Description

 Technical Field [0001] The present invention relates to a composition for scalp coloring,

The present invention relates to a composition for scalp coloring and a method for producing the same, and relates to a composition for scalp coloring which has excellent coloring power and color retention and is easy to use, and a method for producing the same.

With the development of the industry, digital has developed and has become a target of envy of ordinary people with the small face and small hair of the broadcasters. There is a new word, "Sodu," which recognizes that small heads and small faces are beautiful as one of the major requirements of current trends and beauty.

Hair line hair shape, position, hair thinning, color and so on determine the size and face type of the face corresponds to an element that recognizes as a small face, and therefore efforts to maintain a small face with changes in hair style It has been consistently done.

However, the hair line is a part of a living tissue composed of hair. There are differences in hair position, hair thinning, and thickness of hair depending on individual biological characteristics. Particularly, there is a problem that the number of hair gradually decreases or becomes thin It is very difficult to keep a beautiful hairline and a lot of hair thinning constantly.

In hair makeup, shading and eye shadow are used instead of hair products to fill the hairline area to maintain the hairline. However, such products have a very short duration and a lot of problems.

On the other hand, Japanese Patent Laid-Open Publication No. 2006-063020 (prior art 1) discloses a method of coloring skin around eyebrows rather than hair lines using dihydroxyacetone. However, the prior art 1 does not disclose a method for increasing the stability and feel of a cosmetic product by blocking metal ions in order to prevent catalytic action of a trace amount of metal ion contained in the composition. Therefore, Showed no limit.

Korean Patent No. 10-1659896 (Prior Art 2) discloses that dihydroxyacetone is used to color skin around eyebrows, and further disodium dithiene is used to block metal ions. Was released. However, in the prior art document 2, only the skin coloring around the eyebrows is used. Unlike the coloring of the hair line, the eyebrow-shaped coating film is formed using polyvinyl alcohol or polyvinylpyrrolidone, The problem to be solved is very different from the hair line which has to emphasize extreme naturalness. In other words, even if eyebrow makeup or eyebrow tattoo is done intensely so that the artificial feeling around the eyebrows is strong, it is natural that it is seen as a part of makeup, but if you draw a line in the same way as eyebrow makeup on the hairline, will be. In addition, in the prior art document 2, since most of the solvent occupies water, it does not help dissolving other water-soluble components, so that when applied to the eyebrows, components are precipitated on the surface of the eyebrows.

Accordingly, there is a demand for development of a composition for coloring hair line scalp that exhibits natural coloring in hair line, exhibits excellent coloring sustainability, and does not precipitate foreign substances, so that it can go out immediately after application.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. The present invention can be variously modified and may have various embodiments, and specific embodiments will be described in detail with reference to the drawings. It should be understood, however, that the invention is not intended to be limited to the particular embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

Unless defined otherwise, all terms used herein, including technical or scientific terms, have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Terms such as those defined in commonly used dictionaries are to be interpreted as having a meaning consistent with the contextual meaning of the related art and are to be interpreted as either ideal or overly formal in the sense of the present application Do not.

Hereinafter, the present invention will be described in more detail.

The present invention relates to a composition for scalp coloring and a method for producing the same, and exhibits an effect of sustaining a coloring effect for about 7 days by one use.

The present invention has a function of rapidly absorbing and not allowing a region to be imparted with a color of a hair line to be used by using an ionic dye and a pigment which are not irritating to the skin.

The composition of the present invention basically includes a solvent, a coloring agent, a preservative, and a coloring agent. As a solvent, purified water, dipropylene glycol, propylene glycol, methylglucose-20 and ethanol may be used. In the present invention, purified water used as a solvent is used in an amount of 15 to 50 wt%, and when it is less than 15, solubility of various water-soluble components is lowered.

Dipropylene glycol is used as a solvent in an amount of 1 to 10% by weight and helps dissolve the water-soluble component. Propylene glycol helps dissolve 1 to 10% by weight of water-soluble components with a solvent. Methylgluceth-20 solvent helps dissolve 1 to 10% by weight of water-soluble components.

