Description

  The present invention relates to a gel-like color shampoo composition that has excellent hair dyeing properties, has a viscosity that does not sag, and has good viscosity stability over time.

  In recent years, color shampoos are known as products for changing the nuances of hair color for fashion and concealing gray hair due to aging. Color shampoos are commonly used because they are characterized by being gradually dyed by continuous use in daily shampooing and can be used easily. For example, color shampoo compositions such as Patent Document 1 and Patent Document 2 are known.

  As a shampoo composition, in recent years, a gel-like shampoo composition having an appropriate viscosity is preferred from the viewpoint of good usability. As a thickening method for main shampoo compositions, there is a method for developing a thickening action using an electrical interaction between molecules of an anionic surfactant and an amphoteric surfactant, or a polymer thickener. And the like are known (Patent Documents 3 and 4).

  However, when the color shampoo composition containing a basic dye is thickened by a conventional method, the basic dye exhibits a cationic property, which is caused by an electrical interaction between the anionic surfactant and the amphoteric surfactant. Inhibits thickening or significantly reduces the effect of polymer thickeners. For this reason, it has been difficult to thicken the color shampoo composition by the conventional thickening method. Furthermore, it is possible to temporarily increase the viscosity to a sufficient viscosity by adding a large amount of a polymer thickener, but the viscosity stability over time is extremely poor, and an appropriate viscosity can be maintained over time. It was difficult. For this reason, when the color shampoo composition which does not have sufficient viscosity is used, there was a problem that the color shampoo composition drips from the hand and stains the periphery.

  As a result of intensive studies to solve the above problems, the present invention is a gel color shampoo composition containing a basic dye, comprising (A) an amphoteric surfactant, (B) an alkylsulfuric acid or a salt thereof, (C ) Polyoxyethylene methyl glucoside fatty acid ester, (A) / (B) = 2.5-30, and viscosity at 20 ° C. is 5,000 mPa · s-40,000 mPa · s It is to provide a gel-like color shampoo composition.

When the said (C) component is less than 0.05%, there exists a possibility that there may not be sufficient thickening effect | action. When the component (C) exceeds 10.0%, there is a possibility that a feeling of nullness may be felt at the time of washing, and the usability may be deteriorated.

  The gel color shampoo composition according to the present invention contains a basic dye. This has the effect of dyeing hair.
