Description

Technical Field

[0001] The present invention relates to cosmetics.

Background Art

[0002] Conventionally, in a sheet-shaped cosmetic formed by housing a sheet-shaped base material impregnated with a liquid agent in a container, there has been a problem that the container discolors due to rust generated by the contact between the liquid agent and a metal (for example, aluminum) contained in the container, and improvement has been demanded. In recent years, that problem has been gradually solved by coating the container with a polyethylene layer to impart a rust prevention effect. However, in recent sheet-shaped cosmetics, there has been a concern that discoloration still occurs because no rust prevention measures (such as coating with a polyethylene layer) are taken for the exposed portion when the flap label portion provided on the container is peeled off.

[0003] Also, as the liquid agent in conventional sheet-shaped cosmetics, for example, a liquid cosmetic composition containing a menthol-based cooling agent, polyoxyethylene hydrogenated castor oil, edetic acid, silica, etc. has been proposed (see, for example, Patent Document 1). However, in conventional cosmetics including Patent Document 1, no consideration has been given to imparting a rust prevention effect to the container against the liquid agent. In addition, there has been a concern that the discoloration of the container is significant due to the promotion of the oxidation reaction in a high-temperature storage environment.

[0004] Therefore, it is desired to provide a cosmetic having an excellent rust prevention effect against aluminum even in a high-temperature storage environment.

Examples thereof include maltose, cellobiose, lactose, etc. Among these, from the viewpoint of achieving a good rust-preventing effect, maltose and lactose are preferable, and maltose is more preferable.

[0013] As the component (A), a synthetic product may be used as appropriate, or a commercially available product may be used.

However, from the viewpoints of good rust prevention effect and no stickiness after use, it is preferably 1% by mass or more and 5% by mass or less, more preferably 1.5% by mass or more and 4.5% by mass or less, based on the total amount of the liquid agent. When the content of the component (A) is 1% by mass or more based on the total amount of the liquid agent, the rust prevention effect is good. When the content of the component (A) is 5% by mass or less based on the total amount of the liquid agent, the absence of stickiness after use is good.

[0015] <One or more selected from (B) aminocarboxylic acid chelating agents, phosphonic acid chelating agents, and phosphate chelating agents> The component (B) imparts a good rust prevention effect to the liquid agent.

For example, methods such as dropping or spraying the liquid agent onto the sheet-like base material, applying the liquid agent to the sheet-like base material, and immersing the sheet-like base material in the liquid agent can be mentioned.

[0052] <<Use>> The use of the cosmetic of the present invention is not particularly limited and can be appropriately selected according to the purpose. However, since it has an excellent rust prevention effect on aluminum even under a high-temperature storage environment, for example, it can be suitably used for face sweat wiping sheets, body sweat wiping sheets, body deodorant sheets, foot wiping sheets, nursing care wiping sheets, sebum wiping sheets, drowsiness-awakening sheets, etc.

The next day (after 24 hours), the "rust prevention effect" was determined based on the following evaluation criteria. The number of samples was 1. - Evaluation criteria for rust prevention effect - ◎: No rust on aluminum ○: Almost no rust on aluminum △: Rust on aluminum ×: Considerable rust on aluminum

[0057] <Evaluation of the absence of stickiness after use> Using the cosmetics of Examples 1 to 20 and Comparative Examples 1 to 6, the "absence of stickiness after use" when nine female professional evaluators in their 20s to 30s wiped back and forth three times along a 10-cm length on the inner side of the upper arm was evaluated according to the following evaluation criteria. - Evaluation criteria for the absence of stickiness after use - ◎: Eight or more people answered "no stickiness". ○: Six or more and seven or fewer people answered "no stickiness". △: Three or more and five or fewer people answered "no stickiness". ×: Two or fewer people answered "no stickiness".
