DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a keratinous fiber dyeing and decoloring composition having excellent conditioning effects without impairing the dyeing power and the decolorizing power.

[0002]

2. Description of the Related Art As a permanent hair dye for dyeing hair, an oxidized hair dye is obtained by applying a mixture of a color developing substance and a coupling substance to hair together with an oxidizing agent to obtain a desired coloring by a reaction of these substances. Agents are widely used. In addition, an oxidizing agent, an alkali agent, and the like are blended as essential components in a hair bleaching agent that bleaches hair by oxidatively decomposing melanin in hair.

However, when hair is treated with these agents,
In some cases, the hair becomes dry or loses its softness, giving the user discomfort. Therefore, various compounding agents have been studied (for example, JP-A-52-96849, JP-A-54-49340, JP-A-61-55887, JP-A-63-313717, and JP-A-63-313717. -57512

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a keratinous fiber dyeing or bleaching composition which is excellent in conditioning effect without inhibiting dyeing power and decolorizing power.

[0005]

DISCLOSURE OF THE INVENTION The present inventors have developed a pH control system which contains an oxidizing agent and contains a specific nonionic surfactant.
It has been found that keratinous fiber dyeing and decolorizing agents of Nos. 7 to 12 have excellent conditioning effects without inhibiting dyeing power and decolorizing power.

The present invention relates to (A) an oxidizing agent, and (B) a pen.
The present invention provides a keratinous fiber dyeing or decoloring agent containing taerythritol glyceryl isostearyl ether and having a pH of 7 to 12.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The keratin fiber dyeing and decoloring agent of the present invention contains the oxidizing agent (A) as an essential component. Examples of the oxidizing agent include hydrogen peroxide,
Persulfates such as ammonium persulfate, potassium persulfate and sodium persulfate; perborates such as sodium perborate;
Percarbonates such as sodium percarbonate; bromates such as sodium bromate and potassium bromate; and the like, with hydrogen peroxide being particularly preferred.

[0008] The amount of the oxidizing agent is 0.5 to
10% by weight is preferable, and 1.0 to 8.0% by weight is more preferable.

[0009]

[0010]

[0011]

[0012] Pentaerythritol glycer of component (B)
Lylisostearyl ether is present in the total composition in an amount of 0.01 to 0.01%.
It is preferable to add 10% by weight, particularly 0.1 to 8% by weight, and more preferably 0.5 to 5% by weight, because a sufficient conditioning effect can be obtained and the feel is good.

The pH (measured as a 10% by weight aqueous solution) of the dye or decoloring agent of the present invention is 7 to 12, preferably 8 to 1.
0. When the pH is higher than 12, irritation to the scalp, eyes and nose becomes strong, and when the pH is lower than 7, dyeing power and decoloring power are reduced.
In addition, the dyeing agent and the decoloring agent of the present invention are a two-part system or a three-part system used by mixing at the time of use.
Pentaerythritol glyceryl isostearyl ether
Le is the first agent can be incorporated into either or both of the second agents, pH after mixing is adjusted to be in the above range.

The keratinous fiber dyeing or bleaching agent of the present invention includes, in addition to the above-mentioned components, components used in ordinary hair dyes and bleaching agents, for example, color developing substances and coupling substances, basic dyes, nitro dyes, Direct dyes such as azo dyes and anthraquinone dyes, alkaline agents, surfactants other than the above, polymer compounds, solvents, oily components, thickeners, silicones, fragrances, preservatives, ultraviolet absorbers, antioxidants, sterilization Agents, pearling agents and the like can be appropriately compounded.

The keratinous fiber dyeing or bleaching agent of the present invention can be produced by a conventional method, and can be used at the time of use in the same manner as a usual two-part oxidative hair dye, two-part or three-part decolorizing agent. It is used by mixing agents.

[0016]

The keratinous fiber dyeing or bleaching composition of the present invention can provide an excellent conditioning effect without impairing the dyeing or bleaching power.

[0017]

EXAMPLES Example 1 Keratinous fiber dyeing compositions having the compositions shown in Tables 1 and 2 were produced by a conventional method. An equal amount of each of the obtained first agent and second agent is mixed, and 10 g of the mixture is applied to 10 g of gray hair tress,
Left for 20 minutes. Next, after rinsing with running water, washing with shampoo and drying, the dyeing power, finger passing and hair swelling were evaluated according to the following criteria. The results are shown in Tables 1 and 2.

(1) Dyeing power: A: Dyes uniformly and very well. ；: Dyes uniformly and well. Δ: There is slight unevenness, and there is not much staining. X: Irregularity and almost no staining.

(2) Finger passing: A: Finger passing is very good. ○: Good finger passage. Δ: It is difficult to pass through the finger. ×: finger passing is poor.

(3) Hair roughness: A: No creaking and no hair roughness. ；: The creaking is weak and there is almost no roughness. Δ: The creaking is slightly strong and slightly stiff. ×: Strong squeakiness and tingling.
