Description

Net hair color composition of matter

The present invention relates to an oxidative dye composition for dyeing hair color, gray hair, and bleached hair to a natural original hair color. More specifically, the alkali agent of the oxidative dye agent is sodium silicate rather than conventional ammonia or monoethanolamine. The present invention relates to a dyeing agent composition which minimizes hair damage by dyeing the pH of the dyeing agent with a neutral pH (pH6.5 to 7.0) without dyeing the hair.

In general, hair dyeing is performed to restore aging gray hair to its original color, to change the original hair color to a more attractive color tone and contrast, and to restore the original natural color after decoloring and dyeing.

Hair dyeing can be divided into three types: temporary dyeing, semi-permanent dyeing and permanent dyeing. This classification is primarily based on the degree to which the dye fastens to the hair.

Permanent dyeing agents to which the present invention pertains are made so that the pigment penetrates the cuticle and precipitates pigment molecules in the cortex. By penetrating and adding the oxidant, these dyes decolorize and color.

Permanent hair dyes include vegetable dyes, metallic dyes, mixed dyes and oxidative dyes (organic dyes). At present, the most commonly used oxidative dye is also used in the present invention.

Oxidation tints are also known as aniline-derived dyes, synthetic organic dyes, and aminotints. This is well known as a method of permanent hair dyeing. Since its inception, it has been continuously developed and can produce more than 60,000 shades.

Oxidative dyes are composed of alkali and oxidizing agents.

Alkali, which is mainly used for ammonia and monoethanolamine, swells the hair shaft and helps small dyes settle into the cortex through the hair cuticle, and oxygen produced by the peroxide of the oxidant It starts to react with the molecule.

The aniline dyes react with each other and the color appears on the hair. However, since hair swelling by alkali occurs repeatedly to facilitate the penetration of the dye, there is a problem in that the cuticle and the cortex are damaged.

In order to solve the problem, the present invention uses sodium silicate to make the pH of the dye to be neutral (pH6.5 to 7.0) so that the hair can be dyed without swelling. As an example, the dyeing agent of the present invention was formulated by mixing 0.05% to 5.0% of sodium silicate in the permanent dye composition using oxidation tints.

It is therefore an object of the present invention to provide a hair colorant composition which minimizes hair damage.

1 and 2 is a process chart for explaining the manufacturing method of the hair dye composition of the present invention,

Figure 3a is an enlarged state showing the state of hair before dyeing,

Figure 3b is an enlarged state showing the state of the hair when the hair is dyed using a conventional hair colorant,

Figure 3c is an enlarged state showing the state of the hair when the hair is dyed using the hair dye of the present invention.

The hair colorant composition of the present invention is characterized in that in the permanent colorant composition using oxidation type dyes (oxidation tints), sodium silicate is 0.05 to 5.0% of the total weight of the composition.

In particular, the sodium silicate is characterized in that it comprises 19 to 38% of silicon dioxide (SiO ₂ ), 6 to 30% of sodium oxide (Na ₂ O).

In the hair colorant composition of the present invention having the above characteristics, sodium silicate (Na ₂ SiO ₃ ) is used as alkali pH adjuster of cosmetics, neutralizing agent of acidic polymer resin, adhesive and water softening agent. Aqueous solution has strong alkalinity and is also called water glass.

The present invention eliminates the unpleasant odor of ammonia and amines in conventional dyeing agents by using sodium silicate as an alkaline agent, and minimizes hair damage during hair dyeing by allowing neutral dyeing without hair swelling due to high pH.

The hair before dyeing is kept elastic as shown in FIG. 3A. However, hair using a conventional alkaline dye has a high pH (about 9.0 to 11.0) due to ammonia or monoethanolamine or the like contained in the dye as shown in FIG. 3B. It can be seen that the cuticle layer is broken and damaged. In contrast, the neutral dye of the present invention remained in a state similar to that of natural hair with little damage to the cuticle layer as shown in FIG. 3C.

The present invention provides a hair dye using sodium silicate as an alkaline agent to eliminate the unpleasant odor of ammonia and amines of conventional dyes, and to allow dyes to be neutral in hair without hair swelling caused by high pH. It can be minimized.
