Description

[Technical Field]

[0001] The present invention relates to a hair cosmetic composition and a hair cosmetic containing the hair cosmetic composition, and in particular to a hair cosmetic composition having excellent color retention and a hair cosmetic containing the hair cosmetic composition. [Background technology]

[0002] Hair coloring mainly includes hair colors, which are permanent hair dyes that are quasi-drugs, and semi-permanent hair dyes that are cosmetics, such as hair manicures and hair color treatments. In particular, most permanent hair dyes contain a substance called paraphenylenediamine (oxidation dye), but when it comes to dark black colors, the amount of diamine compounds mixed in is high, so even more care is required.

[0003] For example, a hair coloring composition containing paraphenylenediamine (oxidation dye) is known, which is characterized by comprising (a) a water-soluble peroxygen bleach; (b) a bleaching aid selected from organic peroxyacid bleach precursors and / or preformed organic peroxyacids; and (c) one or more hair coloring agents (Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Special table Hei 11-501947 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0005] However, in the prior art, including Patent Document 1, products containing paraphenylenediamine (oxidation dye) require even more care when using dark black colors, as described above, because the amount of diamine-based compound is greater. In addition, in recent years, skin disorders caused by a substance called paraphenylenediamine (oxidation dye) have been reported.

[0006] In addition, hair manicure, a semi-permanent hair dye, is characterized by the fact that the pigment (acid dye) penetrates deep into the hair after just one use, and the color lasts for 2 to 3 weeks. However, the longer it is left on the scalp, the harder it becomes to remove the dyed pigment. It is difficult for the person applying it to apply it right up to the hairline, and the dyeing is poorer than hair color, considering the skill of the person applying it, so it is a hair dye that is often avoided at salons and beauty parlors.

[0007] On the other hand, while the above-mentioned hair colors can dye the cortex (the inner part of the hair) thoroughly, hair color treatments only dye the cuticle (hair cuticle) and the cortex near the surface of the hair, and in some cases, they cannot achieve a hair color that lasts long enough.

[0008] Therefore, an object of the present invention is to provide a hair cosmetic composition and a hair cosmetic that have better color retention when dyeing hair. [Means for solving the problem]

[0009] In order to achieve the above object, the present inventors have conducted extensive research into treatments before and after hair color treatment, and as a result have come up with the present invention.

[0010] That is, the present invention Color treatment method teeth, applying a hair color agent containing a basic dye, a thickener, and a preservative; A hair cosmetic composition comprising an amphoteric surfactant containing sodium cocoamphoacetate, a nonionic surfactant, an alkaline agent, and a pH adjuster. (However, anionic surfactants are excluded.) The hair cosmetic composition, wherein the pH adjuster is at least one selected from phosphoric acid, glyoxylic acid, lactic acid, phytic acid, citric acid, malic acid, succinic acid, glutamic acid, aspartic acid, and tartaric acid, and the alkaline agent is at least one selected from tetrahydroxypropylethylenediamine, sodium hydroxide, potassium hydroxide, and aqueous ammonia. and applying a hair cosmetic composition, wherein the amount of the amphoteric surfactant is 1 to 20% by mass, the amount of the nonionic surfactant is 3 to 15% by mass, the amount of the alkaline agent is 0.01 to 5% by mass, and the amount of the pH adjuster is 0.01 to 3% by mass, based on the total amount of the composition. It is characterized by:

[0014] In a preferred embodiment of the hair cosmetic composition of the present invention, the pH adjuster is selected from the group consisting of phosphoric acid, glyoxylic acid, lactic acid, phytic acid, citric acid, malic acid, succinic acid, glutamic acid, or aspartic acid It is characterized in that it is at least one selected from the following. [Effects of the Invention]

[0019] The hair cosmetic composition of the present invention has the advantageous effect of being able to provide a hair color product that can be used safely, has long-lasting color, and can be applied to new hair growth without worrying about the product adhering to the scalp, as it is likely that the use period of hair color will be extended due to aging. DETAILED DESCRIPTION OF THE INVENTION

[0020] The hair cosmetic composition of the present invention is characterized by containing an amphoteric surfactant, a nonionic surfactant, an alkaline agent, and a pH adjuster. The pH of healthy hair is approximately 4.5 to 5.5, and the ionicity of hair is generally maintained in equilibrium. In the present invention, by using an amphoteric surfactant and a nonionic surfactant in combination, applying a hair colorant and then applying the hair cosmetic composition of the present invention can improve the color retention of the hair colorant.

[0021] The pH value of the hair cosmetic composition of the present invention can be adjusted to preferably 5.0 to 6.5, more preferably 5.5 to 6.0, from the viewpoint of dye color retention and hair color tone.

