Description

  The present invention relates to a pre-shampoo-type hair treatment composition used before shampooing with a shampoo composition, a hair treatment set of a shampoo composition and a pre-shampoo-type hair treatment composition, and a treatment method using these. is there.

  The finish of hair has been desired in the past. On the other hand, those who suffer from thinning hair are concerned about the volume reduction (appearance of thinning hair) of their hair, and an effect of increasing the volume (providing a soft feeling) after washing their hair is desired.

  Regarding the provision of a soft feeling so far, a method of penetrating and supplementing hair with components similar to hair such as collagen derivatives and keratin derivatives (Japanese Patent Laid-Open No. 2-53712), and the hair surface with natural polymer compounds, etc. A method of coating (JP-A-4-308525) is known.

  However, when the hair is treated with a hair conditioner or the like for the purpose of improving the finish of the hair after shampooing, there is a problem that the softness of the top of the head cannot be obtained due to the effect of the conditioning components remaining on the hair. On the other hand, when a pre-shampoo composition was used before shampooing, the conditioning components were washed away by the subsequent shampooing, and the finish of the hair was insufficient. From the above, it is difficult to achieve both good hair finish and fluffiness, and it has been desired not only to improve the appearance of thin hair but also to prevent thin hair itself.

About 0.8 g of polyethylene glycol is weighed accurately, placed in a pressure-resistant stopper bottle of about 200 mL, added with about 25 mL of pyridine, heated to dissolve and allowed to cool. Separately, 42 g of phthalic anhydride is taken, added to a 1 L light-shielded stoppered bottle containing 300 mL of freshly distilled pyridine, and shaken vigorously to dissolve, then left for 16 hours or longer. 25 mL of this solution is accurately weighed, sealed in the pressure-proof stopper bottle, wrapped in a strong cloth, and placed in a water bath heated to 98 ° C. ± 2 ° C. in advance. At this time, the liquid in the bottle is immersed in the liquid in the water bath. After heating at 98 ° C. ± 2 ° C. for 30 minutes, the bottle is removed from the water bath and allowed to cool to room temperature (1-30 ° C., the same applies hereinafter). Next, 50 mL of 0.5 mol / L sodium hydroxide solution is accurately added, and this solution is titrated with 0.5 mol / L sodium hydroxide solution. At this time, 5 drops of phenolphthalein / pyridine solution (1 → 100) is used as an indicator.
