  By the way, recently, curl styles in which the entire hair is curled by curling iron processing or permanent wave processing have become popular. In such curl-style hair, it is desired to create a movement with a feeling of air in the style formation, more specifically, to float and hold a thin hair bundle. Therefore, for a hairdressing composition applied to curled hair, such a style, that is, a setting force that can float and hold a thin hair bundle (hereinafter referred to as “setting force” in the present specification is not particularly noted). As long as it is required to have this setting power, the hair after application is soft (in addition to the softness of the hair itself) And that the hair is in a light state that is not heavy and sticky. The same shall apply hereinafter).

  Conventional hair styling agents containing waxes and waxes still have room for improvement in terms of both the setting power and the action of imparting softness to the hair after application.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a hair styling composition that is excellent in setting power and can impart good softness to the hair after application.

  The hair styling composition of the present invention capable of achieving the above object is characterized in that at least a solid wax or hydrocarbon at 25 ° C., dimer linoleic acid ester and branched acyl lactate are blended. is there.

  ADVANTAGE OF THE INVENTION According to this invention, the hair-styling composition which is excellent in setting power and can provide favorable softness to the hair after application | coating can be provided.

  In the hairdressing composition of the present invention, solid wax or hydrocarbon at 25 ° C., dimer linoleic acid ester, and branched acyl lactate are combined, and these are applied while improving the setting power. Good softness can be imparted to the later hair.

  Examples of the wax that is solid at 25 ° C. include beeswax, carnauba wax, candelilla wax, rice bran wax, lanolin, and mole. Examples of hydrocarbons that are solid at 25 ° C. include paraffin, petrolatum, microcrystalline wax, and ceresin. As the wax that is solid at 25 ° C. and the hydrocarbon that is solid at 25 ° C., those exemplified above may be used alone or in combination of two or more. In addition, since the applicability to the hair can be improved and the hairdressing composition can be easily adjusted to a setting force according to the hairstyle, a wax that is solid at 25 ° C. and a hydrocarbon that is solid at 25 ° C. It is preferable to use together. In addition, it is preferable to use candelilla wax and / or beeswax as a solid wax at 25 ° C. in that both the effect of improving the setting power and the effect of imparting softness to the hair are improved. More preferably it is used.

  The blending amount of the wax or hydrocarbon that is solid at 25 ° C. in the hairdressing composition is preferably 0.5% by mass or more, and 1.0% by mass or more from the viewpoint of ensuring the effect of using these. It is more preferable that However, if the amount of the wax or hydrocarbon in the hairdressing composition is too large, among the effects of imparting softness to the hair, there is a possibility that the effect of improving the fingering property may be reduced. The amount of the wax or hydrocarbon is preferably 20.0% by mass or less, and more preferably 10.0% by mass or less.

  Examples of the dimer linoleic acid ester include dimer linoleic acid and dimer linoleyl, an ester of dimer linoleic acid and dimer diol; and dimer linoleic acid di (isostearyl / phytosteryl).

  The blending amount of dimer linoleic acid ester in the hairdressing composition is preferably 0.2% by mass or more, more preferably 0.5% by mass or more, from the viewpoint of better securing the effects of the use thereof. Is more preferable. However, if the amount of dimerlinoleic acid ester in the hairdressing composition is too large, the effect of imparting softness to the hair may be reduced, so the amount of dimerlinoleic acid ester in the hairdressing composition is It is preferable that it is 3 mass% or less, and it is more preferable that it is 1.5 mass% or less.

  In the hairdressing composition of the present invention, a branched acyl lactate is used.

  The blending amount of the branched acyl lactate in the hairdressing composition is preferably 0.2% by mass or more from the viewpoint of better ensuring the effect of its use. However, if the amount of the branched acyl lactate in the hairdressing composition is too large, the setting power becomes too strong, and there is a possibility that the hair after application may become stiff and the emulsified hairdressing composition. In this case, emulsification may be difficult. Therefore, the blending amount of the branched acyl lactate in the hairdressing composition is preferably 5.0% by mass or less, and more preferably 2.0% by mass or less.
