Description

Transparent makeup remover

Technical Field

The invention relates to a transparent makeup remover.

Background

For the purpose of makeup cosmetics for removing sebum dirt or oily dirt from the skin, there are commercially available emulsion (multi-phase) type makeup removers in which a surfactant is blended to remove makeup dirt by the action of the surfactant, or oily makeup removers (oil-type makeup removers) mainly containing an oily component such as an oil agent to remove oily makeup cosmetics or oily dirt by the dissolving action of the oily component, and water and oil emulsions are clouded.

The oil-based makeup remover generally has excellent cleansing performance for oil-based makeup cosmetics such as lipsticks and foundations, and the performance of mascara and the like of a type that removes a film tends to be inferior to that of a water-based makeup remover. In addition, the oil-based cleansing product takes time to rinse, and the oily component contained in the oil-based composition may leave the skin with oily and greasy feeling, which is undesirable.

On the other hand, the water-based makeup remover is excellent in washing performance, and relatively, it is pointed out that the oil-based makeup remover is inferior in cleansing performance to an oil-based makeup cosmetic excellent in durability (makeup retention effect) such as a water-repellent type.

Furthermore, it is known that an emulsion (multiphase) type makeup remover obtained by emulsifying water and oil is cloudy is likely to be separated in the future, and that the emulsion in water and oil is inferior in cleansing performance and the emulsion in water and oil is inferior in rinsing performance.

The present inventors have completed a composition comprising component A: a diester of a branched fatty acid having 14 to 22 carbon atoms and a polyglycerol, a diester of an unsaturated fatty acid having 14 to 22 carbon atoms and a polyglycerol, or both of them, component B: an ester of a fatty acid having 6 to 10 carbon atoms and a polyglycerol, wherein the ratio of the polymerization degree of the polyglycerol to the number of fatty acid bonds (the polymerization degree of the polyglycerol/the number of fatty acid bonds) is 2.0 to 4.0, and component C: 1 or 2 or more selected from diester oil of dihydric alcohol and branched fatty acid, triglyceride oil of glycerin and branched fatty acid, and diester oil of dicarboxylic acid and branched aliphatic alcohol, component D: an invention of a cleansing oil of a hydrophilic compound (patent document 1). The cleansing oil exhibits high cleansing power even in the presence of water, has excellent washability after cleansing, and is excellent in a greasy feeling in which oil is not easily left. However, since the oil-based makeup remover is an oil-type makeup remover, there is a tendency that the cleansing power for a film-forming type makeup cosmetic (film-type mascara or the like) is poor.

Transparent makeup removers are preferred for their aesthetic appearance. In terms of technology, in the makeup remover obtained by allowing oil and water to coexist, transparency means stability in a uniform single-phase state. Since emulsification does not occur, it is expected that the cleansing performance is improved as compared with an emulsion type makeup remover.

Among them, transparent makeup removers obtained by allowing oil and water to coexist have been proposed by each company.

As transparent makeup removers obtained by allowing oil and water to coexist, for example, patent documents 2 and 3 disclose makeup removers having a high oil content of 15 mass% or less of water. The cleansing performance is similar to that of an oil-based makeup remover, and the cleansing performance of the oil-based makeup remover is high and the degree of washability is relatively insufficient.

Patent documents 4 and 5 disclose transparent cosmetics for removing makeup with a high proportion of water in which the amount of oil is 10 mass% or less. The cleansing agent has characteristics similar to those of aqueous cleansing products, is excellent in the degree of easy washing, and relatively insufficient in cleansing effect.

Patent documents 6 to 9 disclose transparent makeup removers prepared by blending a large amount of a nonionic surfactant or a relatively large amount of a monohydric alcohol having 2 to 5 carbon atoms, a glycol such as butanediol or dipropylene glycol, polyethylene glycol or polypropylene glycol, or a derivative of the compound thereof as a surface active aid. A makeup remover containing a large amount of these components has a tendency to be easily rinsed, and on the other hand, there is a fear of irritation or dryness of the skin or eye irritation during use, and further, there is a problem that the skin is excessively degreased and the moisturizing feeling after cleansing is lost.

