Disclosed herein are novel block polymers comprising at least one first block and at least one second block, wherein the at least one first block comprises at least one acrylate monomer of formula CH2═CH—COOR2 wherein R2 is chosen from C4 to C12 cycloalkyl groups and at least one methacrylate monomer of formula CH2═C(CH3)—COOR′2 wherein R′2 is chosen from C4 to C12 cycloalkyl groups, and the second block comprises at least one acrylic acid monomer and at least one monomer with a glass transition temperature of less than or equal to 20° C. Also disclosed herein is a process for the preparation of such polymers which may be carried out continuously in a single reactor. Finally, further disclosed herein are compositions comprising the novel polymers and processes using the composition for making up and/or caring for keratinous substances or for improving the hold of a cosmetic composition while maintaining its gloss.
摘要:
The present invention relates to novel block polymers comprising at least one first block and at least one second block that are incompatible with each other, have different glass transition temperatures (Tg), and are linked together via an intermediate segment 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. The block polymer has a polydispersity index I of greater than 2. The invention also relates to cosmetic compositions comprising the block polymers and processes for their use.
摘要:
Composition for coating keratin fibres with a high dry extract comprising a block polymer A subject of the invention is a composition for coating keratin fibres comprising, in a cosmetically acceptable medium, a block polymer, a styrene-free block polymer, the said composition having a dry matter or dry extract content of greater than or equal to 45% by weight. A subject of the invention is also the use of such a composition for obtaining a makeup for the keratin fibres, in particular the eyelashes, which is charging and/or homogeneous and/or smooth and/or has good staying power.
