[Examples]

[0135] 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.

[0136] [method] Each of the compositions from Examples 1 and 2 (Ex.1 and Ex.2) and Comparative Examples 1 to 3 (Comp.Ex.1 to Comp.Ex.3) 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.

[0137] In the composition of Comparative Example 3, precipitation occurred after preparation. Therefore, the following evaluation was not performed on the composition of Comparative Example 3.

[0138] Bleached hair (Chinese, 2.7g, 27cm) was washed with plain shampoo and then rinsed. Subsequently, 0.4g / 1g of each composition from Examples 1 and 2 and Comparative Examples 1 and 2 was applied to the bleached hair.

[0139] After letting the hair stand for 5 minutes, the composition was rinsed with water, and then the hair was dried with a hairdryer.

[0140] [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. Good: The bulk was as smooth as it was immediately after preparation. Normal: The texture was uneven. Poor quality: Granules were observed.

[0141] (Sensory evaluation) A sensory evaluation was conducted regarding the quality of the coating, specifically the amount and softness of the coating on the treated hair. These appearances were evaluated by three experimental experts based on the following criteria. Coating amount 1: A generous amount 2: Enough 3: Insufficient Hair softness 1: Very soft 2: Soft 3: Not soft

[0142] The scores were averaged and shown in Table 1. A lower overall score indicates a perceived higher quality coating.

[0143] The results are shown in Table 1.

[0144] [Table 1]

[0145] As shown in Table 1, the method according to the present invention, which includes the step of applying the compositions of Examples 1 and 2 containing combinations of components (a) to (c), provided the hair with improved sensory effects in terms of increased coating amount and improved softness. In addition, the compositions of Examples 1 and 2 showed good stability over time without causing precipitation problems.

[0146] On the other hand, the methods of Comparative Examples 1 and 2, in which the composition did not contain (c) cross-linked phosphate polysaccharide, failed to produce a sufficient sensory effect on the hair. In addition, the compositions of Comparative Examples 1 and 2 were not very stable. Furthermore, the composition of Comparative Example 3, which similarly did not contain (c) cross-linked phosphate polysaccharide, produced precipitate during compounding, indicating the incompatibility of the components used.

[0147] Accordingly, it can be concluded that the method according to the present invention can provide the benefits of improved conditioning to dry hair and is therefore highly preferable for conditioning hair.
