Description

The present invention relates to a powdered cosmetic that is applied to at least a portion that comes into contact with the mask when the mask is worn.

To finish the makeup, it is common to use face powder with a small amount of oil. Since face powder absorbs sebum and sweat, it has the aesthetic effect of making the foundation last longer and preventing makeup from coming off, and the powder diffuses light to make the skin look three-dimensional. In addition, the wrinkles of eye shadow and uneven cheeks may be resolved by carefully applying face powder.

Patent Document 1 describes a finishing cosmetic containing a fine cellulose fiber and a polymer having a film-forming ability as a finishing cosmetic capable of preventing makeup breakage and secondary adhesion of the cosmetic. Immediately after spraying with a spray or mist, this cosmetic forms a soft film to cover makeup such as foundation, and can suppress makeup breakage and secondary adhesion.

There are more opportunities to use masks for the purpose of preventing infections such as bacteria and viruses, blocking pollen, house dust, etc. that cause bronchitis, asthma, allergic diseases, etc., and also from the viewpoint of controlling the cold. ing. When using a mask with make-up, there is a problem that the make-up adheres to the mask and the make-up is easily broken. In addition, there is a problem that skin irritation occurs due to rubbing between the mask and the skin. In particular, in recent years, there have been increasing opportunities to use masks regardless of the season from the viewpoint of infection prevention, and there is a high demand for preventing makeup breakage and skin irritation caused by wearing masks.

As a result of diligent studies by the present inventors, makeup breakage and skin irritation caused by wearing a mask are not only caused by secondary adhesion to the mask and rubbing between the mask and the skin, but also in the gaps and boundaries between the mask and the skin. It was found that the stuffiness of the skin makes it easier to remove makeup, and the stuffiness inside the mask promotes skin irritation, which also contributes to the high humidity inside the mask.
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a powdered cosmetic that can suppress makeup breakage and skin irritation caused by wearing a mask.

Powdered cosmetics were prepared by a conventional method according to the formulations listed in Tables 1 and 2 below, and the amount of water absorption was measured by the following method. In addition, the dispersibility was evaluated according to the following criteria.

(Amount of water absorption)
The prepared powdered cosmetic was allowed to stand at 70 ° C. for 12 hours. After that, 1 g of powdered cosmetics is precisely weighed in an atmosphere of 25 ° C, collected on a glass plate, ion-exchanged water is poured little by little into the center of the powder, and kneaded evenly with a spatula each time, and the whole is pasted. It was calculated by the following formula, with the end point immediately before fluidization.
Water absorption (g / 100g) = (ion-exchanged water (g) / sample amount (g)) x 100

(Dispersity evaluation)
Put 3 g of the prepared powder cosmetic in a glass test tube and let it drop naturally 100 times from a height of 5 cm. After that, hold the test tube with the mouth down, drop it naturally once from a height of 2 cm, repeat the drop, count the number of drops required until all the powder in the glass tube comes out, and evaluate according to the following criteria bottom.
A: 0 to 6 times B: 7 to 13 times C: 14 to 20 times D: 21 times or more

The evaluation results are shown in Tables 1 and 2 together with the prescription.
The details of the product names of the raw materials in the table are as follows.

As shown in Table 1, Example 1 used a powder having a different shape from the porous spherical powder, but had a high water absorption. On the other hand, in Comparative Example 1, the porous spherical powder was changed to the non-porous spherical powder in Example 1, but in this case, the water absorption was low. Since the makeup breakage is caused by the amount of water absorbed in the mask, it can be inferred that the makeup breakage of Example 1 suppresses the makeup breakage.

Further, as shown in Table 2, Example 2 uses a porous spherical powder and a powder having a different particle size, and Examples 1 and 3 use a powder having a different shape from the porous spherical powder. , All had good dispersibility. On the other hand, Comparative Example 2 used only the porous spherical powder, and Comparative Example 3 used the powder having the same particle size as the porous spherical powder, but these had poor dispersibility.