Further, in order to make the makeup remover uniform and transparent, it is important to study the selection and blending amount of polyol when blending in addition to the balance between water and oil and the selection of surfactant. That is, because not all polyols can be formulated, formulators need more effort to design transparent stable formulations. However, a substance satisfying all the requirements of transparency, stability, detergency and safety has not yet been obtained.

In addition, in aqueous makeup removers, preservation countermeasures for the composition are required. However, in recent years, the formulation of so-called preservatives such as parabens (parabens) widely used in cosmetics has become unacceptable to consumers because of skin irritation. Therefore, a makeup remover which does not contain paraben and is safe to the skin or eyes is desired.

Disclosure of Invention

In order to achieve a cleansing effect of the makeup remover and to reduce a feeling of residual oil contained in the makeup remover on the skin after washing with water, a makeup remover of a type in which oil and water coexist is effective. However, in addition to the problems described in the conventional techniques, when both water and oil are contained, the makeup remover is remarkably clouded or separated, and the appearance and performance as a makeup product are often impaired. Further, even if a makeup remover transparent at normal temperature is obtained, sometimes cloudiness or separation occurs when stored in a state of high temperature or low temperature for about 1 month.

Further, in an environment where various types of makeup cosmetics are marketed, consumer choices become various, and it becomes impossible to sufficiently remove makeup by one kind of makeup removing product.

In view of the above-mentioned circumstances, an object of the present invention is to provide a transparent makeup remover which contains water and oil, does not contain a paraben, exhibits high antiseptic properties, is transparent and stable in a wide temperature range for a makeup remover safe to the skin or eyes, has high cleansing power for all of various types of oily or aqueous makeup cosmetics (e.g., lipstick, waterproof mascara, film mascara), has little residual feeling of oil components after cleansing, and is easily rinsed with water.

The cleansing product of the present invention contains 1 or more components selected from the group consisting of glycerin, diglycerin, polyglycerin-3, polyglycerin-4, polyglycerin-5, polyglycerin-6, and polyglycerin-10 as the component (D). These ingredients act as surface active aids in the makeup remover, and improving the solubility of water and oil contributes to the transparency and stability of the makeup remover.

The cleansing product of the present invention contains the component (D) in an amount of 7 to 35% by mass, preferably 7 to 30% by mass, more preferably 8 to 25% by mass, based on the total amount of the cleansing product. If the temperature is outside this range, a transparent and temperature-stable makeup remover may not be obtained.

(E) The components: water (W)

The cleansing product of the present invention contains 13 to 47 mass% of water as component (E) with respect to the total amount of the cleansing product, in order to obtain a cleansing effect and a rinsing effect. When the water content is less than 13% by mass, there is a fear that film-type makeup cosmetics (e.g., film-type mascara) are difficult to remove. If the water content exceeds 47 mass%. There is a concern that the cleansing power of a makeup cosmetic excellent in durability (makeup holding effect) such as a waterproof makeup cosmetic (for example, a waterproof eyeliner) may be reduced. In the present invention, when the amount of water in the component (E) is in the range of 13 to 47% by mass based on the total amount of the makeup remover, any of various types of makeup cosmetics (e.g., lip liner, waterproof eyeliner, film mascara) can be removed.

The content of water in the component (E) in the present invention is preferably 13 to 47% by mass, more preferably 15 to 45% by mass.

(F) The components: antibacterial polyol

The makeup remover of the present invention contains an antibacterial polyol as the component (F). A transparent makeup remover having high cleansing power and easy rinsability, comprising the components (A) to (E) of the present invention. However, when water containing the component (E) as an essential component is used, it may be contaminated with bacteria and cause putrefaction. The antibacterial property of the makeup remover is particularly important in quality design.

The cleansing product containing the components (A) to (E) may contain parabens. However, the paraben is dissolved in water by heating, but the paraben dissolved by heating may be crystallized and precipitated depending on the storage state. Further, when the makeup remover is used, the solid matter such as parabens which may damage the skin is precipitated by the action of rubbing the skin, and the quality is remarkably deteriorated. Further, preservatives such as parabens are components which are concerned about safety to eyes or skin. Therefore, the makeup remover of the present invention contains 1 or more kinds of (F) antibacterial polyols which are highly safe and free from crystal precipitation.

