Description

Technical Field

[0001] The present invention relates to an oil-based eye cosmetic that exhibits sufficient water resistance, oil resistance, and makeup retention without blending a silicone compound as an oil thickener, and can be easily removed with a commercially available ordinary full-face cleansing oil.

Background Art

[0002] Conventionally, mascara, eyebrow makeup, etc. are known as oil-based eye cosmetics. Mascara is an eye cosmetic that can impressively produce the eye area by thickening, lengthening, or curling the eyelashes, and eyebrow makeup is an eye cosmetic that has effects such as adjusting the color of the eyebrows, setting the hair growth direction, and changing the impression of the whole face. These oil-based eye cosmetics are required to have good water resistance, oil resistance, and makeup retention in order to maintain the curled or set state. Therefore, it is common to blend a silicone compound having high water repellency, excellent water and oil resistance, and no stickiness and a light feel in use as an oil thickener.

[0003] For example, Patent Document 1 describes that by using a silicone emulsifier and a silicone-modified polysaccharide compound in combination as an oil thickener, a high thickening effect can be exerted on oil components including silicone oil, and an oily composition having no stickiness and a good feel in use can be obtained. A mascara cosmetic is disclosed as an example of the cosmetic, and it is described that it has a light elongation, is easy to adhere to the eyelashes, has a non-sticky feel in use, is difficult to undergo secondary transfer, and has good makeup retention.

[0004] Further, Patent Document 2 describes that an oil-based cosmetic containing a specific silicone-modified polysaccharide compound, a silicone emulsifier, an organically modified clay mineral, a carbonate ester, and a wax is excellent in adhesion, excellent in the effect of making the eyelashes look long without blending fibers, and imparts a natural finish. The eyelash cosmetic of the example is described as having excellent spreadability, showing a long lash effect, and also obtaining a sufficient thickening effect.

[0005] However, since oil-based eye makeup products containing silicone compounds are excellent in water resistance and oil resistance, they are difficult to remove with cleansing agents or facial washes and may not come off unless a dedicated point makeup remover is used. Furthermore, since silicone compounds are not biodegradable, there is concern that they may accumulate in the environment for a long time, pollute the environment, and disrupt the ecosystem. In recent years, cosmetics called "silicone-free" or "non-silicone" that do not contain silicone compounds have attracted attention.

Summary of the Invention

Problems to be Solved by the Invention

[0007] An object of the present invention is to provide an oil-based eye makeup product that has sufficient water resistance, oil resistance, and makeup retention without blending a silicone compound as an oil thickener and is also excellent in detergency.

Means for Solving the Problems

[0008] As a result of intensive studies to solve the above problems, the present inventors have found that by using an organically modified clay mineral, a specific polyglycerol-based surfactant, and an oil gelling agent, sufficient water resistance, oil resistance, and makeup retention comparable to those when a silicone compound is blended as an oil thickener can be exhibited, and at the same time, an oil-based eye makeup product that can be easily removed with a commercially available ordinary full-face cleansing oil can be obtained, thus completing the present invention.

[0009] That is, the present invention is (A) Organically modified clay mineral, (B) A polyglycerol-based surfactant selected from the group consisting of polyglycerol fatty acid esters and polyglyceryl alkyl ethers (excluding polyglyceryl isostearate), and (C) An oil gelling agent The present invention relates to an oil-based eye cosmetic containing these components.

Advantages of the Invention

[0010] By having the above composition, the oil-based eye cosmetic according to the present invention has sufficient water resistance, oil resistance, and makeup retention, and can exhibit excellent detergency without blending a silicone-based oil thickener. Therefore, it can be easily removed with a commercially available ordinary facial cleansing oil without using a dedicated point makeup remover cap. In addition, since the oil-based eye cosmetic of the present invention does not contain a silicone-based oil thickener, a silicone-free (or non-silicone) cosmetic can be realized.

Embodiments for Carrying Out the Invention

[0011] The oil-based eye cosmetic of the present invention is characterized by containing (A) an organically modified clay mineral, a specific (B) polyglycerol-based surfactant, and (C) an oil gelling agent.

[0021] Although the cause is not clear, polyglyceryl isostearate is excluded from (B) polyglycerol-based surfactants because it cannot improve the detergency of the resulting oil-based eye cosmetics. Examples of polyglyceryl isostearate include polyglyceryl-6 isostearate, polyglyceryl-10 isostearate, polyglyceryl-2 diisostearate, and polyglyceryl-2 triisostearate.

[0041] The present invention will be described in more detail with reference to the following examples, but the present invention is not limited thereto. The blending amounts are shown in mass% with respect to the oil-based eye cosmetics unless otherwise specified. Before specifically explaining each example, the evaluation method adopted will be described.

[0042] <Washability> 0.3 g of each cosmetic (sample) was uniformly applied to a slide glass, 0.05 g of a commercially available cleansing oil for face washing was dropped thereon, and after standing for 1 minute, it was gently stroked 30 times with the pad of a finger and then wiped off with a tissue, and the falling condition (removal rate) of the cosmetic was examined. [Judgment Criteria] A: Removal rate is 80% or more B: Removal rate is 50% or more and less than 80% C: Removal rate is 30% or more and less than 50% D: Removal rate is 10% or more and less than 30% E: Removal rate is less than 10%

[0043] <Stability> Each cosmetic material (sample) was stored at room temperature (25°C) for 1 month, and the separation of oil and the presence or absence of white precipitation were visually confirmed. [Judgment Criteria] A: No change B: Slight separation is observed but at an acceptable level C: Separation or precipitation is observed

[0044] <Water resistance, oil resistance and makeup retention> Each cosmetic material (sample) was uniformly applied to the application surface of a tapping tester and dried to form a film. Filter paper (10 cm 2 ) with water dropped (for water resistance test), with artificial sebum dropped (for oil resistance test), and with nothing dropped (for makeup retention test) were prepared, and the application surface was tapped 30 times (N = 3) for each filter paper. After tapping, the degree of transfer to the filter paper and the presence or absence of bleeding were examined, and the water resistance, oil resistance and makeup retention were evaluated according to the following evaluation criteria. [Judgment Criteria] A: Little transfer to the filter paper and no bleeding is observed B: There is transfer to the filter paper and slight bleeding is observed but at an acceptable level C: Considerable transfer to the filter paper and bleeding is observed
