as viscosity modifiers for aqueous/aqueous biphasic liquids. The viscosity of the biphasic is enhanced at least 20 %, preferably at least 30 % relative to same compositions without use of polymer. Further, the polymer is included without destroying the ability of dual phase compositions to form after product is left standing.
L'invention concerne l'utilisation de faibles quantités de polymères de poids moléculaire élevé pour modifier la viscosité de liquides biphasés aqueux/aqueux. L'invention permet d'améliorer la viscosité de la biphase d'au moins 20 %, de préférence d'au moins 30 %, par rapport aux mêmes compositions sans utilisation du polymère. En outre, l'inclusion du polymère ne détruit pas la capacité des compositions à se reformer en double phase après que le produit ait reposé un certain temps.
