Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an acidic hair dye composition for hair which, while satisfying the essential conditions as an acidic hair dye such as dyeing property and washing resistance, has a good feel during use. It is a thing.

[0002]

2. Description of the Related Art Conventionally, acidic hair dyes for hair include acidic dyes, alcohols (mostly benzyl alcohol is used), an organic solvent and an acid for pH adjustment (mostly citric acid). Is used as a main component, and a thickener is added to this to prevent it from dripping from the hair during use, and is commercially available. However, pH adjustment is 1.5 ~
4.5 (this range is preferable for obtaining good dyeing property and washing resistance, average is around 3), and it is necessary to make it to a considerably strong acidic side, and it is used under such conditions Thickeners are fairly limited. Among them, xanthan gum is known as an effective thickener (Japanese Patent Publication No. 2-322).
No. 53). However, conventionally known hair dyes containing oxatan gum have poor fluidity, and when applied to the head after being taken by hand, they are difficult to drop as a lump or spread on the hair. Therefore, it is difficult to obtain a product having satisfactory dyeing property, and improvement in practical use has been desired. The present invention solves such conventional drawbacks, and satisfies the essential conditions as an acidic hair dye, such as dyeing property and wash resistance, while providing fluidity and good usability to the acidic hair dye composition for hair. The purpose is to provide goods.

[0003]

According to the present invention, xanthan gum is used as a thickener in an amount of 0.5 to 5.0% by weight, bentonite and / or crosslinkable sodium polyacrylate in a total amount of 0.1 to 1. It is an acidic hair dye composition for hair characterized by containing 0% by weight. In the present invention, xanthan gum, which is stable under acidic conditions, is used as a thickener, and bentonite and / or crosslinkable sodium polyacrylate are used together as a usability improver. These polymer compounds greatly improve the usability as compared with the acidic hair dye containing only xanthan gum, but do not significantly change the viscosity of xanthan gum alone.

In the present invention, as a result of examining various inorganic polymers that can coexist with xanthan gum, magnesium silicate magnesium aluminum silicate containing a large amount of magnesium salt (10% or more as MgO).
Moreover, those containing foreign substances were not stable and could not coexist with xanthan gum. However, it was confirmed that bentonite was very effective. In addition, most organic polymers have a pH in the vicinity of neutrality and often have poor stability when adjusted to 1.5 to 4.5, and slightly crosslinkable sodium polyacrylate gives good results. Examples of the xanthan gum include Keltrol, Keltrol T (both are trade names manufactured by Koei Kogyo Co., Ltd.), and the compounding amount thereof is 0.5 to 5.0% by weight. If the amount is less than 0.5% by weight, the viscosity is low when applied to the hair, causing dripping, and if the amount exceeds 5.0% by weight, the viscosity is high and fluidity cannot be obtained. Examples of bentonite include Kunipia G-4 (trade name, manufactured by Kunimine Industries Co., Ltd.), and examples of crosslinkable sodium polyacrylate include Sumikagel NP-1020.
(Sumitomo Chemical Co., Ltd. product name), Aquaric CA (Nippon Shokubai Chemical Co., Ltd. product name) and the like. The total amount of these components is 0.1 to 1.0% by weight. 0.1% by weight
If it is less than 1.0%, the effect is not exhibited, and if it exceeds 1.0% by weight, fluidity is lost.

Further, in the present invention, 0.5 to 5.0% by weight of xanthan gum is used as a thickener, and 0.1 to 1.0% by weight of bentonite and / or crosslinkable sodium polyacrylate in total. Further, there is provided an acidic hair dye composition for hair, comprising one or two or more kinds of silicone in a total amount of 0.01 to 5.0% by weight. According to the present invention, by further adding 0.01 to 5.0% by weight of silicones to the acidic hair dye composition, the feeling of use is greatly improved. Therefore, the composition of the present invention is a one-pack type hair dye composition, and the characteristics of good usability are utilized, and the rinse / post-rinse /
The composition can also be applied as a hair-dyeing composition.
