Description

Hair styling composition

The present application relates to hair styling compositions.

A variety of products are available for hair styling. For example, hair sprays, gels, mousses, hair tonics, hair lotions and the like are sold. These products contain ingredients (compositions) that maintain the hair designed for the desired time after contact with the hair.

As a hair spray, for example, the hair spray composition (aerosol) may include a high pressure gas propellant, a solvent and a polymer for hair setting, a plasticizer, a humectant, and / or a fragrance providing component, and the like. The composition is stored in a predetermined spray system. For example, when the user presses a spray button formed on the spray container, the composition may be sprayed onto the hair in the form of gas-containing fine particles, foam or liquid by means of a high pressure gas propellant (eg LPG), The hair sprayed with the composition can be designed (or set) in the desired shape. The polymer for hair setting in the composition of the composition is a component that provides a hair setting holding force (or holding force) for a predetermined time with respect to the hair part set by the user after the composition is injected. More specifically, when the solvent (eg, liquefied gas such as ethanol or LPG) evaporates after the spray composition is sprayed on the hair, the polymer for hair setting forms a film on the surface of the hair. Hair can be fixed in the set state by).

As the polymer for hair setting to perform the above action, a polymer soluble in water or alcohol is used. For example, polyvinylpyrrolidone, vinylpyrrolidone / vinylacetate copolymers, vinylacetate / crotonic acid copolymers, or acrylic resins are widely used as the polymer for hair setting. The polymer is easy to provide a fixation effect on the hair after being injected into the hair by the hardness of the polymer, but has the disadvantage of being overly rigid or rough and sticky in view of its use with various additives. That is, it does not provide a good aesthetic or touch. And the polymer as described above is inflexible (flexibility), so that when the combing after spraying or when external force is applied to the fixed hair, the coated polymer film is broken and white powder is observed (hereinafter referred to as flakeing (fliaking)) ).

Recently, a method of using a silicon grafted organic backbone polymer in hair styling products has been introduced. For example, Patent Publication No. 1999-0067122, Patent Publication No. 2001-0030417, and Patent Publication No. 1991-002421 propose techniques that use silicone grafted polymers to provide hair styling retention and improved hair feel. However, these compositions usually look like particles sprayed from the container are sprayed on the hair while forming bubbles, so that particles such as white eye powder or white beads are sprayed on the black hair (hereinafter referred to as beading). .

One object of the present application is to provide a hair styling composition that can improve the flaking phenomenon and the beading phenomenon.

Another object of the present application is to provide a hair styling composition excellent in taste and touch.

Another object of the present application is to provide a hair styling composition excellent in cleanability.

Another object of the present application is to provide a hair styling composition for hairspray.

The above and other objects of the present application can all be solved by the present application described in detail below.

In one example of the present application, the present application relates to a hair styling composition used to contact hair through an injection, spray or pumping system and to fix the hair in a predetermined form. The composition comprises a polymer of a predetermined configuration. Thus, the composition provides a good aesthetics and feel while maintaining the setting state formed by the user for a long time, improves the beading or flaking phenomenon, and provides excellent cleanability after use.

The composition includes a polymer having a unit represented by the following formula (1). Both ends of Formula 1 may be linked with other chains. The polymer of the following composition makes it possible to provide the hair setting holding force for a predetermined time for the hair part set by the user, and excellent solubility in solvents, even coating property on the hair, and excellent cleansing property when washing the hair after use to provide.

[Formula 1]

In Chemical Formula 1,

X ₁ , X ₂ , and X ₃ are each independently hydrogen or an alkyl group,

R ₁ is an alkyl group,

A ₁ and A ₂ are alkylene groups having the same or different carbon atoms,

n is an integer from 1 to 50,

R ₂ is hydrogen or an alkyl group,

X ⁺ and Y ⁻ are cationic residues and anionic residues, respectively

a, b, and c are greater than 0 as the average degree of polymerization of each polymerized unit, and a + b + c has a value between 50 and 1,000.

Unless specifically defined in the present application, an alkyl group may mean an alkyl group having 1 to 20 carbon atoms, and an alkylene group may mean an alkylene group having 1 to 20 carbon atoms. The alkyl group or alkylene group may be linear or branched, and may be substituted with one or more optional substituents.

The polymer is a cationic acrylic polymer. That is, in the polymer having a unit represented by Chemical Formula 1, Y ⁻ is not attached to the polymer and is movable while maintaining an ionic balance.

