Description

The present invention relates to a hair treatment set and a hair treatment composition. More specifically, the present invention relates to a hair treatment set and a hair treatment composition suitable for improving hair frizz.

Hair is damaged on a daily basis by washing with shampoos and other cleansing agents and drying with hair dryers. In addition, in recent years, as hairstyles have become more diverse, it has become common to subject hair to chemical treatments such as dyeing, bleaching, and perming. These chemical treatments also damage hair. Furthermore, it is known that the texture of hair changes with age.

Hair becomes wavy due to damage caused by chemical treatments such as dyeing and bleaching, damage caused by physical treatments such as heat and friction, and changes in hair texture due to aging. As the amount of wavy hair increases, the hair becomes dry and spreads out. In addition, as the amount of wavy hair increases, the texture of the hair, such as the overall shine, feel, and manageability, deteriorates.

To address the above-mentioned problems, hair treatments containing specific compounds have been proposed. For example, Patent Document 1 describes how hair frizz can be improved by hardening the hair using a hair treatment composition containing an aspartame component.

Patent Document 2 describes how frizz in hair can be improved by using a hair cosmetic that combines a first agent containing a specific cationic polymer with a second agent containing a specific phosphorylcholine group-containing polymer.

JP 2013-103882 A JP 2017-190290 A

The techniques described in Patent Documents 1 and 2 apply a hair treatment agent to the surface of the hair to harden the hair in order to suppress hair frizz. The hair compositions described in Patent Documents 1 and 2 tend to make the hair hard. In addition, the effect of the hair treatment agent attached to the surface of the hair is not long-lasting.

The present invention aims to provide a hair treatment set and a hair treatment composition suitable for improving hair frizz.

The present invention relates to
A composition A containing an anionic acrylic polymer, an anionic surfactant, and a hydrolyzed protein or a derivative thereof;
and composition B comprising a cationic surfactant;
To provide a hair treatment set.

From another aspect, the present invention provides
The composition includes an anionic acrylic polymer, an anionic surfactant, and a hydrolyzed protein or a derivative thereof.
A hair treatment composition is provided.

The hair treatment set and hair treatment composition of the present invention are suitable for improving hair frizz.

The following describes an embodiment of the present invention. The present invention is not limited to the following embodiment.

(Composition A)
The composition A according to the present embodiment includes an anionic acrylic polymer. The anionic acrylic polymer may be an anionic polymer or a salt thereof, which contains at least one monomer selected from the group consisting of acrylic acid, methacrylic acid, alkyl acrylate, alkyl methacrylate, hydroxyalkyl acrylate, and hydroxyalkyl methacrylate. The anionic acrylic polymer may have a structure in which polymers containing at least one monomer selected from the group consisting of acrylic acid, methacrylic acid, alkyl acrylate, alkyl methacrylate, hydroxyalkyl acrylate, and hydroxyalkyl methacrylate are crosslinked with each other.

The anionic acrylic polymer may have an anionic functional group. Examples of the anionic functional group are a carboxy group, a phosphate group, and a sulfonic acid group.

The number of carbon atoms in the alkyl group contained in the alkyl acrylate, alkyl methacrylate, hydroxyalkyl acrylate, or hydroxyalkyl methacrylate is not limited to a specific value and may be 10 or more and 30 or less. The alkyl group may be linear or branched. The alkyl group may be a saturated or unsaturated hydrocarbon group.

Examples of anionic acrylic polymers are acrylates/alkyl acrylate (C10-30) crosspolymer, hydroxyethyl acrylate/sodium acryloyldimethyltaurate copolymer, carbomer, acrylates copolymer, sodium polyacrylate, and sodium alkyl acrylate copolymer. The acrylates/alkyl acrylate (C10-30) crosspolymer refers to a polymer in which a copolymer of acrylic acid or methacrylic acid and an alkyl acrylate is crosslinked with an ether such as an allyl ether of sucrose or an allyl ether of pentaerythritol. The alkyl acrylate (C10-30) refers to an ester of acrylic acid and an alkyl group having 10 to 30 carbon atoms. The acrylates copolymer refers to a copolymer composed of at least two monomers selected from the group consisting of alkyl acrylate (C1-4), alkyl methacrylate (C1-4), acrylic acid, and methacrylic acid. As the anionic acrylic polymer, only one selected from these anionic acrylic polymers may be used, or two or more may be used in combination.

