Abstract:
1. A cosmetic composition comprising, in a cosmetically acceptable organic liquid medium, at least one block polymer and at least one plasticizer, wherein: the at least one block polymer has a polydispersity index I of greater than 2 and is a film-forming linear ethylenic polymer devoid of styrene; the at least one plasticizer is a compound, the nature and the amount of which allow the cosmetic composition to form a film having a hardness of less than or equal to 35 seconds, the hardness of the film being measured using a Persoz pendulum according to the December 1991 version of Standard NF-T-30-016; and the at least one block polymer comprises at least one first block and at least one second block having different glass transition temperatures (Tg), wherein the at least one first block and the at least one second block are connected to one another 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, and further wherein said intermediate block is a random copolymer block.
