[Effects of the Invention]

[0006] According to the present invention, a stable, transparent, gel-like hair styling composition for eyebrows can be provided. [Modes for carrying out the invention]

[0007] The present invention will be described in detail below. In this specification, unless otherwise specified, the notation "a~b" for numerical values ​​a and b is equivalent to "a or more and b or less". That is, the notation "a~b" includes the numerical values ​​a and b at both ends. If a unit is attached only to numerical value b in such notation, that unit shall also apply to numerical value a.

[0008] 《Film-forming polymer; component A》 The eyebrow styling composition of the present invention contains one or more film-forming polymers, including an acrylic polymer containing alkylacrylamide and / or diacetoneacrylamide as essential monomer components. The film-forming polymer is a polymer that forms a film on the surface of the eyebrows and exhibits the effect of further improving the setting power. Component A is a polymer containing structural units derived from alkylacrylamide and / or diacetoneacrylamide. In the present invention, component A may be in the form of a salt of an acrylic polymer containing alkylacrylamide and / or diacetoneacrylamide as an essential monomer component, such as a sodium salt (hereinafter abbreviated as Na), an ammonium salt, a triethanolamine salt, a 2-amino-2-methyl-1-propanol salt (hereinafter sometimes referred to as AMP), or a 2-amino-2-methyl-1,3-propanediol salt (hereinafter sometimes referred to as AMPD).

[0009] Examples of component A include (alkyl acrylate / diacetone acrylamide) copolymer [INCI name: Acrylates / Diacetone Acrylamide Copolymer], (acrylates / alkyl acrylate (C1-18) / alkyl (C1-8) acrylamide) copolymer AMP [INCI name: AMP-Acrylates / C1-18 Alkyl Acrylate / C1-8 Alkyl Acrylamide Copolymer], and (alkyl acrylate / diacetone acrylamide) copolymer AMP [INCI name: AMP-Acrylates / Diacetone Acrylamide Copolymer].

[0010] Component A can also be a commercially available product. Examples of commercially available (acrylates / alkyl(C1-18) acrylate / alkyl(C1-8) acrylamide) copolymer AMP include the product names "Plus Size L-9909B", "Plus Size L-9716U", and "Plus Size L-9900". Examples of commercially available (alkyl acrylate / diacetone acrylamide) copolymer AMP include the product names "Plus Size L-6330" and "Plus Size L-6466". Please note that "Plus Size" is a registered trademark.

[0011] The content of component A in the total composition is not particularly limited as long as the effects of the present invention are obtained, but from the viewpoint of forming a film on the eyebrow surface and providing setting power, it can be 0.1 to 30% by weight, 1 to 20% by weight, 2 to 18% by weight, 3 to 15% by weight, 4 to 12% by weight, or 5 to 10% by weight.

[0012] Hydrophobized acrylic thickener; component B The eyebrow styling composition of the present invention contains one or more hydrophobic acrylic thickeners. An acrylic thickener is a thickener that contains acrylic acid as a constituent unit. A hydrophobic acrylic thickener means an acrylic thickener in which some or all of its constituent units are modified with hydrocarbon groups or ethylene oxide, thereby making it hydrophobic.

[0013] The hydrophobized acrylic thickener that can be used in the present invention is preferably an acrylic copolymer that has been hydrophobized with ethylene oxide in an average number of moles added of 5 to 60 moles. More preferably, the ethylene oxide, in an average number of moles added of 5 to 60 moles, is added to the hydroxyl groups of each alcohol contained in the structure of the acrylic thickener. The average number of moles added of ethylene oxide can be, for example, 5 to 60, 5 to 50, 5 to 40, 8 to 35, 10 to 30, 12 to 28, or 15 to 25.

[0014] Examples of Component B include the following: · (Acrylates / Palmeth-25 Acrylate Copolymer) [INCI name: Acrylates / Palmeth-25 Acrylate Copolymer] · (Acrylates / Steareth-20 Methacrylate Copolymer) [INCI name: Acrylates / Steareth-20 Methacrylate Copolymer] · (Acrylates / Beheneth-25 Methacrylate Copolymer) [INCI name: Acrylates / Beheneth-25 Methacrylate Copolymer] · (Acrylates / Steareth-20 Itaconate Copolymer) [INCI name: Acrylates / Steareth-20 Itaconate Copolymer] · (Acrylates / Itaconic Acid Ceteth-20 Copolymer) [INCI name: Acrylates / Itaconic Acid Ceteth-20 Copolymer] · (Acrylates / Steareth-20 Methacrylate Copolymer) [INCI name: Acrylates / Steareth-20 Methacrylate Copolymer] · (Acrylates / Steareth-50 Acrylate Copolymer) [INCI name: Acrylates / Steareth-50 Acrylate Copolymer] · (Acrylates / Itaconic Acid Palmeth-25 Copolymer) [INCI name: Acrylates / Itaconic Acid Palmeth-25 Copolymer] · (Acrylates / C10-30 Alkyl Acrylate Crosspolymer) [INCI name: Acrylates / C10-30 Alkyl Acrylate Crosspolymer].

