Description

[Technical Field]

[0001] The present invention relates to a composition for stabilizing adhesion of lipstick. [Background technology]

[0002] Lipstick is generally manufactured by dispersing coloring agents in oils, etc. The reason for dispersing coloring agents in oils, etc. is to improve adhesion and spreadability on the lips.

[0003] As mentioned above, lipstick is manufactured by dispersing coloring agents in oils and other materials, so when the lips come into contact with other objects after lipstick is applied, secondary adhesion occurs, causing problems such as color fading and color transfer.

[0004] For example, if you drink tea after applying lipstick to your lips, secondary adhesion may occur on the rim of the teacup or other object that your lips come into contact with, resulting in discoloration, color transfer, etc. Also, in today's lifestyles, if you apply lipstick to your lips and then put on a mask, secondary adhesion may occur on the surface of the mask that comes into contact with your lips, resulting in discoloration, color transfer, etc.

[0005] This is thought to be due to insufficient adhesion stability caused by an excess of oily materials that are blended into lipstick to improve adhesion and spreadability on the lips.

[0006] BACKGROUND ART Various proposals have been made in the past to prevent oily makeup cosmetics such as lipstick and oily foundation from transferring to cups and the like, or from adhering to clothing and the like (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Japanese Patent Application Publication No. 2020-180089 Summary of the Invention [Problem to be solved by the invention]

[0008] An object of the present invention is to provide a composition for stabilizing the adhesion of lipstick, which improves the adhesion stability of lipstick and prevents problems such as lipstick fading and color transfer. [Means for solving the problem]

[0009] The inventors of the present application have found that by absorbing excess oil, which is a factor in reducing adhesion stability after lipstick is applied to the lips, with an adhesion stabilizing composition having high oil absorption properties, adhesion stability can be improved and the occurrence of color fading, color transfer, etc. can be suppressed, and have completed the present invention.

[0010] In the above, rice flour can be used as the adhesive stabilizing composition having high oil absorption properties, and the present invention can be exemplified as follows. [1] A composition for stabilizing the adhesion of lipstick, comprising 30% to 90% by mass of rice flour.

[0011] [2] [1] A composition for stabilizing the adhesion of lipstick, further comprising one or more of wheat flour, corn starch, and potato starch.

[0012] [3] The composition for stabilizing the adhesion of lipstick according to [1] or [2], further comprising one or more of talc, kaolin, sericite, and anhydrous silicic acid. [Effects of the Invention]

[0013] According to the present invention, it is possible to provide a composition for stabilizing the adhesion of lipstick, which improves the adhesion stability of lipstick and prevents problems such as lipstick fading and color transfer. DETAILED DESCRIPTION OF THE INVENTION

[0014] The composition for stabilizing adhesion of lipstick according to the present invention contains rice flour in an amount of 30% to 90% by mass.

[0015] Rice flour has high oil absorption properties. Therefore, the composition for stabilizing the adhesion of lipstick according to the present invention, which contains 30% to 90% by mass of rice flour, absorbs excess oil that reduces the adhesion stability of lipstick, improving the adhesion stability of lipstick and preventing the aforementioned color fading and color transfer.

[0016] In order to achieve this purpose, it is desirable that rice flour be blended in the composition for stabilizing adhesion of lipstick according to the present invention in a proportion of at least 30% by mass.

[0017] Furthermore, if rice flour is blended in a proportion exceeding 90% by mass with the lipstick adhesion stabilization composition of the present invention, this is undesirable because it may interfere with the objective of improving the adhesion and spreadability of the oily ingredients blended into the lipstick to the lips.

[0018] The lipstick adhesion stabilizing composition of the present invention can be used, for example, by applying it over lipstick already applied to the lips. By applying it over lipstick already applied to the lips, the above-mentioned effects and functions can be exerted and the purpose can be achieved.

[0019] That is, when used as described above, the rice flour contained in the composition for stabilizing lipstick adhesion according to the present invention at a ratio of 30% to 90% by mass absorbs excess oil in the lipstick, preventing secondary adhesion, strengthening the adhesion of the lipstick to the lips and suppressing color transfer and fading. Furthermore, because rice flour becomes transparent when it absorbs the oil, it does not significantly affect the original color of the lipstick.

