The method of using the cosmetics of the present disclosure will be described. FIG. 4 shows a flowchart showing how to use the cosmetics of the present disclosure. FIG. 5 shows a schematic cross-sectional view of the cosmetics of the present disclosure in the first step.

First, shear stress is applied to the cosmetic 2 inside the soft container 3 from the outside of the container body 11 (first step; S1). For example, shear stress can be applied to the cosmetic 2 by rubbing the container body 11 by hand so that the cosmetic 2 in the container body 11 is deformed. As a result, the viscosity or hardness of the cosmetic 2 can be reduced by the thixotropy of the cosmetic 2.

Next, at least a part of the cosmetic whose viscosity or hardness has decreased due to shear stress is taken out of the container body 11 by the cosmetic tool 20 (second step; S2). The user can make up directly with the taken out cosmetics. As a result, the makeup can be made with a low-viscosity cosmetic, which facilitates the makeup. On the other hand, the cosmetics of the present disclosure contain a large amount of a solidifying agent, and make-up transfer and make-up disintegration are suppressed.

The first step is preferably performed with the cosmetic tool 20 attached to the soft container 3. When the coating portion 23 is inside the container body 11, it is preferable to knead the container body 11 so that shear stress is applied to the cosmetic 2 in the vicinity of the coating portion 23, as shown in FIG. As a result, the viscosity or hardness of the cosmetic 2 around the coating portion 23 can be reduced. When the grip portion 21 functions as a lid, it is possible to prevent the cosmetic 2 from leaking when the soft container 3 is being kneaded.

When a shear stress is applied to the cosmetic 2 in a state where the coating portion 23 is not inside the container body 11, the coating portion 23 is put into the container body 11 after reducing the viscosity or hardness of the cosmetic 2. , Cosmetics 2 can be taken out.

The cosmetics of the present invention include lipsticks, lip glosses, lip bases for bases, lipstick overcoats, lip cosmetics such as lip balms, makeup cosmetics such as eye shadows, cheeks, foundations and eyeliners, skin care cosmetics, and hair cosmetics. It can be applied to charges.

According to the cosmetics of the present disclosure and the method of use thereof, the viscosity of the cosmetics is low at the time of use, so that makeup is easy. On the other hand, after make-up, even though the viscosity is low at the time of make-up, make-up transfer (make-up removal) and make-up disintegration are suppressed.

The cosmetics of the present disclosure are provided with cosmetics and are excellent in portability.

The application part of the cosmetic tool can be stored in the cosmetic. As a result, it is not necessary to wash the cosmetics each time they are used, so that the cosmetics of the present disclosure are excellent in convenience. In addition, since it is only necessary to apply force to the portion where the coating portion is located, it is also excellent in ease of use.

The present invention will be described in more detail with reference to Examples below, but the present invention is not limited thereto. Unless otherwise specified, the blending amount is shown in% by weight with respect to the system in which the component is blended.
Prior to the description of the examples, the evaluation test method used in the present invention will be described.

Evaluation (1): Hardness measurement test "Hardness" (third hardness) after filling and solidifying the sample immediately after preparation (without applying shear stress) and 30 by hand after filling and solidifying the sample in a container. The "hardness after compression" (first hardness) after being rubbed and taken out of the container was measured by the following method.
The hardness after compression is the average value of 5 times.
(Hardness measurement method)
Using a rheometer manufactured by Sun Scientific Co., Ltd., the load weight is 2 kg, the needle diameter is 11.3φ, the needle insertion depth is 3 mm, the ascending speed is 20 mm / min, and the measurement temperature is 25 ° C.

Evaluation (2): Ease of compression The ease of compression when 10 specialized panels kneaded by hand 30 times was evaluated.
S: 8 or more out of 10 responded that they were good.
A: More than 6 out of 10 responded that they were good.
B: 4 or more out of 10 responded that they were good.
C: Less than 4 out of 10 responded that it was good.

Evaluation (3): Stability A sample was prepared and evaluated for stability after storage at 40 ° C. for 30 days.
A: There was no problem and it was good.
B: The product was rejected due to changes in properties such as separation.

Evaluation (4): Usability (makeup stickiness, film thickness feeling at the time of application)
Ten specialized panels applied the sample to the lips and evaluated the feeling of use (makeup stickiness, film thickness feeling at the time of application) at the time of application. The sample was applied to the lips after being rubbed by hand 30 times.
S: 8 or more out of 10 responded that they were good.
A: More than 6 out of 10 responded that they were good.
B: 4 or more out of 10 responded that they were good.
C: Less than 4 out of 10 responded that it was good.

The present inventors produced the cosmetics (cosmetics for lips) shown in Tables 1 and 2 below by a conventional method, filled them in a soft container (pouch-shaped container), and measured them by the above evaluation method. The results are shown in Tables 1 and 2.

