Technical problem to be solved by the invention
Hair cosmetics such as conditioners and hair care agents are generally used after shampooing with a shampoo, but if the hair cosmetics are hair cosmetics having both a shampooing function and a care function, additional shampooing is not necessary, and shampooing and care can be performed using only the hair cosmetics. However, since the conventional hair cosmetics do not have sufficient foamability required for shampoo in particular, the hair washing function is not satisfactory.
In recent years, there has been an increasing demand for hair dyeing to be carried out conveniently and daily as white hair care or fashion, and hair cosmetics such as color conditioners and color care agents having both a care effect and a hair dyeing effect have been widely used. Further, if a hair cosmetic having a good hair washing function can be realized in addition to the conditioning effect and the dyeing effect, the hair washing, dyeing (dyeing), and conditioning can be performed by only one kind, so that the time and effort of the user can be greatly saved. Since white hair care is performed every day, consumers strongly desire to reduce the time and effort of white hair care.
The present invention aims to provide a hair cosmetic composition having excellent hair washing functions such as foaming property and detergency, and having excellent conditioning effect and excellent stability. It is another object of the present invention to provide a hair cosmetic composition which has excellent hair-washing functions such as excellent foamability and detergency, and which has an excellent conditioning effect and excellent stability and further has a hair-dyeing effect.
Means for solving the problems
The technical scheme of the invention is as follows.
[1] A hair cosmetic comprising: (A) alkylene glycol having 10 or more carbon atoms and/or Ethylene Oxide (EO) adduct of alkylene glycol having 10 or more carbon atoms; and (B) a higher alcohol having 12 or more carbon atoms; and (C) a cationic surfactant or an anionic surfactant.
[2] The hair cosmetic according to the above-mentioned technical means [1], which further comprises (D) a dye.
[3] The hair cosmetic according to the above-mentioned technical means [1] or [2], which further comprises (E) water.
[4] The hair cosmetic according to any one of the above aspects [1] to [3], wherein the content of the Ethylene Oxide (EO) adduct of the alkanediol (a) having 10 or more carbon atoms and/or the alkanediol having 10 or more carbon atoms is 0.06 to 28% by mass.
[5] The hair cosmetic according to any one of the above aspects [1] to [4], wherein the content of the (B) higher alcohol having 12 or more carbon atoms is 0.6 to 18% by mass.
[6] The hair cosmetic according to any one of the above aspects [1] to [5], wherein the content of the cationic surfactant or the anionic surfactant (C) is 0.2 to 8% by mass.
Effects of the invention
According to the present invention, a hair cosmetic having excellent hair washing functions such as excellent foamability and detergency, and having excellent conditioning effects and excellent stability can be provided. According to the present invention, there can be provided a hair cosmetic composition which has excellent hair washing functions such as excellent foamability and detergency, and which has an excellent conditioning effect and excellent stability and further has a hair dyeing effect.
The hair cosmetic composition of the present invention contains (A) an alkylene glycol having 10 or more carbon atoms and/or an Ethylene Oxide (EO) adduct of an alkylene glycol having 10 or more carbon atoms, (B) a higher alcohol having 12 or more carbon atoms, and (C) a cationic surfactant or an anionic surfactant. Here, a liquid crystal gel (lamellar liquid crystal and/or hexagonal liquid crystal) is formed by (a) an alkylene oxide (EO) adduct of an alkylene glycol having 10 or more carbon atoms and/or an alkylene glycol having 10 or more carbon atoms and (C) a cationic surfactant or an anionic surfactant and water, and an α -gel is formed by (B) a higher alcohol having 12 or more carbon atoms and (C) a cationic surfactant or an anionic surfactant and water. Further, due to the presence of both the liquid crystal gel and the α gel, while maintaining an excellent conditioning effect, excellent foamability which cannot be obtained by either of the liquid crystal gel and the α gel can be provided, and as a result, a hair cosmetic having a hair washing function such as excellent foamability and detergency and an excellent conditioning effect can be obtained. Further, by incorporating (D) a dye into the hair cosmetic of the present invention, a dyeing effect can be imparted, and shampooing, dyeing (dyeing), and care can be performed using only the hair cosmetic. Water is usually added to hair cosmetics, but water may be not contained in hair cosmetics, and water is added at the time of use.
The presence or absence of the formation of the liquid crystal gel and the formation of the α -gel can be confirmed by X-ray small angle scattering (SAXS) measurement, X-ray wide angle scattering (WAXS) measurement, polarization observation, FF-TEM observation, and the like.
