Description

Hairdressing cosmetics

The present invention relates to a hairdressing cosmetic. More particularly, the present invention relates to a hair styling cosmetic composition that has excellent hair styling ability and re-styling ability while having low viscosity, is non-sticky, is smooth, and is excellent in lightness of finish.

Conventionally, in hairdressing cosmetics, hairstyling resins such as hair fixing polymers and film-forming polymers are blended for styling. However, hair-styling resins have problems such as stiffening, non-uniformity of the film, and a decrease in styling holding power under high humidity. Therefore, various countermeasures have been taken in order to solve this problem.

For example, in Japanese Patent Application Laid-Open No. 2007-217314 (Patent Document 1), a mist-like powder cosmetic containing a specific amount of a hair fixing polymer compound, a polyhydric alcohol, a monohydric alcohol, and a propellant has been described. It is described that it has excellent properties, has no stickiness, and has a natural gloss.

In Japanese Patent Application Laid-Open No. 11-10032 (Patent Document 2), a hair cosmetic containing a specific amount of a specific low-viscosity polyether compound and a high-molecular resin compound has hair styling power and hair styling keeping power, and is sticky. In addition, it is described that the hair can be re-styled with a handbrush or the like even after drying, without being stiff.

JP-A-3-261713 (Patent Document 3) discloses a specific polyoxyalkylene compound and / or polyoxyalkylene alkylglycoside, a polymer compound for fixing hair, and a high molecular weight polyethylene glycol (molecular weight 6,000). It is described that a hair cosmetic containing ˜30,000) has hair styling properties and smoothness (smoothness).

JP 2002-167317 A (Patent Document 4) discloses a hair cosmetic composition containing an amphoteric polymer, a sugar alcohol, and a sugar alcohol derivative (for example, a polyoxyalkylene adduct of a sugar alcohol). It describes that it has a set holding power and does not have a sticky or stiff feeling.

In JP-T-2004-505902 (Patent Document 5), a hair composition containing a specific water-soluble polyalkylene glycol and a film-forming polymer in a specific ratio and further containing a liquid carrier has a re-styling property and feel. It is described that it is excellent.

However, in the above publication, particularly in low-viscosity cosmetics, the hair styling power and the re-hair styling power are obtained to a level that can be fully satisfied, and in addition, there is no stickiness, smoothness and finish. There is no description or suggestion about the purpose or problem of obtaining a hairdressing cosmetic that exhibits the effect of being light. In hairdressing cosmetics with low viscosity, it is particularly difficult to achieve both setting power and arranging power. Therefore, development of a low-viscosity cosmetic for hairdressing that has both sufficient setting power and arranging power and also has a good feeling of use has been demanded.

JP 2007-217314 A Japanese Patent Application Laid-Open No. 11-10032 JP-A-3-261713 JP 2002-167317 A JP-T-2004-505902

The present invention has been made in view of the above-described conventional circumstances, and is an aqueous hairdressing makeup that is excellent in styling power and re-styling power while being low in viscosity, has no stickiness, is smooth, and has a light finish. The purpose is to provide a fee.

In order to solve the above problems, the present invention comprises (a) 3 to 15% by weight of a surfactant that is solid at room temperature (25 ° C.), and (b) (b ₁ ) a polyalkylene glycol polymer that is liquid at room temperature. And / or (b ₂ ) a polyhydric alcohol derivative that is liquid at room temperature, (c) a film-forming polymer, and (d) a liquid oil, and the viscosity of the system is 10,000 mPa · s or less (25 A hair styling cosmetic composition is provided that is a C-type viscometer.

The present invention also provides the hair styling cosmetic, wherein the component (a) surfactant is a nonionic surfactant.

Further, in the present invention, the component (a) has a hardness of 20 or more (measured with a card meter (25 ° C.), 400 g load, a numerical value of a scale when a pressure sensitive axis (diameter: 1 mm) enters 5 mm from the sample surface to the inside) The hair styling cosmetic composition is provided.

The present invention also provides the hair styling cosmetic composition, wherein the component (b ₁ ) is polyethylene glycol having a mass average molecular weight of 200 to 900.

The present invention also provides the above-described hair styling cosmetic, which has a viscosity of 100 mPa · s or less (25 ° C., B-type viscometer) and is used by spraying in a mist state at the time of use.

According to the present invention, there is provided an aqueous hair styling cosmetic that is excellent in hair styling power and re-hair styling power while having a low viscosity, is non-sticky, is smooth, and is light in finish.

Hereinafter, the present invention will be described in detail. In the following, POE represents polyoxyethylene, POP represents polyoxypropylene, and POB represents polyoxybutylene.

[(A) component]
The component (a) is a surfactant that is solid (solid) at room temperature (25 ° C.). In the present invention, in particular, the present inventors have found that a solid surfactant exhibits an effect for improving hair styling ability. When a surfactant that is liquid at room temperature is used instead of the component (a), sufficient hair styling power and set holding power cannot be obtained, and the effects of the present invention cannot be achieved. Examples of solid surfactants used in the present invention include anionic surfactants, cationic surfactants, amphoteric surfactants, and nonionic surfactants. In the present invention, a nonionic surfactant is preferably used. The reason is as follows.

Anionic surfactants and cationic surfactants are more irritating to the skin than nonionic surfactants, especially when sprayed in the form of a mist when in use, there is a possibility that hairdressing ingredients will adhere to the eyes and scalp. This is not preferable. Also, anionic surfactants and cationic surfactants are not preferable because they easily 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 ingredients. Moreover, compared with a nonionic surfactant, volatilization of a solvent component etc. is late | slow and a hair-styling effect tends to become slow.

In addition to the above, the cationic surfactant is not preferable in that it has a high affinity for hair, so that it softens the hair and does not exert its hair-styling ability.
