By the way, with respect to colored hair, it is desired to be able to suppress a change in color tone in daily life, and where lightness is one element of the color tone of hair, a novel composition capable of suppressing the change in lightness Is desired to be provided.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a novel hair-cleaning composition and an aerosol product capable of suppressing a change in hair brightness.

As a result of intensive studies conducted by the present inventors to solve the above-mentioned problems, as a result of a hair-cleaning composition containing an anionic surfactant and an aluminum salt, fluctuations in the lightness of the hair when the hair is cleaned are observed. The inventors have found that it can be kept small (increase in brightness stability) and have completed the present invention.
That is, the hair-cleaning composition of the present invention contains (A) anionic surfactant and (B) aluminum salt.

In the above hair-cleaning composition, potassium aluminum sulfate and/or aluminum lactate is preferably blended as the (B) aluminum salt.

In the hair-cleaning composition, it is more preferable that potassium aluminum sulfate and aluminum lactate are blended as the (B) aluminum salt. By using potassium aluminum sulfate in combination with aluminum lactate, the fluctuation of the lightness of the hair can be further suppressed.

The aerosol product of the present invention is a container in which the above hair-cleaning composition and a propellant are filled.

According to the hair-cleaning composition and the aerosol product of the present invention, the change in the lightness of hair can be suppressed to a small level.

In particular, from the viewpoint of enhancing the effect of suppressing the fluctuation of the lightness of hair to be small, it is preferable to mix both potassium aluminum sulfate and aluminum lactate. In this case, the mass ratio of aluminum lactate to potassium aluminum sulfate is preferably 0.5 or more and 2.0 or less, and more preferably 0.7 or more and 1.3 or less.

The amount of the aluminum salt compounded in the hair-cleaning composition is preferably 0.01% by weight or more and 3% by weight or less, more preferably 0.1% by weight or more and 2% by weight or less, and 0.2% by weight. % Or more and 1% by weight or less is more preferable. When the blending amount is 0.01% by weight or more, the effect of suppressing fluctuation in the lightness of hair is easily obtained. On the other hand, when the blending amount is 3% by weight or less, it is possible to suppress the stiffness of the hair after washing.

(Arbitrary ingredient)
In addition to the above anionic surfactants and aluminum salts, known hair-cleaning composition (shampoo) components, for example, amphoteric surfactants, nonionic surfactants, lower alcohols, polyhydric alcohols, sugars, polymer compounds , Amino acids, animal and plant extracts, inorganic compounds, fragrances, preservatives, charcoal and the like may be contained. Among these, it is preferable to contain a polymer compound, particularly a cationic polymer. In addition, you may use each arbitrary component individually or in combination of 2 or more types.

The above-mentioned cationic polymer is a component that improves the finger-passing property at the time of washing. Examples of the cationic polymer include cationized cellulose, cationized guar gum, vinylpyrrolidone/N,N-dimethylaminoethylmethacrylic acid copolymer diethyl sulfate, acrylamide/acrylic acid/dimethyldiallylammonium chloride copolymer, Examples thereof include N,N-dimethylaminoethyl diethylsulfate sulfate/N,N-dimethylacrylamide/polyethylene glycol dimethacrylate copolymer. The content of the cationic polymer in the hair-cleaning composition is preferably 0.1% by mass or more and 1% by mass or less.

The pH of the hair-cleaning composition at 25° C. is preferably 3.0% by mass or more so that the function of the anionic surfactant as a surfactant can be exhibited well. Further, the pH is preferably 6.0 or less, preferably 5.5 or less, more preferably 5.0 or less, and further preferably 4.5 or less in order to stably dissolve the aluminum salt.

(Formulation)
The dosage form of the hair-cleaning composition of the present embodiment is not particularly limited, and examples thereof include liquid forms. Here, the viscosity of the hair-cleaning composition is, for example, 10 mPa·s or more and 1,000 mPa·s or less. In addition, when the viscosity is measured using a B-type viscometer (temperature: 25° C., rotor: appropriately set according to viscosity, rotor rotation speed: 60 rpm), a value obtained after 60 seconds from the start of viscosity measurement Is.

(Aerosol product)
The hair-cleaning composition of the above embodiment can be used as an aerosol product by using it as a stock solution and filling it into a pressure resistant container together with a propellant.
As the propellant, at least one of carbon dioxide, isopentane, and liquefied petroleum gas may be used, or two or more thereof may be used. Further, the propellant may contain components other than carbon dioxide, isopentane, and liquefied petroleum gas as long as the effects of the present invention are not impaired.

Carbon dioxide is an active ingredient that imparts a blood circulation promoting effect, and also functions as a propellant. This carbon dioxide is filled in the pressure resistant container as a gas. A part of it is dissolved in the liquid in the pressure resistant container and is foamed on the skin by the injection of the propellant. Gaseous carbon dioxide present in the foamed foam and carbon dioxide dissolved in the liquid have a blood circulation promoting action on the skin.

Both isopentane and liquefied petroleum gas are components that form bubbles. It is speculated that this isopentane contributes to the sustainability of the foam. On the other hand, liquefied petroleum gas is presumed to contribute to the initial foaming property due to its high volatility.

As the liquefied petroleum gas, at least one of propane, n-butane, and i-butane can be used. It is preferable that n-butane and i-butane coexist because they are excellent in foam formation at low temperatures.

The filling amount of the propellant is preferably 0.5 parts by mass or more and 30 parts by mass or less, more preferably 1 part by mass or more and 20 parts by mass or less, and more preferably 2 parts by mass with respect to 100 parts by mass of the stock solution which is the composition for hair washing. More preferably, it is not less than 15 parts by mass and not more than 15 parts by mass. By setting the filling amount of the propellant in the above range, the stock solution which is the hair-cleaning composition can be efficiently jetted.

(Pressure resistant container)
The pressure-resistant container is a pressure-resistant container filled with a stock solution and a propellant, which is a hair-cleaning composition. As this pressure-resistant container, a known pressure-resistant container used for aerosol products can be adopted, and is formed of, for example, a metal such as aluminum, an aluminum alloy, tin plate or steel. The pressure-resistant container may have a resin layer laminated on the inner surface or may have an inner bag inside.

(Use)