[0022] In a preferred embodiment of the hair cosmetic composition of the present invention, the amphoteric surfactant is, but is not limited to, at least one selected from the group consisting of sodium cocoamphoacetate, sodium lauraminopropionate, cocamidopropyl betaine, lauramidopropyl betaine, and lauryl hydroxysultaine, from the viewpoint of foaming and cleansing power. The amount of the amphoteric surfactant is, but is not limited to, preferably 1 to 20% by mass, more preferably 3 to 15% by mass, based on the total amount of the composition, from the viewpoint of smoothness after rinsing and drying.

[0023] In a preferred embodiment of the hair cosmetic composition of the present invention, the nonionic surfactant is at least one selected from decyl glucoside, caprylyl / capryl glucoside, coconut oil alkyl glucoside, lauryl glucoside, and polyglyceryl-10 laurate from the viewpoint of foaming. The amount of the nonionic surfactant is not particularly limited, but from the viewpoint of cleansing power, it is preferably 1 to 20% by mass, more preferably 3 to 15% by mass, of the total amount of the composition.

[0024] In a preferred embodiment of the hair cosmetic composition of the present invention, the alkaline agent is at least one selected from tetrahydroxypropylethylenediamine, triethanolamine, sodium hydroxide, potassium hydroxide, and aqueous ammonia, from the viewpoint of maintaining hair color tone over time. The amount of the alkaline agent is not particularly limited, but from the viewpoint of preventing irritation, it is preferably 0.01 to 5 mass%, more preferably 0.1 to 3 mass%, of the total amount of the composition.

[0025] In a preferred embodiment of the hair cosmetic composition of the present invention, the pH adjuster is at least one selected from phosphoric acid, glyoxylic acid, lactic acid, phytic acid, citric acid, malic acid, succinic acid, glutamic acid, aspartic acid, and tartaric acid, from the viewpoint of dye color retention. The amount of the pH adjuster is not particularly limited, but from the viewpoint of hair color tone over time, it is preferably 0.01 to 3 mass %, more preferably 0.1 to 2 mass %, based on the total amount of the composition.

[0026] In a preferred embodiment of the hair cosmetic composition of the present invention, the composition further contains at least one modifier selected from sodium chloride, glycine, sorbitol, hydrolyzed collagen, potassium chloride, edetic acids, and etidronic acids, from the viewpoint of preventing discoloration. The amount of the modifier is not particularly limited, but from the viewpoint of preventing discoloration, it is preferably 0.1 to 30% by mass, more preferably 1 to 20% by mass, based on the total amount of the composition.

[0027] In a preferred embodiment of the hair cosmetic composition of the present invention, the hair cosmetic composition is intended for application to hair after treatment with a basic dye. Specifically, the amphoteric surfactant and nonionic surfactant contained in the hair cosmetic composition improve the color retention of the hair colorant, i.e., the basic dye. As described above, the pH of healthy hair is approximately 4.5 to 5.5, and the ionic nature of hair is generally balanced. However, when the pH of a hair cosmetic composition is near neutral, the amphoteric surfactant is amphoteric and anionic, resulting in the presence of many negative ions in the hair cosmetic composition, which compete with the positive ions of the basic dye. Because basic dyes are positively charged, if an anionic surfactant is included, the hydrophilic group of the anionic surfactant may exhibit negative ionicity and remove the dye. In contrast, the amphoteric surfactant used in the present invention has both positive and negative properties, but exhibits cationic properties in the acidic range and anionic properties in the alkaline range. Furthermore, nonionic surfactants do not affect dyes in the first place. For these reasons, the present inventors have discovered that, particularly when dyes, particularly basic dyes, are used, the use of amphoteric surfactants and nonionic surfactants contained in the hair cosmetic composition can improve the color retention of the dye.

[0028] The hair cosmetic of the present invention is characterized by containing the hair cosmetic composition of the present invention.

[0029] The color treatment method of the present invention is characterized by comprising the steps of applying a hair color agent containing a basic dye, a thickener, and a preservative, and applying the hair cosmetic composition of the present invention. In the present invention, the basic dye is not particularly limited, but examples thereof include Basic Brown 16, Basic Blue 99, Basic Red 51, and Basic Yellow 87, from the viewpoint of dyeing ability. The amount of the basic dye is not particularly limited, but from the viewpoint of hair damage, it is preferably 0.0005 to 5% by mass, more preferably 0.1 to 1% by mass, based on the total amount of the composition.

[0030] In the present invention, the thickener is not particularly limited, but examples thereof include PEG-150 pentaerythrityl tetrastearate, cocamide methyl MEA, cocamide DEA, etc., from the viewpoint of enhancing foaming and thickening. The amount of the basic dye is not particularly limited, but from the viewpoint of foam stability, it is preferably 0.1 to 10% by mass, more preferably 0.3 to 7% by mass, relative to the total amount of the composition.

