Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary hair dye composition which has good spreadability upon application, excellent water resistance after drying, and good combability.

[0002]

2. Description of the Related Art Generally, a temporary hair dye is prepared by dispersing a pigment in a solution of a alkanolamine neutralized acrylic resin or a polymer having an acid group (particularly). No. 63-218613). However, these conventional temporary hair dyes have a problem in that the pigment dissolves due to rain or sweat and stains clothes.

On the other hand, as eye makeup cosmetics such as mascara, those containing an acrylic polymer emulsion having an effective resin content of 10 to 25% by weight in order to obtain sufficient water resistance are known (Japanese Patent Publication No. 61-2676
No. 4).

However, when a large amount of the above-mentioned acrylic polymer emulsion is used in place of the polymer solution in a temporary hair dye to improve the water resistance, the spread at the time of application to the hair is poor, and the hair tip is sufficiently extended. There is a problem that the hair dye cannot be applied, the combability after drying is poor, and the pigment peels off.

[0005]

SUMMARY OF THE INVENTION The present inventor has found that if a clay mineral or a water-soluble thickener is blended in addition to a small amount of polymer latex and pigment, the coating will spread well, and since it has excellent water resistance after drying, sweat As a result, the present inventors have found that a temporary hair dye composition that does not transfer color due to dissolution of the pigment and that does not peel off the pigment or the like even when combed through can be obtained, and completed the present invention.

That is, the present invention comprises (A) a polymer latex of 2 to 5% by weight as an effective resin component, (B) a pigment, and (C) a clay mineral having gelling ability and / or a water-soluble thickener. The present invention provides a temporary hair dye composition characterized by the following.
