Disclosure of Invention

Problems to be solved by the invention

Hair colorant means a colorant which contains several pigments and changes the color of hair by attaching its pigment to the surface of hair. Since pigments tend to settle and aggregate during storage, when a hair coloring material is used, it is necessary to shake the container to disperse the pigments uniformly again before use, but the dispersibility of the pigments is poor during shaking mixing, and if the pigments are not sufficiently dispersed, the problem arises that the applied hair color tone is not uniform.

Accordingly, the present invention focuses on the dispersibility of the pigment when the hair coloring material is mixed with shaking, and aims to improve the dispersibility. That is, an object of the present invention is to provide a spray-type hair colorant composition which has excellent pigment dispersibility when shaking-mixed and can be applied to hair with a balanced pigment color tone.

Means for solving the problems

The present inventors have conducted intensive studies to solve the above problems, and as a result, have found that the dispersibility of a pigment can be improved during shaking mixing by adding the pigment and a cationic polymer to a spray-type hair colorant composition, thereby completing the present invention.

That is, the present invention is a spray-type hair colorant composition characterized by containing the following pigments and cationic polymers.

The spray-type hair colorant composition of the present invention for solving the above problems is characterized by containing (a) a pigment and (B) a cationic polymer.

The following is a detailed description of embodiments of the spray type hair colorant composition according to the present invention.

The spray type hair colorant composition described in the present embodiment is merely an example for illustrating the present invention, and is not limited thereto.

[ spray-type Hair dye composition ]

The spray type hair colorant composition in the present invention is a composition which is applied to hair by using a device for spraying a liquid in a state of mist, bubbles or the like by a gas such as high-pressure air or a mechanical motion (a finger, a piezoelectric element or the like) and has a coloring mechanism for temporarily adhering various pigments to hair by physical adhesion force to color hair.

The spray type hair colorant composition of the present invention can be applied to hair using a propellant such as a gas such as high-pressure air, a liquefied gas, or a compressed gas. The ratio of the spray liquid containing the pigment (a) and the cationic polymer (B) to the propellant is not particularly limited, and may be appropriately set according to the target spray form, and examples thereof include: propellant =20: 80-80: 20. when the ratio of the propellant is 20 or more, the propellant can be reliably discharged, and the pigment can be uniformly applied to the hair. When the ratio of the spraying agent is 80 or less, the spraying force is appropriate, and it is possible to prevent the coloring agent such as pigment from scattering and contaminating clothes and the surrounding environment.

The components constituting the spray type hair colorant composition of the present invention will be described in detail below.

< pigments >

The pigment is a powder for coloring and is insoluble in water or oil, and the pigment in the present invention is used for coloring hair.

The type of the pigment is not particularly limited, and examples thereof include inorganic pigments, organic pigments, dye resin solid solutions, daylight fluorescent pigments, natural pigments, and the like. These pigments may be used in a suitable combination of 1 type or 2 or more types depending on the desired hair color tone.

The inorganic pigment is also called a mineral pigment, and is a chemical inorganic pigment. The pigment may be a natural mineral itself, a pigment obtained by processing or pulverizing a natural mineral, or a pigment obtained by using a compound of zinc, titanium, lead, iron, copper, chromium, or the like as a raw material. Has good light resistance and heat resistance and is insoluble in organic solvents. There are various types of pigments, and there are a white pigment (titanium oxide, etc.), a red pigment (indian red, etc.), a yellow pigment (chrome yellow, etc.), a green pigment (emerald green, etc.), a blue pigment (cobalt blue, etc.), a violet pigment (manganese violet, etc.), a black pigment (carbon black, etc.), and a transparent white pigment (silica white, etc.) depending on the color. The inorganic pigment is not particularly limited, and examples thereof include zinc oxide, titanium oxide, indian red, chromium oxide, cobalt oxide, black iron oxide, yellow iron oxide, chromium hydroxide, aluminum hydroxide, beryl blue, barium sulfate, hydrated silicate, anhydrous silicic acid, aluminum silicate, talc, kaolin, carmine, mica, magnesium carbonate, bentonite, ultramarine, manganese violet, carbon black, aluminum, copper, gold, mica titanium, and the like.

