Description

Technical Field

[0001] The present invention relates to a carmine dye surface-treated with a hydrophobizing agent and a cosmetic containing the same.

Background Art

[0002] In cosmetics, inorganic pigments and organic pigments are used for the purpose of coloring effects, and various powders such as dyes are contained as organic pigments. Among the dyes, there are synthetic dyes and natural dyes. Synthetic dyes are regulated in each country, and natural dyes that are likely to fade may be used intentionally. Among the natural dyes, carmine dye obtained from the dried product of cochineal insects has high chroma and can be colored red, so it is contained in various cosmetics including makeup cosmetics. However, carmine dye is a dried product from an extract, and has unevenness in surface shape depending on the drying method. Therefore, it has poor spreading on the skin, and the smoothness during application may be impaired due to a strong scratching feeling. Furthermore, the cohesiveness between powders is high, the surface is hydrophilic, and fading tends to be promoted when it comes into contact with water. Also, due to poor dispersibility in oil agents, the color development may be poor when contained in cosmetics and aggregates may occur again. Conventionally, in order to solve these problems, many studies have been conducted on formulations. For example, a method of improving color development by combining dye compounds derived from safflower (see, for example, Patent Document 1) and a method of micronizing carmine dye (see, for example, Patent Document 2) are known.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the technology described in Patent Document 1, for example, because it is used in combination with a safflower-derived pigment, the spreadability and squeaky feeling of the cochineal pigment on the skin are not improved, and furthermore, when incorporated into cosmetics, aggregates and uneven color application were sometimes observed. Also, in the technology described in Patent Document 2, for example, although vivid colors can be realized due to the fineness of the powder, the surface area of ​​the powder becomes large, which sometimes leads to increased re-aggregation when incorporated into cosmetics. Against this backdrop, there is a need for a method for producing cochineal pigment that has a smooth feel when applied and excellent uniformity of color application, as well as for cosmetics that, when incorporated into cosmetics, do not contain aggregates, are resistant to fading, and have excellent color development.

[0005] Therefore, the present invention aims to provide a method for producing cochineal dye that has a smooth feel when applied and excellent uniformity of color, and a cosmetic product that, when contained therein, does not contain aggregates and has excellent color development. [Means for solving the problem]

[0006] In light of these circumstances, the inventors conducted diligent research and found that hydrophobic treatment using a hydrophobic treatment agent resulted in superior uniformity of color and smoothness during application. Furthermore, they discovered that incorporating hydrophobic treated cochineal dye into cosmetics improved dispersibility with oils, resulting in cosmetics with good color development and no aggregates, thus completing the present invention.

[0007] In other words, the present invention is as follows: [1] Cochineal dye that has been surface-treated with a hydrophobic agent. [2] The cochineal dye described in [1] is the cochineal dye described in [1] which contains carminic acid or its lake. [3] The hydrophobic treatment agent is the cochineal dye according to [1] or [2], which contains a dimethylpolysiloxane structure and one or more alkyl groups having C12 to C30 carbon atoms. [4] The hydrophobic treatment agent is the cochineal dye described in [1] to [3], having one or more selected from carboxyl groups and hydroxyl groups. [5] The cochineal dye according to any one of [1] to [4], wherein the average particle size D90 of the cochineal dye particles surface-treated with the hydrophobic treatment agent is less than 200 μm. [6] A cosmetic composition containing the cochineal dye described in any one of the items [1] to [5] above. [7] The cosmetic is the cosmetic described in [6], wherein the cosmetic is a makeup cosmetic. [8] A method for producing cochineal dye, in which the cochineal dye is surface-treated with a hydrophobic treatment agent, mixed with a volatile solvent, and then dried to form a fine powder. [Effects of the Invention]

[0008] The cochineal dye surface-treated with the hydrophobic treatment agent used in the present invention is hydrophobic and exhibits excellent resistance to pigment particle aggregation. Furthermore, cosmetics containing cochineal dye surface-treated with the hydrophobic treatment agent of the present invention exhibit excellent smoothness during application, uniformity of color, good color development, and resistance to aggregation. [Brief explanation of the drawing]