The content of the anionic acrylic polymer relative to the total mass of composition A is not limited to a specific value, and may be 0.001% by mass to 2.0% by mass, 0.005% by mass to 1.5% by mass, or even 0.01% by mass to 1.0% by mass.

Composition A contains an anionic surfactant. By containing an anionic surfactant, the hydrolyzed protein described later can be easily penetrated into the inside of the hair. Examples of anionic surfactants are polyoxyalkylene alkyl ether phosphate, N-acyl glutamic acid, alkyl sulfate, and derivatives thereof. A preferred example of polyoxyalkylene alkyl ether phosphate is polyoxyethylene alkyl ether phosphate. The number of carbon atoms in the alkyl group contained in the polyoxyethylene alkyl ether phosphate is not limited to a specific value, and may be 12 to 22, 14 to 20, or even 16 to 20. Examples of polyoxyethylene alkyl ether phosphate are polyoxyethylene lauryl ether phosphate, polyoxyethylene cetyl ether phosphate, polyoxyethylene stearyl ether phosphate, polyoxyethylene cetearyl ether phosphate, and salts thereof. Examples of polyoxyethylene lauryl ether phosphate are laureth-2 phosphate, laureth-4 phosphate, dilaureth-10 phosphate, and trilaureth-4 phosphate. Examples of polyoxyethylene cetyl ether phosphate are ceteth-10 phosphate and ceteth-20 phosphate. Examples of polyoxyethylene stearyl ether phosphate are steareth-2 phosphate and steareth-3 phosphate. An example of polyoxyethylene cetearyl ether phosphate is triceteareth-4 phosphate. Examples of N-acyl glutamic acid and its salts are sodium N-lauroyl glutamate, sodium N-stearoyl glutamate, arginine N-stearoyl glutamate, and sodium N-myristoyl glutamate. Examples of alkyl sulfates are sodium lauryl sulfate and sodium cetyl sulfate. Only one selected from these anionic surfactants may be used, or two or more may be used in combination.

A preferred example of an anionic surfactant is polyoxyethylene alkyl ether phosphate having an alkyl group with 12 to 22 carbon atoms. By using polyoxyethylene alkyl ether phosphate having an alkyl group with 12 to 22 carbon atoms as the anionic surfactant, it becomes easier to ensure that the hydrolyzed protein described below penetrates into the hair. As a result, in addition to improving hair frizz, it is possible to more reliably improve the texture of the hair, such as shine and ease of running your fingers through it.

The content of the anionic surfactant relative to the total mass of composition A is not limited to a specific value, and may be 0.005% by mass to 8.0% by mass, 0.01% by mass to 6.0% by mass, or even 0.05% by mass to 4.0% by mass.

Composition A contains a hydrolyzed protein or a derivative thereof. The hydrolyzed protein or a derivative thereof easily penetrates into the interior of the hair, making it possible to improve wavy hair from the inside of the hair. In addition, the inclusion of a hydrolyzed protein or a derivative thereof in composition A can improve the texture of the hair. Furthermore, the inclusion of a hydrolyzed protein or a derivative thereof and an anionic surfactant in composition A makes it easier for the hydrolyzed protein to penetrate more reliably into the interior of the hair. In this way, the inclusion of a hydrolyzed protein or a derivative thereof in composition A provides an improvement effect against hair wavy hair, and also tends to improve the texture of the hair.

A hydrolyzed protein is a peptide compound obtained by hydrolyzing a protein. For example, a hydrolyzed protein is a hydrolyzate of a naturally derived protein (PPT). Examples of hydrolyzed proteins are hydrolyzed keratin, hydrolyzed silk, hydrolyzed almond protein, hydrolyzed casein, hydrolyzed oat protein, hydrolyzed yeast protein, hydrolyzed collagen, hydrolyzed conchiolin, hydrolyzed lupin protein, hydrolyzed soybean protein, hydrolyzed pea protein, hydrolyzed corn protein, hydrolyzed milk protein, hydrolyzed honey protein, hydrolyzed hazelnut protein, hydrolyzed jojoba protein, hydrolyzed vegetable protein, hydrolyzed royal jelly protein, hydrolyzed wheat protein, and hydrolyzed rice protein. Only one selected from these hydrolyzed proteins may be used, or two or more may be used in combination.

