EXAMPLES Next, the present invention will be described more specifically with reference to examples, but the present invention is not limited to these examples.
In addition, the compounding amount is weight%.

Pack cosmetics were prepared according to the formulation shown in Table 1 by a conventional method, and the usability was evaluated by conducting a practical use test. In addition, the effects of exfoliation were evaluated by performing a practical use test.

[Preparation Method] The powder phase of B was added to the aqueous phase of A and mixed with stirring, then the alcohol phase of C was added and further mixed with stirring to obtain a packed cosmetic.

[Evaluation of Usability] A group of 10 women actually used the manufactured pack cosmetics, and conducted a sensory test on the freshness, slipperiness and peeling, and evaluated according to the following criteria. . ◎: Eight or more of the ten responded that they were good. ：: 6 or more respondents answered that they were good. B: 4 or more out of 10 responded that they were good. ×: Less than 4 out of 10 responded as good.

"Exfoliating effect" by applying a pack cosmetic,
After the massage is performed for 5 minutes, the packed cosmetic that has been left standing for 3 minutes and applied is collected from the skin surface. A few drops of a 1: 1 mixture of a saturated aqueous solution of rhodamine B and methylene blue are dropped onto the collected cosmetic pack, and the number of exfoliated cells in the sample is compared by microscopy. Was determined. ：: The number of keratins clearly removed from the control (Comparative Example 3) is larger. Δ: The number of keratins slightly removed than the control (Comparative Example 3) is ×. Control: (Comparative Example 3). )

As shown in Table 1, the pack cosmetics of the present invention of Examples 1 and 2 in which a betaine derivative and a higher fatty acid were blended were compared with Comparative Examples 1 to 3 in which the betaine derivative and the higher fatty acid were not blended. Compared to the pack cosmetics of the above, it has extremely excellent usability in terms of freshness, slippery feeling and peeling off, and also has an excellent exfoliating effect.