According to the present invention, the residual of water-soluble components is suppressed according to the use of these solvents, so that keratinous precipitates are remarkably reduced upon application to the scalp, penetrating deeply into the stratum corneum and skin of the epidermis, thereby exerting excellent coloring power.

Ethanol is used in an amount of 5 to 20% by weight. When it is less than 5, the volatilization rate is lowered and the drying speed of the composition may be lowered. If it is more than 20, the volatilization rate is too fast to be stimulated.

Accordingly, the present invention relates to a process for the preparation of a pharmaceutical composition comprising 15 to 50% by weight of purified water, 1 to 10% by weight of dipropylene glycol, 1 to 10% by weight of propylene glycol, 1 to 10% by weight of propylene glycol, -20 to 1 to 10% by weight and ethanol to 5 to 20% by weight.

It can be used as a mixed solvent of purified water and dipropylene glycol and propylene glycol and methylglucose-20, and is mixed separately from ethanol.

In the present invention, blue No. 1, No. 227, No. 5, No. 4, No. 40, Carbon Black, or the like may be used as the pigment, or a mixture thereof may be used. The dye may be used in an amount of 0.1 to 10% by weight.

The present invention serves to help color the scalp using dihydroxyacetone as a coloring agent. The dihydroxyacetone is used in an amount of 10 to 50% by weight. When the amount of the dihydroxyacetone is less than 10, the coloring effect may be deteriorated. When the amount of the dihydroxyacetone is more than 50, solubility of the solvent may be decreased.

Even if the same dihydroxyacetone is used, the coloring effect may vary depending on the individual skin condition.

Disodium disodium dithiophosphate is used as a metal ion sequestrant in an amount of 0.01 to 0.05% by weight in order to prevent the action of trace metal ions in the composition and to enhance the stability of cosmetics. It is more preferable to use 0.02 to 0.04% by weight of disodium diiodide. Since the present invention uses a solubilizing agent such as hydrogenated oil, it is possible to lower the upper limit from 0.05 to 0.04, When the lower limit is 0.1, a metal ion blocking effect is observed. However, when the ratio is 0.2 or more, discoloration of the hair line, which is a colored portion, is prevented, so that disodium is contained in dithia in an amount of 0.02 to 0.04% by weight.

The present invention uses hydrogenated oils as a solubilizer to help the various components dissolve in the solvent, preferably 0.5-3 wt% of a Pigment-60 hydrogenated castor oil. In particular, the present invention relates to the use of the abovementioned solvents dipropylene glycol, propylene glycol, and methylgluceth-20 and the simultaneous use of a solubilizing agent, Or absorption of the coloring agent rapidly occurs in the hair, so that the coloring power becomes larger than that of the scalp without the hairs or hair, so that a more natural hair line can be produced.

For the preservative effect of the composition of the present invention, 0.1 to 0.6% by weight of ethyl hexanediol and 0.1 to 0.3% by weight of glyceryl caprylate are used.

Hereinafter, a method of preparing the composition for scalp coloring according to the present invention will be described in detail.

First, 15 to 50% by weight of purified water, 0.01 to 0.05% by weight of disodium dithiophosphate, 1 to 10% by weight of dipropylene glycol, 1 to 10% by weight of methylglucose-20, 1 to 10% To obtain a first melt.

Next, 10 to 50% by weight of dihydroxyacetone is dissolved in the first melt for 20 to 30 minutes to obtain a second melt. Next, 5 to 20% by weight of ethanol, 0.5 to 3% by weight of a phage-60 hydrogenated castor oil, 0.1 to 0.6% by weight of ethyl hexanediol and 0.1 to 0.3% by weight of glyceryl caprylate were added to the second melt And dissolved for 5 to 10 minutes to obtain a third melt.

Next, 0.1 to 10% by weight of dye is added to the third melt and dissolved for 5 to 30 minutes to obtain a fourth melt. The fourth melt corresponds to the composition for scalp coloring according to the present invention.

The dispersion state of the melt is visually confirmed at each step in the production of the composition according to the present invention.

After obtaining the fourth melt, seal it as much as possible and keep it at room temperature, taking care not to let outside air and foreign matter enter.