From the evaluation results of Test Example 1-1, it can be seen that the hardness of the cosmetic containing only a large amount of wax is too high at the time of use. Therefore, even if the container was rubbed by hand, it was too hard to be taken out of the container and applied.
On the other hand, in Test Example 1-2 in which the dextrin fatty acid ester was added to Test Example 1-1, the hardness was lowered by rubbing by hand at the time of use, and it was easy to apply.
In addition, Test Example 1-5 in which the amount of dextrin fatty acid ester was increased in Test Example 1-2 became liquid and was inferior in cosmetic durability and film thickness.
Test Example 1-6, which did not contain the dextrin fatty acid ester, had no problem in hardness, but even if the container was rubbed by hand, it was too hard to be applied out of the container well.

Test Examples 1-3 and 1-4, which did not contain wax and contained a large amount of dextrin fatty acid ester, did not have a low hardness after compression.

From these facts, the cosmetic product of the present invention contains (a) wax 5 to 50% by mass, (b) dextrin fatty acid ester 0.1 to 5% by mass, and (c) polar oil content 40 to 90% by mass. The cosmetic having a hardness of 70 to 3500 gf measured in 1 is a cosmetic filled in a soft container.

Next, the present inventors examined the stability and usability of cosmetics such as those of the present invention. The present inventors produced the cosmetics (cosmetics for lips) shown in Table 3 below by a conventional method, filled them in a soft container (pouch-shaped container), and evaluated them by the above evaluation method. The results are shown in Table 3.

Test Example 2-1 containing no wax and containing a large amount of dextrin fatty acid ester has a low hardness of 50, can be easily taken out from a tube without sharing, and has stability as well as Test Example 1. It was equivalent to -2, but had poor makeup retention.
Test Example 2-2, which did not contain the dextrin fatty acid ester, became liquid and was inferior in cosmetic durability and film thickness at the time of application.

Next, the types of wax were examined.
The present inventors produced the cosmetics (cosmetics for lips) shown in Table 4 below by a conventional method, filled them in a soft container (pouch-shaped container), and measured them by the above evaluation method. The results are shown in Table 4.

From the evaluation results in Table 4, it was clarified that the cosmetic of the present invention can be prepared with various kinds of waxes.

Next, the blending amount of wax was examined.
The present inventors produced the cosmetics (cosmetics for lips) shown in Table 5 below by a conventional method, filled them in a soft container (pouch-shaped container), and measured them by the above evaluation method. The results are shown in Table 5.

From the evaluation results in Table 5, in Test Example 4-1, the hardness was too high because the amount of wax was too large, and it was possible to obtain a cosmetic suitable for filling in a tube container and using even if the share was applied. I found that I couldn't. Further, in Test Example 4-4, the amount of wax was too small, so that it became liquid, and the feeling of film thickness at the time of application was inferior.

Therefore, the cosmetic product according to the present invention is characterized in that the blending amount of wax is 5 to 50% by mass and the third hardness is 70 to 3500 gf.

For the cosmetics of Test Example 1-2, after measuring the hardness after compression (first hardness), the second hardness was measured by allowing the container to stand for 4 weeks in a closed state to recover the hardness. The method for measuring hardness is the same as above. The results are shown in Table 6.

It was confirmed that the hardness decreased by compression (shear stress) became higher than the first hardness by standing still. The recovered second hardness was lower than the third hardness immediately after preparation, and was a hardness that was easy to knead. Further, when the cosmetic having recovered hardness was subjected to shear stress again, the hardness could be lowered to the first hardness suitable for use.

Cosmetics having the forms shown in FIGS. 1 to 3 containing the cosmetics of Test Example 1-2 as lip cosmetics in the tube-shaped soft container of the present disclosure, and the cosmetics in a general tube container. We compared the usability with the cosmetics put in. The general tube used is a tube that is often used for toothpaste and the like, and the cosmetic tool is a separate tool from the tube.

In the cosmetics of the present disclosure, with the cosmetics attached to the tubular soft container, the chips were taken out from the container body after kneading only the positions corresponding to the chips (applied portion) several times. The cosmetics attached to the chips had a low viscosity and were in a state of being easy to apply.

On the other hand, in a general tube, in order to facilitate the removal of cosmetics from the opening, it is necessary to knead the tube as a whole, and the number of times of kneading and the number of kneaded parts are larger than those of the cosmetics of the present disclosure. Further, since the opening portion of a general tube was covered with a cap and had a hardness that could not be deformed by hand, the opening portion could not be kneaded. That is, shear stress could not be applied to the cosmetics existing in the opening. For this reason, the cosmetics present in the opening portion first extruded from the general tube have a high viscosity and are difficult to apply. In addition, the cosmetics adhering to the chips used for application harden or solidify if left unattended, and therefore need to be washed. From this, it was found that the cosmetics of the present disclosure can enhance the ease and convenience of makeup.
