[0160] For the purposes of this invention, the expression "conditioning keratin fibers" refers to conditioning keratin fibers by providing beauty effects to hair, such as imparting smoothness to the keratin fibers, and does not refer to washing the keratin fibers, such as by washing them with shampoo. Therefore, the method according to the present invention is different from a method for washing keratin fibers or a method for washing keratin fibers such as hair with shampoo.

[0161] In one embodiment of the present invention, the method does not include the step of washing and / or shampooing keratin fibers such as hair.

[0162] The step of applying the composition to keratin fibers can be carried out by any means. For example, the application can be done by hand or using any applicator (such as a comb or brush).

[0163] Components (a) and (b) are as described above. In addition, the composition may contain additional optional components as described above.

[0164] The step of applying the composition can be carried out after the shampooing and rinsing steps of the keratin fibers. In one embodiment of the present invention, the keratin fibers are shampooed a number of times of any choice before and / or after the method according to the present invention. Alternatively, another step of conditioning the keratin fibers may be carried out in combination with the method according to the present invention.

[0165] 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, the keratin fibers are wet when the method according to the present invention is carried out. Therefore, the method according to the present invention can be applied to wet hair.

[0166] After applying the composition, the keratin fibers may be left undisturbed for a specific length of time, 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.

[0167] 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]

[0168] 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.

[0169] [Composition] Each of the compositions from Examples 1-7 (Ex.1-Ex.7) and Comparative Examples 1-7 (Comp.Ex.1-Comp.Ex.7) was prepared by mixing the components listed in Tables 1 and 2 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. The "mass ratio [cat / amp]" indicates the mass ratio of the total amount of cationic surfactant to the total amount of amphoteric surfactant.

[0170] [evaluation] (Sensory evaluation) Bleached hair (Chinese, 2.7g, 27cm) was washed with plain shampoo and then rinsed. Then, to evaluate the instantaneous penetration, 0.4g / 1g of each composition from Examples 1-7 and Comparative Examples 1-7 was applied to the bleached hair.

[0171] After letting the hair stand for 5 minutes, the composition was rinsed with water, then squeezed twice with fingers to remove excess water, and the treated wet hair was prepared as a sample for evaluating the smoothness of the wet hair.

[0172] Conditioning attributes were evaluated by three experimental experts based on the following criteria.

[0173] Instant absorption upon application. 1: Very comfortable 2: Comfortable 3: Somewhat unpleasant 4: Unpleasant Smoothness 1: Very smooth 2: Smooth 3: Slightly not smooth 4: Not smooth

[0174] The scores were averaged and shown in Tables 1 and 2. A lower overall score indicates a perceived higher quality coating effect.

[0175] (Measurement of combing force) Bleached hair (Chinese, 1g, 27cm) was washed with plain shampoo and then rinsed. Then, 0.4g / 1g of each composition from Examples 1-7 and Comparative Examples 1-7 was applied to the bleached hair. After letting the hair stand for 5 minutes, combing strength was measured on wet hair before rinsing off the composition.

[0176] The treated wet hair was combed twice using a fine-toothed comb, starting 2.5 cm from the roots and going to the tips. Simultaneously, the combing force was recorded using a DIA-STRON MTT175 and a SILKOMB PRO-30 comb. The average combing force in the middle of the hair strand (5 cm to 15 cm from the roots) was calculated as the representative combing force. The second combing force is shown in Table 1 and Table 2. The second combing force represents the combing force after the first combing, and reflects the combability of the hair strand after it has been straightened by the first combing.

[0177] The results are shown in Table 1 and Table 2.

[0178] [Table 1]

[0179] [Table 2]

[0180] As shown in Table 1 and Table 2, each composition according to Examples 1 to 7, which contained components (a) and (b) and satisfied a specific range of ratios of the amounts of the total cationic surfactant and the total amphoteric surfactant, was able to impart improved cosmetic effects to the hair with respect to an instantaneous feeling of penetration, low combing force during application, and smoothness of wet hair. Accordingly, it can be said that the composition according to the present invention was able to impart a conditioning effect with improved smoothing characteristics to the hair from the application stage.

[0181] On the other hand, each composition according to Comparative Examples 1 to 6, which did not contain component (a) or (b) or did not satisfy a specific range of ratios of the amounts of the total cationic surfactant and the total amphoteric surfactant, was unable to impart a sufficient conditioning effect to the hair.

[0182] Also, as shown in Table 1 and Table 2, each composition according to Examples 2, 4, and 5, which contained components (a) and (b), was able to impart improved cosmetic effects to the hair with respect to an instantaneous feeling of penetration, low combing force during application, and smoothness of wet hair, as compared with the composition according to Comparative Example 5 in which a betaine-type surfactant was used instead of the (b) amino acid-type amphoteric surfactant, even though the ratios of the amounts of the total cationic surfactant and the total amphoteric surfactant contained therein were the same. Accordingly, it can be said that the composition according to the present invention, which uses at least one amino acid-type amphoteric surfactant as (b), was able to impart a conditioning effect with improved smoothing characteristics to the hair from the application stage.

[0183] Therefore, it can be concluded that the composition according to the present invention is highly preferable for conditioning keratin fibers.
