とができる。The pH of an aqueous solution of an N-acyl neutral amino acid salt is from 7.0 to 10.0 in a 1% aqueous solution, which is neutral to alkaline. It is desirable to make the pH slightly acidic. In addition, studies by the present inventors have confirmed that foaming occurs in the pH range of 5 to 7, and that the foam has good creamy properties. When the pH of the aqueous solvent of these surfactants is adjusted to a weak acidity with an organic acid or the like, an N-acyl neutral amino acid is generated, and the viscosity increases to form a stable liquid crystal structure in an aqueous solution. Optimum product viscosity can be obtained by adding a small amount.

発明の範囲を外れると好ましくない。From the results shown in Table 1, it can be seen that the hair cleansing compositions of the present invention (Examples 1 to 3) are stable compositions having very little change in viscosity in the weakly acidic range of pH 5 to 7. In addition, the hair cleansing compositions (Comparative Examples 1 to 3) which contain the component (c) of the present invention but lack the component (b) contain a viscosity stabilizer, and therefore have a slight effect of stabilizing the viscosity. However, there is a change in viscosity in the range of pH 5 to 7 due to lack of component (c). Further, a hair cleansing composition using an N-acyl acidic amino acid salt instead of the component (a) of the present invention (Comparative Example 4)
6) and hair cleansing compositions using isoprene glycol in place of component (c) of the present invention (Comparative Examples 7 to 9)
In the range of H5 to H7, the change in viscosity was remarkable, and some of them were cloudy in appearance. Furthermore, the hair cleansing composition of the present invention containing too much component (c) (Comparative Examples 10 to 12) becomes cloudy in appearance, and the hair cleansing composition containing too little component (c) (Comparative Example 13). (15) to (15) are insufficient in the effect of stabilizing the viscosity in the pH range of 5 to 7, and are not preferred if the mixing ratio of the component (c) is out of the range of the present invention.

る。From the results shown in Table 2, the hair cleansing compositions of the present invention (Examples 4 to 7) have viscosity stability in the pH range of 5 to 7;
It can be seen that it is excellent in all aspects of appearance, foaming, and creaking during rinsing. The hair cleansing composition lacking the component (c) of the present invention (Comparative Examples 16 to 19) has a pH of 5 to 5.
The hair cleaning composition (Comparative Example 20) in which the viscosity change in the 7 regions is remarkable and the component (a) is smaller than the component (b) is:
The hair cleaning composition (Comparative Example 21) in which the foaming becomes insufficient and the total concentration of the components (a), (b) and (c) is more than 30% by weight is inferior to rinsing, and the hair is less than 10% by weight. The cleaning composition (Comparative Example 22) had insufficient foaming,
Hair cleaning composition with too much component (c) (Comparative Example 23)
Is inferior in appearance, lathering and rinsing properties, and has a component (b)
The hair cleansing composition lacking water (Comparative Example 24) has a change in viscosity (Comparative Examples 1 to 3 in Table 1), is inferior in foaming, has squeakiness upon rinsing, and has N- instead of component (a). Hair cleansing composition using acyl acid amino acid salt (Comparative Example 25)
Shows that the change in viscosity is remarkable (Comparative Examples 4 to 6 in Table 1), the appearance is cloudy, and the foaming is inferior. Example 4-
FIG. 1 shows the change in viscosity with respect to the pH change of the hair cleansing compositions of Comparative Example 7 and Comparative Examples 16 to 20. From FIG. 1, it can be seen that the hair cleansing compositions of Examples 4 to 7 of the present invention have a very small change in viscosity under a weak acid range, and are extremely preferable in terms of product management. On the other hand, in the hair cleaning compositions of Comparative Examples 16 to 20, the viscosity under the weak acid range was significantly changed, and it was found that product management was extremely difficult.

From the results of Tables 3 and 4, even when compounding agents necessary for commercialization, such as storage stabilizers, fragrances, and pigments, are compounded, they have excellent performance in viscosity stability, foaming, and lack of squeaking during rinsing. You can see that.
