Description

Oil-in-water hair composition

Technical Field

The present invention relates to an oil-in-water type hair composition, and more particularly to a hair composition for temporary hair dyeing and styling.

Background

In recent years, hair dyes have been popular because of the increase in the population required for the dyeing of aging white hair and the prevalence of dyed hair. Hair dyes are classified into temporary hair dyes, semi-permanent hair dyes, and permanent hair dyes according to the persistence of color after coloring hair. The semi-permanent hair dye and the permanent hair dye have the advantage that the hair dye is difficult to fall off even if the hair dye is washed by shampoo, but have the complicated operation. On the other hand, the temporary hair dye has the advantage that it can be used easily, and can be applied only to a target site, and can rapidly dye hair, and is most suitable for use before going out. Further, since the temporary hair dye can be easily washed off with a shampoo, it is convenient if the hair dye is not satisfactory in color or is changed to another color, and the demand in the market is also large.

Conventionally, a temporary hair dye is composed of a film-forming agent (coating agent) for fixing a coloring material to hair to prevent secondary contamination to clothes and the like, a coloring material mainly composed of an inorganic pigment having high covering power, and a quick-drying volatile solvent such as ethanol, and a method of filling a substance for forming a coloring coating film on hair to cover white hair into an aerosol can together with an aerosol propellant to obtain a spray-like substance, applying the spray-like substance to the surface of hair, and drying to fix the substance.

On the other hand, styling agents are agents for hair styling and are known in various forms such as liquid, gel, paste, and solid forms. In order to exhibit moldability, which is a main function thereof, a film-forming polymer or an oil which is solid at room temperature is often used. In particular, the oil-in-water type styling agent has advantages of being easily spread, being capable of being uniformly applied to hair, being excellent in styling retention and in restorability capable of giving random swing, cubic effect, and the like to hair, and being capable of easily obtaining high styling power (for example, patent documents 1 and 2 and the like).

There are also known oil-in-water type agents among temporary hair dyes (for example, patent documents 3 and 4). The oil-in-water type temporary hair dye can be applied to fingers and molded, has excellent usability, and can simultaneously provide a certain molding force due to the added film-forming agent.

Disclosure of Invention

[ problems to be solved by the invention ]

However, a film-forming agent such as an emulsion resin is solidified at a low temperature, and aggregation of an emulsion occurs in a high-temperature environment, so that the emulsion is unstable, and the formulation itself is liable to become unstable, and a large amount of the emulsion cannot be mixed, and therefore, it is difficult to improve the molding force. In the case of the oil-in-water type, it is difficult to improve the quick drying property because a quick drying type volatile solvent such as ethanol cannot be mixed in a large amount because of the fear that the emulsion stability is impaired. Further, in the case of the oil-in-water type, it is difficult to stably mix the powder on the hair in an amount to obtain a sufficient color development because the powder absorbs oil.

In view of the above circumstances, an object of the present invention is to provide an oil-in-water hair composition having improved styling ability, quick-drying properties, and color tone compared to conventional oil-in-water temporary hair dyes, and having sufficient stability.

[ means for solving problems ]

As a result of intensive studies to solve the above problems, the present inventors have found that by mixing a specific amount of pearl powder and other coloring agents in an oil-in-water composition containing a specific amount of water and setting the mass ratio of pearl powder to surfactant within a specific range, the styling power, quick-drying property and color development can be improved as compared with conventional oil-in-water temporary hair dyes, and the dispersibility and storage stability of the oil-in-water composition can be sufficiently ensured, and have completed the present invention based on this finding.

Namely, the present invention provides an oil-in-water type hair composition comprising 30 to 60 mass% of water, oil, 3.5 to 30 mass% of pearl powder, 1 mass% or more of a colorant (excluding colorants contained in the pearl powder), and a surfactant, wherein the mass ratio of the pearl powder to the surfactant is 3:1 to 1: 1.

The oil-in-water hair composition of the present invention, having the above-described structure, can exhibit a higher styling ability, quick-drying property, and color feeling than conventional oil-in-water temporary hair dyes, and can have sufficient stability.

The oil-in-water hair composition of the present invention preferably contains 2% by mass or more of an anionic surfactant as a surfactant, from the viewpoint of achieving a higher level of compatibility between quick drying properties, styling ability, color development properties, and usability.