The antibacterial polyol as component (F) is preferably blended with 1 or more selected from 1, 3-butanediol (hereinafter BG), dipropylene glycol (hereinafter DPG), and 1, 2-pentanediol (hereinafter pentanediol).

BG, DPG and pentanediol, which are antibacterial polyols as the component (F), are contained in an amount of 0.1 to 9.4% by mass, more preferably 0.1 to 9% by mass, and particularly preferably 5 to 9% by mass, based on the total amount of the makeup remover. When the antimicrobial polyol other than BG, DPG and pentanediol is blended, the antimicrobial polyol containing the component is preferably contained in an amount of 0.2 to 9.4 mass%, more preferably 0.2 to 9 mass%, and particularly preferably 5 to 9 mass% in total.

In the transparent makeup remover of the present invention, when 1 or more selected from BG, pentanediol and DPG is contained as the component (F), the content ratio of the component (F) to the component (D) is particularly important. As described above, the component (D) functions as a surface-active auxiliary in the makeup remover of the present invention, and improves the solubility of water and oil to contribute to the transparency and temperature stability of the makeup remover. On the other hand, BG, pentanediol and DPG as the component (F) cannot replace the function as a solvent for the oil agent shown in the component (D), and on the contrary, white turbidity or separation of the makeup remover may be caused, and therefore, the content thereof needs to be determined carefully.

It is not preferable that the component (F) contains the same amount as or more than the component (D).

(D) The component (D) and the component (F) are preferably contained in a mass ratio of 10:9.4 to 100:1, more preferably 10:9 to 100:1, still more preferably 10:8 to 100:1, and particularly preferably 10:7 to 100: 1.

When the component (F) is contained in this manner, the transparent makeup remover having the effect of containing the component (D), that is, stable coexistence of water and oil, transparency, excellent temperature stability, and a high cleansing effect can be obtained, and an appropriate antibacterial effect can be imparted to the composition. If the amount is outside this range, the composition may become unstable due to the component (F), and the composition may be clouded or separated.

(preparation of optional Components)

In addition, various materials commonly used in cosmetics may be blended in the transparent makeup remover of the present invention within a range that does not impair the effects of the present invention. Can be formulated into pH regulator, neutralizer, antioxidant, perfume, colorant (such as cyanocobalamin, (chlorophyllin/copper) complex), and cosmetic component (such as herba Rosmarini officinalis extract).

The transparent makeup remover of the present invention is designed into various dosage forms in consideration of usability and feeling of use. Specifically, the liquid form or gel form.

Examples 1 to 18 and comparative examples 1 to 13

The compositions of examples 1 to 18 of the makeup remover of the present invention (table 1) and the compositions of comparative examples 1 to 13 (table 2) are shown below, and the features and effects of the present invention will be described in further detail by way of test examples of the makeup remover having the compositions.

1. Preparation of makeup remover

Makeup removers of the compositions of examples 1 to 18 (table 1) and comparative examples 1 to 13 (table 2) were prepared by a conventional method.

2. Evaluation test method

Each of the makeup removers of examples and comparative examples was evaluated by the following method.

< appearance Observation (transparency) >)

(a) Appearance immediately after preparation

The prepared makeup remover was filled in a transparent glass bottle (sample bottle) with a screw cap having a diameter of 30mm, and the container was seen through from the side at room temperature (RT, 25 ℃), immediately after preparation and after the lapse of storage period, and the transparency was visually evaluated.

(evaluation Standard of transparency)

And (3) transparency: 10 pound text can be read through the container from the side

White turbidity: 10 pound text cannot be read through the container from the side

Separation: in a separated state

(b) Appearance after stability test (stability)

The sample bottles containing the test specimens, which were transparent in appearance immediately after the preparation, were stored in a thermostatic chamber at 5 ℃, 25 ℃, 40 ℃ and 50 ℃ for 1 month as a stability test. After 1 month of storage, the appearance was again visually observed according to the above transparency standard.

