<p>Composition (I), comprises: ethylenic block copolymers, containing at least one first block having a glass transition temperature (Tg) >= 40[deg] C and being derived wholly or partly from first monomers, and at least one second block having a glass transition temperature = 20[deg] C and being derived wholly or partly from second monomers; siloxane resin comprising siloxane units (a)-(d); and volatile solvents. Composition (I), comprises: ethylenic block copolymers, containing at least one first block having a glass transition temperature (Tg) >= 40[deg] C and being derived wholly or partly from first monomers, which are such that the homopolymer prepared from these monomers has a glass transition temperature >= 40[deg] C, and at least one second block having a glass transition temperature = 20[deg] C and being derived wholly or partly from second monomers, which are such that the homopolymer prepared from these monomers has a glass transition temperature = 20[deg] C, where the first block and the second block is joined together by a random intermediate segment comprising at least one of the first monomers constituting the first block and at least one of the second monomers constituting the second block, and the block copolymer has a polydispersity index (I) greater than 2; siloxane resin comprising siloxane units of formula (((R 1>) 3SiO 1/2) a) (a), (((R 2>) 2SiO 2/2) b) (b), ((R 3>SiO 3/2) c) (c) and ((SiO 4/2) d) (d); and volatile solvents, where the weight ratio of the volatile solvent to the ethylenic block copolymer is greater than 2. Either: a : 0.05-0.5; and b : 0-0.3; or c : greater than zero; or d : 0.05-0.6; or a + b + c + d : 1, where more than 40 mol.% of the groups R 3>of the siloxane resin are propyl groups; and R 1>-R 3>1-8C alkyl, aryl, 1-8C carbinol or amino. An independent claim is also included for method for treating keratin fibers comprising the application of (I) on the keratin fibers, optionally followed by drying at temperature above 40[deg] C.</p> |
