Abstract

PROBLEM TO BE SOLVED: To prepare the subject stable composition without losing aroma even in a formulation with time by including hydrogen peroxide and an aromatic compound stable to the hydrogen peroxide therein. SOLUTION: This composition is obtained by including hydrogen peroxide and one or more simple perfumes or a compound perfume selected from aromatic compounds (phenylaetaldehyde, dimethyl acetal, 2,6-dimethyl-2-heptanol, etc.) in an amount of 0.001-6wt.% (preferably 0.01-1wt.%) based on the total amount of the composition therein, regulating the pH of the composition to 1.5-5 (preferably 2.5-4.5) with an acid (hydrochloric acid, sulfuric acid, phosphoric acid, etc.) and combining an alkali metallic salt, etc., of an acid so as to provide a pH buffering ability (e.g. sodium citrate) therewith. The resultant composition is excellent in hair dyeing or decoloring effects.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair treatment composition containing hydrogen peroxide and a specific odorant compound, which is used for a hair dye for hair and the like.

[0002]

2. Description of the Related Art A hair treatment composition containing hydrogen peroxide is excellent in oxidizing power and also has a decolorizing effect of decomposing melanin pigments. Its usefulness as a dye is known. on the other hand,
Ordinary hair treatment compositions contain a fragrance to cover the raw odor and enhance palatability, and have an aroma. However, when a commonly used fragrance is added to a hair treatment composition containing hydrogen peroxide, the composition is decomposed by the hydrogen peroxide, and loses its fragrance over time or emits a bad smell. There was a problem that was bad.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a hair dyeing or bleaching effect which contains hydrogen peroxide, and
It is an object of the present invention to provide a hair treatment composition having a fragrance that is stable in the preparation over time.

[0004]

Means for Solving the Problems The present inventors have made intensive studies to obtain such a hair treatment composition, and as a result, have added a stable odorous compound to hydrogen peroxide and a specific hydrogen peroxide. As a result, a composition having desired properties was obtained, and it was found that the above problems could be solved. Thus, the present invention was completed. That is, the present invention contains (1) hydrogen peroxide and (2) one or more single or mixed flavors selected from fragrance compounds stable to hydrogen peroxide, and has a pH of 1 or more. 0.5 to 5 is provided.

[0005]

DETAILED DESCRIPTION OF THE INVENTION When a commonly used fragrance is incorporated into a hair treatment composition containing hydrogen peroxide, it is impossible to obtain a stable fragrance over time. When the hair treatment composition of the present invention contains a specific fragrance compound, it is possible to obtain a stable medicine containing hydrogen peroxide and not impairing the fragrance over time.

[0006] Hydrogen peroxide used in the present invention, for example, in an oxidative hair dye, has an oxidizing effect of decomposing melanin to decolorize hair and polymerizing an oxidative dye that has penetrated into hair. It is used as a raw material for cosmetics. This hydrogen peroxide is appropriately included in an amount that exhibits the desired effect, but usually 0.1 to 0.1% based on the total amount of the composition.
6% by weight.

The fragrance compound used in the present invention does not impair the stability of hydrogen peroxide over time in a hair treatment composition containing hydrogen peroxide, and the structure itself of the fragrance and its fragrance do not significantly change. You need to carefully choose a stable one. In addition, in the actual formulation, in many cases, among the fragrance compounds selected in this way, a combination of several kinds is taken into consideration in consideration of the fragrance according to the taste and the flavor.

[0008] From the viewpoint of aroma, 0.001 to 6% by weight based on the total amount of the composition, from the viewpoint of aroma,
It is preferably used in the range of 0.01 to 1% by weight. In addition, other fragrances may be combined according to the fragrance and taste as long as the stability is not impaired.

The pH of the hair treatment composition of the present invention is 1.
5 to 5, preferably 2.5 to 4.5, and the pH is 1.
If it is less than 5, safety such as skin irritation is not preferable, and if it exceeds 5, stability of hydrogen peroxide deteriorates. An acid is used to adjust the composition to a suitable pH.
Examples of the acid include inorganic acids such as hydrochloric acid, sulfuric acid, phosphoric acid, and nitric acid, or acetic acid, citric acid, tartaric acid, propionic acid, lactic acid, salicylic acid, glycolic acid, and succinic acid.
Organic acids such as malic acid and butyric acid;
Species or two or more species can be used arbitrarily, and among them, hydrochloric acid, sulfuric acid, phosphoric acid, acetic acid, propionic acid, lactic acid, salicylic acid, glycolic acid, and succinic acid are preferable. Particularly, phosphoric acid, lactic acid, acetic acid, and glycolic acid are preferable. It is preferable because the hair dyeability is remarkably improved. In addition, by combining alkali metal salts of these acids, such as sodium citrate, sodium hydroxide, disodium hydrogen phosphate, potassium hydroxide, etc., it is possible to provide a pH buffering ability within a suitable pH range. it can.

The composition of the present invention can be formed into various forms such as gel, paste, cream, etc., according to each form, as long as the effects of the present invention are not impaired.
For example, surfactants such as anionic surfactants, cationic surfactants, nonionic surfactants and amphoteric surfactants; aromatic alcohols, higher alcohols, polyhydric alcohols, higher fatty acids, paraffin wax, hydrocarbon oils, esters Oils, oils such as silicone oils; volatile solvents, polymers, preservatives, antioxidants, ultraviolet absorbers, metal chelating agents and dyes and other known cosmetic ingredients are appropriately blended, and in a manner known per se, for example, Oxidative hair dyes, decolorizers, decolorizers, and oxidative hair dyes can be used.

In order to use the hair treatment composition of the present invention, an appropriate amount is usually applied to the hair, and then the hair is washed with a shampoo or the like, or naturally dried or dried with a drier. In particular, the composition of the present invention is preferably subjected to a heating treatment before, during or after the application of the hair, because the decolorizing property and the hair dyeing property are further improved.
As an example of this heating treatment, after applying the composition of the present invention to the hair, for example, a steamer, steam such as a steamed towel, warm air of a dryer, heat the application portion with heat such as far infrared rays,
Then, it can be carried out by washing away the excess composition or drying without washing off. Usually, the heating treatment is suitably performed at 40 to 90 ° C. for 30 seconds to 30 minutes. Similar effects can be obtained by applying a heated composition.