The samples having a separated appearance state immediately after the production were subjected to no stability test, and the evaluation columns in tables 1 and 2 below show "-".

< washability (measurement of volume-standard mean particle diameter of emulsified particles) >)

The makeup remover used in the test was diluted with water in such a manner as to reach 0.1% to prepare an O/W type emulsion composition. The particle size distribution of the emulsified particles in the emulsified composition was measured by dynamic light scattering using ELSZ-1000 (available from Otsuka Denshi Co., Ltd.), and the volume-based average particle size was measured. This emulsified particle diameter (volume-based average particle diameter) was used as an evaluation index of washability.

In addition, preliminary tests were carried out in advance on the relationship between the volume-standard average particle diameter of the cleansing liquid and the degree of easy-washing of the oily component, and the following results were obtained.

(1) When the emulsified particle diameter exceeds 300nm, oily feeling remains on the skin

(2) When the emulsified particle size is 101 to 300nm, the detergent can be quickly and cleanly washed

(3) When the emulsified particle size is 100nm or less, more rapid and refreshing rinsing can be achieved

In addition, "-" indicates that the volume-based average particle diameter of the diluted makeup remover was not measured.

< easy washability (sensory evaluation) >)

1 trained sensory evaluation person evaluated the degree of easy washing with water after applying the makeup remover of the present invention to the inner side of the upper arm.

(evaluation criteria)

O: the skin is easy to wash without residual oily feeling

X: residual oily feeling on skin after washing

< evaluation of detergency (evaluation of easy removal of cosmetic soil based on sensory test) >

Tests were conducted for ease of removal of lipstick, waterproof eyeliner, and film mascara.

Trained sensory evaluators actually used each cosmetic for evaluation. That is, the sensory evaluation person applied makeup using a makeup product as a cleaning target, and after 1 hour, removed makeup using a makeup remover and fingers as evaluation targets indoors. After washing with water, the water droplets were gently wiped off with a towel, and the removal of makeup dirt was visually observed.

The cosmetics used were as follows.

Waterproof type eyeliner: master Liner Creamy Pensil BK-1

(Meibao lotus niu York system)

Film type mascara: perfect Mascara r21

(manufactured by Airan of Kabushiki Kaisha)

(evaluation criteria)

O: cosmetic soil is removed substantially cleanly

And (delta): little residue of makeup dirt

X: obvious residue of makeup dirt

< preservation efficacy test >

Based on the preservation efficacy test method established in the japanese pharmacopoeia, preservation tests were carried out using Escherichia coli (Escherichia coli), Pseudomonas aeruginosa (Pseudomonas aeruginosa), and Staphylococcus aureus (Staphylococcus aureus), and the antibacterial effect was evaluated (the test method follows the japanese pharmacopoeia). There was no problem with either bacterium in the preservation efficacy test. The table is reported as "decrease". In addition, in the storage efficiency test, the "increase" judged as a problem was not found in example 1.

< critic test >

The critic trial (home test) was performed at home by 20 female critics. For each commentator, the following instructions are issued: makeup was applied in the morning with makeup (lipstick, water-proof eyeliner, film mascara, all as in the above sensory test) dispensed simultaneously with the test article, and the test article was applied at night when makeup was removed. The amount and the number of times of use of the test article are not particularly limited. The evaluation was carried out in the freely described manner. For eye irritation, either "with" or "without" eye irritation is selected. Example 1, which answered "yes" in the critic trial, also did not. In the table, "none" is recorded in the item of eye irritation.

The makeup removers of examples 1 to 18 were all transparent in appearance. On the other hand, the makeup removers of comparative examples 1 to 13 did not obtain a sample having a transparent appearance immediately after preparation. The samples of comparative examples 1 to 3 and 5 were in a cloudy state, and in this case, it was judged that the cosmetic makeup remover intended by the present invention was not satisfactory, but a stability test was conducted in a constant temperature room at 5 ℃, 25 ℃, 40 ℃ and 50 ℃.

