The blending amounts described in the table are the blending amounts of each component (that is, the blending amounts of the active ingredients in each raw material. So-called pure components), and are expressed in "mass%" unless otherwise specified.

[0054] In the Examples and Comparative Examples, as the polyethyleneimine, the product name "CC-H700" (manufactured by Nippon Shokubai Co., Ltd., Mw 350,000, amine ratio: primary amine: secondary amine: tertiary amine = 25:50:25, resin content 30 wt%, amine value (mmol / g·solid) 18) was used. Also, as the sodium lauroamphoacetate, the product name "Softazoline LHL-SF" (manufactured by Kawaken Fine Chemical Co., Ltd.) was used.

[0055] (Evaluation) The evaluation was conducted as follows.

[0056] (Test Example 1: Precipitation Inhibiting Effect) 100 g of the cosmetic compositions obtained in the examples and comparative examples were filled into mayonnaise bottles (made of glass, transparent, with a capacity of 140 mL and a diameter of 50 mm) and left standing for 7 days under the condition of 25°C. A round mark (line thickness: about 1 mm, diameter: about 10 mm) was drawn in black magic on the side of the mayonnaise bottle, and visual observation was carried out from the side opposite to the round mark. Through the filled cosmetic composition, it was evaluated according to the following evaluation criteria based on whether the above round mark could be visually recognized and the presence or absence of precipitates. <Evaluation Criteria> 5 (Very Good): There is no precipitate, the cosmetic composition is not turbid, and the round mark can be clearly visually recognized. 4 (Good): There is no precipitate, the cosmetic composition is slightly turbid, but the round mark can be clearly visually recognized. 3 (Usable): A slight amount of precipitate can be seen. Or, there is no precipitate, the cosmetic composition is turbid, but the round mark is visually recognizable. 2 (Bad): The round mark cannot be visually recognized. 1 (Very Bad): Obvious sedimentation has occurred. If the above evaluation is 3, it was determined that the precipitation suppression effect is at an acceptable level.

[0057] (Test Example 2: Odor Suppression Effect) The cosmetic compositions obtained in the examples and comparative examples and the cosmetic composition of the reference example for showing the odor suppression effect by Component A and Component C were used for evaluation. 1 g of the following pseudo-sebum components and 1 mL of pseudo-scalp odor components were mixed to prepare a mixture. 0.2 g of the above mixture was applied to a hair bundle (length: about 15 cm, weight: about 1.0 g) to prepare a hair bundle for evaluation. <Pseudo-Sebum Components> Cholesterol 5% by mass Myristic acid 5% by mass Palmitic acid 10% by mass Stearic acid 2% by mass Oleic acid 10% by mass Triolein 20% by mass Hexadecyl palmitate 30% by mass Squalene 7% by mass Liquid paraffin 11% by mass Total 100% by mass <Pseudo-scalp odor components> Diacetyl 0.2% by volume Acetic acid 1.0% by volume Propionic acid 2.0% by volume Hexanoic acid 2.0% by volume Heptanoic acid 2.0% by volume Octanoic acid 3.0% by volume Nonanoic acid 5.0% by volume Decanoic acid 25.0% by volume Propylene glycol the balance Total 100% by volume

[0058] The cosmetic compositions (shampoos) of the examples, comparative examples, and reference examples were diluted with water to 2% by mass to prepare an aqueous shampoo solution. The above-described hair tufts for evaluation were immersed in the above aqueous shampoo solution and stirred for 10 seconds for washing. Thereafter, they were rinsed with running water for 5 seconds and dried. The odor of the hair tufts after the above washing and drying was smelled, and the odor suppression effect was evaluated according to the following evaluation criteria. The evaluation was performed by three professional evaluators. <Evaluation criteria> 3 (Good): There is no odor, or almost no odor. 2 (Usable): Although an odor is felt, it is clearly weaker compared to the unwashed hair tufts for evaluation. 1 (Bad): Compared to the unwashed hair tufts for evaluation, there is no change in odor, or almost no change.

[0059] The results are shown in the following table.

Table 2

[0062] As shown in the table, the cosmetic composition of the present invention had a sufficient precipitation suppression effect.

[0063] Also, the foaming property of the cosmetic composition (hair shampoo) of the example was evaluated as follows. A hair bundle subjected to bleaching treatment (length: about 20 cm, weight: about 2.5 g) was washed using a shampoo having cocamidopropyl betaine as the main cleaning component, and then dried with a dryer to prepare a hair bundle for evaluation. About 1.2 g of the cosmetic composition of the example was wetted with warm water at about 40°C and then applied to the hair bundle for evaluation that had been drained of moisture. The hair bundle was rubbed 10 times to foam it up. As a result, in Examples 1, 2, 4, 7 to 15, the amount of foam was large and the foaming property was very good. In Examples 3 and 5, although the amount of foam was slightly less, the foaming property was good. In Example 6, the amount of foam was small and the foaming property was slightly inferior.