[0009] [Figure 1] This figure shows the (contact angle) results for Manufacturing Example 1, Manufacturing Comparative Example 1, and Manufacturing Comparative Example 3. [Modes for carrying out the invention]

[0010] The present invention will be described in detail below. In this specification, mass % may sometimes be simply written as "%", but this will mean mass %, and "~" will mean a range including the values ​​before and after it. The size of the surface-treated cochineal dye is measured by particle size distribution measurement [laser diffraction / scattering method]. Specifically, for example, in order to measure the size of the sample (powder) in the gas phase, it is forcibly dispersed using compressed air in a dry measurement unit and placed into the sample input port of a laser diffraction / scattering particle size distribution analyzer (laser diffraction / scattering particle size distribution analyzer (particle size distribution) LA-960V2, HORIBA Corporation) and measured. This allows the average particle size D90 to be obtained by the laser diffraction / scattering method. The average particle size D90 is the particle size at the 90% stage of the cumulative average particle size. It is used to define the size of larger particles in the particle size distribution.

[0011] The cochineal dye surface-treated with the hydrophobic treatment agent of the present invention is described below. (Cochineal dye) The cochineal dye of this invention is a red pigment used as a dye or food additive (natural coloring agent). It is derived from the dried bodies of female insects of the superfamily Coccoidea, particularly Asian lac insects, Southern European kermes insects, and Mexican cochineal insects. The pigment compounds accumulated within these insects are extracted with water or ethanol. Its essence is carminic acid, an anthraquinone derivative, and it is also called carminic acid dye. It can also be used in a form laked with calcium or aluminum. A dye containing carminic acid or its lake is preferred. These dyes are preferred because they impart a bluish-red hue, have a desirable color, and are suitable for complying with regulations in countries where tar dyes cannot be used, or for addressing color requirements for restricted items. Commercially available cochineal dyes include Carmine NF (manufactured by Taketombo Co., Ltd.) and UNIPURE RED LC320 (manufactured by Sensient Co., Ltd.).

[0012] (Hydrophobic treatment agent) The hydrophobic treatment agent used in the present invention exhibits hydrophobicity when cochineal dye is surface-treated. Hydrophobicity is defined as the property of having a contact angle of 90° or more with water after 1 second when water is dropped onto the surface of a pressure-molded product of cochineal dye that has been surface-treated at 25°C. This range is preferable because it increases the water resistance of the cochineal dye and improves its fade stability. The hydrophobic treatment agent may be made from raw materials of any origin, such as animal, plant, or synthetic origin, and can be used regardless of its properties, such as solid, semi-solid, or liquid. It may also be a reactive hydrophobic treatment agent such as silane treatment, titanate treatment agent, or methylhydrogen treatment, or an oily agent such as hydrocarbons, oils and fats, hydrogenated oils, ester oils, silicone oils, fluorinated oils, or lanolin derivatives, or fatty acids, higher alcohols, or oily gelling agents. In particular, it is preferable to have a dimethylpolysiloxane structure and one or more alkyl groups selected from those having C12 to C30 carbon atoms. Furthermore, among these, structures having one or more selected from carboxyl groups and hydroxyl groups are particularly preferred. Such structures are preferable because they readily adsorb to cochineal dye, enhance the decomposition effect, reduce the cohesive force of cochineal dye, prevent re-aggregation when incorporated into cosmetics through surface treatment, improve the water resistance of the dye and enhance fade stability, and provide excellent smoothness when applied, uniformity of color, and good color development when incorporated into cosmetics. Moreover, among alkyl groups, C16-30 alkyl groups are even more preferable from the viewpoint of cosmetic longevity. There are no particular limitations on structures containing phosphorus, nitrogen, or sulfur sources. However, structures containing a carbon source but not phosphorus, nitrogen, or sulfur sources are even more preferable, as this structure is even more preferable from the viewpoint of preservatives as it is easily incorporated into cosmetics. One or more types can be used in combination as needed.