A preferred example of a hydrolyzed protein is hydrolyzed keratin. Hydrolyzed keratin penetrates more reliably into the interior of hair. As a result, it is possible to more reliably achieve an improvement effect against hair frizz.

Hydrolyzed protein derivatives refer to proteins that have been chemically modified by silylation, acylation, cationization, or the like. Examples of silylated hydrolyzed proteins are (dihydroxymethylsilylpropoxy) hydroxypropyl hydrolyzed silk, (dihydroxymethylsilylpropoxy) hydroxypropyl hydrolyzed soy protein, (dihydroxymethylsilylpropoxy) hydroxypropyl hydrolyzed wheat protein, (dihydroxymethylsilylpropoxy) hydroxypropyl hydrolyzed collagen, hydrolyzed sesame protein PG propyl methylsilanediol, and (dihydroxymethylsilylpropoxy) hydroxypropyl hydrolyzed keratin. Examples of acylated hydrolyzed proteins are lauroyl hydrolyzed silk, isostearoyl hydrolyzed silk, cocoyl hydrolyzed soy protein, palmitoyl hydrolyzed wheat protein, cocoyl hydrolyzed collagen, undecylenoyl hydrolyzed collagen, isostearoyl hydrolyzed collagen, and rosin hydrolyzed collagen. Examples of cationic hydrolyzed proteins are hydroxypropyltrimonium hydrolyzed silk, cocodimonium hydroxypropyl hydrolyzed silk, hydroxypropyltrimonium hydrolyzed wheat protein, cocodimonium hydroxypropyl hydrolyzed wheat protein, hydroxypropyltrimonium hydrolyzed collagen, cocodimonium hydroxypropyl hydrolyzed collagen, hydroxypropyltrimonium hydrolyzed casein, cationized hydrolyzed conchiolin, and hydroxypropyltrimonium hydrolyzed keratin. Only one selected from these hydrolyzed protein derivatives may be used, or two or more may be used in combination.

The weight average molecular weight of the hydrolyzed protein is not limited to a specific value, and may be 100 or more, preferably 1000 or more, and particularly 10000 or more. The upper limit of the weight average molecular weight of the hydrolyzed protein is not limited to a specific value, and may be 100000, 80000, or even 50000. When the hydrolyzed protein has an appropriate weight average molecular weight, the effect of improving hair frizz becomes significant.

The content of hydrolyzed protein relative to the total mass of composition A is not limited to a specific value, and may be 0.005% by mass to 8.0% by mass, 0.01% by mass to 6.0% by mass, or even 0.05% by mass to 4.0% by mass.

Composition A may further contain a higher alcohol. By including a higher alcohol, composition A can be obtained that has cream-like properties, and the texture of hair can be improved more reliably.

The number of carbon atoms of the higher alcohol is not particularly limited, and may be 8 to 30, or 14 to 22. The higher alcohol may be a saturated alcohol or an unsaturated alcohol. Examples of higher alcohols are lauryl alcohol, myristyl alcohol, cetyl alcohol, stearyl alcohol, cetearyl alcohol, oleyl alcohol, and behenyl alcohol. Only one selected from these higher alcohols may be used, or two or more may be used in combination.

The content of higher alcohol relative to the total mass of composition A is not limited to a specific value, and may be 0.01% by mass to 10.0% by mass, 0.05% by mass to 7.5% by mass, or even 0.1% by mass to 5.0% by mass.

Composition A is, for example, weakly acidic to weakly alkaline. The pH of composition A at 25°C may be, for example, 5.0 or more, 5.5 or more, or even 6.0 or more, and may be 8.0 or less, or even 7.5 or less. When composition A has an appropriate pH, the anionic acrylic polymer contained in composition A can have excellent stability. In addition, when composition A has an appropriate pH, hair is less likely to be damaged, and the texture of hair can be more reliably improved.

The pH adjuster for adjusting the pH of composition A may be any pH adjuster typically used in hair treatments. Examples of pH adjusters include phosphoric acid, lactic acid, guanidine carbonate, sodium dihydrogen phosphate, trisodium phosphate, sesquicarbonate, arginine, sodium bicarbonate, sodium carbonate, monoethanolamine, ammonia, 2-amino-2-methyl-1-propanol, sodium hydroxide, tripotassium citrate, trisodium citrate, and diammonium hydrogen phosphate.

