Abstract:
1. A cosmetic composition comprising at least one block polymer and a cosmetically acceptable organic liquid medium comprising a non-volatile liquid fatty phase, wherein: the at least one block polymer is chosen from film-forming linear ethylenic polymers, has a polydispersity index of greater than or equal to 2.5, and comprises at least one first block and at least one second block with different glass transition temperatures (Tg) connected together via an intermediate block comprising at least one constituent monomer of the at least one first block and at least one constituent monomer of the at least one second block, wherein the at least one constituent monomer of the at least one first block differs from the at least one constituent monomer of the at least one second block, said intermediate block is a random copolymer block, and the at least one first block of the polymer is chosen from: a) a block with a Tg of greater than or equal to 40° C., b) a block with a Tg of less than or equal to 20° C., c) a block with a Tg of between 20 and 40° C., and the at least one second block is chosen from a category a), b) or c) different from the at least one first block, the non-volatile liquid fatty phase comprises at least 30% by weight of at least one non-volatile silicone oil, relative to the total weight of the non-volatile liquid fatty phase, and the at least one block polymer is non-elastomeric.
