Therefore, the composition according to the present invention is as described in the method described above. (a) at least one fatty amine, (b) at least one amino acid-type amphoteric surfactant, and (c) at least one aliphatic dicarboxylic acid Includes.

[0137] For the purposes of this invention, the expression "conditioning keratin fibers" refers to conditioning keratin fibers by providing beauty effects to the hair, such as coating the keratin fibers, and does not refer to cleaning the keratin fibers, for example, by shampooing. Therefore, the composition according to the present invention is different from a composition for cleaning keratin fibers, such as a shampoo composition.

[0138] Components (a) to (c) are as described above. In addition, the composition according to the present invention may contain additional optional components as described above.

[0139] The compositions according to the present invention are for conditioning keratin fibers, preferably hair. Therefore, the compositions according to the present invention may be topical compositions intended for application to keratin fibers.

[0140] The composition according to the present invention may be of the leave-on type or the rinse-off type. The leave-on type composition is not rinsed off after use on keratin fibers. The rinse-off type composition is rinsed off after use on keratin fibers.

[0141] The composition according to the present invention can be used to condition keratin fibers. Preferably, the composition according to the present invention can be used as a hair treatment or conditioner for hair.

[0142] The composition according to the present invention contains (a) a fatty amine, (b) an amino acid-type amphoteric surfactant, and (c) an aliphatic dicarboxylic acid, and can therefore impart improved cosmetic effects, such as coating properties, to keratin fibers. Furthermore, remarkably, compositions containing combinations of components (a) to (c) can exhibit good stability over time without causing precipitation problems. [Examples]

[0143] 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.

[0144] [method] Each of the compositions from Examples 1-4 (Ex.1-Ex.4) and Comparative Examples 1-4 (Comp.Ex.1-Comp.Ex.4) 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.

[0145] Phase separation occurred immediately after preparation in the composition of Comparative Example 4. Therefore, the following evaluations were not performed on the composition of Comparative Example 4.

[0146] Bleached hair (Chinese, 2.7g, 27cm) was washed with plain shampoo and then rinsed. Subsequently, for sensory evaluation, 0.4g / 1g of each composition from Examples 1-4 and Comparative Examples 1-3 was applied to the bleached hair.

[0147] [evaluation] (stability) Each composition was left to stand at 50°C for two weeks. After two weeks, the stability of the compositions was investigated by observing the bulk texture. Stability was scored according to the following criteria. OK: The bulk was as smooth as it was immediately after preparation. NG: Yellowing of the bulk material was observed.

[0148] (Sensory evaluation) A sensory evaluation was conducted regarding the coating properties, specifically the amount of coating applied and its smoothness. These attributes were evaluated by three experimental experts based on the following criteria. Coating amount 1: A generous amount 2: Enough 3: Somewhat insufficient 4: Insufficient Smoothness 1: Very smooth 2: Smooth 3: Slightly not smooth 4: Not smooth

[0149] The scores were averaged and shown in Table 1. A lower overall score indicates a perceived higher quality coating.

[0150] The results are shown in Table 1.

[0151] [Table 1]

[0152] As shown in Table 1, the method according to the present invention, which includes the step of applying a composition containing a combination of components (a) to (c), was able to impart improved coating properties to the hair in terms of coating amount and smooth feel when the composition was applied to the hair. In addition, the composition remained stable even after two weeks at 50°C. Accordingly, it can be said that the composition according to the present invention is stable and can impart improved coating properties to the hair when applied.

[0153] On the other hand, the methods of Comparative Examples 1 and 2, each containing a carboxylic acid that is not an aliphatic dicarboxylic acid, and the method of Comparative Example 3, which contains an acid that is not a dicarboxylic acid, failed to provide sufficient coating properties to the hair. In addition, the compositions of Comparative Examples 1-3 showed bulk yellowing after 2 weeks at 50°C, indicating a lack of stability. Phase separation observed immediately after preparation in the composition of Comparative Example 4, which contains an acid that is not a dicarboxylic acid, also indicates a lack of stability in this composition.

[0154] Therefore, it can be concluded that the method according to the present invention is very preferable for conditioning keratin fibers, especially hair.