In the general formula (I), in relation to X ⁺ and Y ⁻ , a cationic moiety or an anionic moiety refers to an ionic moiety derived from the monomer remaining in the polymer after the monomer used to copolymerize the polymer participates in the polymerization reaction. it means.

In one example, X ⁺ may be one or more selected from the group consisting of imidazolium, ammonium, pyridinium, triazium, and phosphonium.

In one example, the Y ^- is F ^- may be at least one selected from the group consisting of ^-, Cl ^-, Br ^-, and I.

When the degree of polymerization is satisfied, the units having an average polymerization number of a and b contribute to the improvement of the beading phenomenon, the flaking phenomenon, the improvement of the cleaning property, and the solubility of the polymer in the solvent, and the unit having the average polymerization number of c is the styling product. Gives solubility in water when washing hair after use. When the average polymerization number includes only one of units a and units b, the improvement effects listed above cannot be balanced.

In one example, X ₁ , X ₂ , and X ₃ may be each independently hydrogen or an alkyl group having 1 to 6 carbon atoms.

In one example, R ₁ may be an alkyl group having 4 or more carbon atoms. For example, R ₁ may be an alkyl group having 4 to 20, 6 to 18, 8 to 16 carbon atoms. When the length of the alkyl group, i.e., the carbon number satisfies the above range, an appropriate hydrophilicity / hydrophobicity balance can be realized in the polymer so as to achieve the object of the present application without disturbing the cleanliness.

In one example, A ₁ and A ₂ may be each independently an alkylene group having 1 to 6 carbon atoms. That is, the carbon number of A ₁ and A ₂ may be the same or different from each other.

In one example, A ₁ may be an alkylene group having 1 to 6 carbon atoms. A ₁ in this case greater than the number of carbon atoms, since the hydrophobicity is too strong, the cleaning property is reduced. For example, A ₁ may be an ethylene group or a propylene group. In view of the above effects, an ethylene group may be preferable.

In one example, A ₂ may be an alkylene group having 2 to 6 carbon atoms. When A <_2> exceeds the said carbon number, since hydrophobicity becomes too strong, washability falls. For example, A ₂ may be an ethylene group.

In one example, R ₂ may be hydrogen, or R ₂ may be an alkyl group having 1 to 6 carbon atoms. When R ₂ is hydrogen or an alkyl group having 1 to 6 carbon atoms, the solubility and washability of the polymer in the solvent can be appropriately ensured.

The method for preparing the polymer including the unit of Formula 1 is not particularly limited. For example, when each unit having a polymerization number a, b, and c is referred to as A, B, and C units, the polymer is obtained by copolymerizing monomers (called precursor monomers) capable of providing each unit. Can be. Specifically, the monomer components for preparing the hair setting polymer are as follows.

In one example, an alkyl (meth) acrylate having an alkyl group having 1 to 20 carbon atoms may be used as the precursor monomer of the A unit. For example, methyl (meth) acrylate, ethyl (meth) acrylate, propyl (meth) acrylate, butyl (meth) acrylate, pentyl (meth) acrylate, hexyl (meth) acrylate, 2-ethylhexyl (Meth) acrylate, heptyl (meth) acrylate, octyl (meth) acrylate, nonyl (meth) acrylate, decyl (meth) acrylate, lauryl (meth) acrylate, palmityl (meth) acrylate or Stearyl (meth) acrylates can be used. In addition, two or more of these may be used together.

In one example, an alkyl (meth) acrylate having an alkyl group having 4 to 20 carbon atoms may be used as the precursor monomer of the A unit. When using an alkyl (meth) acrylate having an alkyl group having 4 to 20 carbon atoms, beading and flaking may be improved while having excellent cleaning properties.

In one example, as the precursor monomer of the A unit, an alkyl (meth) acrylate having an alkyl group having 9 to 20 carbon atoms and an alkyl (meth) acrylate having an alkyl group having 1 to 8 carbon atoms may be used together. .

