Description

Technical Field

[0001] The present invention relates to a composition for suppressing fading of dyed hair under high humidity conditions and a method for suppressing fading of dyed hair under high humidity conditions using the same.

Background Art

[0002] Hair dyeing has been practiced for a long time. In recent years, with the improvement of the performance of hair dyes, it has become possible to dye hair in various colors, and thus it has become established as a part of fashion. Hair dyeing includes, in addition to white hair dyeing and hair coloring using oxidative hair dyes as hair dyes, hair manicure using acid hair dyes, etc. However, it is known that hair fades due to factors such as hair washing and ultraviolet rays, and dye fastness by shampoo fastness test and sunlight fastness test is used as an index for evaluating the persistence of the dyeing effect by hair dyes.

[0003] For the purpose of preventing fading of dyed hair due to such hair washing and ultraviolet rays, various techniques have been studied. For example, a post-treatment agent composition for hair dyeing containing an ester compound of an unsaturated dicarboxylic acid having 4 to 6 carbon atoms and an alcohol having 12 to 24 carbon atoms (Patent Document 1), a hair cosmetic containing chitosans, sterols and oxycarboxylic acids (Patent Document 2), an oily hair cosmetic composition containing isoparaffins having a flash point of 70°C or higher and less than 150°C, ester oils or vegetable oils, and isoparaffins having a flash point of 40°C or higher and less than 70°C (Patent Document 3), etc. have been disclosed.

[0004] On the other hand, the present inventors have obtained the knowledge that fading of dyed hair progresses not only due to hair washing and ultraviolet rays but also under high humidity conditions, but no technique has been reported so far for the purpose of preventing fading of dyed hair caused by such humidity.

[0006] An object of the present invention is to provide a composition capable of suppressing fading of dyed hair under high humidity conditions. [Means for Solving the Problems]

[0007] As a result of intensive studies to solve the above problems, the present inventors have found that when one or more hair protecting components selected from cationic surfactants and water-soluble film-forming resins are applied to dyed hair, fading of the hair under high humidity conditions is suppressed, and the present invention has been completed.

[0008] That is, the present invention is a composition for suppressing fading of dyed hair under high humidity conditions, containing, as an active ingredient, one or more hair protecting components selected from cationic surfactants and water-soluble film-forming resins.

[0009] Further, the present invention is a method for suppressing fading of dyed hair under high humidity conditions, in which one or more hair protecting components selected from cationic surfactants and water-soluble film-forming resins are applied to dyed hair. [Effects of the Invention]

[0010] By applying the composition of the present invention to dyed hair, the suppressing effect on fading that progresses under high humidity conditions is high, and the color of the hair after dyeing can be maintained for a long period of time. [Brief Description of the Drawings]

Mode for Carrying Out the Invention

[0012] The composition for suppressing fading of dyed hair under high humidity conditions of the present invention (hereinafter referred to as "the composition of the present invention") contains, as an active ingredient, one or more hair protecting components selected from cationic surfactants and water-soluble film-forming resins.

[0013] The active ingredient of the present invention is one or more hair protecting components selected from cationic surfactants and water-soluble film-forming resins.

[0014] The "hair protecting component" in the present invention is a component that protects (coats) the hair surface by adsorbing to the hair. Although it is not clear why one or more hair protecting components selected from cationic surfactants and water-soluble film-forming resins can suppress fading of dyed hair under high humidity conditions, among the hair protecting components, it is considered that the progress of fading under high humidity conditions is suppressed by protecting the hair surface with a cationic surfactant or a water-soluble film-forming resin.

[0015] The cationic surfactant is not particularly limited as long as it is commonly used in cosmetics or the like and can be used. For example, lauryl trimethyl ammonium chloride, lauryl trimethyl ammonium bromide, lauroxypropyl trimethyl ammonium chloride, myristyl trimethyl ammonium chloride, myristyl trimethyl ammonium bromide, myristyl propyl trimethyl ammonium chloride, palmityl trimethyl ammonium chloride, palmityl trimethyl ammonium bromide, palmitoyl propyl trimethyl ammonium chloride, stearyl trimethyl ammonium chloride, stearyl trimethyl ammonium bromide, stearoxypropyl trimethyl ammonium chloride, behenyl trimethyl ammonium chloride, behenyl trimethyl ammonium bromide, behenyl propyl trimethyl ammonium chloride, behenyl PG-trimonium chloride and other monoalkyl trimethyl ammonium type surfactants, dialkyl dimethyl ammonium chloride, dialkyl dimethyl ammonium bromide, dialauroxypropyl dimethyl ammonium chloride, dimyristyl dimethyl ammonium chloride, dimyristyl dimethyl ammonium bromide, dipalmityl dimethyl ammonium chloride, dipalmityl dimethyl ammonium bromide, distearyl dimethyl ammonium chloride, distearyl dimethyl ammonium bromide, dibehenyl dimethyl ammonium chloride, dibehenyl dimethyl ammonium bromide and other dialkyl dimethyl ammonium type surfactants, dicocoyl ethyl hydroxyethyl monium chloride, dicocoyl ethyl hydroxyethyl monium methosulfate, dicocoyl ethyl hydroxyethyl monium methophosphate and other dicocoyl ethyl hydroxyethyl monium type surfactants can be mentioned. In addition, those in which polyoxyethylene (sometimes described as PEO) is added to the surfactant may also be used. In the present invention, from the viewpoint of the effect of suppressing fading under high humidity conditions of dyed hair, it is preferable to use one or more selected from monoalkyl trimethyl ammonium type surfactants, dialkyl dimethyl ammonium type surfactants, and dicocoyl ethyl hydroxyethyl monium type surfactants, and it is more preferable to use dialkyl dimethyl ammonium type surfactants.