[0031] In the present invention, the preservative is not particularly limited, but from the viewpoint of the burden on the scalp, examples thereof include sodium benzoate, methylparaben, phenoxyethanol, etc. The amount of the basic dye is not particularly limited, but from the viewpoint of the stability of the product, it is preferably 0.01 to 1% by mass, more preferably 0.1 to 0.8% by mass, relative to the total amount of the composition.

[0032] For the hair cosmetic composition, the above description of the hair cosmetic composition of the present invention can be referred to. [Example]

[0033] An example of the present invention will be described below, but the present invention should not be construed as being limited to the following example.

[0034] Example 1 First, a test hair bundle sample 1) was prepared. The procedure for preparing a hair bundle dyed with a basic dye is as follows. A hair bundle made of 100% human white hair (1 g x 1 cm) (product number: BM-WA, manufactured by Beaulux) was coated with the hair dye (hair colorant) of formula 1 and wrapped. The hair was then left at 40°C for 30 minutes in a constant temperature dryer (model: SDN27P, manufactured by Sansho Co., Ltd.), after which the hair cosmetic composition of the present invention was applied (washed), and the hair was dried to prepare test hair bundle sample 1). The details of formula 1 are shown in Table 1. In the hair dye of formula 1, hydroxyethyl cellulose was used as a thickener, and methylparaben was used as a preservative. The pH of the hair dye was adjusted to 6.8 or higher.

[0035] [Table 1]

[0036] Table 2 shows the ingredients of the applied hair cosmetic composition of the present invention.

[0037] [Table 2]

[0038] In Table 2, the sources of A), D), F), and H) are as follows: A) Softazoline CL-R (Kawaken Fine Chemicals Co., Ltd.), D) Plantacare 2000 UP (BASF Japan Ltd.), F) Adeka Carpol MD-100 (ADEKA Corporation), and H) Nippipeptide CQT-F01-G (Nippi Corporation).

[0039] The hair cosmetic composition of the present invention in one example was a pale yellow to yellowish brown liquid, had a pH of about 5.8, and a viscosity of 2,300 mPa·s. In the present invention, no anionic surfactant was used, and sodium cocoamphoacetate was used as the amphoteric surfactant, and decyl glucoside was used as the nonionic surfactant.

[0040] Next, the color retention of the hair colorant, i.e., the effect of inhibiting fading, was investigated using the hair cosmetic composition of the present invention. Specifically, the test hair bundle sample 1) prepared as described above was measured using a spectrophotometer (model: SD6000, manufactured by Nippon Denshoku Industries Co., Ltd.). The results are shown in Table 3.

[0041] [Table 3]

[0042] Example 2 Next, a comparison was made between the use of an anionic surfactant and a nonionic surfactant using the test hair bundle sample 1) of Example 1. For Example 2 and Comparative Examples 1 and 2, the hair cosmetic compositions were adjusted to around pH 5.0, and the dyed test hair bundle sample 1) was placed in each test tube. Hair cosmetic composition applicable to the method of the present invention 25 g of each of the hair cosmetic compositions of Comparative Examples 1 and 2 was poured into the hair, and the hair was left at 25°C for 24 hours using a programmable low-temperature incubator (model IN804, Yamato Scientific Co., Ltd.), then rinsed and dried, and the color was measured using a spectrophotometer (model SD6000, Nippon Denshoku Industries Co., Ltd.). Comparative Example 1 is an example of a combination of an anionic (anionic) surfactant and an amphoteric surfactant, in which sodium laureth sulfate, a polyoxyethylene alkyl ether sulfate salt widely used as an anionic (anionic) surfactant, was used. Comparative Example 2 is an example of a combination of an anionic (anionic) surfactant and an amphoteric surfactant, in which TEA-cocoyl glutamate, widely used as an amino acid surfactant for anionic (anionic) surfactants, was used. Example 2 is an example of a combination of a nonionic (nonionic) surfactant and an amphoteric surfactant, in which decyl glucoside, an alkyl polyglucoside type with excellent foaming properties, was used as the nonionic (nonionic) surfactant. Table 4 shows the components and amounts used in each of Example 2 and Comparative Examples 1 and 2.

[0044] In Table 4, the sources of A) to E) are as follows: A) Softazoline CL-R (Kawaken Fine Chemicals Co., Ltd.), B) Emal 327 (Kao Corporation), C) Amisoft CT-12S (Ajinomoto Co., Inc.), D) Plantacare 2000 UP (BASF Japan Ltd.), and E) Catinal HC-200 (Toho Chemical Industry Co., Ltd.).

