Description

Technical Field

[0001] The present invention relates to a body cleansing composition (hereinafter also referred to as "formulator body cleansing composition" or simply "cleansing composition") that is filled in a container having a foam discharging function (hereinafter referred to as "formulator container") and is discharged as fine foam for use.

Background Art

[0002] The formulator body cleansing composition has advantages such as shortening the foaming time by discharging foam and gently cleansing with foam to reduce the burden on the skin. Therefore, an excellent amount of foam is required for the formulator cleansing composition, and various studies have been conducted so far. As such a cleansing composition, for example, Patent Document 1 discloses a skin cleansing composition containing a fatty acid salt, lauryldimethylaminoacetic acid betaine, and a dihydric alcohol, and Patent Document 2 discloses a skin cleansing composition containing a polyoxyethylene alkyl ether sulfate, an amphoteric surfactant, and a polyoxyethylene hydrogenated castor oil. These skin cleansing compositions are excellent in the amount of foam during washing.

[0003] On the other hand, even when an excellent amount of foam is produced, if it drips from the washing surface, the effect of gently cleansing with foam will be reduced. In particular, in the case of hair, although the dripping of foam is suppressed by entering the gaps between the hairs, on the body, due to the small surface area, it easily drips. In the above two cleansing compositions, the suppression of this foam dripping may be inferior.

[0004] Among them, as a technique for suppressing the dripping of foam, Patent Document 3 discloses a skin cleansing composition combining an alkyl ether carboxylic acid and an acylated amino acid salt. However, in this composition, when actually discharged onto a surface with a large inclination, the effect of suppressing the dripping of foam may be insufficient. In addition, since the body cleansing composition for a former generally contains a small amount of surfactant, it tends to be difficult to maintain the foam quality of the discharged foam as compared with the foam foamed from a liquid detergent, especially in the bathroom in summer. Although the above three compositions are excellent in maintaining the foam quality of the discharged foam at room temperature such as during hand washing, they may be inferior in maintaining the foam quality under warm conditions such as in the bathroom in summer. Therefore, there is a demand for a body cleansing composition for a former that has excellent foam volume, is less likely to cause dripping of foam, and can maintain the foam quality even under warm conditions.

The total amount was adjusted to 100% by mass with water to prepare body cleansing agent compositions for formers of Examples 1 - 7 and Comparative Examples 1 - 6. Note that as each component in Tables 1 and 2, commercially available products provided for cosmetics were used. The content of each component in Tables 1 and 2 is shown in mass%.

[0041] For each of the detergent compositions of Examples 1 to 7 and Comparative Examples 1 to 6, the following evaluations were carried out for the foam volume, foam dripping, and maintenance of the foam quality of the discharged foam as described in (1) to (3) below. The numerical values shown together in each evaluation in Tables 1 and 2 indicate the average values of the evaluation results or scores obtained in each case.

[0042] <Evaluation of Detergent Composition> (1) Foam volume Take 1.0 g of the detergent composition and dilute it with 9.0 g of purified water, and place it in a 100 mL graduated cylinder so as not to foam. Next, attach a diffuser stone (Bubble Mate, Starlet S105-D manufactured by Sudoh Co., Ltd.) to a goldfish pump (Air Pump, Nichido Non-Noise S200 manufactured by Nippon Animal Drugs Co., Ltd.), immerse the diffuser stone in the diluted solution, and foam it for 3 seconds at a flow rate of 1,000 mL / min. The volume obtained by subtracting the initial total volume of the diluted solution and the diffuser stone (18 mL) from the scale of the graduated cylinder at the top of the foam at that time is defined as the foam volume, and the foam volume of the detergent composition was evaluated in four grades of "◎", "○", "△", and "×" according to the following evaluation criteria. When the evaluation is "◎" or "○", it is considered qualified. <Evaluation Criteria> ◎: Foam volume is 70 mL or more ○: Foam volume is 60 mL or more and less than 70 mL △: Foam volume is 50 mL or more and less than 60 mL ×: Foam volume is less than 50 mL

[0043] (2) Foam dripping The cleaning agent composition was discharged in two pushes from a pump-former container (Yamato Can Co., Ltd.'s "M1-50") onto artificial leather (Idea Tex Japan Co., Ltd.'s "PBZ13001"). The artificial leather was set vertically, and the moving distance of the foam after 30 seconds was measured. Based on the measured distance, the dripping resistance of the foam of the cleaning agent composition was evaluated in four grades of "◎", "○", "△", and "×" according to the following evaluation criteria. The cases where the evaluation was "◎" and "○" were regarded as passing. <Evaluation Criteria> ◎: The moving distance is less than 70 mm ○: The moving distance is 70 mm or more and less than 110 mm △: The moving distance is 110 mm or more and less than 150 mm ×: The moving distance is 150 mm or more

[0044] (3) Maintenance of the foam quality of the discharged foam The cleaning agent composition at 40 °C was discharged in one push from the former container onto the artificial leather in a straight line, and the uniformity of the foam quality of the entire discharged foam after 60 seconds was visually confirmed. This operation was carried out for each of the four panelists, and the uniformity of the foam quality was evaluated according to the following absolute evaluation criteria, and the average score of the four panelists was obtained. Based on the average score, the uniformity of the foam quality of the discharged foam was evaluated in four grades of "◎", "○", "△", and "×" according to the following evaluation criteria. The cases where the evaluation was "◎" and "○" were regarded as passing. The former container and the artificial leather used were the same as those used in (2) above. <Absolute Evaluation Criteria> (Score): (Evaluation) 5: It is 90% or more uniform. 4: It is 80% or more and less than 90% uniform. 3: It is 70% or more and less than 80% uniform. 2: It is 60% or more and less than 70% uniform. 1: It is only 60% or less uniform. <Criteria for Four-Grade Evaluation Based on the Average Score> ◎: The average score is 4 or more ○: The average score is 3 or more and less than 4 △: The average score is 2 or more and less than 3 ×: The average point is less than 2

[0045] For the detergent compositions of Examples 1 to 7, the foam volume, foam dripping, and maintenance of the foam quality of the discharged foam were all good. On the other hand, in Comparative Example 1, since component (b) was not contained, the foam volume, foam dripping, and maintenance of the foam quality were insufficient. In Comparative Example 2, since component (c) was not contained, the foam dripping and maintenance of the foam quality were insufficient. In Comparative Example 3, since the content of component (b) exceeded 5% by mass, the foam volume and maintenance of the foam quality were insufficient. In Comparative Example 4, since N-coconut oil fatty acid acyl-N-methyl taurine sodium (component (a)’) was contained instead of component (a), the foam volume, foam dripping, and maintenance of the foam quality were insufficient. In Comparative Example 5, since N-lauroyl-N-methyl-β-alanine sodium (component (a)’) was contained instead of component (a), the foam volume and maintenance of the foam quality were insufficient. In Comparative Example 6, since polyethylene glycol dilaurate (component (c’)) with an average addition molar number of ethylene oxide less than 50 moles was contained instead of component (c), the foam dripping and maintenance of the foam quality were insufficient.