The organic pigment is mainly a pigment composed of a coloring matter composed of an organic compound. Organic pigments are roughly classified into organic pigment pigments in which the pigments themselves are insoluble in water; and a lake pigment in which a water-soluble dye is rendered insoluble by some means such as addition of a metal salt. Organic pigments have a rich and clear hue and are excellent in tinting strength and transparency. The organic pigment is not particularly limited, and examples thereof include red pigments 202, 203, 204, 205, 206, 207, 208, 219, 220, 221, 228, and 405; orange numbers 203, 204, 401; yellow 205, 401 numbers; blue 404, etc.

Red No. 202 (lithol Borax BCA) is a legal pigment, and is a monoazo pigment belonging to tar pigments. Red 202 had particularly poor dispersibility when mixed with shaking compared to other pigments.

Red No. 202 (lithol paucin BCA) is a compound having the structure of the following formula (1).

[ CHEM 1 ]

For the number 202 in the color red,the reason why the dispersibility during the shaking mixing is particularly inferior to that of other pigments is not clear, but it is understood that calcium (Ca) is contained in the pigment according to the formula (1). As calcium, it is known that calcium carbonate (CaCO) is added to an aqueous organic acid solution ₃ ) A reaction to precipitate calcium organic acid occurs. It is presumed that red 202, calcium contained therein, also interacts with other components contained in the spray type hair colorant composition, and the dispersibility thereof upon shaking mixing is deteriorated.

The daylight fluorescent pigments are 1 of the fluorescent pigments and are organic pigments. Generally, the color is vivid under light. The brightness is improved by the stimulation of light such as ultraviolet rays.

The natural pigment is not particularly limited, and examples thereof include mineral pigments such as clay, natural dye lakes such as rubia cordifolia or cochineal, azo pigments, and phthalocyanine pigments.

The lower limit is preferably 0.5% by mass or more, and more preferably 1.0% by mass or more. The upper limit is preferably 10% by mass or less, and more preferably 8% by mass or less. When the content of the pigment is 0.1% by mass or more, the coloring effect of the hair can be sufficiently exhibited. When the content of the pigment is 15% by mass or less, the pigment dispersibility can be further improved.

< cationic Polymer >

The cationic polymer is a polymer having a cationized substituent group, and the substituent group includes an amino group, an ammonium group, and the like.

The cationic polymer in the present invention is used to improve the dispersibility of the pigment when mixing with shaking in the spray-type hair colorant composition. The cationic polymer in the present invention has an effect of improving the dispersibility of the pigment, particularly red No. 202, when it is mixed with shaking.

In the present invention, commercially available cationic polymers can be used. The cationic polymer used in the present embodiment is not particularly limited, and examples thereof include cationic polysaccharides and cationic polymers containing a structural unit derived from a cationic monomer. These cationic polymers may be used in a suitable combination of 1 or 2 or more species.

The cationic polysaccharide is a cationic sugar derivative obtained by imparting a cationic group to a polysaccharide. The cationic sugar derivative has a structure in which a part of hydroxyl groups contained in the saccharide is substituted with a quaternary nitrogen-containing group. The quaternary nitrogen-containing group is preferably a quaternary ammonium group, and cationic polysaccharides can be obtained by, for example, reacting saccharides with a quaternary ammonium salt such as glycidyl trialkylammonium salt or 3-halo-2-hydroxypropyltrialkylammonium salt to introduce quaternary ammonium groups into part of the hydroxyl groups of the saccharides.

Examples of the cationic polysaccharide include cationized cellulose, cationized guar gum, cationized tara gum, cationized locust bean gum, cationized cassia seed, cationized fenugreek gum, and cationized starch.