[0045] Similarly, the test hair bundle samples 1) used in Example 2 and Comparative Examples 1 and 2 were subjected to color measurement using a spectrophotometer (model: SD6000, manufactured by Nippon Denshoku Industries Co., Ltd.). The results are shown in Table 5.

[0046] [Table 5]

[0047] As a result, it was found that Example 2, which used a combination of a nonionic surfactant and an amphoteric surfactant, had a small color difference of 17.29, and was excellent in color retention, that is, in the effect of inhibiting discoloration.

[0048] Example 3 Next, a dye containing a nonionic surfactant was prepared to prepare test hair bundle sample 2). A hair bundle of 100% human white hair (1 g x 1 cm) (product number: BM-WA, manufactured by Beaulax) was placed in a test tube, and 25 g of the hair dye of formulation 2 was dispensed into it. The hair bundle was then left to stand at 25°C for 20 minutes using a programmable low-temperature incubator (model: IN804, manufactured by Yamato Scientific Co., Ltd.), after which it was washed with the hair cosmetic composition of the present invention and dried to prepare test hair bundle sample 2). Prescription 2 The contents are shown in Table 6.

[0050] The source of D) in Table 6 is as follows: D) Plantacare 2000 UP (manufactured by BASF Japan Ltd.).

[0051] Examples 4 to 12 Next, inorganic and organic acids applicable as pH adjusters were widely investigated. That is, the color retention was examined by examining the composition containing each of the components of Examples 4 to 12 to see if there was any change in color retention depending on the inorganic and organic acids added. Applicable to the method of the present invention The hair cosmetic composition was adjusted to approximately pH 4.5 and left at 40°C for 60 minutes using a constant temperature dryer (model: SDN27P, Sansho Co., Ltd.). While the composition was left standing, the test hair bundle sample 2) prepared as described above was placed into a test tube. After leaving the composition, 25 g of the sample was dispensed into each test tube and left at 40°C for 30 minutes. After rinsing and drying, color retention was compared visually. It was found that phytic acid, glutamic acid, and aspartic acid also had good color retention. Furthermore, phytic acid was the organic acid with the best color retention. The results are shown in Table 7. In comparison with the results of Example 3, this demonstrates that the hair cosmetic composition of the present invention may be applied in addition to a hair dye containing a basic dye and a nonionic surfactant. Furthermore, it was found that excellent color retention was achieved even when an inorganic or organic acid was applied after applying the hair cosmetic composition of the present invention.

[0053] In Table 7, F) was obtained from the following source: F) ADEKA Carpol MD-100 (manufactured by ADEKA Corporation).

[0054] Examples 13 to 15 As the results of Examples 4 to 12 showed that phytic acid was superior, we next investigated the relationship between the blending amount and pH of phytic acid and color retention. Using the test hair bundle sample 2) prepared as described above, we tested a hair bundle containing the components of Examples 13 to 15. Applicable to the method of the present inventionTo confirm the color difference due to the amount of phytic acid in the hair cosmetic composition and pH, the composition was left at 40°C for 60 minutes in a constant temperature dryer (model: SDN27P, Sansho Co., Ltd.). While the composition was left, test hair bundle sample 2) was placed in a test tube, and after leaving it, 25 g of the sample was dispensed into each test tube and left at 40°C for 30 minutes. After rinsing and drying, the color was measured using a spectrophotometer (model: SD6000, Nippon Denshoku Industries Co., Ltd.). At a similar pH, i.e., around pH 3, the greater the amount of phytic acid, the smaller the color difference. When the phytic acid (50% solution) was around 2.80%, the lower the pH, the smaller the color difference. The results are shown in Table 8.

[0055] [Table 8] The source of F) in Table 8 is F): ADEKA Carpol MD-100 (manufactured by ADEKA Corporation).

[0056] Examples 16 to 20 Next, we investigated whether there was a difference in color retention depending on the modifier. Test hair bundle sample 1) prepared in the above-mentioned example was used as the test hair bundle sample. As a result, among the test hair bundle samples 1) dyed with basic dyes, the one containing sodium chloride had the smallest color difference. The ingredients and amounts of the compounds in Examples 16 to 20 are shown in Table 9.

[0059] Similarly to the above-mentioned examples, the test hair bundle sample 1) was measured for color using a spectrophotometer (model: SD6000, manufactured by Nippon Denshoku Industries Co., Ltd.), and the results are shown in Table 10.

[0060] [Table 10]

[0061] As described above, it has been found that the present invention provides a hair cosmetic composition and a hair cosmetic that have excellent color retention when applied to hair that has been treated with a hair dye, particularly a basic dye. [Industrial Applicability]

[0062] According to the present invention, it is possible to improve color retention in hair color treatments, and the present invention is highly useful in a wide range of industries.
