Description

Hair styling cosmetic

Technical Field

The present invention relates to a hair styling cosmetic. More specifically, the present invention relates to a hair styling cosmetic which has a low viscosity, but is excellent in hair styling performance, hair restyling performance, and hair style retention, and is free from stickiness, smooth, and excellent in light feeling after hair styling.

Background

Conventionally, hair styling cosmetics contain hair styling resins such as hair-fixing polymers and film-forming polymers for styling purposes. However, the hair setting resin may have disadvantages such as hardening, unevenness of the coating film, and reduction in the mold holding force under high humidity. Therefore, various countermeasures are taken to solve the problem.

For example, Japanese patent application laid-open No. 2004-505902 (patent document 1) discloses that a hair care composition containing a specific water-soluble polyalkylene glycol and a film-forming polymer in a specific ratio and further containing a liquid carrier is excellent in removability and touch. However, the hair care composition of patent document 1 has a problem that sufficient hair setting power (setting power, finishing power) cannot be obtained.

Jp 2007-217314 a (patent document 2) describes that a mist-like powder cosmetic containing specific amounts of a polymer compound for hair fixation, a polyhydric alcohol, a monohydric alcohol, and a spray agent is excellent in hair restorability, free from sticky feeling, and has natural luster. However, the mist-like powder cosmetic of patent document 2 has a problem that sufficient hair styling power (setting power, finishing power) cannot be obtained and that hair washing performance is insufficient.

In the case of an aqueous hair styling cosmetic having a low viscosity, it is difficult to achieve both hair styling performance (setting performance, finishing performance) and hair restyling performance, and it is particularly difficult to impart a setting retention performance to the cosmetic at the same time. Therefore, development of an aqueous low-viscosity hair styling cosmetic having a satisfactory hair styling ability, hair restyling ability, and hair style retention ability and having a good feeling in use has been demanded.

Detailed Description

The present invention will be described in detail below. Hereinafter, POE represents polyoxyethylene, POP represents polyoxypropylene, and POB represents polyoxybutylene.

[ (a) component ]

(a) The component is a surfactant which is solid (solid) at normal temperature (25 ℃). In the present invention, it has been found that a solid surfactant exerts an effect of improving the grip strength. When a surfactant which is liquid at ordinary temperature is used instead of the component (a), sufficient hair styling power and styling retention power cannot be obtained, and the effects of the present invention cannot be exhibited. Examples of the solid surfactant used in the present invention include anionic surfactants, cationic surfactants, amphoteric surfactants, and nonionic surfactants. Nonionic surfactants are preferably used in the present invention. The reason for this is as follows.

Anionic surfactants and cationic surfactants are more irritating to the skin than nonionic surfactants, and are not preferable because the hair styling components may be attached to the eyes and scalp when the hair styling components are used in the form of mist during use. Further, anionic surfactants and cationic surfactants are not preferable from the viewpoint that foaming is likely to occur during hair styling.

When an anionic surfactant, a cationic surfactant, or an amphoteric surfactant is used, precipitation may occur due to a combination of other ionic complexing components. In addition, the volatilization of the solvent component and the like tends to be slower and the hair styling effect tends to be slower than those of the nonionic surfactant.

The cationic surfactant is not preferable from the viewpoint that the cationic surfactant is not preferable because it is not only as described above but also because it has high hair-affinity, and therefore, it softens the hair and makes it difficult to exert hair-styling power.

Among the nonionic surfactants exemplified below, the nonionic surfactant that is solid at ordinary temperature can be exemplified as the nonionic surfactant that can be used in the present invention.

9. Polyoxyethylene polyoxypropylene decyl tetradecyl ether:

examples of the commercially available products include "ユニル - ブ 50 MT-2200B" (manufactured by Nichiku Kogyo Co., Ltd.).