(b) Appearance after stability test (transparency, separation)

When the cleansing products of examples 1 to 18 were stored in a thermostatic chamber at 5 ℃, 25 ℃, 40 ℃ and 50 ℃ for 1 month and then were taken out to evaluate the transparency, all of the cleansing products remained transparent. On the other hand, the makeup removers of comparative examples 1 to 3 and comparative example 5 were each separated after being stored for 1 month in any of the temperature ranges of 5 ℃, 25 ℃, 40 ℃ and 50 ℃.

When the compositions of examples 1 to 18 were compared with those of comparative examples 3 to 7, the compositions of comparative examples 3 to 7 were each a composition containing BG or DPG of a polyol in place of glycerin, diglycerin, or polyglycerin, which are the polyols of the component (D) in examples 1 to 18. However, this composition causes cloudiness or separation of the makeup remover from immediately after preparation. That is, it was found that water, oil and a surfactant are transparent, and glycerin, diglycerin and polyglycerin as the component (D) of the polyol are required to be contained in the compositions of examples 1 to 18.

Further, it was found that in the makeup remover containing water, oil and a surfactant, even if the polyol is contained, only BG and DPG are contained, clouding and separation occur, and the transparency and the stabilization of the composition cannot be contributed (refer to the appearance evaluation of comparative examples 3 to 7 immediately after the preparation).

Furthermore, comparative examples 1 to 7 have compositions containing components (A), (B), (C) and (E) and not containing component (D). Wherein comparative examples 1 and 2 were compositions containing no BG or DPG. On the other hand, the compositions of comparative examples 3 to 7 contain BG or DPG. When the results of the appearance evaluation of the composition immediately after the production were compared, comparative examples 1, 2, 3 and 5 were only clouded, but comparative examples 4, 6 and 7 were separated from each other immediately after the production.

On the other hand, in examples 1 to 18, although BG or DPG was contained, neither clouding nor separation occurred in the transparency and storage stability test immediately after the production. Namely, it was found that the transparency and the storage stability are excellent. In the examples, the mass ratio of the two components (D) and (F) is in the range of 10:9 to 20: 5.

< washability (measurement of volume-standard mean particle diameter of emulsified particles >

The volume-standard average particle diameters of the emulsified particle diameters of the diluted solutions measured for the makeup removers of examples 1 to 14 and 18 are shown in table 1. The minimum value was 66.7nm (example 9) and the maximum value was 244.2nm (example 12). Half of the 15 cases (examples 2, 3, 4, 5, 9, 10, 11, and 18) were evaluated to obtain an evaluation of "more rapid and refreshing rinsing was possible when the emulsified particle size was 100nm or less". In the remaining 7 examples (examples 1, 6, 7, 8, 12, 13 and 14), the evaluation of "quick and refreshing rinsing with emulsion particle size of 101 to 300 nm" was obtained.

< easy washability (sensory evaluation) >)

The evaluation results of the sensory evaluation personnel are shown in table 1.

All makeup removers of examples 1-18 received a ". smallcircle evaluation: evaluation of easiness to rinse without leaving oily feeling on the skin. The result of the easy-to-rinse degree (sensory evaluation) was consistent with the judgment of the measurement result of the volume-standard average particle diameter.

< evaluation of detergency (evaluation of ease of removal of cosmetic soil based on sensory evaluation) >

The evaluation results of the degree of easy removal of lipstick, waterproof eyeliner, and film mascara are shown in table 1.

All of the makeup removers of examples 1 to 18 were evaluated as "o", and it was confirmed that an evaluation of "makeup dirt was removed substantially cleanly" was obtained.

< preservation efficacy test >

By tests based on the criteria of the japanese pharmacopoeia, any of the species escherichia coli, pseudomonas aeruginosa, and staphylococcus aureus was "reduced", and was judged to be no problem.

< critic test >

When the makeup removers of examples 9, 10, 13, and 14 were handed over to 20 female critics and the critic's test (home test) was performed at home, the evaluation was very high in the comment field that the cleansing power was not satisfactory, and the film mascara, the water-resistant eyeliner, the foundation, and the lipstick were well removed. Further, report 1 in which irritation to the skin or eyes was felt was also absent.

