It was allowed to stand in a constant temperature constant temperature room at 5 ° C. for 24 hours or more. After that, the container was placed on a horizontal table, and the pump head was vertically pushed down to the end to discharge bubbles. The state of the foam for 4 pushes discharged by the operation was visually evaluated by one expert panelist according to the following three-step criteria.
A: The texture of the foam is uniform B: The texture of the foam is almost uniform C: The texture of the foam is not uniform The evaluation results are shown in the section of "Foam quality at the time of ejection" in Table 1.

(Storage stability at low temperature (-5 ° C))
About 100 mL of the obtained hair cleansing composition of each example was filled in a 110 mL glass bottle, sealed, and allowed to stand in a constant temperature constant temperature room at −5 ° C. for 3 days, and the appearance was visually observed.
A: Transparent B: Cloudy C: Precipitation, separation or precipitation is observed.

(Bubbling when washing hair in the presence of model sebum)
A Japanese female hair bundle with a length of 30 cm, a width of 6 cm, and a weight of 20 g was thoroughly rinsed with warm water at 40 ° C., and then 0.02 g of model sebum (the composition will be described later) was applied onto the hair bundle. 1.0 g of the hair cleaning agent composition was discharged from the foam ejection container and uniformly applied to the hair, and the hair was whipped so as to be lightly rubbed against each other for about 30 seconds. The goodness of foaming (foaming amount) at that time was sensory-evaluated by one expert panelist according to the following five-step criteria.
5: Very good foaming 4: Good foaming 3: Slightly good foaming 2: Slightly bad foaming 1: Poor foaming

<Model sebum composition>
Ingredients Blended palmitic acid 36.8 parts by mass Oleic acid 18.8 parts by mass Squalene 8 parts by mass Myristyl myristate 14 parts by mass Cotton seed oil 7.2 parts by mass Cholesteryl 12 parts by mass Cholesteryl ester 4 parts by mass 100.8 parts by mass Total

(Foam quality when washing hair in the presence of model sebum)
A Japanese female hair bundle with a length of 30 cm, a width of 6 cm, and a weight of 20 g is thoroughly rinsed with warm water at 40 ° C., then 0.02 g of the above model sebum is applied onto the hair bundle, and 1.0 g of a hair detergent is applied. The composition was discharged from the foam discharge container and applied, and the hair was whipped so as to be lightly rubbed against each other for about 30 seconds. The foam quality at that time was sensory-evaluated by one expert panelist according to the following five-step criteria.
5: Fine and very good quality 4: Fine and good quality 3: Somewhat fine and slightly good quality 2: Somewhat coarse and not very good quality 1: Coarse and not good quality

(Smoothness of hair during rinsing)
A Japanese female hair bundle with a length of 30 cm, a width of 6 cm, and a weight of 20 g is thoroughly rinsed with warm water at 40 ° C., and then 1.0 g of a hair detergent composition is discharged from the above foam discharge container and applied. For 30 seconds, the hair was whipped so as to lightly rub against each other. Then, while rinsing with warm water at 40 ° C., the smoothness of the hair during rinsing was sensory-evaluated by one expert panelist according to the following five-step criteria.
5: Very good smoothness 4: Somewhat good smoothness 3: Somewhat good smoothness 2: Not very good smoothness 1: Not good smoothness

Details of the components used in each example in Table 1 are shown below.
* 1 Polyquaternium-10: Poise C-80M (manufactured by Kao Corporation)
* 2 Cationized guar gum: Jaguar Excel (manufactured by Solvay)

* 4 PPG-9 diglyceryl: SY-DP9 (manufactured by Sakamoto Pharmaceutical Co., Ltd.)
* 5 PPG-7: ADEKA CARPOR DL-30 (manufactured by ADEKA)

From Table 1, the hair cleansing composition obtained in each example was preferable in terms of foam quality when discharged from the pump former and storage stability at low temperature (-5 ° C). The hair cleansing composition obtained in each example is more than that of each comparative example in terms of the balance between the amount and quality of foam during washing and the smoothness of hair during rinsing. It was excellent.
