Abstract

PROBLEM TO BE SOLVED: To provide an oxidation hairdye capable of returning the hair brightened by an external factor such as a bleaching agent by uniformly dyeing the hair without selecting the degree of the damage. SOLUTION: This two-pack type oxidation hairdye composition includes an oxidation dye in the first agent, and an oxidant in the second agent, and the pH at the time of use is regulated so as to be 8-9.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the degree of hair damage.
Bright hair with stable hair dyeing power not affected by
The present invention relates to an oxidative hair dye composition for returning hair to its original hair color.
You. [0002] Oxidative hair dyes penetrate the oxidation dye into the hair.
And oxidative polymerization in the hair
It is produced and dyed. Generally such dyeing
Hair preparations use oxidation dye intermediates such as paraphenylenediamine.
A first agent as a main component and an oxidizing agent such as hydrogen peroxide as a main component
And a second agent. Both of the above agents apply to hair dye
Therefore, they are mixed and used. [0003] The first agent is usually mixed with an alkali agent.
Adjusted to alkaline. This is the mixing with the second agent
PH is adjusted to 10 or more to moisturize the hair
To make the oxidation dye intermediate easily penetrate into the hair
To promote the release of nascent oxygen from the second oxidant
Is indispensable for This nascent oxygen is an oxidation dye
The intermediates are oxidized to produce colored substances,
It acts to decompose hair and decolorize hair. That is,
Ip's hair dye does not bleach the dark hair of gray hair
Dyeing the entire color to the desired color
You can. [0004] However, this alkaline oxidative hair dye is
Influence on hair due to strong action of lukari and oxidizing agents
Was also large and could cause hair damage. That's it
Alkaline as a hair dye that dispels concerns
Oxidative hair dye adjusted to acidic without blending
I have. [0005] In recent years, the fashion of hair has been increasing.
Decoloring hair with bleach etc. is one of them
One. Also, whether you like it or not,
Hair becomes brighter due to external factors such as heat and ultraviolet rays
Sometimes. Many of these lightened hairs
If the bleach or dryer
The more the number of treatments, the longer the time
That is, the further to the hair end, the worse the damage. Moreover,
When external factors such as brushing are added, the degree of damage
I will advance. [0006] Hair that has been lightened in this way is subject to the oxidation described above.
It can be returned to black hair with a hair dye, but as mentioned above,
The degree of damage from the root to the tip of a single hair is large
Conventional hair dyes must be evenly dyed
Was very difficult. Alkaline oxidation accounts for most of the market
Hair dye is weakly dyed on hair tips with high damage
Hair loss, poor fit, and acidic oxidative hair dye
Only the hair ends are dyed too deeply, so only the hair ends
It becomes black and unnatural finish.
Was. The present invention aims at solving the above problems.
External factors such as bleaching agents
Hair that has become brighter, regardless of its degree of damage,
Provides an oxidative hair dye that can be dyed uniformly
It is. Means for Solving the Problems The present inventors have made intensive studies.
As a result, the pH at the time of using the oxidative hair dye is adjusted to 8-9.
By doing so, the hair dyes evenly, choosing the degree of damage to the hair,
Finding that you can restore your lightened hair color
Was. That is, the gist of the present invention is that
A medicine to restore hair that has been lightened by factors to its original black hair
The first agent contains an oxidation dye and the second agent contains an oxidizing agent
And the pH at the time of use is adjusted to 8-9
And a two-part oxidative hair dye composition. BEST MODE FOR CARRYING OUT THE INVENTION Oxidative hair dye for restoring hair color of the present invention
Has a pH of 8 to 9, preferably 8.3 to
8.7. If the pH is lower than 8, dyed damaged hair
Stronger, if the pH is higher than 9, sufficient dyeing for damaged hair
Hair power is no longer obtained, and in all cases, hair is evenly dyed
It becomes difficult. The method for adjusting the pH is not particularly limited. Only
In general, the oxidizing agent contained in the second agent is hydrogen peroxide.
Yes, to ensure its stability, the pH of the second agent should be 2
Adjusted to ~ 4. As this pH adjuster, a known inorganic
Acids or organic acids such as hydrochloric acid, phosphoric acid, tartaric acid, que
Acid, succinic acid, acetic acid, lactic acid, formic acid, etc.
Acid can be added as needed. Therefore, the pH at the time of use is adjusted to 8-9.
For this purpose, it is necessary to make the first agent alkaline. This pH
As a regulator, for example, ammonia water, monoethanol alcohol
Min, isopropanolamine and 2-amino-2-me
Alkanolamines such as tylpropanol, hydroxylation
Hydroxide of alkali (earth) metal such as sodium, L
-Salts such as arginine, lysine, alanine and leucine
Uses commonly used alkaline agents such as basic amino acids
It can be blended accordingly. The amounts of these pH adjusters are the first and the second.
The amount is such that the pH when the two agents are mixed becomes 8-9. [0015] The hair dye composition of the present invention comprises a liquid, an emulsion,
General, such as cream, gel and aerosol mousse
Can be applied to any of the dosage forms known. The hair dye composition of the present invention usually contains