(a) As the component (B), a solid (solid state) at ordinary temperature (25 ℃ C.) was used. By using a solid (solid) substance as the component (a), a hair styling power, a styling retention power, and the like can be effectively imparted. In addition, the hair-washing property is also improved.

In the present invention, the hardness is preferably 20 or more, and particularly preferably 40 or more, as a standard indicating the solid (solid) state of the component (a). Here, the term "hardness" means that a molten sample is first poured into a cylindrical glass bottle having a diameter of 3cm and a depth of 3cm (a depth of 1cm or more), and acclimatized at 25 ℃ for 12 hours or more.

(wherein MW represents the molecular weight of the hydrophilic moiety and MO represents the molecular weight of the lipophilic moiety)

(a) The amount of the component (b) is 1.5 to 12% by mass, preferably 2 to 10% by mass, and more preferably 2.5 to 10% by mass in the hair styling cosmetic of the present invention. When the amount is less than 1.5% by mass, it is difficult to obtain a sufficient effect by the component (a), while when the amount is more than 12% by mass, not only an increase in the effect according to the amount to be blended is not observed, but also a tendency to increase the viscosity is observed, which is not preferable in terms of stickiness, a heavy feeling after hair styling, and the like.

[ (b) component ]

As the polyalkylene glycol polymer which is liquid at room temperature (25 ℃ C.), preferred examples thereof include EO polymers obtained by polymerizing EO structural units, PO polymers obtained by polymerizing PO structural units, BO polymers obtained by polymerizing BO structural units, and copolymers obtained by copolymerizing the above structural units. Particularly preferred are EO polymers, EO/PO copolymers containing EO structural units and PO structural units, EO/BO copolymers containing EO structural units and BO structural units, and the like. The copolymerization form is not particularly limited, and may be any form such as block copolymerization, graft copolymerization, random copolymerization, or the like.

Specifically, PEG200, PEG300, PEG400, PEG600, and the like can be exemplified.

As a specific example of the EO/PO copolymer, for example, a random copolymer represented by the following formula (X) is preferably used.

In the formula (X), R₁、R₂Each independently represents an alkyl group having 1 to 4 carbon atoms or a hydrogen atom. Examples of the alkyl group having 1 to 4 carbon atoms include a methyl group, an ethyl group, an n-propyl group, an isopropyl group, an n-butyl group, a sec-butyl group, and a tert-butyl group. Methyl and ethyl are preferred. When the alkyl group has 5 or more carbon atoms, the hydrophilicity tends to decrease, and the moisturizing feeling tends to decrease.

The ratio of p (the number of addition moles of EO structural units) to q (the number of addition moles of PO structural units) is 10 to 0.5, preferably 5 to 0.8. In addition, p + q is more than or equal to 2 and less than or equal to 100.

Specific examples of the copolymer represented by the formula (X) include POE (9)/POP (2) random copolymer dimethyl ether, POE (14)/POP (7) random copolymer dimethyl ether, POE (36)/POP (41) random copolymer dimethyl ether, POE (55)/POP (28) random copolymer dimethyl ether and the like.

The lower limit of the molecular weight is not particularly limited, but is preferably about 200 or more, and particularly preferably about 300 or more. Specifically, PPG700, PPG1,000, PPG1,200, and the like can be exemplified.

In the hair styling cosmetic of the present invention, the component (b) is mainly useful for restyling, and is free from stickiness, smoothness and the like.

(b) The amount of the component (b) is preferably 0.1 to 30% by mass, more preferably 2 to 15% by mass, and particularly preferably 2 to 10% by mass in the hair styling cosmetic of the present invention. When the amount is less than 0.1% by mass, it is difficult to obtain a sufficient effect by the component (b), while when the amount is more than 30% by mass, not only an increase in the effect according to the amount to be blended is not observed, but also a tendency to increase the viscosity is observed, which is not preferable in terms of stickiness, a heavy feeling after hair styling, and the like.

