Description

The present invention relates to sheet cosmetics.

When the sheet cosmetic is wiped off the skin, dirt such as sweat, sebum, dust, etc. can be adsorbed onto the sheet side, and the effect of the cosmetic composition can provide a refreshing feeling, a dry feeling, etc. On the other hand, the act of wiping the skin puts stress on the skin, which may cause skin problems in some cases, and there are users whose skin types cannot use sheet cosmetics.

There is a technology that suppresses the sticky feeling caused by sebum and gives the skin a more effective dry feeling (Patent Document 1), and a technology that improves the sustainability of the dry feeling imparted to the skin by using sheet cosmetics (Patent Document 2). Proposed. However, these techniques are based on wiping, and it is difficult to obtain a satisfactory effect of removing sebum stains or imparting a dry feeling by pressing the product against the skin.

<Transferability of ester oil to nonwoven fabric (sebum removal effect)>
Drop 0.2 mL of the colored ester oil used in the evaluation of <ester oil dispersibility> on the inner side of the forearm, and apply each sheet cosmetic 1 obtained in Examples and Comparative Examples so as to cover the dropped colored ester oil. The sheet was pressed several times, and the number of times it was pressed until the colored ester oil on the skin could be sufficiently removed was measured and evaluated using the following criteria. The fewer the number of times of pressing required to sufficiently remove the colored ester oil, the better the transferability of the ester oil to the nonwoven fabric and the better the sebum removal effect on the skin.
A (Excellent): Colored ester oil was sufficiently removed in 2 or less times B (Good): Colored ester oil was sufficiently removed in 3 to 4 times C (Poor): Colored ester was removed even in 5 times Oil could not be removed sufficiently

<Actual use evaluation>
One sheet of each cosmetic sheet obtained in Examples and Comparative Examples was pressed twice on one forearm and one side of the neck, and after the pressed cosmetic composition on the skin had dried, the stickiness after use was confirmed. The following evaluation criteria were used to evaluate the dryness, the staying power of the dry feeling, and the absence of powder floating. The above evaluation was conducted by three expert evaluators under constant temperature and humidity conditions of 25° C. and 50% RH.

(1) No stickiness after use A (excellent): No stickiness felt at all.
B (Good): Stickiness is hardly felt.
C (Poor): Stickiness is clearly felt.

(2) Sustainability of dry feeling A (excellent): The skin feels sufficiently dry after use.
B (good): Although inferior to A, the skin feels dry after use.
C (Poor): The skin does not feel dry after use. Or feel dry.

(3) No powder floating A (excellent): No powder floating on the skin after use.
B (Good): Slight powder floating on the skin after use, but usable.
C (Poor): Powder floating was noticeable on the skin after use.

From the results in Table 1, it is clear that the sheet cosmetic of the present invention, in which a prescribed nonwoven fabric is impregnated with a cosmetic composition containing a prescribed surfactant, cellulose powder, alcohol, and water, can be easily applied to the skin by simply pressing it against the skin. It can be seen that the sebum stains on the skin can be sufficiently removed, and that the effect of imparting a dry feeling and suppressing powder floating are also good.