[0015] Component B can also be a commercially available product. Examples of commercially available (acrylates / palmes-25 acrylate) copolymers include the trade name "Rheostyl E-Cream". Examples of commercially available (acrylates / steareth-20 methacrylate) copolymers include the trade names "ACULYN 22" and "ACULYN 88". Examples of commercially available (acrylates / steareth-20 itaconic acid) copolymers include the trade name "Structure 2001", etc. Examples of commercially available (acrylates / beheneth-25 methacrylate) copolymers include the trade name "Rheostyl 90N", etc. Examples of commercially available (acrylates / ceteth-20 itaconic acid) copolymers include the trade name "Structure 3001", etc. Examples of commercially available (acrylates / alkyl acrylate (C10-30)) crosspolymers include the trade names "Carbopol Ultrez21 Polymer" and "Carbopol ETD2020 Polymer". Rheostyl, ACULYN, Structure, and Carbopol are registered trademarks.

[0016] The content of component B on a basis of the total composition is not particularly limited as long as the effects of the present invention are obtained, but it can be 0.01 to 20% by weight, 0.05 to 18% by weight, 0.1 to 15% by weight, 0.2 to 12% by weight, 0.3 to 10% by weight, or 0.5 to 6% by weight. The ratio of the content of component B to the content of component A on a total composition basis (content of component B / content of component A) is not limited to the following, but can be, for example, 0.02 to 2, 0.05 to 1, 0.1 to 0.8, or 0.1 to 0.5.

[0017] The inventors attempted to create a gel-like substance by adding various acrylic thickeners to an eyebrow styling composition containing component A. They discovered that only hydrophobic acrylic thickeners could form a gel while maintaining transparency and stability. In other words, using non-hydrophobic acrylic thickeners failed to maintain at least one of transparency or stability. Furthermore, with non-hydrophobized acrylic thickeners, transparency deteriorated as viscosity increased. On the other hand, when the amount of hydrophobized acrylic thickener added was varied to change the viscosity, transparency and stability were maintained at all viscosities. This is surprising. Therefore, the eyebrow styling composition of the present invention makes it possible to provide eyebrow styling compositions of various viscosities depending on the desired product characteristics and applications.

[0018] 《Water; Component C》 The eyebrow styling composition of the present invention contains water. The content of component C on a basis of the total composition is not particularly limited as long as the effects of the present invention are obtained, but it can be 50-99% by weight, 55-95% by weight, 60-90% by weight, 65-85% by weight, or 65-80% by weight.

[0019] Nonionic surfactant; component D The eyebrow styling composition of the present invention may further contain a nonionic surfactant. The nonionic surfactant may be added to improve workability. Examples of nonionic surfactants include sorbitan fatty acid esters, glycerin fatty acid esters and their alkylene oxide adducts, polyoxyalkylene alkyl ethers, polyoxyethylene alkyl ethers, polyoxyalkylene fatty acid esters, polyoxyalkylene alkylphenols, polyoxyethylene fatty acid esters, polyoxyethylene alkylphenyl formaldehyde condensates, polyoxyethylene sterols and their derivatives, polyoxyethylene lanolin and its derivatives, polyoxyethylene beeswax derivatives, sugar esters, polyoxyethylene hydrogenated castor oil, polyglycerin-modified silicones, and polyoxyethylene castor oil. The content of component D on a basis of the total composition is not particularly limited as long as the effects of the present invention are obtained, but it can be 0.01 to 5% by weight, 0.05 to 3% by weight, or 0.1 to 2% by weight.

[0020] Ethanol; ingredient E The eyebrow styling composition of the present invention may further contain ethanol. The inclusion of ethanol can enhance the quick-drying properties of the eyebrow styling composition of the present invention. The content of component E on a basis of the total composition is not particularly limited as long as the effects of the present invention are obtained, but it can be 1-40% by weight, 2-30% by weight, 3-25% by weight, 5-20% by weight, or 10-20% by weight.

