First, the inventors of the present invention conducted a sensory evaluation based on the above criteria for a pack cosmetic containing the above basic composition and containing 10% by mass of each alkylene oxide derivative and each humectant. The results are shown in Table 1.

[0058]

[Table 1] As a result, in pack cosmetics containing polyvinyl alcohol, compared with general moisturizers such as glycerin or 1,3-butylene glycol, by adding EO / PO derivatives having hydrocarbon groups bonded to both ends, It was revealed that excellent quick-drying property, usability and moisturizing effect were obtained. Therefore, the present inventors have proceeded with the study on the suitability of the polyvinyl alcohol and the alkylene oxide derivative as a pack cosmetic.

[0061]

[Table 3] As is clear from Table 3, in any of the pack cosmetics using various polyvinyl alcohols having different degrees of polymerization, by blending the alkylene oxide derivative,
Excellent quick-drying property, usability and moisturizing effect were obtained. From the above, in the pack cosmetic according to the present invention, the effect of blending the alkylene oxide derivative is not limited by the degree of polymerization of polyvinyl alcohol,
It is considered that the effect is exhibited when any of the polyvinyl alcohols is blended.

[0063]

[Table 4] As is clear from Table 4, when both R ¹ and R ² have 1 to 4 carbon atoms (compounds 2, 3 and 4), excellent quick-drying property, feeling in use and moisturizing effect are obtained. Was given. On the other hand, when R ¹ and R ² are hydrogen (compound 1),
When the stickiness was strong and R ¹ was C12 (Compound 6), both the feeling in use and the moisturizing property were unfavorable. On the other hand, the sum of carbon numbers of R ¹ and R ² is 7,
Even when the amount was less than that of Compound 4, the moisturizing feeling tended to be deteriorated when R ¹ was C6 (Compound 5). From the above, the alkylene oxide derivative according to the present invention includes R
Both ¹ and R ² need to be hydrocarbon groups having 1 to 4 carbon atoms.

In the actual manufacturing, R ¹ , R ²
Since not all of the above are substituted with hydrocarbon groups, the permissible abundance ratio of the unsubstituted (H) compound was examined. The results are shown in Table 5. In addition, the unsubstituted ratio is the number of hydrogen atoms (Y) to the number of hydrocarbon groups (X).
Is represented by the ratio Y / X. In addition, in Table 5 below, 1: 2 = 9
5: 5 means that the compound 1 and the compound 2 were mixed at a ratio of 95: 5 to prepare a predetermined Y / X.

When it becomes, a sticky feeling is apparently generated. Further, as a result of detailed study by the present inventors, it became clear that Y / X needs to be 0.15 or less.

[Oxyalkylene Group, Oxyethylene Group] Next, the present inventors examined the presence of the oxyalkylene group and oxyethylene group in the alkylene oxide derivative and their suitability as a pack cosmetic. The results are shown in Table 6 below.

[0067]

[Table 6]

[0068]

[Chemical 5]

In Table 6, it is clear from Compound 11 and Compound 12 shown in Chemical Formula 5 that the effect is low, so that in the present invention, from the viewpoint of moisturizing property and usability, oxyalkylene group and oxyethylene group are selected. The existence of both is essential. Further, from the results of Compound 12, it is considered that the effect of the present invention is not merely the effect of adjusting hydrophilicity and hydrophobicity. Further detailed studies by the present inventors have revealed that a suitable ratio of oxyethylene groups to the total of oxyalkylene groups and oxyethylene groups is 20 to 80% by mass.

Further, the present inventors produced a block polymer and a random polymer with the same number of alkylene groups and oxyethylene groups, and compared them.

[0071]

[Table 7] As is clear from Table 7, the effect of the present invention can be obtained with either a block polymer or a random polymer, but an excellent feeling of use can be obtained particularly in the case of a random polymer.
