In one embodiment of the present invention, before and / or after the method according to the present invention, a shampooing step is carried out on the keratin fibers an optional number of times. Also, another step of conditioning the keratin fibers may be carried out in combination with the method according to the present invention.

[0192] The keratin fibers treated by the method according to the present invention may be wet or dry. In a preferred embodiment of the present invention, when the method according to the present invention is carried out, the keratin fibers are wet. Therefore, the method according to the present invention can be applied to wet hair.

[0193] After applying the composition, the keratin fibers may be left standing for a certain length of time, as needed, typically from 1 second to 10 minutes, preferably 5 seconds to 5 minutes, and more preferably 10 seconds to 3 minutes, to allow the composition to penetrate the keratin fibers.

[0194] The method according to the present invention may further include a step of rinsing the composition off the keratin fibers after the application step. In one embodiment of the present invention, the keratin fibers are rinsed with water to rinse off the applied composition from the keratin fibers. [Examples]

[0195] The present invention will be described in more detail by reference to examples. However, these examples should not be construed as limiting the scope of the present invention. The following examples are presented as non-limiting illustrations in the art of the present invention.

[0196] [Composition] Each of the compositions from Examples 1-3 (Ex.1-Ex.3) and Comparative Examples 1-5 (Comp.Ex.1-Comp.Ex.5) was prepared by mixing the components listed in Table 1 below. All numerical values ​​regarding the amount of components are based on the "mass%" of the active raw materials. All compositions had a pH value of 4.

[0197] [evaluation] (Sensory evaluation) Bleached hair (Chinese, 2.7g, 27cm) was washed with plain shampoo and then rinsed. Subsequently, 0.4g / 1g of each composition from Examples 1-3 and Comparative Examples 1-5 was applied to the bleached hair, and their sensory properties, i.e., the feeling of coating upon application, were evaluated.

[0198] After letting the hair stand for 5 minutes, the composition was rinsed with water, and then the excess water was removed by squeezing twice with fingers. The treated wet hair was then prepared as a sample for sensory evaluation of its detangle-free properties on wet hair.

[0199] The conditioning attributes were evaluated by three experimental experts based on the following criteria. Coating feeling upon application 1: Smooth 2: Somewhat not smooth 3: Not smooth Tangling resolution 1: Very easy 2: Easy 3: Somewhat easy 4: Somewhat not easy 5: Not easy

[0200] The scores were averaged and shown in Table 1. A lower overall score indicates that a higher quality coating is perceived.

[0201] (Measurement of combing force) The bleached hair (Chinese, 2.7 g, 27 cm) was washed using a plain shampoo and then rinsed. Subsequently, 0.4 g / hair 1 g of each composition according to Examples 1 to 3 and Comparative Examples 1 to 5 was applied to the bleached hair. After leaving the hair standing for 5 minutes, the composition was rinsed with water and then squeezed twice with fingers to remove excess water. Then, the measurement of the combing force was performed on the wet hair.

[0202] The treated wet hair was combed once from the root to the tip starting from a point 2.5 cm from the root with a fine-tooth comb, and simultaneously the combing force was recorded using DIA-STRON MTT175 and SILKOMB PRO-30. The average combing force in the middle of the hair bundle (a portion 15 cm to 17.5 cm away from the root) was calculated as the representative combing force.

[0203] The results are shown in Table 1.

[0204]

Table 1

[0205] As shown in Table 1, the composition according to the present invention was able to provide the hair with improved cosmetic effects in terms of a smooth coating feel upon application and detangling of wet hair. In addition, the composition according to the present invention provided a lower combing force to wet hair, which resulted in improved smoothness and detangling of the hair. Accordingly, it can be said that the composition according to the present invention was able to provide the hair with improved smoothing and detangling properties.

[0206] On the other hand, Comparative Examples 1 to 3, which did not contain (b) the solid fatty acid ester of the present invention, and Comparative Examples 4 and 5, which did not contain (c) the aliphatic dicarboxylic acid of the present invention, were unable to provide sufficient smoothing and detangling effects to the hair from the application stage.

[0207] Therefore, it can be concluded that the composition according to the present invention is highly preferable for conditioning keratin fibers.
