Description

The present invention relates to a warm cleansing cosmetic.

The main purpose of makeup remover cosmetics is to remove makeup cosmetics such as lipsticks, foundations, eye shadows, and mascara. As the form, various types such as an emulsified cream type, a milky type, an aqueous liquid type, a gel type, and an oily liquid type solidified with a gelling agent are commercially available.
Among these cosmetics, oily liquid type cleansing cosmetics having a high cleansing effect tend to be preferably used.

Oily liquid type cleansing cosmetics are used by taking a small amount on the palm and massaging the face and lips. At this time, a warming cleansing cosmetic having a heat-generating effect that makes the skin feel warm with the massage is preferred. Warm cleansing cosmetics can be expected to have effects such as promoting blood circulation in the skin, improving cleansing action, and promoting absorption of medicinal ingredients. It is also known that it is particularly effective to open pores to remove make-up cosmetics and to soften the skin to improve its compatibility with dirt and cleansing properties.
The heat generation mechanism associated with the massage uses the heat of chemical reaction (Patent Document 1), the heat of hydration of alcohol or polyhydric alcohol (Patent Document 2), and the heat of hydration of inorganic salts (Patent Document 2). Patent Document 3), those utilizing the heat of hydration of an inorganic powder such as zeolite (Patent Document 4), and those using a combination thereof (Patent Document 5).
However, each of these prior arts also points out its own unique problems. When a chemical reaction is used as in Patent Document 1, it is necessary to separate the two components to be reacted, and it is often necessary to prepare at the time of use depending on the dosage form. In addition, it is necessary to consider in advance the effects of ions generated by chemical reactions on the skin. When the heat of hydration of alcohol or polyhydric alcohol is used as in Patent Document 2, it is necessary to add a large amount of these components in order to give a desired warmth feeling, and as a result, the cleaning effect is lowered or used. Poor feeling occurs. When the heat of hydration of inorganic salts and inorganic powders is used, these inorganic salts and inorganic powders are mixed in a high concentration, so that these particles cause scratches on the skin during skin massage, which has an adverse effect on the skin. It has been pointed out.
At present, there is no cleansing cosmetic that has both a satisfactory cleansing effect and a skin warming effect.

The cleansing cosmetic of the present invention gives a warm feeling by the heat of hydration of the polyhydric alcohol, and has a feature that both the warm feeling and the cleansing power are compatible depending on the type and blending ratio of the polyhydric alcohol.

The compounding ingredients of the present invention will be described.
<(A) Oil agent>
An oil agent is a compounding ingredient necessary for dissolving and cleaning oily make-up cosmetics. Any oil that can be added to cosmetics and has a cleansing effect can be added.
Examples of the oil agent (A) to be blended in the present invention include diisononanoic acid 1,3-butylene glycol, tri2-ethylhexanoate glyceryl, di2-ethylhexyl succinate, di (caprylic acid / capric acid) propanediol, and tri. It is particularly preferable to add glyceryl (caprylic acid / capric acid).

The blending amount of the oil agent is preferably 45 to 80% by mass with respect to the total amount of cleansing cosmetics from the viewpoint of achieving both cleansing power and warmth.

<(B) Glycerin / Diglycerin>
The cleansing makeup of the present invention contains 7 to 17% by mass of glycerin and / or diglycerin. When the blending amount of glycerin and / or diglycerin is less than 7% by mass, a preferable warming effect cannot be obtained, and when it exceeds 17% by mass, the cleansing power is lowered.

<(C) PEG / PPG / Polybutylene Glycol-8 / 5/3 Glycerin, PPG-9 Diglyceryl, Tripropylene Glycol, Isoprene Glycol, PPG-10 Methyl Glycol>
The cleansing cosmetics of the present invention include PEG / PPG / polybutylene glycol-8 / 5/3 glycerin, PPG-9 diglyceryl, tripropylene glycol, isoprene glycol and PPG-10, which are polyhydric alcohols as the component (C). Formulate 1 or more selected from methyl glucose.
The component (B) and the component (C) are blended so that the mass ratio of (B) / (C) exceeds 2.
It is preferable that the component (C) is blended in an amount of at least 3% by mass or more.