[0013] The hydrophobic treatment agents used in the present invention include, specifically, reactive hydrophobic treatment agents such as triethoxycaprylylsilane and titanate triisostearate. Furthermore, as oils, the following are used: hydrocarbon oils such as liquid paraffin, squalane, squalene, polyisobutylene, polybutene, and petrolatum; fatty acids or their metal soaps such as lauric acid, isostearic acid, stearic acid, 12-hydroxystearic acid, and oleic acid; liquid higher alcohols such as hexyldecanol, isostearyl alcohol, stearyl alcohol, oleyl alcohol, octyldodecanol, and decyltetradecanol; glyceryl tri-2-ethylhexanoate, caprylic / capric triglyceride, glyceryl diisostearate, glyceryl triisostearate, diglyceryl triisostearate, diglyceryl diisostearate, diglyceryl tetraisostearate, polyglyceryl decaisostearate, propylene glycol dicaprate, isotridecyl isononanoate, pentaerythritol tetra-2-ethylhexanoate, tetra Examples include ester oils such as pentaerythritol lyisostearate, trimethylolpropane triisostearate, cetyl 2-ethylhexanoate, isopropyl myristate, isopropyl palmitate, octyldodecyl myristate, isocetyl stearate, octyldodecyl oleate, neopentyl glycol dioctanoate, di-2-ethylhexyl succinate, diisostearyl malate, myristyl lactate, dialkyl carbonate, liquid lanolin acetate, tridecyl trimellitate, and diisopropyl dimerate; animal fats and oils such as beeswax; vegetable oils and oils such as avocado oil; and silicone oils such as dimethiconol, methylhydrogenpolysiloxane, phenylmethicone, phenyl dimethicone, phenyl trimethicone, diphenyl dimethicone, diphenylsiloxy phenyl trimethicone, triphenyl trimethicone, and trimethylpentaphenyltrisiloxane.

[0014] Furthermore, the hydrophobic treatment agent used in the present invention is preferably a liquid hydrophobic treatment agent at 25°C, and is preferably one that has a hydroxyl group rather than one that changes the structure by reaction to treat the surface. For example, one or more selected from liquid higher alcohols at room temperature of 25°C, liquid fatty acids or their salts at room temperature of 25°C, and silicone oils having a hydroxyl group are more preferable. Specifically, it is even more preferable to use decyltetradecanol, octyldodecanol, isostearyl alcohol as liquid higher alcohols at room temperature of 25°C, isostearic acid as a liquid fatty acid or its salt at room temperature of 25°C, and dimethiconol as a silicone oil having a hydroxyl group. Among these, decyltetradecanol and octyldodecanol are particularly preferred. Commercially available products include Risonol 20SP (octyldodecanol) and Risonol 24SP (decyltetradecanol (manufactured by Higher Alcohol Industry Co., Ltd.)).

[0015] The amount of surface treatment with a hydrophobic agent on surface-treated cochineal dye is not particularly limited, but the lower limit is preferably 1% or more, more preferably 1.5% or more, and still preferably 2% or more. The upper limit is preferably 20% or less, more preferably 8% or less, and still preferably 6.5% or less. This range is preferable because it provides excellent smoothness when applying the surface-treated cochineal dye, uniformity of color, good color development when included in cosmetics, and the absence of aggregates. There are no particular limitations on the evaluation method for the hydrophobicity of surface-treated cochineal dye, but for example, it can be evaluated by the following method: Fill a metal dish (4 cm long, 4 cm wide, 0.4 cm thick) with 10 g of sample bulk and press it under a pressure of 200 kg / cm². 2 The sample is prepared for measurement by pressure molding using the force of the machine. The measurement is performed using a contact angle measuring device (Dropmaster DM500, manufactured by Kyowa Interface Science Co., Ltd.) and the droplet method (θ / 2 method). 1.0 μL of purified water is dropped onto the press surface, and the contact angle is measured after 1.0 second. Each measurement is performed three times, and the average value is taken as the contact angle with water.

