II. Application Protocols and Persistence Evaluation

(4) The application protocol was as follows: Shampooing Application of the composition onto wet natural hair Predrying with a hairdryer Blow-drying with a hairdryer

(5) The evaluation protocol after drying relates to the impact on the shape, the cosmetic criteria (feel) and the appearance criteria (TEM visualization, macroscopic effects, static electricity).

(6) The persistence evaluation protocol is as follows: Performance of several cycles: Wetting of the hair Shampooing Rinsing Drying with a hairdryer

(7) The evaluation relates to the impact on the shape, the cosmetic criteria (feel) and the appearance criteria of the locks.

III. Results

(8) The sensorily evaluated locks of hair lead to the following observations:

(9) COMPOSITION A: This coating sensorily gives the head of hair a mass, body and styling effect and also reinforcement at T0 and after shampooing. The shaping is facilitated. The split ends are rewelded together, for up to at least 5 shampoo washes. The working qualities of composition A are good, the product is easy to distribute, and brushing during the heat treatment presents no difficulties. The feel of the dry hair is good, and even after 1 and 5 shampoo washes the product is still perceptible on the fibre (good disentangling on wet and dry hair, good feel, individualized hairs, no tack during the heat treatments). There is no sign of static electricity.

(10) COMPOSITION C: This coating sensorily gives the head of hair a mass, body and styling effect and also reinforcement at T0 and after shampooing. The split ends are rewelded together, for up to at least 5 shampoo washes. However, Copolymer 1 gives rise to a dragging, catching, tack sensation during brushing. Composition C distributes poorly over the head of hair. Dry hair after treatment has an acceptable feel, but this feel once again becomes poor when the hair is moistened and/or shampooed. Disentangling is very difficult. Separation of the individual hairs is observed, which is associated with repellent interactions of static electricity type.

(11) COMPOSITION D: Good working qualities are observed, i.e. good distribution of the composition, easy blow-drying and easy brushing of the hair. After drying, the hair feels good. Moistened and/or shampooed hair is easy to disentangle. However, there is no shaping effect besides a manageability effect. After one shampoo wash, the hair regains its initial feel, and the effects afforded by composition D are no longer perceptible.

II. Application Protocol

(15) Compositions E1, E2, E3, F1, F2 and F3 are applied on weakly sensitized locks of hair (alkaline solubility=20%, SA20), which have been beforehand washed. 0.15 g of composition per gram of locks is applied.

(16) In order to evaluate the persistence of disentangling performance, locks of hair are then washed with a standard shampoo and rinsed.

III. Evaluation and Results

(17) Performances in terms of persistence of disentangling criteria (wet hair) have been evaluated on a scale from 0 (very bad) to 5 (very good):

(18) TABLE-US-00004 Scale Evaluation 0 Very bad 0.5 Very bad/Bad 1 Bad 1.5 Fairly bad/Bad 2 Fairly bad 2.5 Average 3 Fairly good 3.5 Good/Fairly good 4 Good 4.5 Very good/Good 5 Very good

(19) The expert grabs a comb into the locks of hair, from the root to the tip, and evaluates the easiness of passage.

(20) Results are indicated in the tables below:

(21) TABLE-US-00005 E1 (inv) E2 (comp) E3 (comp) After one shampoo 3 1.5 2

(22) TABLE-US-00006 F1 (inv) F2 (comp) F3 (comp) After one shampoo 3 1.5 2

(23) Locks of hair, which have been treated by compositions E1 or F1 according to the invention, have a better disentangling level after one shampoo than locks of hair which have been treated by compositions E2 and E3, or respectively F2 and F3.

(24) As a consequence, the disentangling level after one shampoo has been improved in comparison with the prior art.