The formulation of Composition A is not limited to a specific formulation, and any known formulation may be used. Preferred formulations are gel, solution, cream, or emulsion, and more preferably cream. When Composition A is in cream form, it is easier to more reliably achieve the effect of reducing frizz, and the texture of the hair can be more reliably improved.

As described above, composition A includes an anionic acrylic polymer, an anionic surfactant, and a hydrolyzed protein. The ratio of the contents of each component contained in composition A is not limited to a specific value. In composition A, the ratio of the content of the hydrolyzed protein to the content of the anionic surfactant may be 0.05 to 20, or even 0.1 to 10, by mass. In composition A, the ratio of the content of the anionic acrylic polymer to the content of the anionic surfactant may be 0.01 to 10, or even 0.05 to 5, by mass. In composition A, the ratio of the content of the anionic acrylic polymer to the content of the hydrolyzed protein may be 0.01 to 10, or even 0.05 to 5, by mass.

(Composition B)
Composition B according to the present embodiment contains a cationic surfactant. By containing a cationic surfactant, hair can be softened, so that hair frizz can be more reliably improved. In addition, by containing a cationic surfactant, hair texture can be more reliably improved.

The cationic surfactant is not limited to a specific type, so long as it is a cationic surfactant that is normally used in hair cosmetics. Examples of cationic surfactants are alkyl quaternary ammonium salts, alkenyl quaternary ammonium salts, alkylamine salts, and fatty acid amide amine salts.

Only one of these cationic surfactants may be used, or two or more of them may be used in combination.

The content of the cationic surfactant relative to the total mass of composition B is not limited to a specific value, and may be 0.01% by mass to 10.0% by mass, 0.05% by mass to 7.5% by mass, or even 0.1% by mass to 5.0% by mass.

Composition B may further contain a higher alcohol. By including a higher alcohol, it is possible to obtain composition B having creamy properties, and it is possible to more reliably improve the texture of hair. As the higher alcohol, the one described above can be used.

The content of higher alcohol relative to the total mass of composition B is not limited to a specific value, and may be 0.01% by mass to 15.0% by mass, 0.1% by mass to 10.0% by mass, or even 0.5% by mass to 7.5% by mass.

Composition B may further contain silicone. By including silicone, the feel of the hair can be further improved.

Examples of silicones are dimethicone, dimethiconol, and amino-modified silicone. Only one of these silicones may be used, or two or more of them may be used in combination.

Examples of amino-modified silicones are aminopropylmethylsiloxane-dimethylsiloxane copolymer (aminopropyldimethicone), aminoethylaminopropylsiloxane-dimethylsiloxane copolymer (amodimethicone), and aminoethylaminopropylmethylsiloxane-dimethylsiloxane copolymer (trimethylsilylamodimethicone).

A preferred example of silicone is amino-modified silicone. As mentioned above, amino-modified silicone has a cationic functional group, so it can more reliably improve the texture of hair.

The content of silicone relative to the total mass of composition B is not limited to a specific value, and may be 0.01% by mass to 15.0% by mass, 0.1% by mass to 10.0% by mass, or even 0.5% by mass to 5.0% by mass.

The formulation of composition B is not limited to a specific formulation, and any known formulation can be used. The formulation of composition B may be the same as or different from the formulation of composition A. Preferred formulations are gel, solution, cream, or emulsion, and more preferred is cream. When composition B is in cream form, it becomes easier to reliably obtain the effect of improving hair frizz.

(Other ingredients)
Compositions A and B may contain any component other than the above-mentioned components. The optional component may be a component contained in a known hair treatment agent.

An example of an optional component is a cationic polymer. A cationic polymer means, for example, a polymer having a cationic functional group, such as a quaternary ammonium group, in the molecule. A cationic polymer can typically be a polymer containing an amino group or a quaternary ammonium group in a side chain of a polymer chain. Examples of cationic polymers are cationic cellulose and vinyl or (meth)acrylic polymers or copolymers having quaternary ammonium side chains. Examples of cationic cellulose are polyquaternium-4, polyquaternium-10, and polyquaternium-67. An example of a vinyl or (meth)acrylic polymer or copolymer having quaternary ammonium side chains is polyquaternium-37.