[0016] (Method for Producing Surface-Treated Cochineal Dye) In the present invention, for the surface treatment method of cochineal dye, known treatment methods that have conventionally been used for modifying powders used in cosmetics can be utilized. For example, a wet method using a solvent, a dry method for treatment in the gas phase, etc. can be used. Particularly, after mixing with a volatile solvent, it is preferable to dry and pulverize into fine powder. As specific volatile solvents, in particular, when treating by a wet method using an alcohol solvent such as isopropyl alcohol or a hydrocarbon solvent such as hexane or isododecane, the surface treatment becomes uniform, which is preferable for the color stability and dispersibility of cochineal dye that is weak to water. Specifically, when using a hydrophobizing agent and a volatile solvent, the hydrophobizing agent is dissolved in the solvent, the cochineal dye is added to the solution, and after uniformly stirring and mixing with a mixer such as a Henschel mixer, kneader, ultra mixer, bead mill, etc. to disperse or moisten, when containing a solvent, the solvent is recovered or evaporated and dried to be homogenized, and then pulverized to obtain a surface-treated cochineal dye, but it is not particularly limited as long as the surface treatment can be uniformly performed on the dye surface. Furthermore, examples of the pulverization method include devices such as a jet mill, atomizer, parubelizer, grinder, etc. for crushing ordinary granulated powders. The method is not particularly limited. Furthermore, the cochineal dye of the present invention is pulverized until the average particle diameter D90 is 500 μm or less as the upper limit. It is more preferable that it is less than 200 μm, further more preferable that it is less than 100 μm, even more preferable that it is less than 50 μm, and within this range, it becomes difficult to visually confirm aggregates, and it is particularly preferable that it is less than 10 μm. As the lower limit, there is no particular limitation, but it is preferably 0.05 μm or more, and more preferably 0.1 μm or more. At this size, when contained in a cosmetic, it is likely to be a size where it is difficult to visually confirm particles, which is preferable in terms of improving the absence of aggregates in the cosmetic and enhancing the color development. [[ID=⑤]] [[ID=⑥]]

[0017] [[ID=⑦]] [[ID=⑧]](Cosmetic)[[ID=⑨]] The cosmetic of the present invention is produced by containing one or more of the above surface-treated powders in combination with known cosmetic ingredients according to a conventional method. The content of the surface-treated cochineal pigment in the cosmetic of the present invention is not particularly limited and varies depending on the dosage form and item of the cosmetic. However, the lower limit is preferably 0.5% or more, more preferably 1.0% or more, still more preferably 1.5% or more, and even more preferably 2% or more. The upper limit is preferably 20% or less, more preferably 15% or less, and still more preferably 10% or less. This range is preferable because it is excellent in color development and lack of aggregates when contained in a cosmetic.

[0018] The cosmetic of the present invention can appropriately contain components that can be contained as necessary. For example, oils, surfactants, alcohols, water, moisturizers, gelling agents and thickeners, powders other than the above surface-coated treated powders, ultraviolet absorbers, preservatives, antibacterial agents, antioxidants, beauty ingredients (whitening agents, cell activators, anti-inflammatory agents, blood circulation promoters, skin astringents, anti-seborrheic agents, etc.), vitamins, amino acids, nucleic acids, hormones, etc. can be contained.

[0019] Examples of the dosage form of the cosmetic of the present invention include powder dosage form, oil-in-water emulsion dosage form, water-in-oil emulsion dosage form, oily dosage form, aqueous dosage form, solvent dosage form, etc. Examples of the form of the cosmetic include powdery, powder solid, oily solid, creamy, gelled, liquid, mousse, spray, etc. The cosmetic of the present invention only needs to contain the surface-treated powder of the present invention. In particular, it can be suitably used for makeup cosmetics such as foundation, concealer, face powder, eyeshadow, blush, makeup base, eyeliner, lipstick, eyebrow, mascara, eyeliner, nail polish, etc., and sunscreen cosmetics. Among these, as the dosage form, a powder dosage form or an oily dosage form is preferable, and the effect is easily exhibited in a dosage form with less fluidity and easy to observe dispersibility on the surface. Also, as the form of the makeup cosmetic, a powder solid or an oily solid is preferable, and it is preferably used for eyeshadow, cheek, etc. as the makeup cosmetic.