The cationized cellulose is a cellulose-based polymer having a cationic group. Obtained by partially bonding hydroxyethyl cellulose with glycidyl trimethyl ammonium chloride or 3-chloro-2-hydroxypropyl trimethyl ammonium chloride. Specific examples thereof include polyquaternium-4 (hydroxyethylcellulose dimethyldiallylammonium chloride) and polyquaternium-10 (O- [ 2-hydroxy-3- (trimethylamino) propyl ] hydroxyethylcellulose chloride).

The cationized guar gum is prepared by mixing galactose and mannose in a ratio of 1:2, and a water-soluble polymer obtained by quaternizing the methylol and hydroxy groups of mannose in the main chain and galactose in the side chain and cationizing the resulting product. Specific examples thereof include guar hydroxypropyltrimonium chloride and hydroxypropyl guar hydroxypropyltrimonium chloride.

The cationized tara gum is prepared by mixing galactose and mannose in a ratio of 1:3, and a water-soluble polymer obtained by cationic modification of tara gum containing polysaccharides at the ratio of 3. Specific examples thereof include talaroxypropyltrimethylammonium chloride and the like.

The cationized locust bean gum is prepared by mixing galactose and mannose in a ratio of 1:4, and a water-soluble polymer obtained by cationic modification of locust bean gum which is a polysaccharide. Specific examples thereof include locust bean gum hydroxypropyl trimethyl ammonium chloride.

The cationized cassia seed is prepared by adding 1:5, a polysaccharide in the amount of the above-mentioned polysaccharide, and a water-soluble polymer obtained by cationic modification of cassia gum. Specific examples thereof include cassia hydroxypropyltrimethylammonium chloride.

The cationized fenugreek gum is prepared by adding 1:1, a water-soluble polymer obtained by cationic modification of fenugreek gum which is a polysaccharide existing in the ratio of 1. Specific examples thereof include fenugreek hydroxypropyl trimethylammonium chloride.

In addition, the first and second substrates are, the cationized starch is a polymer obtained by cationizing and modifying starch. Specifically, for example, hydroxypropyltrimethylammonium chloride starch and the like are mentioned.

Examples of the cationic monomer in the cationic polymer containing a structural unit derived from the cationic monomer include dimethyldiallylammonium chloride, diethyldiallylammonium chloride, (meth) acrylamidopropyltrimethylammonium chloride, and a sulfate of diethyl dimethylaminoethyl (meth) acrylate (as a sulfate, diethyl sulfate is exemplified), 2- ((meth) acryloyloxy) ethyltrimethylammonium chloride, (meth) acrylamidopropyltrimethylammonium chloride, ethyltrimethylammonium (meth) acrylate, and (meth) acrylamidopropyllauryldimethylammonium chloride. Here, the (meth) acrylamide refers to any one of acrylamide, methacrylamide, and a mixture of acrylamide and methacrylamide. The (meth) acrylic acid refers to any of acrylic acid, methacrylic acid, and a mixture of acrylic acid and methacrylic acid. The (meth) acryloyl group means any of an acryloyl group-containing, a methacryloyl group-containing, and an acryloyl group-containing and methacryloyl group-containing mixture.

Examples of the cationic polymer containing a structural unit derived from the cationic monomer include polydimethylmethylenepiperidinium chloride such as polyquaternium-6, dimethyldiallylammonium chloride-acrylamide copolymers such as polyquaternium-7, vinylpyrrolidone N, N-dimethylaminoethylmethacrylate copolymer diethylsulfate such as polyquaternium-11, vinylpyrrolidone-methylvinylimidazolium copolymers such as polyquaternium-16, and ethyl [ (methacryloyloxy) ethyl ] dimethylammonium ethylsulfate N, N-dimethylacrylamide-polyethylene glycol dimethacrylate copolymers such as polyquaternium-52. Among the above cationic polymers, cationic acrylic resins are preferred from the viewpoint of improving dispersibility of red No. 202.

The content of the cationic polymer in the present invention is not particularly limited, and is, for example, 0.01 to 10% by mass. The lower limit of the content is preferably 0.1% by mass or more, and more preferably 0.5% by mass or more. The upper limit of the content is preferably 5% by mass or less, and more preferably 3% by mass or less. Thereby, the color paste is formed integrally with the pigment, and the dispersibility of the pigment can be further improved.