[0021] 《Inorganic powder》 The eyebrow styling composition of the present invention preferably does not contain inorganic powder. The inclusion of inorganic powder may result in a loss of transparency. Furthermore, the inclusion of inorganic powder may cause flaking. The eyebrow styling composition of the present invention may contain inorganic powder, but it is preferable that it contains it within a range that maintains the transparency, gel-like form, and stability of the present invention. Specifically, the eyebrow styling composition of the present invention may contain inorganic powder in amounts of 2% by weight or less, 1% by weight or less, 0.5% by weight or less, 0.1% by weight or less, or 0.01% by weight or less, based on the total amount of the composition.

[0022] Examples of inorganic powders used in this invention include mica, talc, kaolin, sericite, phlogopite, iron oxide, black iron oxide, yellow iron oxide, red iron oxide, titanium dioxide, zinc oxide, iron titanate, aluminum hydroxide, aluminum oxide, hectorite, bentonite, smectite, montmorillonite, vermiculite, magnesium carbonate, calcium carbonate, amorphous silica, spherical silica, diatomaceous earth, magnesium silicate, calcium silicate, aluminum silicate, barium silicate, strontium silicate, sodium silicate, barium sulfate, metal tungstate, anhydrous silicic acid, hydroxyapatite, zeolite, boron nitride, manganese violet, cobalt violet, chromium oxide, chromium hydroxide, cobalt titanate, ultramarine, cone, aluminum powder, copper powder, and synthetic fluorophlogopite.

[0023] The eyebrow styling composition of the present invention may contain components other than components A to E, as long as they do not hinder the effects of the present invention. Each of the components other than components A to E may be used individually or in combination of two or more. Ingredients other than components A to E include preservatives (e.g., phenoxyethanol, methylparaben, ethylparaben); pH adjusters (lactic acid, sodium lactate, citric acid, sodium citrate, triethanolamine, AMP, etc.); polyhydric alcohols (ethylene glycol, propylene glycol, dipropylene glycol, polyethylene glycol, 1,3-butylene glycol, etc.); lower alcohols other than component E; surfactants other than component D; antioxidants; plant extracts; and fragrances.

[0024] Gel-like In this specification, an eyebrow styling composition is described as "gel-like" specifically when its viscosity is between 30 mPa·s and 40,000 mPa·s, 40 mPa·s and 30,000 mPa·s, 50 mPa·s and 28,000 mPa·s, 80 mPa·s and 25,000 mPa·s, or 100 mPa·s and 20,000 mPa·s. The upper limit may be 18,000 mPa·s, 15,000 mPa·s, 13,000 mPa·s, 10,000 mPa·s, or 8,000 mPa·s.

[0025] The method for measuring viscosity is as follows: ·Measurement method 200g of the sample to be measured is placed in a glass container measuring 62mm in diameter and 110mm in height, sealed, and stored at 25°C for 24 hours. After that, it is stirred at 500 rpm for 5 minutes with a 30mm diameter stirring blade, and then measured at 25°C using a B-type viscometer. • Viscometer manufacturer: Toki Sangyo Co., Ltd. ·Device name: VISCOMETER TV-35 • Rotor number: 2, 3, or 4 (depending on viscosity) • Rotation speed: 30 rpm • Rotation time: 5 minutes

[0026] In this specification, "transparent" in a hair styling composition for eyebrows means that it is not opaque but transparent. Whether or not a composition is transparent can be determined, for example, by placing the hair styling composition for eyebrows of the present invention in a glass bottle and seeing through the bottle to the other side. "Transparent" simply means that it is transparent, and does not require the presence or absence of color (e.g., red, purple, blue, light blue, yellow, etc.), but it is preferable that it has no color.

[0027] Eyebrow styling composition The eyebrow styling composition of the present invention is a cosmetic product used for styling and grooming eyebrows. The eyebrow styling composition of the present invention is preferably an eyebrow gel or eyebrow mascara, and more preferably an eyebrow gel. If the eyebrow styling composition of the present invention is an eyebrow mascara, it is preferably a transparent eyebrow mascara. The eyebrow styling composition of the present invention can be filled into any suitable container, such as a plastic bottle, glass bottle, or pouch. The container may be integrated with a brush, comb, coil, or the like. [Examples]

[0028] The present invention will be specifically described below with reference to examples, but these examples are not intended to limit the scope of the invention. Unless otherwise specified, % refers to weight %.

