[0006] Patent Document 2: Japanese Patent Application Publication No. 2019-172576 Summary of the invention

[0007] Problems to be solved by the invention

[0008] In a hair cleansing composition, it is desired that the foaming property and the elasticity of the foam are good from the viewpoint of improving the feeling during use, and it is also desired that the rough feeling of the hair during washing with water is suppressed.

[0009] Conventional hair cleansing compositions containing laureth sulfate can improve foaming properties, but on the other hand, hair tends to feel rough during rinsing with water.

[0010] On the other hand, N-acylamino acid surfactants are ingredients that reduce the roughness of hair when washed with water and have low irritation to hair and skin, and therefore have been compounded into hair cleansing compositions in recent years. However, conventional hair cleansing compositions containing N-acylamino acid surfactants have insufficient foaming properties or insufficient foam elasticity. In addition, in recent years, there has been a further demand for an effect of reducing the roughness of hair when washed with water, and particularly for hair cleansing compositions for damaged hair, an excellent effect of reducing the roughness has been demanded.

[0011] Therefore, an object of the present invention is to provide a hair cleansing composition which can improve foaming properties and foam elasticity and can suppress the rough feeling of hair when washing with water.

[0195] A wig (long hair, manufactured by Beaulax) was bleached using a commercially available bleaching agent. The wig that had been bleached was washed with a shampoo containing cocamidopropyl betaine as the main cleaning ingredient, and then a conditioner containing stearyl trimethyl ammonium chloride as the main care ingredient was applied and rinsed. Then, it was dried with a hair dryer to prepare an evaluation wig. After the prepared evaluation wig was moistened with warm water, 2 g of the obtained hair cleanser composition was evenly applied to the entire hair of the evaluation wig, and the evaluation wig was rubbed to foam. The foaming property was evaluated according to the following criteria.

[0196] <Evaluation Criteria for Foaming Properties>

[0197] ○○ (excellent): Foaming starts from the initial stage of kneading (kneading about 3 times), and foaming is sufficient to cover the entire hair.

[0198] ○ (good): The foam is sufficient to cover the entire hair.

[0199] × (bad): The foam did not cover the entire hair, and the hair was visible.

[0200] (Test Example 2: Elasticity of Bubbles)

[0201] The foam generated in the above-mentioned Test Example 1 was pressed and touched by hand, and the elasticity of the foam was evaluated according to the following criteria.

[0202] <Evaluation Criteria for Bubble Elasticity>

[0216]

[0217] [Table 3]

[0218]

[0219] [Table 4]

[0220]

[0221] (Test Example 4: Preparation Stability)

[0222] 120 mL of the hair cleansing composition obtained in Examples 1, 4, 5, 8-10, and 12 was filled into a mayonnaise bottle and stored at 40°C for 7 days. After storage, the bottle was further left at 25°C for 3 hours. Then, the properties of the hair cleansing composition were visually observed. As a result, no precipitate was generated in the hair cleansing composition obtained in Examples 1, 4, 5, 8-10, and 12, and no significant decrease in viscosity was observed compared to before storage, indicating that the formulation stability was good.

[0223] (Test Example 5: No dripping property)

[0224] About 5 g of the hair cleansing composition obtained in Examples 1, 4-9, 11, and 12 was discharged from a non-foaming dispenser container (pump container) into the palm of one hand, spread on both palms, and then applied to a wig (long hair, manufactured by Beaulax Co., Ltd.). As a result, in the hair cleansing composition obtained in Examples 1, 4-9, 11, and 12, the hair cleansing composition did not drip from the palm in the process from discharging into the palm to applying to the wig.