Various types of makeup cosmetics are on the market, the choice of which is left to the consumer's taste. Since the transparent makeup remover of the present invention is prepared with water stably in advance, a consistently stable and excellent cleansing effect can be obtained regardless of the type of makeup cosmetic selected by the consumer or the use situation (bathroom with a high risk of water being mixed in/room without water being mixed in) in which the consumer performs cleansing action (makeup removal). In particular, in the conventional art, for eye makeup that is difficult to remove, complicated makeup operations such as removing makeup using a makeup remover dedicated to eye makeup removal and removing makeup using another makeup remover for the entire face have to be performed. However, in the makeup remover of the present invention, all makeup cosmetics of different types can be removed by only 1 makeup remover. Such a cleansing effect cannot be considered in the makeup remover of the prior art, and the present invention achieving the effect is epoch-making.

Further, the makeup remover of the present invention has a transparent appearance and is stable even when the antibacterial polyol is blended, and is highly safe because of low irritation to the eyes or skin.

Examples 19 to 27 and comparative examples 14 to 15

The optimum amount of water as component (E) of the present invention was investigated in detail. The details of the tests and the results of comparative studies based on the compositions of examples 19 to 27 and comparative examples 14 to 15 (Table 3) are shown.

1. Preparation of makeup remover

The makeup removers of the compositions of examples 19 to 27 and comparative examples 14 to 15 (Table 3) were prepared according to a conventional method.

2. Evaluation test method

Each of the cosmetics removers was evaluated by the same test method as that performed for the cosmetics removers of examples 1 to 18 and comparative examples 1 to 13.

The following test items were carried out: "< appearance observation (transparency) >, (a) appearance immediately after preparation, (b) appearance (stability) after stability test", "< washability (measurement of volume standard average particle diameter of emulsified particles) >", "< ease of washing (sensory evaluation) >", "< evaluation of detergency (evaluation of ease of removal of makeup soils based on sensory evaluation) >".

3. Evaluation results

The evaluation results are shown in the lower panel of table 3 below.

[ Table 3]

Examples 19 to 27 had compositions of transparent makeup removers containing 7 to 9.6 mass% of component (A), 6.4 to 9 mass% of component (B), 23.4 to 44 mass% of component (C), 8 to 25 mass% of component (D), 15 to 44.99 mass% of component (E), and 5 to 8 mass% of component (F).

On the other hand, comparative example 14 contained 9.6 mass% of component (a), 6.4 mass% of component (B), 44 mass% of component (C), 25 mass% of component (D), 5 mass% of component (F), and 10 mass% of component (E). Comparative example 15 contained 9.6 mass% of component (a), 6.4 mass% of component (B), 20 mass% of component (C), 9 mass% of component (D), 5 mass% of component (F), and 50 mass% of component (E).

< appearance Observation (transparency) >)

(a) Appearance immediately after preparation

The makeup removers of examples 19 to 27 were all transparent in appearance. In addition, the makeup remover of comparative example 14 was also transparent. On the other hand, the appearance of comparative example 15 immediately after the production was opaque and white. The samples of examples 19 to 27 and comparative example 14 were subjected to a stability test of storage in a constant temperature room at 5 ℃, 25 ℃, 40 ℃ and 50 ℃.

(b) Appearance after stability test (stability)

When the makeup removers of examples 19 to 27 and the makeup remover of comparative example 14 were stored in a thermostatic chamber at 5 ℃, 25 ℃, 40 ℃ and 50 ℃ for 1 month and then were taken out to evaluate the transparency, all the makeup removers maintained the transparency.

The volume-based average particle diameters of the emulsified particles measured for the makeup removers of examples 19 to 27 and the makeup remover of comparative example 14 are shown in table 3. The evaluation of "when the emulsified particle size is 100nm or less, more rapid and refreshing rinsing" was obtained in 2 of the examples 9 (examples 21 and 25). The remaining 7 examples (examples 19, 20, 22, 23, 24, 26, and 27) and comparative example 14 also showed the volume-based average particle size of the emulsified particles evaluated as "quick and clean rinsing when the emulsified particle size was 101 to 300 nm".

< easy washability (sensory evaluation) >)

The evaluation results of the sensory evaluation personnel are shown in table 3.

