[0195] Therefore, if step (ii) is present, the keratin fibers are rinsed to remove the composition according to the present invention from the keratin fibers. The rinsing step may be carried out with water. The keratin fibers are preferably dried after rinsing. Drying of the keratin fibers can be carried out by conventional drying means such as a hair dryer.

Examples

[0202] The present invention will be described in more detail by way of examples. However, these examples should not be construed as limiting the scope of the present invention.

[0203] (Examples 1 to 3 and Comparative Examples 1 to 3) [Preparation] Each of the compositions according to Examples 1 to 3 and Comparative Examples 1 to 3 was prepared by mixing the components shown in Table 1. The components other than water and the moisture shown in Table 1 were mixed at 80°C to form an emulsion. Then, the emulsion was cooled to room temperature, and thereafter, the remaining water was added to the emulsion. All numerical values regarding the amounts of the components are based on the "mass%" of the active substance.

[0206] [Evaluation] (Coefficient of friction) All the bleached hair samples (1 g, 27 cm) were washed once with shampoo. After shampooing, the hair samples were rinsed with water and dried. Then, 0.4 g of each of the compositions according to Examples 1 to 3 and Comparative Examples 1 to 3 was applied onto each hair sample and dried with a hair dryer.

[0207] The coefficient of friction of the dried hair sample was measured using a Handy Rub Tester TL 701 manufactured by Trinity-Lab Inc.

[0208] The results are shown in Table 1 above.

[0209] The compositions according to Examples 1 to 3 containing stearamidopropyldimethylamine, distearoylethyldimonium chloride, and sucrose esters (sucrose laurate, sucrose palmitate, sucrose stearate) show lower values than the compositions according to Comparative Examples 1 to 3 that do not contain all three components. This indicates that the compositions having stearamidopropyldimethylamine, distearoylethyldimonium chloride, and sucrose esters improve smoothness.

[0210] (Sensory analysis 1) All the bleached hair samples (2.7 g, 27 cm) were treated once with shampoo. After shampooing, the hair samples were rinsed with water and dried. Then, 1.0 g of each of the compositions according to Example 1 and Comparative Examples 1 to 3 was applied onto each hair sample and dried with a hair dryer.

[0211] A sensory test was conducted to evaluate the smoothness, coating feeling, and flexibility of the hair fibers by comparing the hair samples treated with the compositions according to Example 1 and Comparative Examples 2 to 3 with the hair samples treated with the composition according to Comparative Example 1 standardized as 0. The relative scores for the smoothness, coating feeling, and flexibility of the hair fibers were averaged among 4 panelists. A higher score indicates smoother, more coated, and more flexible hair fibers.

[0212] The results are shown in Table 2 below.

[0213]

Table 2

[0214] (a) The composition according to Example 1 containing a fatty amine (stearamidopropyldimethylamine), (b) an esterquat (distearoylethyldimonium chloride), and (c) a sucrose ester (sucrose laurate) shows higher values than the compositions according to Comparative Examples 1 to 3 that do not contain all three components. This indicates that the composition having (a) a fatty amine, (b) an esterquat, and (c) a sucrose ester improves the smoothness, coating feeling, and flexibility of hair fibers.

[0215] (Sensory analysis 2) All the bleached hair samples (2.7 g, 27 cm) were treated once with shampoo. After shampooing, the hair samples were rinsed with water and dried. Then, 1.0 g of each of the compositions according to Examples 1 to 3 was applied onto each hair sample and dried with a hair dryer.

[0216] A sensory test was conducted to evaluate the smoothness, coating feeling, and flexibility of hair fibers by comparing the hair samples treated with the compositions according to Examples 2 and 3 with the hair samples treated with the composition according to Example 1 standardized as 0. The relative scores for the smoothness, coating feeling, and flexibility of hair fibers were averaged among four panelists. A higher score indicates smoother, more coating-feeling, and more flexible hair fibers.

[0217] The results are shown in Table 3 below.

[0218]

Table 3

[0219] (a) Fatty amine (stearamidopropyldimethylamine), (b) esterquat (distearoylethyldimonium chloride), and (c) sucrose ester (sucrose palmitate or sucrose stearate, different from sucrose laurate) in the compositions according to Examples 2 to 3 show substantially the same results as the composition according to Example 1 containing (a) fatty amine (stearamidopropyldimethylamine), (b) esterquat (distearoylethyldimonium chloride), and sucrose laurate. This indicates that the compositions having (a) fatty amine, (b) esterquat, and (c) sucrose ester achieve a comparable level of smoothness, coating feel, and flexibility regardless of the type of (c) sucrose ester used.