One example of an optional ingredient is a nonionic surfactant. Examples of nonionic surfactants are polyoxyethylene alkyl ethers, polyoxyethylene sorbitan fatty acid esters, sorbitan fatty acid esters, polyoxyethylene hydrogenated castor oil, alkyl glucosides, glyceryl stearate, and coconut oil fatty acid diethanolamide.

As mentioned above, composition A contains an anionic surfactant and hydrolyzed protein. This makes it possible to repair damage inside the hair. Furthermore, the cationic surfactant contained in composition B acts to fix the hydrolyzed protein inside the hair. As a result, these components are less likely to flow out of the hair. Hair treated with a hair treatment set containing hydrolyzed protein has an excellent effect of improving hair frizz, and the effect is also excellent in durability.

Composition A also contains an anionic acrylic polymer. Therefore, by applying the anionic acrylic polymer to the hair, damage to the surface of the hair can be repaired. This improves the texture of the hair. The hair treatment set according to this embodiment makes it possible to repair the inside and surface of the hair. This results in a significant improvement in hair frizz, and improves the texture of the hair. As far as the inventors know, a hair treatment that repairs not only the surface of the hair but also the inside of the hair has not been known until now.

Next, we will explain how to treat hair using the hair treatment set.

The method of contacting compositions A and B with hair is not limited to a specific method, and compositions A and B may be applied directly to hair by hand, or may be applied to hair using an application tool such as a comb, brush, paintbrush, or spray. Compositions A and B may be applied to dry hair or to wet hair.

In the treatment method using the hair treatment agent set according to this embodiment, a step of removing the hair treatment agent may be included between hair treatment with composition A and hair treatment with composition B, or after contacting the hair with composition A, composition B may be contacted with the hair without removing composition A. After contacting the hair with composition B, a step of removing composition B may be included, or a step of removing composition B may not be included. Composition A or B can be removed, for example, by rinsing with water or by washing the hair with a cleaning agent such as shampoo.

In the treatment method using the hair treatment set according to this embodiment, the order of hair treatment with composition A and hair treatment with composition B is not limited to a specific order. Hair that has been treated with composition A may be treated with composition B, and hair that has been treated with composition B may be treated with composition A. The number of times hair is treated with compositions A and B is also not limited to a specific number of times. Compositions A and B may be applied alternately to the hair.

The present invention will be described below based on examples. Note that the present invention is not limited to these examples, and these examples can be modified or changed based on the spirit of the present invention, and are not excluded from the scope of the invention.

Lactic acid was then added to the cream-like composition B to adjust the pH of the composition B at 25° C. to 4.5. All units in the tables are mass %.

<Evaluation>
The prepared hair bundle for evaluation was washed with warm water, thoroughly moistened, and then the prepared composition A (1 g) according to the examples and comparative examples was applied uniformly to the hair bundle. Subsequently, the prepared composition B (1 g) according to the examples and comparative examples was applied uniformly to the hair bundle. The hair bundle was washed with warm water to wash off the composition, and after towel drying, the hair bundle was dried with a hair dryer. The dried hair bundle was subjected to a sensory evaluation by 10 beauty professionals for "improvement of waviness,""luster,""ease of running fingers through the hair," and "goodness of fit." The evaluation was made on a 5-point scale of "good: 5 points, slightly good: 4 points, normal: 3 points, slightly bad: 2 points, bad: 1 point," and was judged based on the following criteria using the average score of the 10 beauty professionals. The results are shown in Tables 1 to 4.
◎: Very good: Average value is 4.5 points or more ○: Good: Average value is 3.5 points or more and less than 4.5 points △: Poor: Average value is 1.5 points or more and less than 3.5 points ×: Very bad: Average value is less than 1.5 points

In each of the examples, an improvement was achieved in terms of hair frizz. In addition, in each of the examples, good results were also achieved in terms of hair texture. In particular, the inclusion of hydrolyzed protein in composition A resulted in a significant improvement in terms of hair frizz and improved hair texture. On the other hand, in each of the comparative examples, hair frizz could not be sufficiently improved. In addition, in each of the comparative examples, hair texture could not be improved.