[0024] (Evaluation criteria) I. Contact angle (hydrophobicity evaluation) (b) Absence of aggregates of pigment particles

[0025] (Evaluation Method 1) I. Contact angle (hydrophobicity evaluation) Manufacturing Examples 1-16 and Manufacturing Comparative Examples 1-4, prepared using the above preparation method, were filled at a rate of 10g each into a metal tray (4cm long, 4cm wide, 0.4cm thick) and pressed under a pressure of 200kg / cm². 2 The sample was prepared for measurement by pressure molding using the force of the machine. The measurement was performed using a contact angle measuring device (Dropmaster DM500, manufactured by Kyowa Interface Science Co., Ltd.) and the droplet method (θ / 2 method). 1.0 μL of purified water was dropped onto the press surface, and the contact angle was measured after 1.0 second. Each measurement was performed three times, and the average value was taken as the contact angle with water.

[0026] (Evaluation Method 2) (b) Absence of aggregates of pigment particles To measure the size of the sample (powder) in the gas phase, it was forcibly dispersed using compressed air in a dry measurement unit and then placed into the sample input port of a laser diffraction / scattering particle size distribution analyzer (Laser diffraction / scattering particle size distribution analyzer (particle size distribution) LA-960V2, HORIBA Corporation) for measurement. This allowed for the measurement of the average particle size D90 using the laser diffraction / scattering method, and the average particle size of the larger regions was determined.

[0027] (Judgment): (Average score) AA: Average particle size D90 is less than ~50μm A: Average particle size D90 is 50 μm or more and less than 200 μm. B: Average particle size D90 is 200-600 μm C: Average particle size D90 exceeds 600 μm

[0028] As is clear from the results shown in Table 1, the cochineal dyes described in Manufacturing Examples 1 to 16 were good in terms of contact angle (hydrophobicity evaluation) and the absence of pigment particle aggregation. On the other hand, untreated Manufacturing Comparative Example 1 was unsatisfactory in all respects, including contact angle (hydrophobicity evaluation) and the absence of pigment particle aggregation. Furthermore, Manufacturing Comparative Example 2 using highly hydrophilic 1,3-butylene glycol, Manufacturing Comparative Example 3 using dipropylene glycol, and Manufacturing Comparative Example 4 using polysorbate-80 were also unsatisfactory in terms of contact angle (hydrophobicity evaluation) and the absence of pigment particle aggregation.

[0029] (Example of cosmetic formulation) The surface-treated powders prepared by the above method in Manufacturing Examples 1-5, 7, 9, 10, 12, 13, 15 and Manufacturing Comparative Examples 1-4 were used in the following cosmetic formulations. Examples 1-15 and Comparative Examples 1-5: Eyeshadow Eyeshadows for Examples 1-15 and Comparative Examples 1-5 were prepared using cochineal dye obtained by the manufacturing method shown in Table 1. Each of the obtained eyeshadows was evaluated for the following reasons: c. smoothness during application, d. uniformity of color, e. good color development, and f. absence of aggregates. These results are also shown in Table 2.

[0030] [Table 2]

[0031] (Manufacturing method): Examples 1-15 and Comparative Examples 1-5: Eyeshadow A. Mix ingredients (1) to (20) uniformly. B. Heat components (21) to (25) to 60°C and mix uniformly. Add B to CA to make a cosmetic base, add about 50 parts by mass of isododecane to 100 parts by mass of the cosmetic base and mix and knead, then fill 2.5 g of the mixture into a metal dish container (2.5 cm × 2 cm × 0.3 cm thick). Two sheets of 0.02 mm thick cellulose paper were placed on the surface of the DC, and then a mold was used to press it down, at a rate of 2 kgf / cm². 2 After compressing and molding the product, isododecane was removed by suction for 4 seconds, and then the product was dried at 70°C for 8 hours to obtain a solid eyeshadow.