All of the makeup removers of examples 19 to 27 and comparative example 14 were evaluated for "O": evaluation of easiness to rinse without leaving oily feeling on the skin. The result of the easy-to-rinse degree (sensory evaluation) was consistent with the judgment of the measurement result of the volume-standard average particle diameter.

The evaluation results of the degree of easy removal of lipstick, waterproof eyeliner, and film mascara are shown in table 3.

All of the makeup removers of examples 19 to 27 were evaluated as "o", and it was confirmed that makeup stains were removed almost cleanly. However, the makeup remover of comparative example 14 could not remove the dirt of the film type mascara, and this test gave an "x" evaluation.

The following conclusions can be drawn from the above test results.

That is, as is clear from the makeup remover of comparative example 14 that the film type mascara could not be removed, the content of water as the (E) component must exceed 10 mass% in order to remove the film type mascara dirt.

It is considered that, in comparative example 15, the content of water as the component (E) must be less than 50% by mass so as not to cause white turbidity or the like in the makeup remover.

On the other hand, the good evaluation was obtained from the transparency immediately after the preparation and also the transparency after the storage test in examples 19 to 27, and the easy washability in the sensory evaluation and the cleaning effect by the sensory evaluation, which is considered to be the effect due to the water content of the component (E) being in the range of 15 to 44.99 mass%.

Quantitative evaluation test of cleaning ability of Water-proof eyeliner and film-type mascara

In order to accurately measure the cleansing power of the makeup removers of examples 21 to 27 and comparative example 14 with respect to the water-proof eyeliner and film mascara, quantitative cleansing power measurement was performed (see fig. 1 and 2 for the results).

< test method >

In this test, the cleansing rate of the makeup cosmetic was obtained from the color difference, and the cleansing power was evaluated.

(calculation formula of cleansing Rate of cosmetic preparation)

A color value 1 of the white artificial leather before application of the makeup cosmetic (hereinafter referred to as "makeup"), a color value 2 of the test object after application of the makeup cosmetic, and a color value 3 of the test object after cleaning with the test sample were measured with a color difference meter (device name: CM-2600d, manufactured by Konica Minolta Co., Ltd.), a color difference (. DELTA.Ea; color difference before and after application,. DELTA.Eb; color difference before and after cleaning) was obtained from the measurement values, and a makeup cleaning ratio (%) was further obtained according to the following calculation formula.

Further, (. DELTA.L) (. DELTA.E)²+Δa²+Δb²)^1/2。

Cosmetic cleansing ratio (%). DELTA.Eb/. DELTA.Ea.times.100

The higher the value of the makeup cleansing ratio (%) is, the higher the cleansing power can be judged.

Specifically, this is performed as follows.

< method for evaluating detergency >

(1) 0.005g of water-proof eye line or film type mascara was applied and dried for 30 minutes within a range of 1cm in diameter of 3cm × 6cm of white artificial leather for which the measurement of color value 1 was previously completed. This was used as a test specimen.

As a waterproof eyeliner, Master Liner Creamy Pensil BK-1, NY, Meibaogan was used.

Further, as the film type Mascara, an artemisia natural Perfect Mascara r21 was used.

(2) The color value 2 of the test specimen thus prepared was measured using a color difference meter (apparatus name: CM-2600d, manufactured by Konica Minolta).

(3) 0.1ml of the test specimen prepared in (1) above was dropped on the test specimen, and the specimen was wiped with a finger at a speed of 1 time per 1 second for 20 times.

(4) The test specimen was thoroughly washed with water and dried.

(5) The color value 3 of the dried test specimen was measured by a color difference meter.

(6) And obtaining the cleaning rate (%) of the waterproof eyeliner or film mascara according to the calculation formula of the makeup cleaning rate.

Results of the cleaning force measurement test

The results of the test for the cleansing power of the waterproof type eyeliner or the film type mascara are shown in fig. 1 and 2.

As shown in FIG. 1, the cleansing products of examples 21 to 27 and comparative example 14 all had high cleansing performance of 80% or more for the waterproof eyeliner.