<(D) Polyglycerin fatty acid ester of HLB 10-12>
The cleansing cosmetic of the present invention contains 10 to 30% by mass of (D) HLB 10 to 12 polyglycerin fatty acid ester as a surfactant.

It is preferably 1 or more selected from HLB 11.6) and hexaglyceryl dicaprate (HLB 10.2).

Further, in the cleansing cosmetic of the present invention, it is preferable that water is not substantially contained because both cleansing power and warmth can be stably obtained. However, many of the ingredients (including optional ingredients) that can be blended in cosmetics contain water in the raw materials. In the present invention, substantially free of water means that the amount of water contained in each component is adjusted so that the total amount (content) of water is less than 1% by mass, which is more preferable. It is more preferable that the amount of water is 0.4% by mass or less.

In the cleansing cosmetics of the present invention, various ingredients commonly used in cosmetics can be arbitrarily blended as long as the effects of the present invention are not impaired. For example, components other than the above (A), (B), (C), (D); oil, alcohol, thickener, natural polymer, synthetic polymer, saccharide, various extracts, surfactant, moisturizing agent. Agents, antioxidants, buffers, preservatives, pigments, fragrances, pH adjusters and the like can be appropriately blended.

The cleansing cosmetic of the present invention can be prepared by a known production method, and each component is weighed and then stirred and mixed to obtain a cleansing cosmetic.
The term "transparent" as used in the present invention means that a glass test tube having a diameter of 3.5 cm or a bottle with a screw cap is filled with cleansing cosmetics and printed on a paper installed on the opposite side of the test tube or bottle to have a width of 3 mm. The black line is transparent enough to be seen without bleeding or fading.

Hereinafter, test examples of cleansing cosmetics prepared with the compositions of Examples and Comparative Examples will be shown, and the warm-feeling cleansing cosmetics of the present invention will be specifically described.
1. 1. Evaluation method (1) Appearance observation (transparency, uniformity)
The prepared cleansing cosmetics were filled in a transparent glass bottle, and the uniformity and transparency were evaluated by observing the appearance. In this test, all the uniforms were transparent by appearance observation, so either transparent or separated was shown in the table. That is, what is described as transparent also means that the composition was uniform. In addition, the cleansing power and warmth of the separated products were not evaluated, and "-" was shown in the table.

(2) Cleansing power ・ Objects to be removed Lipstick (oil-based) and eyeliner (film-forming property) were selected as makeup cosmetics to be removed. As the lipstick, "FANCL Moisture Rouge S Color No. 82 Elegant Pink" was used. As the eyeliner, "Maybelline New York Masterliner Creamy Pencil Color No. BK-1 Rich Black" was used. This eyeliner forms a coating and has a waterproof function.

-Test method of cleansing power An appropriate amount of lipstick or eyeliner was applied to white artificial leather and dried in a drying room at 25 ° C. for 30 minutes. Then, 0.1 ml of cleansing cosmetics was added dropwise, rubbed with a finger at a rate of one reciprocation per second 20 times, rinsed with water, and dried. The makeup residue after washing was visually confirmed.
The cleansing power was evaluated by ○, △, and × according to the following criteria.
◯: Makeup cosmetics have been completely removed.
Δ: A slight residual make-up cosmetic is observed.
×: Makeup cosmetics have hardly fallen.

(3) Evaluation of warmth The evaluation was made by two skilled and specialized panelists.
The warmth (warmth) felt when 1 g of cleansing cosmetic was taken on the palm and immediately applied to the cheeks was repeatedly evaluated three times (N = 3). The warmth was evaluated by ○, △, and × according to the following criteria.
◯: Feel a sufficient warmth when using.
Δ: The feeling of warmth felt during use is not sufficient.
×: No feeling of warmth when used.
In addition, although the evaluations of the two people did not differ between ○ and ×, if the evaluations of the two people were different between ○ and △, or if the evaluations were different between △ and ×, All of them were judged to be △ and listed in the table.

2. 2. Test Examples for Evaluating Cleansing Cosmetics (1) Examination of Ingredients In order to examine the composition that has both cleansing power and warmth effect, cleansing cosmetics with the composition shown in Table 1 below are prepared by a conventional method. did. In addition, each compounding table shown below is shown by the mass% of the compounding component per cleansing cosmetic.