[0020] Furthermore, rice flour, which is made from rice, a natural substance that is eaten, is safe for lips on which lipstick is applied, and is harmless even if ingested by humans.

[0021] The composition for stabilizing adhesion of lipstick according to the present invention can further contain one or more of wheat flour, corn starch, and potato starch.

[0022] These plant-derived components can be used as agents for adjusting the transferability, dispersibility, and adhesion of the lipstick adhesion stabilizing composition according to the present invention.

[0023] The lipstick adhesion stabilizing composition according to the present invention can further contain one or more of talc, kaolin, sericite, and silicic anhydride.

[0024] These mineral components can also be used as agents for adjusting the transferability, dispersibility and adhesion of the lipstick adhesion stabilizing composition according to the present invention.

[0025] The composition for stabilizing adhesion of lipstick according to the present invention can be produced by mixing the above-mentioned components in powder form.

[0026] <Example 1 of composition for stabilizing adhesion of lipstick> A composition for stabilizing adhesion of lipstick was prepared according to the following blending ratio (unit: mass %). Rice flour: 80% Wheat flour: 8% Cornstarch: 6% Kaolin: 6% Total: 100% The above-mentioned components were each powdered and then mixed together to prepare a composition for stabilizing adhesion of lipstick according to Example 1.

[0027] <Example 2 of composition for stabilizing adhesion of lipstick> A composition for stabilizing adhesion of lipstick was prepared according to the following blending ratio (unit: mass %). Rice flour: 70% Potato starch: 5% Sericite: 10% Silica: 15% Total: 100% The above-mentioned components were each powdered and then mixed together to prepare a composition for stabilizing adhesion of lipstick according to Example 2.

[0028] <Comparative Study Test 1> Three types of commercially available lipstick were applied to the lips of each subject, and 10 minutes after application, tissue was pressed against each lip and the transfer of color to the tissue was visually observed.

[0029] Next, in the same manner as above, three types of commercially available lipstick were applied to the lips of the subjects, and then the composition for stabilizing lipstick adhesion of Example 1 was applied over the lipstick that had been applied to the lips.

[0030] After 10 minutes had passed since the composition for stabilizing lipstick adhesion according to Example 1 was applied in layers, a tissue was pressed against each lip, and the transfer of color to the tissue was visually observed.

[0031] When only three types of commercially available lipstick were applied, color transfer onto tissue was observed in all cases.

[0032] On the other hand, when the composition for stabilizing adhesion of lipstick according to Example 1 was applied over the lipstick, no color transfer to the tissue was observed in any case.

[0033] <Comparative Study Test 2> The three commercially available lipsticks used in Comparative Study Test 1 were each applied to the lips of a subject, and 10 minutes after application, a tissue was pressed against each lip and the transfer of color to the tissue was visually observed.

[0034] Next, in the same manner as above, three types of commercially available lipstick were applied to the lips of the subjects, and then the composition for stabilizing lipstick adhesion of Example 2 was applied over the lipstick that had been applied to the lips.

[0035] After 10 minutes had passed since the composition for stabilizing lipstick adhesion according to Example 2 was applied in layers, a tissue was pressed against each lip, and the transfer of color to the tissue was visually observed.

[0036] When only three types of commercially available lipstick were applied, color transfer onto tissue was observed in all cases.

[0037] On the other hand, when the composition for stabilizing adhesion of lipstick according to Example 2 was applied over the lipstick, no color transfer to the tissue was observed in any case.

[0038] From the results of Comparative Tests 1 and 2, it was confirmed that the composition for stabilizing lipstick adhesion having the configuration of the present invention, when applied over lipstick already applied to the lips, can improve the adhesion stability of the lipstick and prevent problems such as lipstick fading and color transfer.

[0039] Although the embodiments and examples of the present invention have been described above, the present invention is not limited to the above-described embodiments and examples, and various modifications can be made within the technical scope grasped from the claims.