[0029] In the following examples, eyebrow styling compositions were prepared with the component compositions shown in Table 1. Components A, B, and D were sourced from the following raw materials. Viscosity was measured as described above, in units of mPa·s. ·Raw materials used (Component A) • (Alkyl acrylate / diacetone acrylamide) copolymer AMP (Product name: Plus Size L-6330U) (Component B) • (Acrylates / Palmes-25 Acrylate) Copolymer (Product Name: Rheostyl E-Cream) • (Acrylates / Steareth-20 Methacrylate) Copolymer (Product Name: ACULYN 22) • (Acrylates / Beheneth-25 Methacrylate) Copolymer (Trade name: Rheostyl 90N) (Component D) • PEG-60 Hydrogenated Castor Oil (Product Name: NIKKOL HCO-60) • PEG-40 stearate (product name NIKKOL MYS-40V) • Behenes-30 (Product name: NIKKOL BB-30) Polyglyceryl-3 disiloxane dimethicone (product name KF-6100)

[0030] Each evaluation item was assessed as follows: ○ indicates that the product is usable, and △ and × indicate that the product is unusable. Transparency: The appearance and color of the cosmetic product were visually observed and evaluated according to the following criteria. ○: It was almost transparent. △: It was semi-transparent. ×: It was unclear. • Stability: The cosmetic product was filled into a sample tube, its appearance was visually observed, and the stability of the formulation was evaluated according to the following criteria. ○: Even at high temperatures (50°C), there was no change in appearance, demonstrating excellent stability. △: At room temperature (25℃), there was no change in appearance, indicating excellent stability. ×: Layer separation and aggregation were observed.

[0031] [Table 1]

[0032] Examples 1-3, which contained all of components A-C, showed good transparency and stability. Furthermore, Examples 1-3 exhibited increased viscosity and formed a gel. Comparative Example 1, which did not contain component B, had low viscosity and did not form a gel. Comparative Examples 2-3, which contained non-hydrophobized acrylic thickeners (containing Acrylates Copolymer 1 (trade name Rheostyl 100) or Acrylates Copolymer 2 (Rheostyl E-Light)), showed deterioration in at least one of transparency and stability. Therefore, it was found that combining a hydrophobic acrylic thickener with a film-forming polymer containing an acrylic polymer that includes alkylacrylamide and / or diacetoneacrylamide as essential monomer components results in a gel-type eyebrow styling composition that exhibits good transparency and stability.

[0033] In the following examples, a gel-type eyebrow styling composition was prepared by increasing the amount of component B added, using the component composition shown in Table 2.

[0034] [Table 2]

[0035] Examples 4-6, which contained all components A-C, showed good transparency and stability. Furthermore, Examples 4-6 maintained their transparency even when the viscosity was increased compared to Examples 1-3. Comparative Example 4, which contained acrylates copolymer 1, showed deterioration in both transparency and stability. Transparency was even worse compared to Comparative Example 2, which contained a smaller amount of acrylates copolymer 1. Comparative Example 5, which contained acrylates copolymer 2, showed a deterioration in transparency. Therefore, it was found that even when the amount of component B added was increased to further raise the viscosity, the gel-type eyebrow styling composition exhibited good transparency and stability.

[0036] In the following examples, a gel-type eyebrow styling composition was prepared by further increasing the amount of component B added, using the component composition shown in Table 3.

[0037] [Table 3]

[0038] Examples 7-9, which contained all components A-C, showed good transparency and stability. Furthermore, Examples 7-9 maintained their transparency even when the viscosity was further increased compared to Examples 4-6. Comparative Example 6, which contained acrylates copolymer 1, showed deterioration in both transparency and stability. Transparency was even worse compared to Comparative Example 2, which contained a smaller amount of acrylates copolymer 1. Comparative Example 7, which contained acrylates copolymer 2, showed a deterioration in transparency. Therefore, it was found that even when the amount of component B added was further increased to further raise the viscosity, the gel-type eyebrow styling composition exhibited good transparency and stability.

[0039] In the following examples, gel-type eyebrow styling compositions were prepared by adding various nonionic surfactants with the component compositions shown in Tables 4 and 5.

[0040] [Table 4]

[0041] [Table 5]

[0042] Even when the type of component D was changed, Examples 10-21 showed good transparency and stability. Furthermore, Examples 10-21 formed gels. [Industrial applicability]