When the cleansing cosmetics having the compositions shown in Table 1 were tested, the object of the present invention was achieved only in Example 1 containing all of the components (A), (B), (C) and (D).
The compositions of Comparative Examples 1, 4 and 6 were transparent and had high cleansing power, but no warm feeling was felt because the component (B) glycerin was not blended.
The compositions of Comparative Examples 2, 3 and 5 did not contain any or both of the component (C) and the component (D), but did not result in a transparent and uniform cleansing cosmetic.
The composition of Comparative Example 7 was a composition in which 1% by mass of water was blended with the composition of Example 1, but it became clear that when 1% by mass of water was blended, the feeling of warmth was not felt.

(2) Examination of the blending amount of the component (B) A test was conducted on a cleansing cosmetic having the composition shown in Table 2. Here, glycerin was used as the component (B), and PEG / PPG / polybutylene glycol-8 / 5/3 glycerin was used as the component (C).

Examples 1, 2 and 3 were all transparent and uniform cleansing cosmetics. And Examples 1, 2 and 3 were all warm cleansing cosmetics which achieved the object of this invention.
On the other hand, the compositions of Comparative Examples 8 and 9 include all of the components (A), (B), (C), and (D), but the blending amounts of the component (B) are 20% by mass and 21% by mass. The composition has a relatively large amount. In Comparative Examples 8 and 9, transparent and uniform cleansing cosmetics could be prepared, but the eyeliner remained slightly on the skin and the cleansing power was evaluated as Δ. And the feeling of warmth felt at the time of use was not enough, and it was evaluated as △. It was found that when the amount of the component (B) was large, the cleansing power tended to decrease and the feeling of warmth tended to weaken.

Further, the composition of Comparative Example 10 does not contain any of the components (B) and (C), and the composition of Comparative Example 11 contains all of the components A, B, C and D, but the component (B) is contained. The composition is relatively small at 4.5% by mass, and the component (C) is also relatively small at 1.5% by mass. A transparent and uniform composition was obtained in both Comparative Examples 10 and 11, but no warmth was felt (× evaluation).
Based on the above, in the composition containing the constituent components ((A), (B), (C), (D)) of the present invention, the composition is transparent, uniform, has excellent cleansing power, and gives a feeling of warmth. It was found that the appropriate concentration range of the component (B) needs to be 7 to 17% by mass, and the cleansing power and the feeling of warmth can be more reliably achieved in the concentration range of 7 to 14% by mass.

(3) Examination of components (B) and (C) Further studies on substances that can be used for the components (B) and (C). The cleansing cosmetics prepared with the compositions shown in Table 3 below were evaluated by the same method as in the above test. The evaluation results are shown in the lower part of Table 3.

Example 4 is a prescription using diglycerin instead of glycerin as the component (B). With this formulation, it was possible to achieve both the cleansing power and the feeling of warmth, which are the objects of the present invention.
The compositions of Examples 5, 6, 7 and 8 contain glycerin as the component (B) and the components shown in Table 3 as the component (C) (PPG-9 diglyceryl, tripropylene glycol, isoprene glycol and PPG-). It is a mixture of 10 methylglucose). Even when these polyhydric alcohols were used, both excellent cleansing power and warmth could be achieved.
In Comparative Examples 12, 13 and 15, a uniform transparent composition could be prepared, but a sufficient warmth was not obtained (Δ evaluation).
In Comparative Examples 14 and 16, uniform and transparent cleansing cosmetics could be prepared, but a feeling of warmth was not obtained (× evaluation).
From this test, it was found that glycerin and diglycerin are suitable as the component (B), and it is important to select the component (C) in order to enhance the warming effect of the component (B). When glycerin or diglycerin is used as the component (B), PEG / PPG / polybutylene glycol-8 / 5/3 glycerin, PPG-9 diglyceryl, tripropylene glycol, isoprene glycol and PPG-are suitable as the component (C). It turned out to be 10 methyl glucose.