In one example, the precursor monomer of the A unit may be included in 20 parts by weight or more based on 100 parts by weight of the total monomer component for forming the polymer. Specifically, at least 25 parts by weight, at least 30 parts by weight, at least 35 parts by weight, at least 40 parts by weight, at least 45 parts by weight or at least 50 parts by weight may be used. The precursor monomer of the A unit may be used in an amount of 85 parts by weight or less, 80 parts by weight or less, 75 parts by weight or less, 70 parts by weight or less, 65 parts by weight or less, or 60 parts by weight or less. When used in an amount less than the above range, the hydrophilicity of the polymer is so strong that as shown in the following examples, the contact angle to water is lowered, the beading phenomenon is intensified. The beading phenomenon is a phenomenon in which hair spray particles sprayed into the air are not spread evenly on the hair surface but are recognized as round agglomerates. Considering that the hydrophobicity of the hair surface is high, the hydrophobicity of the polymer is considered to be improved. do. In addition, when used in an amount larger than the above range, while the hydrophobicity of the polymer is too strong, the solubility in water is lowered, and thus there is a problem that the product is not washed well with water when used after washing.

The precursor monomer of the B unit is, for example, hydroxy alkyl (meth) acrylates such as 2-hydroxyethyl (meth) acrylate, 2-methoxyethyl (meth) acrylate, 2- (2-hydroxy Ethoxy) ethyl (meth) acrylate, 2- (2-methoxyethoxy) ethyl (meth) acrylate, 2- (2-ethoxyethoxy) ethyl (meth) acrylate, poly (ethylene glycol) mono (Meth) acrylate, poly (ethylene glycol) monoalkylether (meth) acrylate, and the like can be used. In addition, two or more of these may be used together. When using the monomer, it may be advantageous to maintain the hydrophilic / hydrophobic balance of the polymer while maintaining solubility in the solvent. Given this effect, the use of hydroxy alkyl (meth) acrylates may be preferred.

In one example, the precursor monomer of the B unit may be included 5 parts by weight or more based on 100 parts by weight of the total monomer components for forming the polymer. Specifically, 10 parts by weight or more, 15 parts by weight or more, 20 parts by weight or more, 25 parts by weight or more, 30 parts by weight or more, or 35 parts by weight or more may be used. In addition, the precursor monomer of the B unit may be used in an amount of 65 parts by weight or less, 60 parts by weight or less, 55 parts by weight or less, 50 parts by weight or less, 45 parts by weight or 40 parts by weight or less. When used in an amount less than the above range, since the solubility in the solvent is not sufficient, it is not suitable for, for example, aerosol formulations required for the spray-forming composition, which can intensify the nozzle clogging phenomenon of the hairspray, thereby It is difficult to ensure even applicability to. In addition, when used in an amount larger than the above range, since the contact angle to water is lowered, the beading phenomenon may be intensified on the hair surface.

In one example, a compound providing the X ⁺ and / or Y ⁻ may be used to form a C unit through a predetermined process. For example, as the precursor monomer of the C unit, a material capable of providing a metal salt or a quaternary ammonium salt of (meth) acrylate to the polymer after a predetermined reaction may be used. More specifically, tertiary amines and alkyl halides may be used for C unit formation, and quaternary ammonium salts may be generated as X ⁺ and halides may be generated as Y ⁻ by the reaction thereof. Although not particularly limited, 2- (N, N-dimethylamino) ethyl (meth) acrylate may be used as the tertiary amine, and benzyl chloride may be used as the alkyl halide.

In another example, the C unit is itself a copolymerizable monomer having a quaternary ammonium salt functional group (e.g. (meth) acrylate monomer having a quaternary ammonium salt group) and the A unit precursor monomer and B unit precursor monomer It can be obtained by copolymerization.

In one example, the precursor monomer of the C unit may be included 5 parts by weight or more based on 100 parts by weight of the total monomer components for forming the polymer. Specifically, 10 parts by weight or more, 15 parts by weight or more, 20 parts by weight or more, 25 parts by weight or more, or 30 parts by weight or more may be used. The precursor monomer of the C unit may be used in an amount of 70 parts by weight or less, 60 parts by weight or less, 50 parts by weight or less, or 40 parts by weight or less. If the above range is exceeded, solubility in solvents or gases is low, so that the preparation of the aerosol formulation is difficult. If the range is below the above range, sufficient cleanability cannot be provided.

In one example, tertiary amines such as 2- (N, N-dimethylamino) ethyl (meth) acrylate as monomers to provide X ⁺ and Y ⁻ , and alkyl halides such as benzyl chloride. When using, exemplary units of Formula 1 may be represented by Formula 2 as follows.

