JP 2003-119113 A JP 2009-84226 A

  By the way, in the hair cosmetics used in the above-described form, that is, the hair cosmetics for non-gas formers, for example, the foam quality is good (fine foam can be formed). It is required to be familiar with the hair after foaming and to improve the feel of the hair, but it is not easy to make all three characteristics good, and at present, these are well balanced to a satisfactory level. It has not yet been secured.

  The present invention has been made in view of the above circumstances, and its purpose is to provide a hair cosmetic for a non-gas former that has good foam quality, is easily adapted to hair after defoaming, and can enhance the feel of the hair. It is to provide.

  The hair cosmetic composition for non-gas former of the present invention that can achieve the above object is characterized in that at least stearoxyhydroxypropylmethylcellulose and a cationic surfactant are blended.

  According to the present invention, it is possible to provide a hair cosmetic for a non-gas former that has good foam quality, is easily adapted to hair after defoaming, and can enhance the feel of the hair.

  In the non-gas former hair cosmetic composition of the present invention, stearoxyhydroxypropylmethylcellulose and a cationic surfactant are blended. By blending the cationic surfactant, the foam quality when the non-gas former hair cosmetic is discharged from the pump former can be improved, and the hair can be easily adapted to the hair after defoaming. On the other hand, in the non-gas former hair cosmetics containing a cationic surfactant, there is room for improvement, particularly in terms of the feel of the hair after treatment.

  On the other hand, by using stearoxyhydroxypropylmethylcellulose together with a cationic surfactant to make up a hair cosmetic for non-gas formers, the effect of improving the foam quality and the familiarity to the hair after defoaming are not impaired. In addition, while enhancing these, the feel of the hair after treatment can be enhanced. As described above, the hair cosmetic for non-gas former of the present invention uses the stearoxyhydroxypropylmethylcellulose and the cationic surfactant in combination to ensure the above three characteristics at a high level with a good balance.

  The blending amount of stearoxyhydroxypropyl methylcellulose in the hair cosmetic for non-gas former is 0.001% by mass or more from the viewpoint of favorably securing the effect of improving the feel of the hair after defoaming and the hair after treatment. It is preferable that it is 0.003 mass% or more. However, if the amount of stearoxyhydroxypropylmethylcellulose in the non-gasformer hair cosmetic composition is too large, the effect of improving the suitability to the hair after defoaming may be reduced. Therefore, the compounding amount of stearoxyhydroxypropyl methylcellulose in the hair cosmetic for non-gas former is preferably 0.2% by mass or less, and more preferably 0.1% by mass or less.

  As the cationic surfactant according to the hair cosmetic for non-gas former of the present invention, one or more selected from the cationic surfactants used in various known cosmetics can be used. However, since the effect of the present invention can be ensured more favorably, it is preferable to use a mono long chain alkyl quaternary ammonium salt, and to improve the familiarity to hair after defoaming more favorably Since it can be ensured, it is preferable to use a halogenated polyoxypropylene methyl diethyl ammonium, and it is more preferable to use a mono long-chain alkyl quaternary ammonium salt and a halogenated polyoxypropylene methyl diethyl ammonium together.

  As the long-chain alkyl group related to the mono long-chain alkyl quaternary ammonium salt, those having 12 to 22 carbon atoms are preferable. Specific examples of such mono long chain alkyl quaternary ammonium salts include, for example, lauryl trimethyl ammonium chloride, cetyl trimethyl ammonium chloride, stearyl trimethyl ammonium chloride, behenyl trimethyl ammonium chloride, lauryl trimethyl ammonium bromide, cetyl trimethyl ammonium bromide. And stearyltrimethylammonium bromide.

  The average added mole number of propylene oxide in the halogenated polyoxypropylene methyl diethyl ammonium is preferably 25 to 40, for example. More specifically, polyoxypropylene methyl diethylammonium chloride having an average addition mole number of propylene oxide of 25, polyoxypropylene methyl diethyl ammonium chloride having an average addition mole number of propylene oxide of 40, and the like can be mentioned.

  Moreover, cationic surfactants other than those exemplified above can also be used in the non-gas former hair cosmetic composition of the present invention.

Examples of the dialkyl type quaternary ammonium salt include distearyl dimethyl ammonium chloride, dicocoyl dimethyl ammonium chloride, dicetyl dimethyl ammonium chloride, and the like. Examples of the benzalkonium-type quaternary ammonium include benzalkonium chloride and stearyldimethylbenzylammonium chloride.

  The blending amount of the cationic surfactant in the hair cosmetic for non-gas former is preferably 0.5% by mass or more from the viewpoint of ensuring a good effect due to its use. However, if the amount of the cationic surfactant in the non-gasformer hair cosmetic is too large, the defoaming tends to be unnecessarily slow or the effect of improving the foam quality tends to be small. Therefore, the blending amount of the cationic surfactant in the hair cosmetic for non-gas former is preferably 5% by mass or less.

  When the halogenated polyoxypropylene methyl diethylammonium is used in combination with another cationic surfactant (particularly a mono-long chain alkyl quaternary ammonium salt), the blending amount of the halogenated polyoxypropylene methyl diethyl ammonium is 0.01. It is preferable to set it as mass% or more, It is more preferable to set it as 0.1 mass% or more, It is preferable to set it as 1 mass% or less, and it is more preferable to set it as 0.4 mass% or less. While blending the halogenated polyoxypropylene methyldiethylammonium in such an amount, by controlling the total blending amount of the cationic surfactant to the above preferred value, while maintaining a good foam quality improvement effect, The effect of improving the familiarity to the hair after defoaming and the effect of improving the feel of the hair can be further enhanced.

  The non-gas former hair cosmetic composition of the present invention uses water as the main dispersion medium. Note that some of the various components described above may be dissolved in water. Further, only water may be used as the dispersion medium. If necessary, an organic solvent such as a lower alcohol (alcohol having 6 or less carbon atoms) such as ethanol or isopropanol is used in an amount of 5% by mass or less based on the total amount of the dispersion medium. It may be used in combination with water in a certain amount. Moreover, it is preferable that the compounding quantity of the dispersion medium in the hair cosmetics for non-gas formers is 50-95 mass%, for example.
