Example 1

[0287] Compositions A1, A2 and A3 according to the invention and comparative composition B1, as described in Table 1 below, were prepared. The amounts are expressed as grams of active material/100 g.

[0288] The turbidity was then evaluated. The measurements were taken with a Hach 2100P model portable turbidimeter. The values are given in NTU at 25? C. The higher the value, the more opaque the sample.

[0289] The results obtained are collated in Table 2 below.

TABLE-US-00002 TABLE 2 Compositions A1 A2 B1 Turbidity value at 25? C. (NTU) 13.2 4.4 17.9

[0290] Compositions A1 and A2 according to the invention have low turbidity values, lower than that of the comparative composition B1.

[0291] Thus, the compositions according to the invention are more transparent than the comparative composition B1.

[0292] Moreover, compositions A1 and B1 were applied per half-head on a panel of eight people, at a rate of 6 g of composition per half-head.

[0293] The cosmetic performance qualities, notably in terms of suppleness and smoothness of feel, were evaluated at different times of use of the compositions.

[0294] It was found that: [0295] when the composition is applied to the hair, composition A1 according to the invention gives results that are superior to those given by the comparative composition B1, in terms of suppleness (the smooth feel is not evaluated); [0296] when the composition is rinsed off, composition A1 according to the invention gives results that are superior to those given by the comparative composition B1, in terms of suppleness and smoothness of feel; [0297] on damp hair (before drying), composition A1 according to the invention gives results that are superior to those given by the comparative composition B1, in terms of suppleness and smoothness of feel; [0298] on dried hair, composition A1 according to the invention gives results that are superior to those given by the comparative composition B1, in terms of suppleness and smoothness of feel; it was also found that there is better coating of the hair, better strand separation and also better visual smoothness with the invention.