[Formula 2]

In Chemical Formula 2,

X ₁ , X ₂ , and X ₃ are each independently hydrogen or an alkyl group having 1 to 6 carbon atoms,

R ₁ is an alkyl group having 4 to 20 carbon atoms,

A ₁ and A ₂ are each independently an alkylene group having 1 to 6 carbon atoms,

n is an integer from 1 to 50,

R ₂ is hydrogen or an alkyl group having 1 to 6 carbon atoms,

R ₃ , R ₄ , and R ₅ are each independently hydrogen, an alkyl group or a benzyl group,

Y ^- is F ^-, Cl ^-, Br ^-, or I ^-, and

a, b, and c are greater than 0 as the average number of polymerizations of each polymerization unit, and a + b + c has a value between 50 and 1,000.

In one example, the weight average molecular weight (Mw) of the polymer may be in the range of 5,000 to 200,000. For example, the polymer may have a weight average molecular weight of 6,000 or more, 7,000 or more, 8,000 or more, 9,000 or more, 10,000 or more, 11,000 or more, 12,000 or more, 13,000 or more, 14,000 or more, 15,000 or more, 16,000 or more, or 17,000 or more. Further, for example, the polymer may have a weight average molecular weight of 180,000 or less, 150,000 or less, 120,000 or less, 90,000 or less, 60,000 or less, or 30,000 or less. Unless stated otherwise, the weight average molecular weight in the present application may be a conversion value for standard polystyrene measured using a gel permeation chromatograph (GPC).

In one example, the molecular weight distribution (PDI = Mw / Mn, Mw: weight average molecular weight, Mn: number average molecular weight) of the polymer may be in the range of 1.0 to 5.0. For example, the molecular weight distribution may be at least 1.1, at least 1.2, at least 1.3, at least 1.4, or at least 1.5. For example, the molar molecular weight distribution is 4.9 or less, 4.8 or less, 4.7 or less, 4.6 or less, 4.5 or less, 4.4 or less, 4.3 or less, 4.2 or less, 4.1 or less, 4.0 or less, 3.9 or less, 3.8 or less, 3.7 or less, 3.6 Or less, 3.5 or less, 3.4 or less, 3.3 or less, 3.2 or less, 3.1 or less, or 3.0 or less.

In one example, the composition may include a polymer (P1) comprising a unit of Formula 1 in the range of 0.1 to 30 parts by weight based on 100 parts by weight of the total composition.

In one example, the composition may include two or more polymers including the unit of Formula 1. For example, the composition may include a polymer (P11) and a polymer (P12) including units of Formula 1 different from each other, such as R ₁ . In this case, the polymer (P1) including the unit of Formula 1 may be used in the range of 0.1 to 30 parts by weight based on 100 parts by weight of the total composition.

In another example, the composition may include two or more kinds of polymers. For example, the composition may further include a heterogeneous polymer (P2) having a different configuration in addition to the polymer (P1) including the unit of [Formula 1]. The heterogeneous polymer (P2) having a different configuration means a polymer that does not include the unit of [Formula 1].

In one example, the composition is a polyvinylpyrrolidone, a copolymer of polyvinylpyrrolidone / vinylacetate (PVP / VA copolymer), a copolymer of polyvinylpyrrolidone / dimethylaminoethyl methacrylate It may further include a nonionic polymer such as (PVP / dimethylaminoethylmethacrylate copolymer) as the polymer (P2). Alternatively, the composition may be a copolymer of methacryloylethylbetaine / methacrylate (Methacryloylethylbetaine / methacrylate copolymer), and a copolymer of octylacrylamide / acrylate / butylaminoethyl methacrylate (Octylacrylamide / acrylates / butylaminoethylmethacrylatecopolymer) It may further include an amphoteric polymer (P2), such as. In another example, the polymer (P2) listed above may further include two or more polymers.

When the composition includes both the polymer (P1) and the polymer (P2), the weight ratio (P1: P2) of the polymer (P1) and the polymer (P2) may range from 1:99 to 99: 1. In one example, the polymer (P1) may be used in a smaller amount than the polymer (P2), the weight ratio (P1: P2) of the polymer (P1) and the polymer (P2) may be 5: 95 to 30: 70. In another example, the polymer (P1) may be used in excess of the polymer (P2), the weight ratio (P1: P2) of the polymer (P1) and the polymer (P2) may be 95: 5 to 70: 30. . In another example, the polymer (P1) and the polymer (P2) may be used in the same amount. In this case, the total content of the polymer used in the composition may range from 0.1 to 30 parts by weight relative to 100 parts by weight of the total content of the composition.