The cationic polymer can improve the dispersibility of the pigment during shaking mixing, but is considered to be particularly effective for pigments having a property of being likely to be anionic among pigments. For example, red 202 has a structure represented by formula (1) and has a phenolic hydroxyl group in the structure. Since phenolic hydroxyl groups are relatively likely to be anions, red 202 is considered to be likely to exhibit anionic properties. In this case, it is assumed that the pigment dispersion of red 202 and the like is improved in the shaking mixing because the pigment is likely to interact with the cationic polymer and the aggregation and the like of the red 202 particles can be controlled by the interaction with the cationic polymer.

As described above, it is estimated that the dispersibility in the spray type hair colorant composition is deteriorated by the interaction between calcium contained in red No. 202 and other components contained in the composition, but the cationic polymer is likely to interact with the cationic polymer because of the phenolic hydroxyl group, and therefore, the cationic polymer is expected to exert an effect of improving the dispersibility particularly in the spray type hair colorant composition of red No. 202.

The pigment which easily exhibits the effect of improving dispersibility by the cationic polymer when mixed with shaking is described using red 202, but is not limited to red 202. It is considered that, for example, if the pigment has a structure which is relatively likely to be anionic, such as a structure containing a phenolic hydroxyl group, the effect of the cationic polymer to improve dispersibility during shaking mixing is likely to be exhibited.

The lower limit of the content is preferably 0.1% by mass or more, and more preferably 0.5% by mass or more.

As shown in tables 1 and 2, the evaluation results of the easy dispersibility of the spray type hair colorant composition of the present invention in examples were 3 to 5, and good results were shown.

Examples 1 and 4 and comparative example 1 were the same except that they contained only a cationic polymer (B). The evaluation results of comparative examples 1 and 4 and comparative example 1 showed that the dispersibility was different, and that comparative example 1 was "1", example 1 was "5", and example 4 was "4", which showed good results. From this, it is understood that the cationic polymer (B) can improve the dispersibility of the pigment during shaking mixing.

It is understood from comparative example 2 and comparative example 2 that the difference between the two is whether or not the cationic polymer (B) is contained, and the result is good in comparative example 2 where the dispersibility is easy "2", and in example 2 where "5". In example 1, example 2, comparative example 1 and comparative example 2, the total content of the pigment (a) was not changed, but example 1 and comparative example 1 contained red 202 as the pigment (a), but example 2 and comparative example 2 did not. Here, as is clear from comparison between comparative example 1 and comparative example 2, comparative example 1 containing red 202 is inferior in easy dispersibility, and the evaluation of easy dispersibility is the same between example 1 and example 2. From this fact, it is found that red 202 has poorer dispersibility when shaking and mixing than other pigments, and that (B) the cationic polymer can exert a good effect for eliminating the poor dispersibility of red 202.

Comparing example 1 with example 4, it is clear that, although different compounds were used as (a) the cationic polymer, the evaluation of the easy dispersibility was good. Therefore, it is understood that different compounds can be used as the cationic polymer (a) in the spray type hair colorant composition of the present invention. Further, as for the evaluation of easy dispersibility, it is understood that the copolymer of butyl methacrylate, ethoxyethyl methacrylate, methacryloyloxyethyl trimethylammonium chloride is more preferable as the cationic polymer (a) in the case where example 1 is "5" and example 4 is "4".

Comparing example 1, example 3 and example 10, it is clear that example 1 and example 10 contain an amphoteric resin or an anionic resin, which is different from example 3. The evaluation of easy dispersibility in examples 1 and 10 was good, and therefore the amphoteric resin or anionic resin could further improve the dispersibility of the (a) pigment during shaking mixing.

It is clear from comparative examples 5 to 9 that when the content mass ratio (B/A) of the (B) cationic polymer to the (A) pigment is high, the dispersibility is improved.
