A fluid cosmetic composition having unusual rheological properties has a formulation comprising 0.1 to 50% by weight of at least one fluid branched polymer obtained by the simultaneous reaction of components A, B and C wherein A is a linear polymer having a molecular weight MW of between 5000 and 50000 Da, B is a linear polymer having a molecular weight MW of between 5000 and 5000 Da, and C is a linear polymer having a molecular weight MW of between 5000 and 5000 Da. A is a reactive functional group X provided on the chain at a concentration of between 0.1 and 50 mmol/g polymer, B is a linear polymer having a molecular weight MW of between 10000 and 100000 Da, a terminal reactive functional group having the Y type, capable of reacting with said functional group X in an addition or condensation reaction, and C is a molecule or linear oligomer having a molecular weight of between 50 and 1000 Da (or a mixture thereof), capable of reacting with said functional group X in an addition or condensation reaction.