In one example, the composition comprising the polymer (P1) may satisfy the contact angle of the water droplets on the coating surface formed from the composition, that is, the film to which the composition is applied, 90 to 120 ° range. Specifically, the contact angle can be measured according to the method described in the Examples below. When the contact angle is less than the above range, the coating property of the spray composition may be deteriorated to increase the beading phenomenon, and when the contact angle exceeds the above range, the flaking phenomenon may increase due to the increase of the hard properties of the polymer. In addition, as confirmed in the following examples, the hydrophilic polymer having a low contact angle has a high solubility in water, so that it is dissolved in water and commercialized like a gel or lotion product to absorb moisture in the air when used in hair. Hardness is low. On the other hand, high hydrophobic polymers with high contact angle cannot be used as gel or lotion products because they have low solubility in water, and are dissolved in ethanol or LPG instead of water and commercialized into hairspray. Has the highest hardness Strong hydrophobicity degrades the cleaning power, and excessively high hardness easily causes flaking.

In one example, the composition further comprises a solvent. As the solvent, for example, alcohol such as ethanol or isopropanol may be used. In addition, water may be used. For example, a mixture of water and alcohol may be used as the solvent. When water and alcohol are used in combination, the content of water relative to the total solvent component is preferably 10 parts by weight or less.

In one example, the composition may include a solvent in the range of 100 to 2,000 parts by weight based on 100 parts by weight of the polymer component (P1 and / or P2).

In one example, the composition may be an aerosol spray composition sprayed in the gas phase. That is, the composition may include a high pressure gas propellant capable of injecting an aerosol. The type of propellant is not particularly limited, but may include, for example, one or more of propane, n-butane, isobutane, and dimethyl ether (DME).

In one example, the composition may include a propellant in the range of 100 to 1,500 parts by weight relative to 100 parts by weight of the polymer component (P1 and / or P2).

In one example, the composition may further comprise a plasticizer. The type of plasticizer is not particularly limited, and known plasticizers can be used without limitation, for example, silicone compounds or 2-amino-2-methyl-1-propanol. have.

In one example, the composition may further comprise a moisturizing agent. The type of moisturizer is also not particularly limited, and for example, a known material such as propylene glycol can be used without limitation.

In addition, the composition may further comprise additives (pH modifiers, fragrances, sunscreens) that can provide moisturizing, conditioning and / or fragrance to the hair.

According to an example of the present application, a hair styling composition having excellent style holding power of a set hair, but less beading or flaking may be provided. In addition, the compositions can provide excellent detergency even after use of hair styling products.

Hereinafter, the present application will be described in detail through examples. However, the scope of protection of the present application is not limited by the embodiments described below.

<Measurement method>

* Measurement of contact angle

Contact angle was measured using a contact angle measuring instrument (Attension Theta Lite, Biolin Scientific). Specifically, 1 g of each composition blended as shown in Table 1 was coated with a uniform thickness (120 μm) on an acrylic plate having a width of 6 cm, a length of 4 cm, and a height of 0.3 cm. Immediately after dropping 4 mg droplets on the coating surface, the contact angle between the coating surface and the droplets was measured at an interval of 1 second for 1 minute, and the average value was obtained. The above calculation was repeated three times with different coating surface positions, and the average value was obtained. The contact angle refers to the angle between the tangent and the solid surface of the liquid at the three phases of the solid (polymer coating surface), liquid (water droplets), and gas (air) phases. The characteristics of the polymer coating surface were determined as follows according to the contact angle. The results are shown in Table 2.

-Less than 50 °: hydrophilic, weak hardness, strong solubility in water

-Above 50 and below 90 °: weak hydrophobic, moderate hardness, moderate solubility in water

-More than 90 and less than 120 °: hydrophobic, high hardness, not solubility in water

-120 ° and above: strong hydrophobicity, very high hardness, not suitable for use in hair products

Flaking Assessment

200 evaluators who actually used the hair spray product were allowed to use the hair spray composition blended in the examples and the comparative examples. Sensory tests were performed. Specifically, the average score of each Example and Comparative Example was evaluated by evaluating the case where flaking is not visually recognized on the hair as 10 points and the case where the flaking was excessively visualized by 1 point. The record was made. The results are shown in Table 2.

-7-10 points (good): no flaking

-4-6 points (usually): Flaking occurs but is weak

-1-3 points (bad): Flaking occurs badly