[0032] (Methods for evaluating cosmetics) (Evaluation criteria) H. Smoothness during application II. Uniformity of the applied color H. Good color payoff Absence of aggregates The following methods were used to evaluate this.

[0033] H. Evaluation method for smoothness during application, and II. Evaluation method for uniformity of applied color. For items C and D, each sample was subjected to a usage test by a panel of 20 cosmetic product experts. Each panelist used the cochineal dyes from Examples 1-15 and Comparative Examples 1-5, and evaluated them on a 7-point scale according to the absolute evaluation criteria below, assigning a score. The average score was calculated from the total scores of all panelists for each sample, and the evaluation was made according to the following criteria. C. For smoothness during application, each sample was applied to the skin and evaluated whether it spread smoothly without feeling rough on the skin during application. D. For uniformity of color, it was evaluated whether the color applied to the skin was uniform without unevenness.

[0034] Absolute evaluation criteria (Rating): (Evaluation) 6: Very good 5: Good 4: Fairly good 3: Normal 2: Slightly bad 1: Bad 0: Very bad (Judgment): (Average score) ◎: 5 points or more ○: 3.5 points or higher, but less than 5 points △: 2 points or more, but less than 3.5 points ×: Less than 2 points

[0035] H. Method for evaluating color development For the eyeshadows of Examples 1-15 and Comparative Examples 1-5, a user test was conducted by a panel of 20 experts to determine whether sufficient color development was achieved when applied to the skin. The eyeshadows were evaluated on a 7-point scale using the absolute evaluation criteria below, and scores were assigned. For each sample, the average score was calculated from the sum of the scores from all panel members, and the evaluation was made according to the judgment criteria below.

[0036] Absolute evaluation criteria (Rating): (Evaluation) 6: Very good 5: Good 4: Fairly good 3: Normal 2: Slightly bad 1: Bad 0: Very bad

[0037] (Judgment): (Average score) ◎: 5 points or more ○: 3.5 points or higher, but less than 5 points △: 2 points or more, but less than 3.5 points ×: Less than 2 points

[0038] e. Method for evaluating the absence of aggregates For the eyeshadows of Examples 1-15 and Comparative Examples 1-5, the surface of five samples filled in a gold dish container (2.5cm x 2cm x 0.3cm thick) was rubbed 20 times with a brush, and the aggregates of cochineal dye scattered on the sample surface and around the sample were visually observed and the average was calculated. Aggregates that could be visually observed were defined as those in which streaks of color could be felt when the surface was touched with a finger after rubbing. (Judgment criteria) (Judgment): (Average score) ◎: No powder aggregates ○: One aggregate of powder △: Two to three clumps of powder ×: Four or more aggregates of powder

[0039] As is clear from the results shown in Table 2, the eyeshadows of Examples 1 to 15 were good in terms of smoothness during application, uniformity of color, good color development, and absence of aggregates. On the other hand, Comparative Example 1, which was untreated, was not satisfactory in terms of smoothness during application, good color development, and absence of aggregates. Comparative Examples 2 and 3, which underwent a highly hydrophilic surface treatment, also showed reduced dispersibility in the cosmetic oil and were not satisfactory in terms of good color development and absence of aggregates. In Comparative Example 4, the good color development was satisfactory, but the cochineal dye aggregated in the cosmetic. In Comparative Example 5, which was untreated, when the cochineal dye and other powder mixture was mixed with an oil and a hydrophobic treatment agent was added, the hydrophobic treatment agent did not selectively act on the dye, and therefore was not satisfactory in terms of smoothness during application and good color development.