(4) Examination of (A) component The substances that can be used for the oil agent of (A) component were examined. The cleansing cosmetics prepared with the compositions shown in Table 4 below were evaluated by the same method as in the above test. The evaluation results are shown in the lower part of Table 4.

As shown in Table 4, the components (A) include diisononanoic acid 1,3-butylene glycol, tri2-ethylhexanoate glyceryl, di2-ethylhexyl succinate, di (caprylic acid / capric acid) propanediol, and tri (caprylic acid). / Caprylic acid) Regardless of which of the glyceryl oils was added, a cleansing cosmetic that was transparent and uniform, had excellent cleansing power and a warm feeling was obtained.

(5) Examination of component (D) The components that can be used for the surfactant of component (D) were examined. The cleansing cosmetics prepared with the compositions shown in Table 5 below were evaluated by the same method as in the above test. The evaluation results are shown in the lower part of Table 5.

In Examples 14, 15, 16, 17, 18, and 19, decaglyceryl diisostearate (HLB11.1), decaglyceryl dioleate (HLB11.9), and eikosaglyceryl octaisonononanoate (HLB11.9), which are classified as nonionic surfactants, are classified. HLB11.8), Eikosaglyceryl hexacaprylate (HLB11.6), and Hexaglyceryl dicaprate (HLB10.2) are blended in a total amount of 10 to 30% by mass. All of the cleansing cosmetics having these compositions have the action and effect (transparency, excellent cleansing power, warmth) that are the objects of the present invention.
On the other hand, Comparative Example 17 was a formulation containing 20% by mass of polyoxyethylene glyceryl triisostearate (20EO.) Of HLB8, but it was separated. Polyoxyethylene glyceryl triisostearate (20E.O.) is known as a component that is preferably blended in cleansing cosmetics, but it could not be blended in an amount of 20% by mass.
From this test result, the surfactant suitable for the cleansing cosmetic of the present invention is a polyglycerin fatty acid ester of HLB 10 to 12, and by blending a surfactant having a specific HLB value, the surfactant can be relatively made. It was found that a transparent and uniform cleansing cosmetic can be obtained even if a large amount of 10 to 30% by mass is blended. By adopting the configuration of the present invention, it was possible to achieve both cleansing power and warmth.

(6) Examination of composition without component (C) and replacement of component (D) Cleansing cosmetics having the composition shown in Table 6 were prepared and evaluated in the same manner. The characteristic of the composition of Comparative Example 18 is that it contains a very large amount of glycerin (72% by mass) and 5% by mass of polyoxyethylene glyceryl triisostearate (20EO), which is often contained in cleansing cosmetics. That is. This composition is typical as a cleansing cosmetic having a warming effect.

In the composition of Comparative Example 18, a cleansing cosmetic having a transparency and a warm feeling was obtained, but there was no function of removing the eyeliner (× evaluation), and it was found that the desired cleansing power could not be achieved. ..

(7) Examination of the ratio of the component (B) / component (C) As described above, all of Examples 1 to 19 show a value in which the ratio of (B) / (C) in the cleansing cosmetics exceeds 2. In Table 7 below, cleansing cosmetics having the composition of Comparative Example 19 having (B) / (C) of 1 and Comparative Example 20 having (B) / (C) of 0.42 were prepared and evaluated in the same manner. The results of the work are shown.

In Comparative Example 19 in which the ratio of (B) / (C) is 1, and Comparative Example 20 in which the ratio of (B) / (C) is 0.42, transparency and cleansing power are the objects of the present invention. It was achieved. However, the feeling of warmth felt during use was not sufficient, and Comparative Example 19 was evaluated as Δ, and Comparative Example 20 was evaluated as ×. It was found that the smaller the ratio of (B) / (C) is, the less likely it is that a feeling of warmth is felt. From the above test results, it was determined that the values of (B) / (C) must exceed 2 in order to give a sufficient feeling of warmth.

(8) Skin condition after warmth evaluation test A warmth evaluation test was conducted using the cleansing cosmetics of Examples 1 to 19, but the skin of the evaluator who conducted the test suffered scratches and inflammation. I didn't. The cleansing cosmetic of the present invention was extremely mild to the skin.