[0016] The monoalkyltrimethylammonium type surfactant is a quaternary ammonium type surfactant, and the hydrophobic group is a monoalkyl type or monoalkyl ether type surfactant. Regarding the number of carbon atoms in the alkyl chain, there is no particular limitation as long as it can be normally used in cosmetics, but preferably it has 12 to 22 carbon atoms, more preferably 14 to 22 carbon atoms, and even more preferably 16 to 22 carbon atoms. Specifically, it is more preferable to use one or more selected from stearyltrimethylammonium chloride, behenyltrimethylammonium chloride (behentrimonium chloride), and behenyl PG trimonium chloride.

[0017] The dialkyldimethylammonium type surfactant is a quaternary ammonium type surfactant, and the hydrophobic group is a monoalkyl type or monoalkyl ether type surfactant.

[0018] For the dicocoylethylhydroxyethylmonium type surfactant, dicocoylethylhydroxyethylmonium methosulfate is preferred. Since dicocoylethylhydroxyethylmonium methosulfate can form stable vesicle particles by itself, it can be made into a composition having excellent fading suppression effect under high humidity conditions for dyed hair, which combines the effects of vesicle particles such as skin permeability. Also, the method for forming the vesicle particles is not particularly limited and can be produced by conventional methods, and the method for confirming the vesicle particles can be carried out by, for example, the presence or absence of Maltese cross images under crossed Nicols using a polarizing microscope.

[0019] The water-soluble film-forming resin is not particularly limited as long as it is usually used in cosmetics or the like, and can be used, and can be appropriately obtained from commercially available products or known production methods. Examples of the water-soluble film-forming resin include cationic, anionic, amphoteric, and nonionic film-forming resins, and one or more selected from these can be used.

[0020] In the present invention, "film formation" preferably means that a solution in which 40% of the corresponding component is dissolved in a soluble solvent is applied to a glass plate with an applicator having a thickness of 400 μm and a film is formed after drying at room temperature for 24 hours.

[0043] Reference Example 1 Fading test of dyed hair (red): As human hair tresses, test hair tresses (1 g, length 10 cm, light brown (manufactured by Staffs)) were used. These test hair tresses were dyed using the following dye (red oxidation dye). For the dyeing, the agent 1 and agent 2 of the oxidation dye were mixed at a mass ratio of 1:1 to prepare a dyeing chemical solution. This chemical solution was applied to the human hair tresses while spreading it uniformly at about 9 g, left for 20 minutes, and then washed away with warm water until the color of the chemical solution disappeared. Thereafter, it was washed with the shampoo for evaluation having the following formulation, rinsed, and then dried sufficiently with a dryer to prepare dyed hair. This dyed hair was placed in an environment of room temperature (25°C), relative humidity 40%, relative humidity 60% or relative humidity 80% for 1 week (the appearance of the dyed hair after 1 week is shown in FIG. 1). Before and after the start of the test, the hair tresses were colorimetrically measured by the method shown below, and the color difference ΔE was calculated. The results are shown in Table 1.

[0049] From these results, it became clear that the dyed hair fades under high humidity conditions.

[0050] Test Example 1 Fading Inhibition Test of Dyed Hair (Red): Red-dyed hair was prepared in the same manner as in Reference Example 1. On the day after hair dyeing, 5 drops (about 0.15 ml) of the following samples were evenly applied to the dyed hair (if it contained moisture, it was dried with a dryer), and then hung in a thermostatic chamber at a temperature of 25°C and a relative humidity of 80%. After one week, it was collected, and the samples, including those not applied, were washed with a shampoo for evaluation and dried with a dryer. In the same manner as in Reference Example 1, each dyed hair before and after the test was color-measured with a spectrophotometer to obtain the color difference ΔE, and the ΔE (relative evaluation) of the dyed hair applied with each sample was calculated when the ΔE of the dyed hair without sample application (Comparative Example 1) was set to 1, and the fading suppression effect was evaluated according to the following evaluation criteria. The results are shown in Table 2.
