[0168] II. Procedure

[0169] 2.1. ProcedureApplication to the Locks

[0170] The compositions described in the table above are applied to locks 1 to 9 on each side with a brush.

[0171] Locks 1 to 6 are heated for a time of 30 minutes at a temperature of 50 C. and lock 7 is heated for a time of one hour at a temperature of 50 C. on a hotplate in a closed heating bag.

[0172] A straightening iron is then applied to each of the locks 1 to 6 by making continuous passes along the locks.

[0173] The locks are left to stand at room temperature for a time of 24 hours before performing a first sensory evaluation of the disentangling (measurement TO).

[0174] Lock 8 is placed under the exposure of a UV lamp (=365 nm, 100 Watts) for 5 minutes, then the lock is left to stand at room temperature for a time of 24 hours before performing a first sensory evaluation of the disentangling (measurement T0).

[0175] Lock 9 is placed under the exposure of a LED lamp (17 Watts) for 10 minutes on each side, then the lock is left to stand at room temperature for a time of 24 hours before performing a first sensory evaluation of the disentangling (measurement T0).

[0176] 2.2. Evaluation of the Feel and of the Disentangling

[0177] After drying, disentangling tests with a comb were performed after immersion for 10 seconds in water, by passing a plastic comb through five times.

[0178] 2.3. ProcedureShampoo Resistance

[0179] Shampoo is applied to each of the locks, at a rate of 1 g per 2.8 g of locks, and the locks are then massaged for a time of 10 seconds. The shampoo is left on for a time of 3 minutes, before rinsing with water at a temperature of 37 C., 10 passes being performed. The lock is then dried.

[0180] This protocol is repeated five times and a second sensory evaluation of the disentangling is performed (measurement T5).

TABLE-US-00002 T0 T5 Locks Disentangling Disentangling 1 2 + 3 + 4 ++ ++ 5 ++ ++ 6 ++ ++ 7 + ++ 8 ++ + 9 ++ ++

[0181] It is found that the compositions according to the invention lead to an improvement in the disentangling.