In the hair styling cosmetic of the present invention, the component (c) mainly contributes to the setting power, the restyling power, the light feeling after styling, and the like. (c) The components can be 1 or more than 2.

(c) The amount of the component (b) is preferably 0.1 to 15% by mass, more preferably 2 to 6% by mass, in the hair styling cosmetic of the present invention. If the amount is less than 0.1% by mass, it is difficult to obtain a sufficient effect by the component (c), while if it exceeds 15% by mass, not only the effect is not increased in accordance with the amount to be blended, but also the viscosity tends to be high, which causes hardening, and is not preferable.

The hair-setting cosmetic composition of the present invention contains the above-mentioned components (a) to (c) as essential components. The present invention preferably contains substantially no oil (except for the fragrance and phenoxyethanol). By not containing an oil component, a reduction in a sticky feeling can be effectively obtained, and by not emulsifying, the appearance can be adjusted to be transparent. In the present invention, a sufficient smooth feeling can be obtained even if oil is not contained.

The hair styling cosmetic of the present invention has a system viscosity of 10,000 mPas (25 ℃ C., B-type viscometer) or less, preferably 1,000 mPas or less. In particular, when the hair styling cosmetic of the present invention is used by spraying in the form of a hair spray or hair spray, the viscosity is preferably 100mPa · s or less. The lower limit of the viscosity is not particularly limited, but is preferably about 8mPa · s or more from the viewpoint of usability and the like.

The hair styling cosmetic of the present invention is obtained by dissolving components (a) to (c) and any other additive components in an aqueous solvent [ for example, an alcoholic solvent such as water or a 1-membered lower alcohol having 1 to 6 carbon atoms (for example, ethanol or isopropyl alcohol), or a mixed solvent thereof). The hair styling cosmetic of the present invention is aqueous and has a low viscosity, and the viscosity can be adjusted by, for example, controlling the polymerization degree of the copolymer to be blended, increasing or decreasing the amount of a polymer or the like to be added, and adjusting the blending amount of an aqueous solvent.

Conventionally, it has been difficult to obtain both sufficient hair styling power and sufficient hair restyling power, and it has been difficult to provide both styling retention power and hair restyling power in an aqueous low-viscosity hair styling cosmetic. The hair styling cosmetic of the present invention has a low viscosity, but successfully has a sufficient hair styling power, hair restyling power, and setting retention.

In the hair styling cosmetic of the present invention, other components used in usual cosmetics, medicines and the like may be optionally added in addition to the above components within a range not impairing the effect of the present invention. Examples of such ingredients include powder ingredients, higher fatty acids, ultraviolet absorbers, polyols, metal ion chelating agents, sugars, amino acids, organic amines, polymer emulsions, pH adjusters, skin nutrients, vitamins, antioxidants, antioxidant aids, perfumes, and the like, and these ingredients may be appropriately blended as necessary to produce the hair styling cosmetic of the present invention by a conventional method according to the intended formulation.

The hair styling cosmetic of the present invention may be either an aqueous type or a solubilized type. Preferred embodiments of the hair styling cosmetic of the present invention include aerosol hair sprays, non-aerosol hair sprays, hair mousses, hair fixative solutions, hair styling gels, hair styling liquids, and the like.

The hair styling cosmetic of the present invention is aqueous and has a low viscosity, and therefore, even in the form of a spray for use such as a hair spray or hair spray, the hair styling cosmetic can be stably sprayed in a mist form without clogging the spray nozzle of the spray container, has excellent hair styling properties and hair restyling properties, and can be widely and uniformly applied to hair. In addition, in the case of a hair styling cosmetic of an aerosol type, it is common to fill a spray container with a spray. As the spray agent, any known spray agent in the field of aerosols such as liquefied gases such as propane, butane, pentane, and dimethyl ether, and compressed gases such as nitrogen and compressed air can be used. The amount of these sprays is preferably about 5 to 200 mass% relative to 100 mass% of the hair styling cosmetic (stock solution).