On the other hand, with respect to the film-formed mascara, the difference in cleaning force between the approved example and the comparative example is large. That is, as shown in fig. 2, examples 21 to 27 exhibited a cleaning effect of 80% or more with respect to the film-formed mascara, and exhibited a strong cleaning effect. Comparative example 14 was extremely low in cleansing power relative to film-type mascara, and exhibited only 10% or less cleansing power. The test results are very consistent with the sensory test results.

As is clear from the above-mentioned tests using examples 21 to 27 and comparative example 14, in the makeup remover of the present invention, the content of water as the component (E) must exceed 10% by mass relative to the total amount of the makeup remover in order to clean the film-type mascara. Further, it is judged that the optimum content of water in the component (E) is 13 to 47 mass%, more preferably 15 to 45 mass% in order to maintain the transparency stability by storage.

Studies of maximum content of component (F) (based on the studies of comparative examples 16 to 31)

In order to confirm the maximum content of the antibacterial polyol as the component (F) of the present invention, the composition of comparative examples 16 to 31 (Table 4) was examined. The test results are shown for illustration.

1. Preparation of makeup remover

The makeup removers of comparative examples 16 to 31 (compositions of table 4) were prepared by a conventional method.

Comparative examples 16 to 29 had compositions in which the content of components (a) to (E) was adjusted to fall within the range suitable for the makeup remover of the present invention, and the content of the antibacterial polyol of component (F) was adjusted to 10 to 30 mass%. Further, the antibacterial polyol can be produced by appropriately increasing or decreasing the contents of cetyl ethylhexanoate as component (C), glycerin as component (D), and water as component (E) within an allowable range for the increase in the content of the antibacterial polyol.

In addition, the contents of the components (a) to (D) in the comparative examples 30 and 31 were adjusted to an appropriate content based on the composition of the makeup remover of the present invention so as to reduce the water content of the component (E) to 10 mass% and increase the BG or DPG of the component (F) to 30 mass%. Thus, the content of the antibacterial polyol is changed.

2. Evaluation test method

Each test sample was evaluated by the same test method as the evaluation test of the makeup removers of examples 1 to 18 and comparative examples 1 to 13.

The test items were evaluated for "< appearance observation (transparency) >, (a) appearance immediately after production, (b) appearance (stability) after stability test)," < washability (measurement of volume standard average particle diameter of emulsified particles) > ".

3. Evaluation results

The evaluation results are shown in the lower panel of table 4 below.

[ Table 4]

< appearance Observation (transparency) >)

(a) Appearance immediately after preparation

The makeup remover of the composition of comparative example 19 alone was a transparent makeup remover. On the other hand, the makeup removers of the compositions of comparative examples 16 to 18 and 20 to 31 were opaque and white in appearance immediately after preparation. Therefore, the samples other than comparative example 19 were judged to be defective, and only the stability test was conducted in which the samples of comparative example 19 having a transparent appearance were stored in a constant temperature chamber at 5 ℃, 25 ℃, 40 ℃ and 50 ℃.

(b) Appearance after stability test (stability)

The makeup remover of comparative example 19, which was subjected to the stability test, was stored in a thermostatic chamber at 5 ℃, 25 ℃, 40 ℃ and 50 ℃ for 1 month, and then was taken out and evaluated for transparency. The transparency was maintained at a temperature of 5 ℃ and 25 ℃, but the separation occurred at a temperature of 40 ℃ and 50 ℃. Therefore, comparative example 19 failed to achieve the desired stability and was judged as a failure.

Only the makeup remover of comparative example 19 which was transparent immediately after the preparation was measured. The volume-standard average particle diameter of the emulsified particle diameter of the diluted solution is 51.2nm as shown in Table 4.

In the above, makeup removers having the compositions of comparative examples 16 to 31 were prepared, and tests were conducted to confirm the limit of the maximum content of the antibacterial polyol as the component (F). However, it is difficult to contain the antibacterial polyol as the component (F) in an amount of 10 mass% or more. That is, it is judged that it is not preferable to contain the antibacterial polyol as the component (F) in an amount of 10 mass% or more in order to prepare a transparent makeup remover having high storage stability which is an object of the present invention.
