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 not sticky, 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) describes 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, and that the composition 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 a mist-like powder cosmetic which is blended with respective specific amounts of a polymer compound for hair fixation, a polyhydric alcohol, a monohydric alcohol, and a spray, and which is excellent in 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 ability (setting ability, finishing ability) cannot be obtained and that hair washing ability is insufficient.

Jp-a-3-261713 (patent document 3) discloses a hair cosmetic composition containing a specific polyoxyalkylene compound and/or polyoxyalkylene alkyl glycoside, a polymer compound for hair fixation, and a high molecular weight polyethylene glycol (molecular weight 6,000 to 30,000), which has hair-setting properties and smoothness (smooth feel). However, the hair cosmetic of patent document 3 has a problem that sufficient hair setting power (setting power, finishing power) cannot be obtained.

Japanese patent laid-open publication No. 2002-167317 (patent document 4) describes a hair cosmetic composition containing an amphoteric polymer, a sugar alcohol, and a sugar alcohol derivative (e.g., a polyoxyalkylene adduct of a sugar alcohol), which has hair styling properties, hair style retention properties, and no sticky or hard feeling. However, the hair cosmetic of patent document 4 has a problem that sufficient finishing power cannot be obtained and that the hair-washing property is insufficient.

In aqueous hair styling cosmetics having a low viscosity, it is difficult to achieve both hair styling power (styling power, finishing power) and hair restyling power, and it is particularly difficult to achieve both styling retention power. Therefore, development of an aqueous low-viscosity hair styling cosmetic which has a sufficient hair styling ability, a sufficient hair restyling ability, and a sufficient styling retention ability and which has 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 entire power. 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, in particular, when the hair conditioner is used in the form of mist by spraying, the hair conditioner components may be attached to the eyes and scalp. Further, anionic surfactants and cationic surfactants are not preferable because they tend to foam 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. Further, the volatilization of the solvent component or the like tends to be slower than that of the nonionic surfactant, and the hair styling effect tends to be slower.

Cationic surfactants are not preferable from the viewpoint that they have high hair affinity, and therefore they soften hair and make it difficult to exert hair styling power.

Examples of the nonionic surfactant used in the present invention include those which are solid at ordinary temperature among the nonionic surfactants exemplified below.

In particular, when the hair styling cosmetic of the present invention is used in the form of a hair spray or hair spray, it is preferably used by spraying, and 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 (d) 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 degree of polymerization of the copolymer to be blended, increasing or decreasing the amount of a polymer or the like to be added, and adjusting the amount of an aqueous solvent to be blended.

Conventionally, it has been difficult to obtain both sufficient hair styling power and sufficient hair restyling power, and it has been difficult to achieve both sufficient hair styling power and sufficient hair restyling power, particularly to achieve a further hair styling retention power. The hair styling cosmetic of the present invention has a low viscosity, but successfully combines sufficient hair styling power, hair restyling power, and setting retention power.

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, 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).
